I visited the largest fresh water lake in Southeast Asia, Tonle Sap near Siem Reap, Cambodi. The lake was flooded when I was there in November and I was able to witness the local fishing culture. While most of what was caught was small minnow sized fish, some people caught and kept a variety of fresh water snakes. Just like the fish, the snakes are eaten by the locals. Later that night, I tried snake soup for dinner. It tasted like fish but was chewier, more leathery and bonier. Would not recommend.
