A freshwater dolphin died in the Panguchi River in Bagerhat’s Morelganj upazila on Tuesday.
Fisherman Abdul Hye from the upazila’s Baroikhali village caught the dolphin in his net while fishing in the river. It died just after being brought out of water.
The dolphin was three feet long and 7.3 kg in weight.
After seeing the picture of the dead mammal, wildlife researcher of Wildlife Conservation Society (WCS) Samiul Mohsenin confirmed it was a Ganges river dolphin.
According to the Wildlife (Conservation and Security) Act, the gangetic dolphin is a conserved specie while WSC has listed it as endangered.
Villagers said, on information, local upazila nirbahi officer and fisheries department officials visited the spot.
Morelganj senior fisheries officer Binoy Kumar Roy told Prothom Alo over mobile that freshwater dolphin is often sighted at Panguchi river. The mammal was alive after being caught in net, but it died before their arrival.
Binoy Kumar Roy said the dead dolphin is not very large. Normally, dolphins of this river are large. Gangetic dolphins are globally endangered. However, some mammals are still seen in Bangladesh, India and Nepal, he added.
