Dolphins show the way for fishermen to catch fish

The local fishermen of Laguna, Brazil can know the best time to throw the net, thanks to the help of dolphins.

>>>Freshwater dolphins are about to become extinct

'About 200 local fishermen hand-catch on dolphins. They will not catch without the help of dolphins. Fishermen can recognize the signs of each fish only with their eyes, even naming them, " researcher Fábio Daura-Jorge, Santa Catarina University told LiveScience.

The dolphin provides the signal by wagging its tail for fishermen to throw the net.

However, not all dolphins live in Luguna, but only about 20 children cooperate with fishermen.

According to scientists, dolphins participate in this relationship to catch fish stocks - an important source of food for local fishermen. In order to perform the action, they will swim with the boats of the fishermen. After that, they signaled like wagging their tails to tell fishermen where to drop nets.

Animal experts said that the cooperation with fishermen of dolphins could be inherited from their mother, as the elderly fishermen taught their descendants how to coordinate with fish. The pig finds a livelihood.

The study was published on May 2 in the Biology letters sheet.
