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.

“First you grind the specimen into powder, then you boil it with herbs,” the trader told me. He showed me a box with about 50 dried seahorses in it and explained that, prepared in the right way, the animals act as a tonic to improve kidney and lung function as well as improve men’s virility and cure back pain.
I was at a traditional Chinese medicine shop in Yawarat, Bangkok’s Chinatown, investigating the seahorse trade in Thailand. There were more than 10 traditional Chinese medicine shops on this street, and I found seahorses in almost every of them. Used in medicines, for aquarium display, and as curios, 15-20 million seahorses are traded internationally every year.
Thailand is the biggest seahorse exporting country in the world. Seahorses are controlled under the Convention on International Trade in Endangered Species (CITES), which means that countries that have signed on to this international agreement must ensure their exports are not detrimental to wild seahorse populations. To move the Thai seahorse trade toward sustainability, Project Seahorse and the Thai Department of Fisheries agreed to investigate the situation in Thailand together. It is the first such investigation in Thailand since CITES controls on seahorses came into effect in 2004.
To really grasp the scope of the trade and the impact of these protections, we need to study the route, quantity, price, and species/size composition of Thailand’s dried and live seahorse trade, comparing this new data to the data gathered before the CITES regulations were implemented.
Starting in Bangkok, my Thai colleague, Jaeb, and I interviewed traditional Chinese medicine traders and aquarium dealers We then spent a month traveling along the coastline of Andaman Sea and Gulf of Thailand, talking to fishers and local traders. In Thailand, most of the seahorses involved in trade are caught unintentionally in fisheries that are targeting other species. Fishers collect the seahorses in their catch, dry them, then sell the specimens to local buyers at port. The sales provide important extra income. Local buyers then sell the seahorses to higher-level traders, who then sell to wholesalers, who finally distribute the seahorses to retailers and exporters. Sound complicated? This diagram might help:
The work in Thailand has had its challenges. Although the seahorse trade is legal in Thailand, traders – especially in traditional Chinese medicine retailers – were reluctant to talk about how they sourced their seahorses or about the volume of their trade. Such questions were very sensitive in a business context. Therefore, we had to cross-validate the information we got from people at different trade levels to gain a more complete picture of overall Thai seahorse trade.
Seahorse buyers in fishing villages were easier to approach. Almost every day, they come to the ports to purchase seahorses from the trawler crews, and then keep them until the higher-level traders comes to buy their catch. The first local buyer I met was a man opening a classic old style karaoke bar in a fishing village in Phuket. He was very frank about the trading he does, and even asked us whether we want to go to collect seahorses together. He spends most afternoons and evenings, from about 3 p.m. to midnight, at the port, waiting for trawler boats to come in and making sure he’s one of the first to buy their seahorse catches.
We went with him to the port near his home, which was used primarily for landing the massive bycatch from trawlers, for eventual reduction to fishmeal or fish sauce. Usefully, the buyer soon found a trawler with eight dried seahorses. He bought the seahorses from the crew, as well as many other bycaught animals, such as sea cucumbers, shells, and lobsters. He also arranged for us to interview the trawler captain, who provided us with good information.
The higher-lever traders were more difficult to find, because they usually lived in bigger cities and only occasionally visited the ports where seahorses are landed. Still, we managed to interview a few of them. They told us that they usually sent their seahorses to wholesalers in Bangkok for export, and some of the seahorses were re-distributed to TCM stores in other parts of Thailand.
As our research continued up the trade ladder, a picture began to emerge of the complexities of the seahorse trade and how urgently the Thai government needs to enforce fisheries regulations to ensure sustainability. Stay tuned for the next update!
