Irrawaddy dolphins live in marine and freshwater of Myanmar. They can be sighted in both coastal areas and Ayeyawady River. The Ayeyawady River is formerly known as Irrawaddy River and the name Irrawaddy Dolphin was taken from this river. 

Castnet Fishing with the Help of Irrawaddy Dolphins

Castnet fishing with the help of Irrawaddy dolphins in upper reaches of the Ayeyawady River is a unique of Myanmar. Dolphins help castnet fishermen by driving fish towards the castnet fishing canoe.  Dolphins and  castnet fishermen communicate by audio and visual signals during the fishing. Only those dolphins lived in Kyaukmyaung and Mandalay segment, about 72km, know tha technique and help castnet fishermen. I studied this fishing in 2004. I submitted my reports to the Wildlife Conservation Society in 2004 and 2005.
