The population of critically endangered
Mekong River Dolphins or its also called Irrawaddy Dolphins in the
Cheuteal trans, boundary pool between southern Laos and northern Cambodia
has shrunk by 50% this year alone and the population is
functionally extinct in Laos, according to WWF.
Irrawaddy dolphins can be found in some coastal areas in Asia but there
are only three freshwater subpopulations, in the Ayeyarwady River in
Myanmar, the Mahakam River in Indonesia, and the Mekong River in
Cambodia and the Lao PDR.
The use of gill nets, especially unmanned gill nets, is thought to
be one of the main reasons for the demise of the dolphins. Gill nets are
vertical panels of netting set in a straight line across a river to
catch fish. Being large aquatic mammals, Mekong River dolphins, as well
as other endangered aquatic species, are often caught in gill nets,
and drown as a consequence.
