1 Shedd Report Seahorses are mainly threatened throughout their range as a result of habitat loss and overfishing. Seahorses often live in waters near shore, they hardly stray away their small home range. In 2003 the World Conservation Monitoring Centre (WCMC) and the United Nations Environment Programme (UNEP) published a World Atlas of Seagrasses, noting that in the 1990s about 15% of seagrasses, a major habitat f, were destroyed by human activities everywhere.Their habitats are being damaged and degraded as a result of coastal development, marine pollution, coral reef destruction, and land-based deforestation, and in turn siltation, etc. Humans take between 15 and 20 million seahorses from the ocean each year. They are collected by divers, snared by shrimp trawlers, sold in souvenir shops and added as an ingredient in traditional medicines all over the world. In Europe, seahorses were used historically for medicinal purposes. To emphasize their overuse, they were are used to treat fatigue, throat infections, asthma, sexual dysfunction, injuries and fractures, heart disease, kidney and liver disease, incontinence, difficult or delayed childbirth, skin diseases, mental disorders, etc. Trade in seahorses is very common. Annual consumption of seahorses in just is about 16 million individuals, which is 45 tons of dried seahorses. The largest importer is China (about 20 tons), Taiwan (about 11.2 tons) and Hong Kong (about 10 tons). The largest exporters are probably India, Philippines, Thailand and Vietnam. The bad thing is they are so vulnerable because seahorses have lengthy parental care and relatively small brood size and survival rate. They are sparsely distributed (not easily replaceable) and have low mobility and small home ranges, which makes recolonization a longish process. Seahorses need to be protected for ecological, biological, economic, and medical reasons. They are important predators on bottom- dwelling organisms; removing them may harm the entire food web. Shedd Aquarium works with Project Seahorse, a global marine conservation group. They help seahorse fishers set up marine reserves where no fishing is allowed. Thus in these areas, the depleted populations are allowed to recover. They have worked with project Seahorse for 15 years to protect fragile
2 populations and the marine ecosystems in Southeast Asia. In 2002, seahorses became the first
