First record of exotic amur catfish, silurus asotus (Actinopterygii: Siluriformes: Siluridae), in the tibet stretch of the lancang River, China

Abstract

A single specimen of exotic Amur catfish, Silurus asotus Linnaeus, 1758, was captured by gillnet in the Tibet stretch of the Lancang River for the first time. (The Lancang River is an international river and in its lower course is also known as the Mekong River.) It is the first record of this fish species in eastern Tibet. The most possible pathway of the Amur catfish introduction into the Tibet stretch of the Lancang River was a human-mediated release known as life liberation activities or life release ceremony.
