Science is cool... and it's about time we showed kids that!

Midshipmen are not ordinary fish - their songs are loud enough to wake houseboaters, they have rows of small light-producing organs that resemble buttons on the uniforms of naval officers (hence their name), and the males come in two distinct reproductive types, guarders and sneakers.  However when Ruth Sharpe from Let’s Talk Science at UBC (LTS) was looking for a cool science project to get students from underprivileged Surrey high schools excited about BC's marine ecosystems, a strangeness or hook is exactly what she wanted.

Fast-forward twelve months... 
It's lunchtime on a Tuesday and sixty 15-16 year olds are laughing and joking around with their friends. It would be like any other regular school day for these Grade 10s from Kwantlen Park and Frank Hurt Secondary schools in Surrey, BC if it weren't for where they were, and what they were joking about. The sixty students are scattered in groups along Crescent Beach in White Rock, BC where they are sitting on rocks, eating lunch, and talking about how different the last two hours were from a normal day. There is no monotonous hum of an air conditioner today, just as there are no sweaty gym gear, textbooks or whiteboards anywhere in sight. On this particular Tuesday it’s the ocean breeze that provides relief from the mid afternoon sun, while the students don gumboots, garden-gloves and sunscreen, carry clipboards, and learn with their hands by jumping in and getting involved in research. This really wasn't an ordinary Tuesday.

Students were led through a series of stations in teams of 4-5 by Dr. Sigal Balshine, a McMaster University scientist who is a world expert on plainfin midshipman --- today's focal species. Helping Sigal was Ruth Sharpe - from Let's Talk Science at UBC, a charitable outreach organization whose mission is introduce Canadian youth to the wonders and opportunities of science - and volunteers from UBC’s Zoology department well as a number of keen Vancouver Aquarium volunteers. At each station, teams of students were responsible for taking measurements and recording observations about midshipmen biology or their habitat. At one station, students scanned the horizon for potential predators including eagles, crows, herons or any bird they thought capable of eating midshipmen. At another station, students quantified nest density by counting the number of male and female midshipmen, nests, and the average rock length they found in small areas. At each station students learned how to conduct ecological research and used standard scientific techniques - just like real ecologists in the field. They also learned critical elements of the scientific method including repetition, consistency, and control groups. They learned this because Crescent Beach is an active research site. Oh... and the students were able to collect data that contributes to active research datasets to be used by Sigal’s team. So it was important that the students get it right, after all.

Sigal and her team have been using the plainfin midshipmen to study parental care, sperm competition, and the impacts of environmental contaminants (among other things). Midshipmen are super interesting in that males adopt two distinct reproductive tactics, called guarders and sneakers. Guarders aggressively compete for nest sites, which are excavated areas under rocks along sheltered, rocky shores, and sneakers creep into the nests of guarders when a female is present and fertilize eggs that way. Not the most romantic courting behaviour, but cool none-the-less. LTS leader Ruth Sharpe was intrigued. So after Sigal presented her research as part of the UBC biodiversity seminar series in spring 2015 (while on sabbatical at Project Seahorse), Ruth approached Sigal about the potential of using this bizarre fish to get students from high schools interested in science and the environment. It was a unique opportunity that aligned with The University of British Columbia's Centennial Initiatives Fund, a series of grants provided to projects that celebrate UBC's global contributions since it was founded over 100 years ago. 

Ruth and Sigal teamed-up, and were successful applicants for a Centennial grant. The Let’s Talk Science: Ecology, Evolution & Conservation Youth Outreach & Citizen Science Project was born! It was designed to target students who aren't normally given a chance to see how awesome science can be. Kwantlen Park and Frank Hurt Secondary schools in Surrey were identified as schools that would benefit the most from this exposure. Many of the students attending these schools have socioeconomic barriers and as a consequence have had fewer opportunities to learn about the marine environment and conservation. Despite a Grade 10 curriculum that includes topics like food-web dynamics and habitat interactions, the majority of students in these classes had never been on a fieldtrip to the beach, or even had the proper equipment to go to the beach. There is nothing that can inspire curiosity like learning with your hands and through direct observation.  After all, watching a bird dive-bomb a fish is a far better example of a trophic interaction than someone eating a ham sandwich in class.  This sentiment was confirmed by one of their teachers, Liz Bendfeld; "the students were so enthusiastic about the whole experience. I had students who were so proud of their accomplishments that day... For many of my students this field trip was the most excited I have seen them be about science all year."

Ruth and Sigal also wanted to show a different side of science - one that isn't often portrayed in the media. Cool, interesting young men and women from all backgrounds are increasingly the ones who are making the biggest strides in the science world - not just the Sheldon on The Big Bang Theory types. As Sigal put it, " science isn't limited to old white men in labcoats - but anyone who has a sense of curiosity." Surrey teacher Liz Bendfeld reflected this, praising the project for incorporating diversity, "What I thought worked great was the number of female science leaders. It is great for girls to have female role models." It was also important to Ruth and Sigal that students recognize that in some fields (such as ecology) a rocky beach, forest, grassland or coral reef is our version of a laboratory. We're not all standing in a brightly lit room with bloodshot eyes from looking through a microscope for too long.... Not that there's anything wrong with that :)  !

Getting excited about export regulation … really!!

By Sarah Foster

In May I had a really rich experience in the world of marine fish trade.  It was truly fun. I was the point person on the Project Seahorse team tasked with organizing 14 great minds (if I include mine !) to converge on Seattle for a “think tank” on regulating exports in marine fishes of conservation concern.  A career highlight for sure to be in the company of such dedicated people!  Our job was to find common challenges and opportunities for managing wildlife trade among seahorses, sharks, rays, humphead wrasse, European eels, and sturgeons.  These very cool fishes are united as the first wave of fishes to come under global regulations, requiring that no export threaten wild populations.  While that sounds good, the challenge, as ever, lies in the implementation … and that was our focus.  

CITES and marine fishes think tank in Seattle, 2016. 

CITES and marine fishes think tank in Seattle, 2016. 

The global framework for these regulations is called the Convention on International Trade in Endangered Species of Wild Fauna and Flora, CITES.  It’s better known for controls on rhino horn or orchids than marine fishes, which is why our expertise matters.  We addressed myriad questions, in our think tank, all directed at the Big Issue: How can CITES best ensure long-term viable populations of these fishes, for this generation and those to come? 

Our focus was on moving things along to really improve implementation of CITES’ many good requirements, to achieve stronger populations.  So we held ourselves accountable for actually getting work done during the meeting.  The challenge of doing rather than just talking produced a push to define work that could be completed before the next global CITES meeting this September.  We got down to writing persuasive policy pieces, developing draft decisions (actions) for a vote by the 182 CITES Parties (member countries) and determining what campaigns might merit engagement.

One of our key discussions was about how to know if CITES is “working” – in other words, how to assess the impact of CITES or any management intervention on the threatened marine species of the world.  While there are quite a few surveys of fish populations or (more commonly) fisheries, they are patchy in their species coverage while also being erratic and/or inconsistent and/or full of gaps.  Even more worryingly, the documentation seldom measures fishing or trade effort.  So are the numbers referring to individual vessels or the entire fishery, to trips or hours fishing, to days or years? All this vagueness makes it tough to figure out what is really happening, and whether management or exports controls are doing any good.  

To be clear, I’m absolutely convinced that we can take important conservation action with the data we do have.  There’s no doubt, however, that we really need to see some robust monitoring, based around data that can be quickly and easily collected and analysed.  We also need to ensure that data collected in different places, at different times and by different people can be readily combined and/or compared.  These protocols should be straightforward – easily applied by the well-meaning people carrying the monitoring torch. We are talking the basic stuff here – nothing fancy, nothing sexy, but highly essential. 

If we can show there are more fish in the sea thanks to CITES and other conservation tools then we’ll know we are on the right track.  If there aren’t, well, we’ll need to adjust what we do and keep on trucking.  It’s called adaptive management for a reason … and monitoring is a critical component of the feedback loop.

So many thanks to the Paul G Allen Family Foundation for funding this wonderful think tank.  It was one of those gatherings that just worked.  We came away energized, with much to do … but also much already accomplished.


An ocean full of dragons and mermaids

Historical map makers – who worked before the world was fully explored – drew dragons and mermaids at the edges of the known world. Today these mythical creatures have vanished from our maps; the world has been mapped by waves of explorers, surveys, and satellites. We have grown incredibly precise at mapping features as diverse as ocean temperatures, aquifers, and ocean habitats. Yet much remains unknown. We need other methods to map features and human activities that are too small or too ephemeral to be measured by current technology.

In conservation, maps of human activities, such as fishing, and of ecological features, such as habitats, can provide a clearer understanding of where and how humans affect ecosystems and species. Maps that document changes in activities over time can therefore provide a strong foundation for understanding modern-day ecosystems, and the distribution of species and habitats that those ecosystems contain. There has been a growing effort to map fisheries, with most of the success being focused on mapping industrial fisheries that use large, highly mechanized fishing gears. 

For small-scale fisheries, there are relatively few maps documenting where people fish and how that has changed over time. These fisheries – generally characterized by small boats and basic technologies – tend to be poor, marginalized, and often are found in developing countries with relatively small budgets for conservation and management. However, understanding the history of these fisheries is incredibly important because globally they provide an important source of protein and livelihoods for half a billion people. We can learn from the effects of fishing in the past how to better manage fisheries in the future. I like to think of oceans with undocumented fisheries as oceans full of dragons and mermaids – realms that are just waiting to be mapped.  

So I set out to find small-scale fishers and to map where they went, how often they fished there, and what kinds of fishing practices they used. Did they fish with nets or traps? Dynamite or diving? Did they fish in the same places for decades or change where they fished over time? What habitats were located in their fishing grounds?  Corals? Seagrasses? And ever so many more questions about perception and use of the ocean…

Making maps with fishers is tricky – though the reasons seem to vary in different places. In the rural Philippines, where I work, people use maps only rarely. (I’ve written about how hard it was to even find accurate maps of village locations). Most fishing villages I visited boasted a single map of their streets that was hand painted on a wooden board. However, people rarely worked with maps in an interactive way. So before asking fishers to make maps, we needed to provide some lessons in mapping. 

Training fishers and then drawing fishing maps with them was a process that I undertook with a team of local research assistants. We worked with maps that incorporated SPOT-5 satellite images. After scouring the malls of Cebu City to find a large format printer and laminator, I superglued these laminated maps to thin art canvases with hard backs. Flat surfaces were rare in these villages – tables were built from the large round bamboo stalks that Bohol is famous for – so the maps had to serve as a flat surface and base-map at the same time. We placed tracing paper over the base-map when we drew fishing grounds. From the satellite image it was possible to see natural features in the shallow reef areas – grooves and spurs of the coral reef, seagrass beds, mangrove forests – as well as man-made features such as piers and large towns. Since the satellite image was a special kind of picture, some of the coloring was funny – particularly plants on land which showed up as red. We explained these features to the fishers. By pointing out where we were on the map  and how relationships on the map corresponded to relationships in the world around us, fishers started to get the hang of it. 

I’d been warned how hard it would be so I was pleasantly surprised at how readily the fishers became oriented to the map. As with any good lesson, we also tested that the fishers were truly oriented to the map before we turned to mapping where they fished. There was always a great “aha!” moment when they realized that the map they were looking at was actually a funny-colored picture of the place that they lived. During one of our first interviews, at low tide we sat by the coastline looking across the silty reef flat and calm channel to two mangrove-shrouded islands. When the respondent figured out where he was – and that the red areas on the map were the same place as the mangroves across from us – he got very excited and started pointing between what was around us and their location on the map. 

Even after figuring out where things were on the map, most of the fishers were uneasy drawing on the maps. Our strategy to work with this was to draw fishing grounds ourselves, with the fishers acting as the directors through detailed pointing and explaining. Through this method we obtained hundreds of maps of peoples’ fishing histories. 

Here’s an example of what we managed to create.

This became part of our newest scientific paper about mapping coral reef habitats for conservation.  This paper provides guidelines for effective mapping based in coral reefs on conservation priorities. The mapping we did is also part of an ongoing project to evaluate how fishing pressure in the Danajon Bank has changed in time and space – more on this to follow! And these maps have brought us one step closer to brushing away the dragons and mermaids from the edges of what we know. 

Am I really a conservationist?

By Xiong Zhang

Am I really a conservationist? 

As a young marine biologist, I’m kind of ashamed to confess that I had never bothered to ask myself that question until last April, after I started fieldwork to initiate seahorse conservation in China. I took it for granted that I was. Before this project I would confidently tell you that I am a conservationist simply because I study endangered marine animals, like seahorses. But over six-month journey traveling from fishing port to fishing port in China, I began to appreciate what it really meant to be a conservationist … and to understand that I wasn’t there yet.

On the first day of my fieldwork at a local fishing port in Southern China, I saw hundreds of seahorses, landed by a bottom trawler after a two-day fishing trip in coastal waters. I was feeling excited at that moment for being able to see so many wild seahorses for the first of my life. I was thrilled to get my first piece of field data about seahorse fisheries in China! 

Seahorses (Hippocampus trimaculatus) landed along with a few other small fishes caught by a bottom trawler at Qinglan Fishing Port, Wenchang, Hainan Province, China.

However, upon reflection, I feel ashamed of myself. In my excitement I completely overlooked the fact that such a finding means that local seahorse populations, along with many other marine species, can be so easily removed from the ocean! Given that China has hundreds of thousands of bottom trawlers, which all catch seahorses (mostly accidentally), I finally realized that the seahorses that I was claiming to protect face an incredibly uncertain future in China. I am actually swimming against a huge wave, a nationwide overfishing of seahorses along with a culture of using seahorses in Traditional Chinese Medicine — especially in Southeast China. How could I be happy at that moment if I was a conservationist?  I was behaving as if I was merely a researcher who cares more about data than the animals themselves. And I soon realized that being a conservationist has nothing to do with my research unless I put it to good use.

So during the following journey, I started to collaborate and communicate with local colleagues, fishers, divers, non-governmental organizations, and many other groups, in order to mobilize them to protect these highly overfished but lovely species in China with my findings.

Among my communication with more than 500 local fishers, I found that they were, for sure, aware of fisheries collapse and the harm of using destructive fishing gears such as trawl nets. But driven by the competition for decreasing fisheries resources, they were forced to use these destructive gears since they are more efficient in catching fishes than traditional methods (for example hook and line). This results in a vicious spiral with fewer fishes left in the ocean.

A critical step to address the issue is to help fisheries authorities to guide local fishers so they can avoid critical habitats for those threatened marine animals. In my case, I will generate a map of critical seahorse habitats for seahorses in order to meet this end. Local governments can conduct conservation planning based on this map to identify zones where fishing activities should be restricted or relocated. But this cannot be achieved without the engagement of local fishers. Therefore, I need to collaborate with our allies (e.g. local NGOs) to mobilize fishers to become responsible for local seahorse conservation. Only when fishers’ fishing behaviour is changed, can I then be proud to say I am a conservationist. 

Conservation through British high schools

By Owen Raffan

Having come from Britain, after finishing my A levels, I’ve started volunteering with Project Seahorse. Whilst here, I’ve learnt a lot of cool new things. Native species and ecosystems are fantastic. They provide shelter, an income and sustenance for humans. Despite this, we are doing a lot to harm our habitats. Did you know, for every kilogram of shrimp caught by trawlers, 10 kg of other marine life is caught and turned into fishmeal or dumped overboard, dead or dying? I certainly didn’t! Unsustainable methods of fishing, farming and poaching are causing native species all around the world to be decimated. Experts estimate the loss of species we are seeing today is between 1000 and 10,000 times higher than the natural extinction rate. It is clear that this trend is not sustainable. For this reason, conservation of our natural habitats is crucial.

Despite the importance of biodiversity conservation, Project Seahorse has made me realize how little I had learned about it in high school. There is almost no material in the GCSE (taken between the ages of 15 and 16) specification. At A level Biology (taken at 17 and 18, similar to the high school diploma) there are a number of pages on conservation, however it is almost never tested. There have only been 4 questions relating to how conservation works and its benefits across two of the biggest exam boards (AQA and OCR) since 2010. This is a challenge for conservation, as it means the students rarely engage with the topic and subsequently don’t view it as a potential career path or as a global problem that urgently needs to be addressed. I found that I could recall very little looking back to my school days because I wasn’t properly engaged with conservation The first time students are properly educated on the topic is in university. At this point it is too late as relatively few people will be taking the course. 

So what can be done to address this education gap? If more work on conservation was done in schools, you may get a greater interest in the subject; making it more likely people follow it as a career. Students should be taught not only what conservation is, but the benefits and its importance. To engage students, the syllabus should include case studies of current projects which could be followed up with field trips. Personally, I would have found conservation more interesting and memorable if I’d been able to get my hands dirty in a tidal pool or listened to a talk. This hands on approach would further their understanding by showing them how conservation is being implemented. Another key goal should be to aim to make students proactive. This could be done by assigning classes a nearby section of coastline or national park and sending them regular updates or encouraging them to write to government ministers at strategic and appropriate times.

Furthermore, in order for conservation to be successful, the key is public awareness. Many species and ecosystems are being destroyed for commercial value, whether that’s culling trees to make way for crops or killing fish for food. These practices aren’t necessarily detrimental but most methods are unsustainable. Billions of people’s livelihoods are directly impacted by the destruction of ecological habitats. Therefore the public need to be well-informed about how their everyday choices affect their environment and how to make them more sustainable. There are also a lot of little things (e.g. buying only sustainably-sourced shrimp and seafood) that can make a big difference.  Knowledge of conservation has many other benefits, like allowing scientists to quickly collect large amounts of data using public outreach programs and citizen science, such as Project Seahorse’s website Generally, the more people know about conservation, the easier it is for it to be a success.

So how can public awareness be increased? One of the best ways to get key information out to people is through social media. Innovative conservation organizations are now using Facebook, Twitter, and other social media platforms to let people know about their important work. I’m finding my work in social media for Project Seahorse is making marine conservation seem interesting and potentially a future career path. Keeping websites up to date and blogging regularly are both great ways to get people energized and informed. Governments and Non Governmental Organizations (NGOs) being available to the public is key for outreach to work. Useful ways to do this are regional experts giving talks, producing news articles, television shows and podcasts. Whatever method used, it is key that it reaches the maximum number of people. 

To conclude, I’ve learnt a lot through Project Seahorse, I’ve seen the engaging side of marine conservation. I’ll be considering it as a career path now that I know conservation is a vital topic that is more relevant now than it has ever been. Despite this, it is not being taught, in British high schools, extensively enough prior to university. To better protect our planet, we need to work on informing people about conservation both through citizen science and education.

New research leads to conservation win for West African seahorses

There are few things as rewarding as seeing science directly contribute to improved policy. We were thrilled to learn this month that the Convention on International Trade in Endangered Species (also known as CITES, the UN body tasked with ensuring sustainability in the global wildlife trade) recently announced the suspension of all exports of the threatened West African seahorses (Hippocampus algiricus) from Senegal and Guinea — thanks in part to our fieldwork supported by People’s Trust for Endangered Species and the Mohammad Bin Zayed Species Conservation Fund.

Seahorses are listed under Appendix II of CITES (Convention on the International Trade in Endangered Species); they can be legally fished, but a permit is required to export them to other countries. In 2012, CITES became worried about whether exports of the West African Seahorse were indeed unsustainable, prompting an urgent need for field research on this unstudied species and its fisheries and trade. 

During the summers of 2012 and 2013, we studied the local catch and export of seahorses in the West African countries of Senegal, The Gambia, and Guinea, with particular focus on H, algiricus. We visited over 40 different sites over three countries and met with more than 300 fishers, traders, scientists and government officials. This led us to realize that discover the scale of seahorse catch and trade in West Africa was much greater than previously understood. Our results for Senegal suggest that in one twelve month period during 2012-2013, a total of 371,000 individual seahorses were caught, and 184,000 kept as catch. This estimate is far higher than the number reported by CITES or other trade data..  We also examined 250 seahorses, mostly of West African but also short-snouted seahorse (H. hippocampus) in what was by far the largest biological study of seahorses in this region. We also provided the first video of a live West African Seahorse and obtained specimens—with all the required legal permits—that may allow for genetic determination of different populations. 

These findings were communicated to national and global CITES Authorities, and helped provoke the decision in May 2014 to classified exports of West African seahorses from Guinea and Senegal as posing Urgent Concern. As a consequence, these countries were required to meet research, reporting, and management obligations. Such requirements provide useful support in efforts to reduce fishing pressure on wild seahorses in these waters. Unfortunately, though, neither country was able to respond in the required time frames and CITES drew on more of our information to decide on an export ban from these countries.  Our hope is that this notable step will lead to markedly more conservation work in the region, in partnership among researchers, fishers, managers, traders, and the general public. 

This positive outcome for West African seahorses should be celebrated, and is hopefully only the beginning of the story. These are just one of many unsustainably-fished species, and during the course of fieldwork we observed many worrisome practices including finning of sharks, catch of sea turtles, and discarding of many small or unwanted species of marine life. Nevertheless, fishers overwhelmingly noted the importance of sustainability for their way of life, lamented the fact that overarching conditions effectively force them into fishing ever harder for ever less fish, and were interested in learning about potential solutions to this quagmire. A post written during the fieldwork included the thought that: 

“Developing countries face many serious economic and societal problems, such as poverty, which would seem to transcend by far even the most legitimate conservation concerns. Ultimately, these issues belong on a continuum, and need to be addressed together with effective, holistic policies — sustainable fisheries being a step in the right direction. If we only focus on and wait to solve the large-scale issues, we might eventually find that all the smaller conservation battles were lost in the meantime.” 

At least for now, seahorses have provided a crucial win for marine conservation in West Africa. We must now build on this momentum and leverage into even wider environmental and social success. The process may be a long one, but well worth it in the end. 


The seahorse leads the way to sustainable trade in aquatic species

Having laws to conserve nature and knowing how to use them are two different things – if done well, seahorse conservation in the Philippines could pave the way for other species, writes Dr. Amanda Vincent  on World Wildlife Day.

By Amanda Vincent, Chair of the IUCN SSC Seahorse, Pipefish and Stickleback Specialist Group and Director of Project Seahorse

(originally posted on IUCN blog)

Project Seahorse, the marine conservation group I lead, is just about to plunge into new seahorse conservation work in the Philippines. Which is very fitting because that’s really where seahorse conservation began, in the 1990s. It’s also an island country where many seahorse species – ten, to be precise – are found in a great variety of habitats. And a land where people have already made some important changes for the ocean. To bring all this together, we are now working to create a leap forward in management for sustainability, focused on the funky seahorse.

I have a love affair with the Philippines. It all started 23 years ago when, as an aspiring seahorse biologist, I saw an electronic billboard in Berlin that proclaimed seahorses were the “most valuable fisheries export from the Philippines.” Mesmerised, I soon found myself doing detective work, island hopping in this archipelagic nation to interview seahorse fishers and traders.

As a consequence, we were soon helping to set up a marine reserve on a small island called Jandayan, which quickly multiplied to be 35 marine reserves covering the whole region as one part of our national work on seahorse conservation. By that time I had learned some of the local language and Jandayan felt like a second home, so much so that I named my daughter Andaya after the island. As I say, I have a love affair with the Philippines.

I have more mixed sentiments about a UN Convention called CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora. This is the framework for regulating exports of animals and plants that are – or may become – threatened because of international trade.

I led efforts that generated CITES export controls for seahorse species under a listing called Appendix II, the first such regulation for any fully marine fishes. For species on Appendix II, member countries have to limit exports to levels that are not detrimental to wild populations and have to ensure that specimens are legally sourced. Now my team and I are trying to make those controls stick, so that the wild populations really are supported and rebuilt. It can be an uphill battle and depends heavily on national good will and commitment.Our current SOS Rapid Action Grant is building on our many years of effective work in the Philippines and with CITES by linking the two.

By the time seahorses were added to CITES Appendix II, the Philippines had a Fisheries Code that forbade fishing or domestic use of any aquatic species listed by CITES. This seemed like overkill to us – given that CITES controls are solely directed at export trade and only employ bans judiciously – especially given the number of very poor people who had been earning valuable income from seahorses.

So we were pleased when the Philippines adjusted its legislation last year to facilitate sustainable exports of seahorses and other aquatic species listed under Appendix II. That said, there were some worrying aspects to the wording. In particular, the Philippines law allows free trade of aquatic species on Appendix II unless scientists advise against it, whereas CITES actually takes the precautionary approach of requiring declarations of sustainability before permitting export.

We realized that the Philippines would immediately need expert advice on applying CITES to aquatic species, especially given its lack of recent experience. As CITES mandates, trade in these species is fine but only if it does not damage wild populations!

The SOS project is letting us lay the groundwork for the Philippines’ CITES Authorities to get it right for seahorses, as a trial run for other aquatic species. So we have gathered together everything known about seahorse biology, fisheries and trade in the Philippines and distilled it all into briefings for government and NGOs. The next step is to use all that material, leavened with a hefty dose of common sense and realism, to create a plan for regulating exports at sustainable levels, as CITES requires.

As I write this, we are getting ready for the Consultation Forum in Support of the Philippines Eventual Implementation of CITES for Seahorses and Other Aquatic Species. It’s a heavy title for discussions about quirky small fishes, but does reflect the enormous importance of getting this right.

The Philippines’ Bureau of Fisheries and Aquatic Resources – which has to look after CITES for aquatic species – is co-hosting this gathering. With the input of lots of other national experts, we will sow the seeds to grow serious support for marine life that the Philippines exports under CITES. In so doing, the Philippines will become one of the world leaders in seahorse conservation… and add yet further to my devotion to the country.

In memory of Denise Tackett

Denise Nielsen Tackett, 67, was a long-time collaborator with Project Seahorse and respected photographer of undersea marine life.  She is credited with discovering one of the world’s smallest seahorses, named Hippocampus denise in her honor.

Last week (December 2015) we said a final farewell to Denise Tackett, in a place where she spent so much time patiently observing pygmy seahorses, in the Lembeh Strait, North Sulawesi. 

Denise was first in contact with me when I worked on an identification guide to world’s seahorses (published by Project Seahorse in 1999). She sent me a photograph of a small, smooth, orange seahorse the likes of which I had not seen before. Even though I had a strong hunch that it was a new species I couldn’t confirm it without specimens, and Hippocampus denise had to wait another six years before receiving its official name. 

I saw it first in 1999 in the Lembeh Strait on my second dive with Denise. We were also fortunate to be the first people to witness the birth of another pygmy seahorse, Hippocampus bargibanti – 34 babies born in 15 minutes to a male no bigger than the size of your thumbnail. It was a truly amazing experience, and one that put us into serious decompression time to make sure that we avoided getting the bends from our extended stay at 26m. 

Denise and her husband Larry have logged over 6,000 dives, more than 1,500 of which have been in Lembeh Strait. They met on a dive trip in 1983 and subsequently dived throughout the Pacific searching for sponges for Arizona State University’s biomedical research program. They always knew that Lembeh was a special place. Within the first few months of being there they had found several hundred different species of sponge in an area of only a few square miles. After many years of diving for the university they clocked up all the statutory holidays that they hadn’t taken and discovered they had a full six months owed to them! They put sponges aside and focused on their photography, and Denise on her pygmy seahorse research. 

Denise came to know the pygmy seahorses intimately. She watched, described and photographed their activities, courtship, mating and birth. She and Larry produced a short documentary film about them, and a beautiful book about seahorses and the many other species with whom they share their underwater world (Reef Life, Microcosm, 2002). Denise and Larry were always strong advocates for the protection of the Littlest Seahorse and its habitats, even though their work and health ultimately took them away from full-time diving. 

Sadly in February 2015 Denise lost her long battle with cancer (an ironic end for someone who spent so many years searching for biomedically active compounds that might combat cancer). Her dying wish was to be cremated and her ashes scattered in Lembeh where she felt such a strong connection. I promised Larry that if there was a way for me to join him there I would. We were a small group – Jeremy, Nini, Ray, Danny, Larry and I – who took a dive boat out from Lembeh Resort on December 9 with Denise’s ashes. Ray said a short prayer and shared his belief that Denise was now in a place of peace and beyond pain, and Larry also said a few touching words. It was a powerful and special moment, and we all helped scatter Denise’s ashes on the water at one of her favourite dive sites. We also dropped three small bouquets of flowers into the water. Two drifted to the front of the boat. I dropped in the last one, and it resolutely drifted in the other direction. “Just like Denise,” Larry commented with a smile, “always going off and doing things on her own.” She is much missed, but will live on in our memories and in the little orange seahorse that bears her name.

They say that good things come to those who wait. But after what recently happened in the waters of Port Stephens, Australia, I’ve realized that some really cool things happen to those who are just in the right place at the right damn time. On my team's fourth day of research diving we encountered (and filmed) a very, very pregnant male White’s seahorse giving birth.

When I realized I was watching newborn seahorses emerge from his brood pouch, I was mesmerized, but guessed that it must be a common occurrence (this was only our fourth dive, after all). And I was mostly right. Plenty have captured seahorses giving birth on video in aquaria, and even more have seen it without a camera. Earlier this year, in fact, a video of a male Hippocampus kuda (the yellow seahorse) firing babies out like a shotgun went semi-viral. But, again, it was filmed in captivity. I then thought back to every seahorse video I'd seen and it occurred to me that none were of a birth in the wild. It's pretty cool to be a part of something so rare, so when Meagan (my research assistant who took the footage) and I stopped filming, we high-fived and went to the surface. We were positively beaming; not because we'd captured the birth, but because we'd seen it with our very eyes. Did I mention it was only our fourth research dive?  

Seahorses are an iconic marine species for a number of reasons, not least of which is that males give birth. They are a spectacle of nature that are becoming more and more difficult to find in the wild. Luckily, Australia has shown a lot of leadership on marine conservation issues. This type of footage would not be possible in many areas of the world. As incredible as this experience was, capturing and sharing videos like this one is far from our ultimate goal.  We hope that our work contributes to a world where videos and aquariums aren't the only way to observe these incredible creatures.

Tuition, Skype, and Seahorses

By Clayton Manning

Part 2 in this four-part series, Project Seahorse MSc student Clayton Manning ponders the question: "Hey, I'm in Australia doing seahorse research - How did I end up here?"

Now that I was dedicated to study marine biology, I needed to find somewhere to study. Since I was still living abroad, I thought I would keep the momentum going and look at international schools. This was until I was hit with the (very) rude awakening of international student fees. Without naming schools or places specifically it went something like this:
i) Google "school X in region Y for Canadian students",
ii) open webpage,
iii) see $52 000 per year,
iv) close browser,
v) double-check the next day,
vi) re-close browser.

Of course, this is not universal as there are some incredible schools with very reasonable prices and there are others with high sticker prices that have generous scholarship programs to bring the prices down. However not all are like that - Canadian schools included. Being a prospective international graduate student is intimidating no matter how you cut it. Frankly speaking, I wasn't going to go into debt AND live paycheque to paycheque in order to study. At this point I found many Canadian graduate-level biology programs offer a small annual salary so that their incredibly motivated and passionate 20 or 30 somethings. This way they don't have to completely break the bank in order to spend countless hours under microscopes, dredging through literature reviews, or doing painfully hot/cold fieldwork all in the name of science. Seems reasonable if you ask me. Although I'd be giving up international intrigue, studying at home was the best thing for my future.

I immediately pursued professors heading a number of labs in the few schools with solid marine science programs. Although I had an idea of what marine-y I things I did/did not want to study in my head, I was still very open at this point. After all I didn't originally have a specific interest in pine beetles, but I thoroughly enjoyed studying them. By the end of that project I found that I had grown quite fond of entomology and still check up on research coming out of my former lab. Science can make you fall in love with organisms, processes, and study systems you never thought possible - so it's best to keep doors open! I spent hours constructing, deconstructing and tweaking my original opening email. First impressions can matter a whole lot and I wasn't going to let an opportunity slide by because I didn't advertise myself well.

Although most emails I sent got a bite, there were some that didn't. Within the former group there were some that got away after a bit of a back-and-forth, others that I let go, and a small few that... (I'm trying hard to keep this analogy going)... were happy to be caught? There was mutual interest. Note to prospective students: if you don't receive a response immediately, don't fret. Professors are incredibly busy people and sometimes take a little bit of time and coaxing to respond (two months and three emails in the case of one of my more promising candidates). A balance between patience and persistence is key. 

By the time December rolled around (still 9 months before I started) I had narrowed it down to two professors studying very different things in very different places, from different universities. Despite being far more comfortable meeting face to face, the large distances forced me to get very used to Skype - a tool that I'm finding more and more useful as I probe (/annoy) academics around the world for useful bits of advice as I head into my field season. Note to students: I joke. Academics are extremely friendly and almost always more than happy to talk with you over Skype. They can offer you insight on topics and details that you can’t find in a Methods or Results section. There were a few days I had to have Skype interviews at very strange times of the day. My eventual supervisor encouraged me to talk to as many people in her lab as possible so my already variable teaching schedule was made even weirder with all of these inter-continental chats. But a huge reason I sided with Project Seahorse is because of the time they invested in me. When I showed up on Day 1 last September I had already met or corresponded with many of my lab mates, which made the transition much easier. One less thing to be overwhelmed by. I was now based at UBC in Vancouver, and going to study seahorses. 

But where would I study them?

The Marine Biologist (Part 1)

By Clayton Manning

In this four-part blog series, Project Seahorse MSc student Clayton Manning ponders the question: "Hey, I'm in Australia doing seahorse research - How did I end up here?"

Back in April 2013 when I made the decision that I wanted to go to grad school I had no idea that I'd end up going to university in western Canada, or doing field work in Australia. The only thing that was truly clear is that I wanted a Masters, and I wanted to do field work. Since then I've researched, deliberated and eventually crossed out a list of universities in four different countries, and field work in another six. And all of that was after the not-so-easy-for-an-Alberta-boy decision to study marine biology and conservation. Although at times it's been stressful not knowing where I'm going, what I'm going to do, or who I'll be doing it with, sometimes it's this uncertainty that makes the final destination so rewarding, and the road there so exciting.

The journey starts in Japan, where I was living, working, and consuming copious amounts of ramen. After a grand total of about two months at a real job in this ancient land, I decided that I wanted to go back to school. After a research hiatus of less than half a year, I was already yearning to do more cool science. Plus, I'm more of a shorts and t-shirt all-year kind of guy, and the suit-and-tie thing really wasn't doing it for me. I wanted out; not out of Japan, but the Japanese working world. So after Google translating 'graduate school' into 'daikakuin' on my phone, I immediately started searching for grad programs in Tokyo, Osaka and Kyoto. I had no idea what I wanted to focus on, so I looked far and wide for anything under the (land of the rising) sun.

Turns out, not so surprisingly, that to study anything in Japan you need to speak some Japanese... and at the time I wasn't even good enough to read the damn eligibility website to find out that my language skills made me ineligible! Learning a second language seemed like a challenge, and I was up for it. I had about 16 months to learn as much of one of the world's most complex languages as possible, and about six to get good enough to qualify for Japan's 文部科学省奨学金, the Monbukagakusho scholarship. It's similar to NSERC - essentially the government pays you a salary to go to school, cover your tuition, and drink beer. However if I learned anything in Japan, it's that nothing in Japan is as easy as it seems. Ever.

The major hitch in my plan to become an incredibly sophisticated foreign-language speaking researcher is that in order to pass the second round of cuts, I would need to do a face-to-face interview with the Japanese consulate IN CALGARY to be eligible for a scholarship to do school where I was already living. A 16 000 km journey to do school 50 km away. I was somehow being penalized for actually living in the place I wanted to study. Skype/phone calls or an interview with the actual Japanese government in Tokyo was not an option... believe me, I checked. Deciding that I didn't want to take holiday time to spend $1200 to fly back to the city I had just escaped to simply increase my chances of making minimum wage, I crossed Japan off the list. Despite the best year of my life, and learning to love teaching, I would leave a year and a half later.

Parksville, Vancouver Island, BC, Canada

Parksville, Vancouver Island, BC, Canada

It's amazing how things can stick with you. After eliminating Japan, I decided to change my selection criteria from a location-based focus, to subject-based. It was not long after, when searching for scientific inspiration and trying to decide on a field of biology to study, I thought back to a time a few years prior. It was one of those perfect B.C. summer days and a few friends and I decided to a stroll along one of the vast beaches in and around Parksville, on Vancouver Island. At some point that afternoon we stumbled upon an older man who looked to be giving a lecture as he was surrounded by a semi-circle of people hanging on his every word. Turns out he was a biologist and he was discussing the marine ecosystem - the flow of nutrients and water, what was eating what, and how human activity was changing things (mostly for the worse, not surprisingly). Although I had been exposed to what he was saying in a first year biology course during my undergrad, it really resonated with me that day because it seemed more visceral. It wasn't being said in front of a PowerPoint presentation - his classroom was literally in among the subject matter. I'm not sure if anyone was as touched by his storytelling as I was but everyone seemed to be enthralled, even if it were only for a minute or two as they passed by.

The four of us (all Environmental Biology grads) would talk late into that night about life, biology, grad school possibilities, and which of our specific interests was more interesting. But that marine biologist sparked something in me that had existed since studying marine and freshwater ecology during my undergrad. Something about the idea of being underwater and not studying insects really got my science juices flowing (Read my blog about studying these topics here). I had been inspired by marine courses in the past, but I was from Calgary and that is not how things were done. But I was living in Japan now, and how do they say it... "The world is your oyster"? Fitting. 

I then did what anybody in my shoes would do - I put the Planet Earth "Shallow Seas" episode in my DVD player, watched it; YouTubed the Great White shark on seal attack a few times, and was set. I was going to study marine biology!

But where to study?? 

Beyond traditional pollutants

By Prof Sigal Balshine

Prof Balshine spent a year collaborating with us at Project Seahorse in 2014/2015. This blog is about her research in Hamilton, Ontario.

Flush!  The first show to ever feature a flushing toilet was “All in the Family”. Back in the early 1970s bathroom business was still considered a highly taboo subject, and a fairly unsuitable or risky topic for network television. But we all use the toilet.  In Hamilton alone, toilets are flushed about 2 million times a day.  That is about 1500 flushes per minute.  And when the 720, 000 people, who live and work all over the Greater Hamilton metropolitan area, use their bathrooms, it’s not just water that is being flushed down that sink, bath or toilet. The wastewater or “sewage” in Hamilton is treated by three large wastewater treatment plants that collectively “clean” over 520 million liters of wastewater each day. All three of these plants are extremely well equipped to deal with our bodies’ natural wastes, feces and urine. 

But these treatment plants have a much more challenging time filtering out pharmaceuticals such as antibiotics, aspirin, and birth control pills or personal care products like sunscreen and deodorants, compounds that unfortunately also end up in wastewater whenever we use the toilet, shower, sink or laundry. The drugs we take are not entirely absorbed by our bodies so they and the cosmetics, perfumes and soaps that we use are passed into the wastewater stream. 

But why should we care if there are small residues of pharmaceuticals and personal care products in our wastewater?

Well, once our wastewater is treated and cleaned up, the liquid component, known as effluent, is pumped right back into our rivers, lakes and oceans.  In Hamilton, this treated wastewater gets discharged into Hamilton Harbour, and into Cootes Paradise Marsh. All of the City of Burlington’s wastewater is also discharged into Hamilton Harbour. Many different fish, amphibians, reptiles, birds and even mammals live in these aquatic habitats.  And these water bodies are where we swim and play, and they are connected to Lake Ontario, where we get our drinking water.

How does the treated effluent in these areas impact the wildlife and the ecology of the Bay? The truth is we don’t really know.  It is likely that many aquatic animals encounter treated wastewater everyday.  Cootes Paradise, for example, is an environmentally sensitive wetland, is used by over 25000 water birds as an annual migratory stopover spot and by over 60 species of fish as a breeding and nursery ground (with over 10 million young produced there each year). Unfortunately, removing the removal of pharmaceuticals and personal care products (PPCPs) from wastewater is technologically challenging and prohibitively costly to filter out, so more and more of these compounds are ending up in our watersheds.

More worryingly still is that when many PPCPs mix together they produce a complex cocktail and the impacts on wildlife exposed to these mixtures are really not very well understood. Recently in Sweden, Brodin and his colleagues [link to reference?] showed that European perch exposed to just one of these compounds, a mood-altering drug, were far less social. Fish that are less social won’t group together and without the protection from schooling together are at much higher risk of predation. 

In my laboratory (ABEL), we too have found that fish from highly impacted sites in Hamilton Harbour, move less and take unnecessary risks in the presence of predators (Marentette & Balshine 2012). Changes to animal behaviour or physiology can be thought of as a type of early warning system.  The fish may not die but if they look or act strangely something might be wrong.  Fish and other aquatic organisms can be used as firstline indicators.  They are the canaries in the coal mine, for compounds that might affect the health of our aquatic habitats and the quality of our drinking water. But first we really need to understand how precisely wastewater effluent influences biological function in animals that encounter it regularly.

To this end, my research group at McMaster University, the Aquatic Behavioural Ecology Laboratory (ABEL), has begun a research study.  Joining forces with Dr. Graham Scott’s research group from the McMaster Biology Department, the Royal Botanical Gardens, and the City of Hamilton’s Wastewater division, we are examining how treated wastewater effluent influences fish behaviour and physiology. Graduate students Erin McCallum and Sherry Du, and their research assistants, are caging fish in locations ranging from the wastewater plant’s treatment ponds and next to the effluent discharge pipes all the way to a distant clean site far away from the wastewater effluent. The fish are exposed to different amounts of wastewater effluent in these cages for a month. We then test their behaviour and their physiology, looking at traits that are important for reproduction and survival.  We are using two species of fish, the round goby and pumpkinseed sunfish, both ecologically and economically important species in Canada and the Great Lakes.  We want to understand if treated wastewater effluent, even at very low doses, can alter biological function of the animals that encounter it. 

So what can you do about the problem of pharmaceuticals and personal care product contamination? First, always make sure to take advantage of drug take-back programs at your local pharmacy or local waste collection station. Never flush remaining drugs into the toilet or wash unused pills down the sink. Second, whenever possible use less harmful organic cosmetics and cleaning products.  If there is a choice between several different drug options, consider the respective environmental impact and pick the most ecofriendly compound. Third, encourage the city and the province to more strongly protect our natural lands and water bodies. Eventually there will be further advances in removal technology, and possibly even legislation that will better protect our oceans, rivers and lakes. Until then we need to make sure that we know how to accurately detect and measure these chemicals in water, in sediment and in the organisms that live in aquatic habitats.  And of course we really to figure out what the consequences of PPCPs are on ecosystem function and on human health. 

So the next time you flush, take a minute to think about how we can all work to protect water, our most precious renewable resource.

Taking action for seahorses with Marine Conservation Cambodia

By Lindsay Aylesworth

In our latest Field Notes, Project Seahorse PhD candidate Lindsay Aylesworth(@l_aylesworth reflects on taking action for seahorses in Cambodia.

My most recent seahorse adventure brought me face to face with a man who has a sixth sense for seahorses – Paul Ferber.

Paul runs a volunteer funded group called Marine Conservation Cambodia. They have been working in Cambodia since 2008 to monitor seahorses around the coastal islands and support the local fisheries department to stop illegal fishing. I had met Paul by email a little over a year ago, while working on a collaborative paper about Hippocampus mohnikei, one of the seahorse species found in both Thailand and Cambodia. After hearing about his expertise in seahorses and learning of his group’s mission, I decided to visit my colleague and see what seahorse experiences Cambodia had to offer.

To be honest, I wasn’t quite sure where I was going. Paul said he was located on Koh Seh Island, which didn’t mean much to me initially. Turns out, Koh Seh is located in the southern part of Kep Province about a three hour drive from Phnom Penh Airport. By boat it takes roughly one hr to reach Koh Seh from the pier in Kep. It is the furthest island from the mainland and the closest island to Vietnam. The island is uninhabited except for a small marine police station and of course Marine Conservation Cambodia. The island is pretty small, and it takes about an hour to walk around it depending on the tides.

On my trip out to Koh Seh Island, I saw how serious Paul and his team were about protecting the seagrass beds in the area. There are many boats that illegally fish in Cambodia, and these coastal waters are also home to dense seagrass and coral reef habitat. As we were making our way to Koh Seh, the Marine Conservation Cambodia team had spotted a trawler fishing illegally, in this case from Vietnam, and the team went into action. One minute there was a Cambodian guy relaxing on the boat in his board shorts and tank top, and the next minute he’s putting on his official Fisheries Department uniform and making his way to the bow of the boat. We approached the boat, and after an exchange of words in Khmer and some angry gesturing, the fishermen pulled up the net, dumped the fish and seagrass back into the ocean and headed back to sea in the direction of Vietnam. This would turn out to be a typical experience for the Marine Conservation Cambodia team since they work full time with the local fisheries staff to increase the number of local patrols of the area.

My admiration for this group of passionate and dedicated conservationists increased throughout my short four-day trip out to the island. Paul built the base-camp and operations on Koh Seh island from scratch. He chose the location in particular due to the diversity of underwater habitats surrounding the island. The accommodation is basic – simple huts with bucket showers and electricity only at night – but the scenery both above and below the water is worth it.

Learning opportunities abound to volunteers who spend time on Koh Seh – with the local staff trained in fish, invertebrate and marine habitat identification – and of course seahorses. While out there I gave an iSeahorse Training workshop to the volunteers and staff and shared our training material with my fellow seahorse lovers. After the workshop, the volunteers and I jumped in the water for a practice dive to work on species identification and practise the iSeahorse data collection method.

Paul’s reputation for finding seahorses is well deserved. Within minutes he can spot a seahorse, which compared to some of the research I’ve been working on in Thailand - where seahorses have been hard to find to say the least - is amazing. In front of the base camp is a 300 x 800 m seagrass bed- with multiple species of seagrass and seahorses. During our iSeahorse practice dives we spotted the two most commonly seen species around Koh Seh – Hippocampus kuda and Hippocampus spinosissimus.

The future is filled with collaboration for Paul and me. We created a plan to build on the research I’ve been working on in Thailand about appropriate levels of effort needed to monitor local seahorse populations. Seahorses can be hard to find because of their ability to camouflage with their environment and as a scientist it’s important to understand how your ability to detect (find) seahorses in different habitats impacts your results. In Thailand I started to explore these ideas in sandy soft bottom habitats – the simplest habitats to find seahorses. The numerous habitats around Koh Seh and the neighboring islands are perfect for building on this research to include seagrass and shell habitats. During my short time there, I worked with Paul and his staff to create a research protocol and explain data collection procedures. We also discussed marking the seahorses in front of the base camp in the seagrass bed. The area acts as a de-facto marine protected area, since Paul and his team patrol it and would be a great research opportunity to study the population dynamics of seahorses in the wild. Sadly, my time in Cambodia was too short to put this plan into action, but we’ll be working towards starting this research project shortly.

My visit to Marine Conservation Cambodia was inspiring. It reminded me of my first marine conservation experience in a remote part of coastal Mexico where I combined scuba diving and science for the first time and the marine biologist inside of me was born. It was also refreshing to see something accomplished in the name of conservation, i.e. the illegal trawling boat dumping out its catch and heading back to where it came from. It can be challenging working in Academia - publishing research in journals and writing policy briefings for government officials – and I’m often left wondering if it makes a real difference on the ground. Are the natural resources in the ocean where I work better off at the end of the day based on my actions? In the case of Marine Conservation Cambodia, the answer is clearly yes. Paul’s group and his setting will undoubtedly inspire the next generation of marine conservationists for years to come.

Murderers, Cannibals and Spanish Dancers

By Kyle Gillespie

At the beginning of chapter 6 of John Steinbeck’s Cannery Row he tells a story of murderers, cannibals, Spanish dancers, ferocious cats, frantic children and pulsing rage. Variations of the word “murderer” are used three times and we hear phrases like “leaps savagely,” “moving like a gray mist,” and my favourite: “The smells of life and richness, of death and digestion, of decay and birth, burden the air.”

This is not a story of seedy back alleys, Amazonian adventures, or fields of war. No. Here, he is describing a stretch of rocky intertidal on a sunny, summer day. A place that many of us would look at and say to ourselves: “How pleasant!”

In truth, octopuses are not murderers, hermit crabs are not frantic children, and sea slugs are not – to my knowledge – Spanish dancers waving their dresses. But the author has done something remarkable: in a few sentences he’s created a picture in our minds that is both vivid and relatable. We care about the characters and their fates. The dancers and thugs we meet are far closer to human experiences than the reality of sea animals going about their daily rituals of eating, surviving and finding mates. And I think it’s that quality that makes someone who would usually be indifferent to the ocean, become enthralled by the imagery that now fills their minds.

This is something that stuck with me last August when I attended COMPASS’s Scientific Storytelling Workshop in Glasgow, Scotland. When it came time tell my science story during the International Marine Conservation Congress, it was important that I create vivid imagery and make my study animals relatable.

Like Steinbeck, I’ve been enamoured by the ocean for many years and I’m now lucky enough to study it as a graduate student. It is an incredible, exciting place that is out of sight for many and out of mind for most. Until I have the problem of being overrun with requests for comment on sea cucumber feeding strategies or overfishing, I will be guilty of using vivid, relatable imagery – if even just to bridge the divide between our lives and life in the seas.

The ‘other’ seahorse experts: on the importance of listening to fishers

By Xiong Zhang

This is the third in a series of blogs about fisheries and conservation in China. Read part one and part two

In a recent post, I wrote about how fishers have much to contribute to the science, conservation, and management of fish populations. As a young marine biologist I’m keen to learn from anyone and everyone, including these often-overlooked ‘experts,’ so beginning this April I’ve been interviewing fishers across China about seahorses. The goal of my research (funded by Disney) is to establish a baseline knowledge of the country’s seahorse populations.

After nearly three months and hundreds of interviews, I’m even more convinced of the importance of fishers’ knowledge.

At first I was afraid that they would not bother to talk with a stranger from a world far away from their own. But when I started to chat with some locals the first day at a fishing port in Linshui County, Hainan Province, I was surprised at how open and welcoming some of them were.

Generally, I interviewed two types of fishers. The first is commercial, and the other small-scale. Commercial fishers are those working on large fishing vessels (~ 15 to 50 m by length) who go fishing far away from the port. They are usually hired by a wealthy businessman who owns the vessel and has direct ties to the seafood business. The crews of five to 10 people consist of captain, a chief engineer, and a few fishers on deck. It is the fishers who operate the nets and collect and sort the catch. Commonly used gear that catch seahorses are shrimp trawls and drift gillnets.

These workers, with a monthly salary of US $700 to $1200, catch seahorses as bycatch (i.e. the seahorses are caught incidentally as part of a targeted catch of species such as shrimp or crab), collect them from the nets, and sell them to local traders for extra income back at the port. Sometimes the ship captains are part of this “seahorse bonus” scheme, especially when the seahorses are abundant and the fishers directly target them in specific waters, such as Zhoushan Fishing Ground (close to the estuary of the Yangtze). The fishers know where and when to catch the seahorses, but they have little ability to discriminate between species — to be honest, this is not easy even for an expert. Unlike us scientists, who name seahorses with Latin words, the fishers give seahorse species common names based on their size or the color. Not necessarily the best way to differentiate species. Their knowledge usually ends there, though some fishers have been able to provide me with a rough map of seahorse population distributions.

The second type, small-scale fishers, are those who own a small fishing boat, usually a wooden vessel no longer than 10 m, and only fish in coastal waters close to their fishing port or village. There are usually two or three fishers – often from the same family – working on each boat, with a total annual income of between US $10,000 to $20,000. They catch seahorses with many different types of gear. The most frequently used are shrimp traps, shellfish trawls, crab traps, and drift gill nets. Although they catch many fewer seahorses than their commercial counterparts, they tend to know a lot about seahorse behavior and ecology.

Here are a few of their insights: that some seahorse species hide in the rocky seafloor, between the gaps between shellfishes (e.g. mussels), and in empty shells; that other seahorses prefer to live on muddy seafloor with seagrass or macroaglae in estuaries; that they sometimes drift to shore with their holdfasts (e.g. seagrass) in summer, while the autumn tides drive them to deep water; that wild seahorses can make a “goo-goo” sound, which I’d only ever heard about from some aquaculture literature.

A few fishers I met even tried to culture seahorses because their children love them, and from their experiments learned how seahorses swim and how they give birth. One fisherman in Shandong Province claimed that he cultured what was probably a Japanese seahorse (H. mohneikei) in a small plastic bottle for more than one month in spring without feeding but only changing water every three days. (More likely the seahorse was feeding on zooplankton already in the bottle, but an interesting anecdote nonetheless!)

My interviews with Chinese fishers are not yet finished, but I’m already confident that their knowledge will inform the science, conservation, and management of seahorses in China.

“Surely that can’t be natural.”

Those were the words that went through my head when I first saw the strange blue, red, and bright green fibres under my microscope. Recently returned from a scientific expedition on the R.S.S. James Cook, I was back in London, studying deep sea mud collected from the South West Indian Ocean (SWIO). The purpose of the two-month expedition was to assess the biodiversity of seamounts (undersea mountains), and my role was to investigate the diversity of nematode worms that live in the sediment on their slopes.

Instead of microscopic worms, though, I was looking at microplastics, tiny synthetic fibres or particles. When plastic bottles and other garbage are dumped in the ocean, they eventually break down and microplastics are what you get. Studies have shown that these tiny pollutants can have negative physical and chemical impacts on a range of organisms and ecosystems. Already full of chemical additives from the initial manufacturing process, they absorb further organic chemicals and heavy metals once they are in the ocean, thanks to their large surface-area to volume ratio. When microplastics are ingested or otherwise absorbed, these chemicals can and often do accumulate in the tissues of all kinds of animals, causing untold harm as they’re passed along the food web.

First documented in the early 2000s by Prof. Richard Thompson of University of Plymouth (Thompson et. al., 2004), microplastics have been found in many different environments across the globe, from mangroves to Arctic ice. However, one area they had not been documented was in the deep sea, so I set up a collaboration with Prof. Thompson and a number of other researchers to obtain sediment and screen for microplastics from deep-sea locations across the globe.

We recently published our findings in the first-ever report on microplastics in the deep sea (Woodall et. al., 2014). We showed that they are so abundant, the bottom of the ocean could be considered a sink for this pollutant. More research is needed to understand the true impact of microplastics on the environment, but something we can say right now is that these pollutants are so small and the oceans so vast that clean-up is never going to be an option. The first, and best, step is to prevent litter from getting into our oceans in the first place.

I continue to study the impact of microplastics on the deep sea environment at the Natural History Museum in London, while also documenting patterns of litter found on the seabed, and developing methods for working with microplastics.

As a child, I was raised to cherish nature. I grew my own vegetables and rode my bike to school. I think I was eight years old when I realized I wanted to save the planet. I was furious whenever I saw someone litter, going so far as to throw rocks at people dumping their garbage on the street. (Luckily my aim was — and still is — terrible. I never hit anyone). As I grew older, my love for the earth translated into a passion for biology, geography and environmental science. I’ve travelled across the world to learn about how humans interact with the planet — what we rely on to survive and what our impact is as a result.

But the truth is, saving the world often feels like an impossible challenge. As a conservation biologist, it’s easy to feel overwhelmed by all the bad news — the species extinctions, the destructive resource extraction, the exploding human populations, and wave after wave of urban development at the expense of nature.

That’s why, recently, I was thrilled and a little overwhelmed to be surrounded by scores of other, likeminded young scientists who want to devote their lives to improving how we do research, developing sustainable livelihood programs, and ultimately saving threatened species from extinction. I was participating in the 16th Student Conference on Conservation Science, held in Cambridge, England. A hundred and twenty young scientists from 60 countries were in attendance, along with four plenary speakers and plenty of professors and professionals. The conference lasted three days, each of which was jam-packed with student talks, poster sessions, workshops, and plenary talks. The topics ranged from conserving big cats, to regulating trade, to asking sensitive cross-cultural questions, to understanding the interaction between policy and human well-being in a conservation management framework.

I really enjoyed learning about species I’d never even heard of, like the guiña, a small cat in Chile, and the saiga, a critically endangered antelope in Mongolia. I was fascinated by methods commonly used in terrestrial conservation, like camera traps. Who knew it could be as easy as placing a bunch of cameras on trees to figure out community composition?

I was lucky enough to give a talk, and I enjoyed the chance to shift the terrestrial-heavy focus to marine systems for a little while. I focused on the livelihoods of fishers on Phu Quoc Island, Vietnam, many of whom rely on seahorses as a source of income. The island is a unique area where many different gear types catch seahorses, and some boats even target seahorses specifically. At least 150,000 seahorses are caught and landed off the island each year — a large portion of the overall catch in Vietnam. From a conservation perspective, ensuring the survival of seahorses becomes much more complicated when people fish for them directly.

It was inspiring to have so many people come up to me afterwards to chat about my research, wanting to know more and offering their insights to the complex task of managing seahorse fisheries in data-deficient situations. I was offered advice about community engagement, with examples from the Caribbean and Indian Ocean. I was also able to draw from terrestrial methods, like land stewardship, to help brainstorm ways to make Vietnam’s seahorse fisheries more sustainable. I quickly became friends with students from Italy, England, Brazil, South Africa, Australia, the USA, and India. Hearing their stories and relating to them on so many levels was a powerful experience.

As young conservationists, our generation is more interconnected than any before it. The possibilities for collaboration are dizzying, and with new technologies making it easier than ever to study wildlife and monitor threats, it’s impossible not to feel optimistic about the future. I left Cambridge convinced that we are going to change conservation and improve the world we live in.

I look forward to making the eight-year-old version of me proud.

The Gulf of Mannar's trawling problem

By Tanvi Vaidyanathan

As a young marine scientist who grew up in southern India, I have long been captivated by the Gulf of Mannar, and I am hardly the only person. With its iconic seahorses, charismatic sea cows and thousands of other marine species, the area is known for its incredible biodiversity. Located between the southeastern tip of India and the northwestern tip of Sri Lanka, it is home to mangrove and sea grass habitats- ideal feeding and breeding grounds for many species.

Unfortunately, the Gulf of Mannar is also known for its longstanding problems with overfishing and destructive fishing practices. Since the introduction of trawling in the 1960s, the area has come under incredible pressure from commercial fisheries and small scale fishers alike. The widespread use of push-trawls (‘thallu madi’) — adopted by artisanal fishers keen to keep up with the commercial fisheries — has been particularly disastrous. A modified gill-net that targets shrimp, the thallu madi also catch juvenile fishes, cephalopods and other animals. This gear is often operated over shallow sea grass habitats, bringing up a fair number of syngnathids (seahorses and pipefishes) as bycatch.

Over the past few decades, a number of conservation measures have been introduced in the Gulf of Mannar, including a “Marine National Park” designation by the Indian government in 1986, a UNESCO biosphere park designation in 1989 and a ban on seahorse fishing in 2001. But, it is not clear if they have made a difference.

Take seahorses as an example. In the five years leading up the fishing ban, exports were estimated to be around 3.6 tons per year. In 2001-02, the year following the ban and when the next estimates were carried out, exports actually increased to somewhere between 4.35-9.75 tons, potentially due to growing demands for seahorses from other Asian countries. In the nearly 15 years since then, the enforcement has been spotty at best. Illegal trade happens to be a major issue, though the true extent of it is not known. What we do know is that the region is home to around 150,000 people, over 70% who still depend on fishing for their survival. Over 1200 mechanized and 1100 non-mechanized fishing vessels enter the Gulf of Mannar on a regular basis.

We also know that demand for seahorses still exists. In India, the trade feeds the global traditional Chinese medicine industry. Seahorses have also emerged as an alternative to the declining sea cucumber trade, the majority of Indian seahorses exported to other countries are sourced from the southeastern coast, mostly from the Gulf of Mannar and the nearby palk bay. While a small portion of the seahorses come from a targeted fishery, most were landed as incidental catch (bycatch) from trawls operating in the gulf. Prior to the ban, seahorses were thought to represent 60 to 70 percent of the fisher’s income in some areas.

What impact have the Indian government’s conservation measures had on seahorses and other marine fishes? Likewise on the livelihoods of fishers and fishing communities in the Gulf of Mannar? In this context, how does one balance the need for conservation with the need for food security?

These are some of the questions I intend to answer as part of my PhD work with Project Seahorse. As I embark on eight months of intensive field research in the Gulf of Mannar and beyond, I will be posting my findings in this space. Stay tuned!

You say 'falsification,' I say 'validation': taking a multidisciplinary approach to conservation

By Ting-Chun Kuo

Success in conservation requires people from different backgrounds to work together. Seahorse conservation is a case in point, where biologists, fisheries scientists, policy makers, businessmen, social workers, the media, and many others need to work together to achieve the goal of protecting these iconic animals from overfishing and other human pressures. Biologists study the size, health, and survival of seahorse populations. Fisheries scientists study how people use seahorses and assess the sustainability of their use. Ideally, policymakers then incorporate information from these biologists, fisheries scientists, and other stakeholders such as local communities and non-governmental organizations (NGOs) to design population management tools. Media and advocacy groups meanwhile play an important role raising public awareness around the need for these and other protections.

The process can be slow and frustrating, of course — people are used to viewing a given issue through their particular lens, which can cause them to overlook other important perspectives. But from my own recent experiences, I’m convinced that an interdisciplinary approach to conservation is the only way forward. 

Since I started working in conservation, I’ve made a point of learning skills from multiple disciplines and making an effort to work with people with different backgrounds. Which is why I was so excited when I learned about the Duck Family Graduate Workshop at the University of Washington’s Center for Environmental Politics. It was an excellent opportunity for people working on different environmental issues from different perspectives to interact with each other. The workshop happened over two days in March in Seattle. Every participant submitted a paper about their work for broad-based, intersciplinary discussion at the workshop.

The workshop included faculty and students from disciplines ranging from political science to economics to law. Lindsay Aylesworth, another PhD student from Project Seahorse, and I were the only natural scientists on hand. I presented my work, which analyzes how an international agreement (Convention of International Trade in Endangered Species of Wild Fauna and Flora, or CITES) affects the trade and conservation of seahorses, while Lindsay shared her experience of using local people’s knowledge to understand the distribution of seahorse populations. During the workshop, we had a great time stepping back from the work we have been immersed and absorbing other people's perspectives on it. We were also exposed to a wide range of interesting research on other issues as water usage, green buildings, air pollution, and climate change.

Although we went in mentally prepared, both Lindsay and I were still surprised by how much of an obstacle language can be to communication. Every discipline uses a different dictionary, or lexicon, of technical words. One example was when Lindsay asked a politics student how she ‘validated’ her model after collecting the first round of data. After a couple of minutes of slightly confused discussion, the student suddenly realized that Lindsay was talking about what her discipline calls “falsification.” Equally, the same word can have different meanings in different disciplines. For example, in natural science, “diffusion” means how ions or molecules move from higher concentration to lower concentration. However, when, in political science, people say “policy diffusion”  they mean how the policies of one country influences those of others.

During the workshop I often thought of my PhD supervisor, Dr. Amanda Vincent, and her constant refrain that we must always be on guard against jargon. Wherever possible, in public and multidisciplinary forums, we need to use language that even an eight-year-old child can understand. It was at the Duck Family workshop that I realized how true this maxim really is.

Once we established common linguistic ground, the workshop group had many enlightening discussions. Their different perspectives shook me out of my usual thinking — which is to focus on whether there is a universal principle to explain the patterns in my data — and spurred me to think about the “context” of my case studies as well. My research requires quantitative analysis on economic data, as well as qualitative interviews to understand why people make the economic decisions they do when it comes to trading seahorses.

When I am in the field later this year, I will make a point not just of validating ‘hard’ economic data; I will also investigate the perspectives of traders to better understand how their thinking and behaviour might affect these larger trends in the trade. By incorporating many different research methods, I will look into the questions from many different angles, and hopefully the information from multiple sources will help us have a more complete, thorough understanding of the global dried seahorse trade.
