Irrawaddy dolphin is very intelligent like all the dolphins, he looks like beluga but is more close to the killer whale. It is very nice, and he collaborates with fisherman helping them to fish.
They live in the estuaries of big rivers. It can be found even in not deep water in some bays. This dolphin has great importance even for the population. He is considered a sacred animal by some communities like the Khmer and Lao. But he can stay not only in the salted water. A small population lives even along the Mekong River in fresh water.
The major risk is that share the same habitat with humans. So he is in conflict with human activity. According to IUCN, the local fisherman confirm that major responsible for dolphin deaths is the entanglement in large-mesh. In Cambodia, responsible for decline it is the technique of fishing used. Unfortunately, in this country during the war, the locals discovered the effect of the bomb in the water.
So they start to use explosives for fishing. The problem of this deprecate, and forbidden technique is the devastation of the ecosystem. Indeed with the explosion, all the part of ecosystem included vegetables are invested by the shock wave. With explosion you don’t kill your prey only, you’ll kill all the fish and dolphins in the explosion affected area.
