Threat to otter fishing in Bangladesh

Help

For centuries, fishermen in southern Bangladesh have been fishing in rivers and canals with the help of wild otters which they have trained to drive fish, crabs and prawns towards the net.

The otters have helped thousands of fishermen to survive in this region for many decades, but this rare tradition is in danger as rivers are drying up and the fish population is reducing.
