Almost 90% of dolphins in the Indian Ocean wiped out by fishing industry, study suggests
A damning new report by an international group of scientists indicates the dolphin population of the Indian Ocean has been decimated, with almost 90 per cent of the animals wiped out by industrial fishing since 1980.
The study suggests this extraordinary extermination is due to the widespread use of huge gillnets used to catch tuna.
Gillnets are walls of netting that are hung in the water column and are either allowed to drift from floating buoys, or can be fixed in one place. They range in size from 100m to more than 30km in length, and operate from less than 5m to more than 20m in depth.
