Thailand is a world biodiversity hotspot with 176 known snake species. However, anthropogenic influences on snakes associated with growing human populations are poorly understood. Aquatic funnel traps (AFTs) are in widespread use in agricultural areas throughout Thailand, and they have the ability to collect large quantities of by-catch, including snakes. During an on-going study on the human-snake conflict we found, using radio-telemetry, one of our radio-tracked Bungarus candidus (Malayan Krait) individuals dead on 13 October 2015. We had tracked the individual for only 14 days before finding it decapitated 10 m from a villager's house. Upon interviewing the owner, we discovered that the snake had been found dead in a fishing trap, in a man-made irrigation canal located 65 m southeast from his house. Our observation is the first documented case of incidental mortality among upland-dwelling snakes as a result of aquatic trapping in Thailand, and may have implications throughout Southeast Asia. This report suggests fishing traps may be another source of mortality for snakes in human-dominated landscapes, and that further studies may reveal significant rates of terrestrial by-catch in agricultural canals.
