Researchers Study Unique Dolphin-Fisherman Cooperation in Kerala
Scientists are studying how dolphins in Kerala help fishermen catch more fish by chasing fish towards the shore.
This happens in a lake called Ashtamudi Lake.
Similar things happen in Brazil and Myanmar.
The study will last for 6 years and won't hurt the dolphins.
Scientists launch international research project on dolphin-assisted cast net fishing in Kerala
Study aims to understand ecological and behavioral mechanisms behind cooperation between wild dolphins and traditional fishers in Ashtamudi Lake
