CHATTOGRAM: Another dolphin of endangered species was found dead in the Halda River, the lone natural fish spawning centre of major carp fishes of the country, on Monday.

The dolphin was recovered from Akbaria area under Hathazari upazila in the district in the afternoon.

Halda River Researcher and Coordinator of Chittagong University Halda Research Laboratory Professor Manzoorul Kibria said, “With this, some 33 such dolphins were found dead in the river in the last four years.”

The 15-kilogram dolphin of 36-inch length was buried in Ramdas Munshirhat area in presence of the Upazila Nirbahi Officer, he said. The species is endangered on the list of International Union for Conservation of Nature (IUCN), he added.

Mentionable, the number of freshwater dolphins is decreasing gradually in the river Halda.

A survey revealed existence of a total of 167 dolphins of ‘Platanista Gengetica’ species in the river in 2018.

The number stood at 127 in another survey conducted using technologies two years later in 2020.

The experts attributed to pollutants from the multi-dimensional sources, absence of sewage treatment plant, dumping of household solid and liquid wastages, movement of mechanised boats and dredgers and use of gill-net by the fishermen for the declining dolphin population.

The researchers put emphasis on awareness among the locals and coordination among the agencies concerned including Department of Environment, Fisheries, Forest and local administration for an end to the death of the mammals.
