Nay Pyi Taw, May 28 (IANS) Dolphins in Myanmar's Ayeyawady river are unique -- they help fishermen by herding fishes towards the net.

The interactive fishing technique between the dolphins and fishermen is simple.

Those who have seen it say the fishermen communicate by audio and visual signals.

Fishing with the help of Irrawaddy dolphins, in the upper reaches of the 2,100-km long Ayeyawady river, is known only to take place in Myanmar.

The fishermen tap on the side of their canoes with a wooden mallet so that dolphins, which get to know about sound by eco-location, are attracted to it, says a descriptive given in myanmarheritagetravel.com

The dolphins show the fishermen which way to turn with their flukes, which is the dolphin tail.

Finally the fluke slap the surface of the water, and the fisherman cast the net exactly at the spot.

The dolphins are a delight to watch.
