Cyanide fishing, whereby divers crush cyanide tablets into plastic squirt bottles of sea water and puff the solution to stun and capture live coral reef fish, is widely practiced throughout Southeast Asia despite being illegal in most countries of the region. The practice began in the 1960s in the Philippines as a way to capture live reef fish for sale primarily to European and North American aquarium owners--a market now worth some $200 million a year.
But today the technique is also used to supply specialty restaurants in Hong Kong and other large Asian cities. There high roller customers can choose which live fish they want prepared on the spot for their dinner at a cost of up to $300 per plate in what the non-profit World Resources Institute (WRI) calls "an essential status symbol for major celebrations and business occasions." WRI adds that as the East Asian economy has boomed in recent decades, live reef food fish has become a trade worth $1 billion annually.
Of course, the cyanide itself is no good for the fish that ingest it. Internet chat boards are rife with comments about cyanide-caught aquarium fish developing cancer within a year of being purchased. And many aquarium owners are willing to pay a premium for "net-caught" ornamental fish as they have a longer life expectancy.
But perhaps the greater damage inflicted by cyanide fishing is to the coral reefs where it is employed, as cyanide kills the reefs and also many of the life forms that rely on them. Researchers estimate that more than a million kilograms of cyanide have been squirted onto Philippine reefs alone over the last half century. These days the practice is much more widespread, with some of the world's most productive reefs being decimated.
"Despite the fact that cyanide fishing is nominally illegal in virtually...
