Dolphins goes extinct day by day

Sundarbans the world’s largest mangrove forest known for its unique flora and fauna. It is very famous for its some globally endangered species, including the Royal Bengal Tiger and the freshwater Ganges and Irrawaddy dolphins.
But now all of them, dolphins are threatened to extinct. Day by day the situation becomes very fragile for dolphins. Overfishing, increasing maritime traffic, poaching, and unplanned tourism is the main reason to hard the situation.
In Sundarbans December 2014, oil spill destroys the vulnerable ecosystem. It very badly affected on the dolphins. Then in 2015 coal-filled ship sinks at the Pashur River. This was a massive environmental disaster for the ecosystem.
During a 2001 survey, Wildlife Conservation Society Bangladesh (WCS) found 225 Ganges dolphins in Sundarbans areas with less salinity, according to ‘Identifying dolphin hotspot in south-eastern Bangladesh’ report. But a survey, conducted between January and April last year, found the number had declined to 159.
Meanwhile, a 2006 survey identified 451 Irrawaddy dolphins in the Sundarbans but another survey in January-April this year found only 198 dolphins of this species remaining. It is raising serious concerns.
The recorded deaths of 108 dolphins – 80 Ganges dolphins, 24 Irrawaddy dolphins, and four Porpoise – in the Sundarbans and adjoining areas from 2007 to 2019 show just how terrible the situation is.
They mainly killed after being caught in the net, hit by trawlers while some were hunted, according to WCS. About a third of these deaths occurred after the dolphins got tangled in fishing nets.
The occurrence of these deaths, despite the presence of three sanctuaries in the Sundarbans, underscores urgent actions to save the mammals.
Madinul Ahsan, a divisional officer of Wildlife Management and Nature Conservation Department Khulna said, “14 Ganges and Irrawaddy dolphins died after being caught in fishing nets in the last six years”.
On July 31, the body of an eight-foot, roughly 120kg Ganges Dolphin was recovered from the Mongla River at Boro Durgapur at Rampal Upazila in Bagerhat.
Mafizur Rahman Chowdhury, a fisheries expert at Khulna divisional Forest Department, said forest officials confirmed that it died after getting stuck in the fishing net.
The mammals need to come up to the surface to breathe. When they are stuck in the net, they are suffocated to death.
Nadim Pervez, coordinator of WCS Education and Livelihood Programme told that “It will be possible to turn the Sundarbans into a safe abode for dolphins through concerted efforts.
The WCS formed a ‘citizen science fishermen safety’ who releases dolphins, tortoises and other endangered species tangled in nets. Dolphins are protected under the Bangladeshi law. They help keep the rivers and sea environment healthy.
“Their declining number is an indicator of falling fish resources. The extinction of dolphins will have a negative impact on the lives and livelihood of people. So, all of us should work together to protect them”, he also said.
