At least 29 dolphins have died in Halda since September 2017

A gigantic dolphin weighing 120kg was found dead at Chankhali area of Halda River in Chittagong on Tuesday morning.

Confirming the matter to Dhaka Tribune, Hathazari UNO Md Ruhul Amin said upon receiving the news, they quickly rescued the dead dolphin from Chankhali canal, which is connected to the river.

“Later I informed Halda Research Laboratory for a preliminary investigation. As there was no sign of injury in the test, the rescued dolphin was buried in Mekhal Sattarghat area,” he added.

Dr Manjurul Kibria, Halda Research Laboratory coordinator and professor at the zoology department of Chittagong University, said the dolphin was seven and a half feet long.

Since September 2017, 29 dolphins have died in Halda. Most of them had bruises on their bodies, he added.

Kibria also said they examined the dolphin and found no signs of injuries on its body. 

As this was an adult dolphin, it might have died because of its advanced age, he added.

According to the Department of Wildlife Management and Nature Conservation, the dolphins seen in Halda are locally known as Shushuk. These freshwater mammals are mainly Ganges dolphins who usually roam in pollution-free clean water.

About 10 km of the river from Chattar Khal in Raozan upazila of Chittagong to Madunaghat in Hathazari upazila is the main habitat of dolphins.

According to the International Union for Conservation of Nature (IUCN), there are only 1,100 red-listed endangered freshwater dolphins in various rivers around the world.

According to a survey conducted by Halda Research Laboratory, there were 160 dolphins in the Halda. The dolphins are constantly being killed by the mechanical wings of boats and sand dredgers.
