Akkas Ali is a fisherman from Dublar Char, a remote island located off the coast of Bangladesh’s Bagerhat district. He has been fishing in the Bay of Bengal for almost 20 years and has seen several dolphins die there. Most of these deaths were accidental – the dolphins got entangled in fishermen's nets. In the last two years, for instance, three dolphins died after being trapped in Ali's nets.

At least five species of dolphins and several species of whales can be found between the coast of the Sundarbans, the world’s largest mangrove forest, and the Bay of Bengal. The rivers of the mangrove forest are the habitat of Gangetic river dolphins and Irrawady dolphins.

According a 2010 joint survey by the Wildlife Conservation Society and the Bangladesh Cetacean Diversity Project, there were about 225 Gangetic river dolphins, about 6,000 Irrawady dolphins, over 1,000 bottlenose dolphins, and a significant number of Indo-Pacific humpbacked dolphins, pantropical spotted dolphins and spinner dolphins in the rivers and canals of the Sundarbans. Some of these dolphins are also found in the Brahmaputra, Meghna, Karnaphuli and Sangu rivers, which flow from India into Bangladesh.

Just like elsewhere in the world, many dolphins drown in these rivers because they get entangled in fishing gear. This is about to change for Ali, who now wants to become their saviour and plans to help researchers conduct studies on dolphins and other marine aquatic species.

Turning fishermen into conservators

The effort involves two simple things: equipment and training. As fishermen can't monitor their nets, they don't realise when a dolphin gets caught in them. Now they have been issued binoculars, a relatively expensive piece of equipment for them. "Using binoculars, we will be able to see that dolphins are trapped in our nets and can immediately cut the nets so that they can free themselves,” Ali proudly told thethirdpole.net.

Ali is not alone. The Wildlife Conservation Society trained nine fishermen to help in dolphin conservation in April. Fishermen have also been given the equipment necessary for the task, including binoculars, Global Positioning System-enabled devices and cameras to help them monitor dolphin movement in the sea during their fishing excursions.

“By releasing animals from their nets, fisherfolk can save dolphins," Elisabeth Fahrni Mansur, director of Wildlife Conservation Society Bangladesh. "Many do that. But it’s not always that easy, especially because nets are often set at night or are so long that entangled dolphins can’t be detected quickly.”

In the coastal waters, she said, the Wildlife Conservation Society has established a citizen science network among gillnet fishermen who monitor their nets for dolphin entanglements, rescue live dolphins when they become entangled, and collect information and samples from dolphins found dead.

“We provide them with a GPS-enabled device and train them on how to use it to navigate to safety during increasingly frequent extreme storms,” Mansur said. "This has proved to be an effective incentive to engage fishermen in marine megafauna conservation."

A win-win situation

In return, the fishermen are happy to help monitor dolphins in the rivers and the sea. “We generally go to sea for 15-day trips to catch fish,” Ali said. “During that time we will count dolphins and identify their species. We will use GPS to map their movements and take photos.” Hopefully, they will also make short videos of the dolphins as they swim out to sea, he said, keeping a watch on the endangered species throughout the year.

If the fishermen find dead dolphins in the sea, they will collect a piece of their hide. Upon returning home, they will provide the data collected at sea to the researchers.

Jahangir Alam, a senior researcher at the Wildlife Conservation Society, said the role of the fishermen was critical not only in saving the dolphins, but also in aiding research. “We go to sea in the winter to collect data on dolphins, but we cannot do so during the monsoon due to adverse weather," he said. "The fishermen can."

With the help of the data and samples that the fishermen provide, Alam hopes to identify the dolphin species in the region and their habitats. He also hopes that the information will help the Wildlife Conservation Society to map more accurately the risks that the dolphins face as well the trends among the sea mammals.

Steps to save dolphins

This is part of a wider effort in Bangladesh to protect the dolphin population. In 2014, the country declared 1,738 square kilometres in the Bay of Bengal as a marine protected area. Unplanned fishing has been prohibited there and the access of ships to the area has been restricted to ensure a safe habitat for the dolphins.

According to forest department officials, the river dolphins found in the Sundarbans move mostly in the rivers of Andharmanik, Dhangmari, Dudhmukhi, Betmore, Chandpai and Patakata of the Sundarbans East Zone. Therefore, the Bangladesh Forest Department created three dolphin sanctuaries covering 32 square kilometres of the rivers and canals in the mangrove forest in 2012.

“Earlier, we identified three dolphin hotspots in the Sundarbans and have already declared these spots as sanctuaries,” Chief Conservator of Forests Mohammad Yunus Ali told thethirdpole.net.

Still in danger

Although the government of Bangladesh has announced several steps to conserve dolphins, there has been minimal follow-through. Alam, who is also the coordinator of Bangladesh Cetacean Diversity Project, said fishermen are still using banned nets to catch fish in the designated areas and ocean-bound vessels are still using the area as a thoroughfare. According to data collected by the Bangladesh Cetacean Diversity Project, at least 130 dolphins were killed in marine protected areas from January 2007 to April 2016, either because they were trapped in fishing nets or injured by the propellers of ships.

Unchecked fishing continues in the Sundarbans and vessels carrying toxic chemicals move through the rivers. A tanker carrying about 350,000 litres of furnace oil capsized in the Shela River of the Sundarbans, a dolphin habitat, on December 9, 2014 while a cargo ship sank on March 19, 2016.

Three years after the announcement of dolphin sanctuaries, the authorities concerned are yet to finalise a management plan to protect dolphins in the Sundarbans’ rivers. “We have already prepared the management plan and sent it to the Ministry of Environment and Forests. But the ministry is yet to finalise the plan,” Mohammad Yunus Ali said.

Once the plan is finalised, he said, unplanned catching of fish and water vessel movement on the rivers could be checked, which will help ensure safe havens for dolphins.

Akkas Ali is a fisherman from Kachua, Vasha Bazar in the Bagerhat district of Bangladesh. He has been fishing in the Bay of Bengal for almost 20 years and has been a witness to the slaughter of dolphins. Most of these deaths were accidental – the dolphins became entangled in the nets of fishermen, and died. In the last two years three dolphins were killed after being trapped in Akkas Ali’s own fishing nets.

At least five species of dolphins, one species of porpoise and two species of whales are found in the waters between the coast of the Sundarbans, the world’s largest mangrove forest, and Swatch-of-No-Ground, a deep underwater canyon in the Bay of Bengal. The rivers of the mangrove forest are the habitat of Gangetic river dolphins and Irrawaddy dolphins.

According to several surveys conducted between 2002 and 2010 by the Wildlife Conservation Society (WSC) Bangladesh Program and their Bangladesh Cetacean Diversity Project there are about 225 Ganges River dolphins in the Sundarbans waterways. They share these waters with a portion of the population of an estimated 6,000 Irrawaddy dolphins inhabiting Bangladesh’s coastal waters. This is by far the largest population of Irrawaddy dolphins in the world. About 1,400 finless porpoises, over 2,000 bottlenose dolphins and an estimated 620 of Indo-Pacific humpback dolphins, along with pan-tropical spotted dolphins, spinner dolphins, false killer whales and Bryde’s whales are estimated to inhabit Bangladesh’s coastal and deep-sea canyon waters.

Most fisherfolk in Bangladesh do not intentionally harm dolphins. But, just like elsewhere in the world, many dolphins drown because they become entangled in fishing gear. This is about to change for Akkas Ali, as he will now become their saviour, and will even help researchers conduct study on dolphins and other marine aquatic species.
