Large-scale human consumption putting the world’s largest amphibian at risk

The world’s largest amphibians, giant Chinese salamanders, were once thought to be widespread but now face imminent extinction due to illegal poaching and hunting as a luxury food, researchers said on Monday.

“The overexploitation of these incredible animals for human consumption has had a catastrophic effect on their numbers in the wild over an amazingly short time span,” said co-author Samuel Turvey, a researcher at the Zoological Society of London.

“Unless coordinated conservation measures are put in place as a matter of urgency, the future of the world’s largest amphibian is in serious jeopardy.”

Vast surveys were conducted in 2013 and 2016 at river sites where the critically endangered salamanders — the size of small alligators and weighing some 64 kg — are known to live. “We cannot confirm survival of wild Chinese giant salamander populations at any survey sites, and consider the species to be extremely depleted or functionally extinct across the huge surveyed area,” said the report in the journal Current Biology.

China has a programme in place to breed and release giant salamanders back into the wild. At the few sites where salamanders were seen, researchers could not confirm whether they were wild or farmed. “Our field surveys and interviews indicate the species has experienced catastrophic range-wide decline apparently driven by overexploitation,” said the report.

“The status of wild populations may be even worse than our data suggest. Conservation strategies for the salamander require urgent updating,” said Jing Che from the Kunming Institute of Zoology.
