A conservationist’s fight to save seahorses
Print Edition
A 7-inch (17.8-centimeter) creature with a head resembling a horse and a monkey-like tail glides gracefully out of a dark coral crevice off the Cambodian coast. Master of camouflage, unrivaled as a hunter and a much-loved figure of ancient myths and legends, the seahorse may be spiraling toward annihilation after surviving beneath the waves for some 40 million years.
Taking photographs and detailed notes, two divers swim through turbid water to spot the male in the crevice and a nearby female, both hanging on in a once-pristine habitat turned to withered coral beds and ragged remnants of seagrass meadows.
The tropical seas around this jungled island depict, in microcosm, both the seahorse’s threatened state — tens of millions are harvested globally each year — and possible ways to save the iconic species from extinction.
“The seahorse faces an enormous variety of threats,” said Paul Ferber, a British conservationist who has lived on Ach Seh Island for three years, studying the genus Hippocampus and trying to protect its ravaged environment against an armada of illegal trawlers, crab traps and divers in sleek longboats specifically targeting seahorses and related species.
Peering into the darkness one night, Ferber hears the tell-tale chugging of his No. 1 enemy: trawlers from neighboring Vietnam dragging miles-long nets with mesh so fine that even creatures smaller than seahorses can’t escape.
“Big, nasty Vietnamese (boats). It’s either a seine trawler or a pair of them,” he said of vessels that leave behind a lifeless ocean. If equipped with electrified nets, they can even stun and suck in living things burrowed in sea beds.
A powerfully built man with a pair of seahorses tattooed on his chest, Ferber urgently calls his contact in the Cambodian fisheries department, hoping its speedboat can rush from the mainland to arrest the intruders. No luck; the department’s fastest boat was being repaired.
The 39-year-old Ferber, who underwent police training in Britain, said that before such cooperation began, he and his team confronted illegal fishermen alone, armed only with “a slingshot and a bunch of rocks.” He said they were shot at with AK-47 rifles and even a spear gun, and one of their boats was rammed and sunk. Death threats continue.
Seahorses, caught in waters around the world, are sold mainly for Asian traditional medicine.
Amanda Vincent, a Canadian marine biologist and founder of Project Seahorse, estimates that more than 20 million are so consumed each year. Lesser numbers end up as key rings, encased in jewelry or other curios, or in aquariums, with the United States the world’s top buyer for the pet trade. Data from CITES, the international monitor of the wildlife trade, shows that more than 630,000 were imported in the US from 2004 to 2014.
Neither their unique look and behavior (the male, for example, gives birth to the young) nor their place in popular imagination (as charioteers for the Greek god Poseidon, or powerful sea dragons of Chinese myth) seems to have prevented massive exploitation. In Chinese traditional medicine, seahorses ground into powder or dried and eaten whole are believed to cure everything from kidney disease to baldness, despite a lack of scientific evidence. Rice wine with seahorses stuffed inside the bottles is advertised as a powerful sex tonic to “turn a man into an all-night Romeo.”
Visits to Chinese medicine shops in Bangkok and Phnom Penh, Cambodia’s capital, showed brisk sales. In Cambodia, where buying, selling and processing of seahorses is illegal, a dried seahorse was priced at US$2 to US$2.5.
“It’s a race between the conservation ethos and the rape-and-pillage ethos,” said Vincent, who chairs the seahorse expert group of the Switzerland-based International Union for Conservation of Nature. The legal export trade, she says, has been greatly reduced globally, but illegal fishing continues to threaten many of the 41 seahorse species.
Experts are reluctant to make predictions about possible extinctions but agree many populations are in retreat.
“Seahorses are increasing in our area but declining everywhere else,” said Ferber, who discovered the devastation of Southeast Asia’s seas as a dive instructor in Thailand and Cambodia. His group, Marine Conservation Cambodia, is supported chiefly by the International Conservation Fund of Canada.
