NEW SCIENTIST (London, UK) Issue 2611 07 July 07 The world's largest snake hunt
Seven million: that's the estimated annual toll in the world's largest snake harvest, currently taking place on Tonlé Sap in Cambodia - the largest freshwater lake in south-east Asia.
"I don't know of any other reptile that is exploited to this extent," says Sharon Brooks, a graduate student at the University of East Anglia in Norwich, UK, who described her studies of the hunt this week at the Society for Conservation Biology's meeting in Port Elizabeth, South Africa.
Tonlé Sap's water snakes were largely undisturbed until about two decades ago, when declining fish catches and demand for meat for local crocodile farms left Tonlé Sap's desperately poor fishermen with little choice but to set their nets for the snakes. Crocodile farming has surged in Cambodia since the country opened up to international trade. Local farms raise hatchlings which are then exported to Thailand and Vietnam, where they are grown for their skins.
The hunt is seasonal, reaching a peak in the monsoon from June to December. As the wet season progresses, the river draining the lake reverses its flow, causing Tonlé Sap's area to expand fourfold or more. About 70 per cent of the snakes caught are rainbow water snakes (Enhydris enhydris). While the total population size is unknown, Brooks believes the current harvest is unsustainable.
Banning the hunt is impractical, given that it is so vital to the local economy. "These people don't have room to manoeuvre," says Brooks. She suggests instead that suspending the hunt during the breeding season in November and December would help.

This is what always makes me wonder why more Homalopsinae snakes are not imported. Generally they are Not rare in their native lands. In some places---they are a nuisance.....
