Why Snakes Are Disappearing From Southeast Asia’s Largest Lake

Cambodia’s Tonle Sap Lake is one of the most biodiverse bodies of water on Earth. Zeb Hogan, a biologist and National Geographic Explorer, is examining how fishing in Tonle Sap is affecting aquatic life. Fish stocks in the lake have dramatically declined over recent decades. Large-scale commercial fishing is regulated by the government, although not effectively. Hundreds of thousands of fishermen operate on the lake. As large, valuable species such as giant catfish disappear from overfishing, fishermen target smaller species.
