Indus Blind Dolphin faces the threat of ‘genocide’ because Indus River faces record water shortage

Indus Blind Dolphin, a protected species, is fighting a war of survival in the Indus River because of record water shortage. The required water level in the reserve stretch of 210 kilometres for blind dolphin is at least 40 thousand cusecs. Only 10 to 15 thousand cusecs of water is currently available which makes breeding extremely difficult for the world renowned Indus Blind Dolphin.

It was after a research of about 40 years that the wildlife department found these dolphins between the Indus River’s Guddu and Sukkur Barrage area. At present there are 602 dolphins surviving in this stretch of the River Indus, declared as Indus Dolphin Reserve by the Sindh Wildlife Department way back in 1974. There is an Indus Dolphin Centre, established for its monitoring and safety, by the same department a few years ago.

Unfortunately, the authorities of Wildlife, Irrigation and IRSA have not made any more efforts to make the Indus Blind Dolphin (Andhi Bulhan) secure.

The Indus Blind Dolphin (Platanista minor) is one of the world’s rarest mammals and the second most endangered freshwater river dolphin. Endemic only to Pakistan, it is a close relative of Platanista Gangatica, which is found in India in the Brahmaputra and Ganga rivers. Historically, the Indus Blind Dolphin was found in abundance in the Indus River and its tributaries, mainly from the Himalayanfoothills (NWFP) to the delta region (Sindh) about a century ago. Its range was approximately 3,500 km of Indus River from upstream Attock to downstream delta region and the Sutlej, Ravi, Chenab and Jhelum rivers. At present, the potentially available habitat has shrunk to less than 900 km — mainly between Jinnah to Sukkur barrage.

Actually, the construction of dams and barrages on the Indus River has changed the distribution and movement of the Indus Dolphin and divided its current population into four or five subpopulations that exist in isolated pockets between these barrages and dams. The centre of abundance for the Indus Dolphin is currently in the area of Sindh.

Originally Platanista Indi was an inhabitant of the sea when the vast Indian subcontinent was submerged under the Tethys sea during the Eocene geological period. But as the land level rose and the sea dried up, the dolphins headed to adapt themselves to the new habitat provided by the turbid waters of the river. Adapting to the vastly changed environment cost them the loss of their sight. However, nature compensated the animal with the development of a perfect echolocation or sonar system. Thus, dolphins are able to navigate in the fierce current, find food and identify objects in the turbid waters of the river.

In view of the acute scarcity of water in the reserve area in Indus River and the consequent danger to the protected genus, TNS spoke to the Deputy conservator Wildlife Sukkur region Hussein Bux Bhaagat. “The water level in Indus River has been going down since 2005 and we are aware that Indus Blind Dolphin cannot survive in low level of water. Therefore I made many correspondences with the authorities of IRSA and irrigation departments but there is no response.” Bhaagat told that Indus Blind Dolphins can swim actively only when the water level is high and move freely up and down through the water currents in search of food .He appealed to the authorities of irrigation and IRSA to not create water shortage in Indus Dolphin Reserve between Guddu and Sukkur Barrages to save the species.

An environmentalist Nasir Ali Panhwar from IUCN told TNS that Indus Blind Dolphin is a typical fresh water mammal. The body is smooth, hairless, fish-shaped and pinkish gray in colour. The skin is devoid of mucous secretions and so delicate that it can be easily cut with a slight touch. He added that Dolphin has broad flippers and a long slender beak, which is comparatively shorter in the male than in the females. A fully grown, mature animal weighs between 100-120 kg and has a body length of about 170-176 cm and new born dolphins weighs 2-3kg and are 30-36cm in length. The animal breathes through a blow-hole located on the top of the head, which is directly connected to the lungs. Though virtually blind dolphin locates and identifies objects and prey by using a well-developed sonar system.

These animals prefer to live in groups near anchored boats and at the mouths of rivers and inundated canals. But the chances of fish disturbance are much more due to the frequent movements of boats. Nasir Panhwar explained that there are about //17 dolphin shoals between Guddu and Sukkur barrages. “Dolphins don’t stay permanently at a particular place but move from one place to another in search of food. At night, the dolphins come close to the fishing nets and boats to catch small fish, while during the day they prefer to stay at a distance from the boats because of human activity.”

He also told that Dolphins spend little time sleeping and mostly keep on the move in search of food. Adults surface every one to three minutes and calves 30-45 seconds to breathe through the blow-whole.

About the reproduction of Indus Blind Dolphins another environmentalist Amar Gurirro told TNS that the gestation period is about 11-12 months. After mating in April and May, breeding takes place in April-May in of the following year. He explained that Dolphins give birth to calves in shallow water no deeper than 0.5-1.5 meters, where water current is gentle. It is an observation by the experts that the birth process is rapid and the baby slips easily through the birth canal, tail first. The entire birth process takes place under the water. As soon as the baby is born, the mother quickly escorts the calf to the water surface to breathe deeply for the first time in air. The mother supports her baby with their flipper for about one and a half month and then releases the baby for the independent life like other baby dolphins.

Amar Gurirro told TNS that the Indus Blind Dolphin swims very fast to catch live fish. It holds the fish in its jaws at a right-angle to the beak, and swallows the whole fish, head first. During April and May when breeding takes place, dolphins are seen in shallow water. It is obvious that the mother dolphins easily find their prey by taking refuge in brush wood and other growth to feed their babies and themselves.

About the Dolphin a local fisherman Abdullah Mallah said while talking to TNS: “We used to catch fish in Indus River on a regular basis for many years. During this period we used to see dolphins in Indus River here in Sukkur barrage. He told that once a dolphin was caught in the net. When we saw, it was already dead. At that moment we were very disturbed because it was bad omen. I and my cousin Ali Sher also a fisherman buried the body of dolphin in the open land quite far from our homes.”

About the capture of dolphins by fishermen, the deputy conservator Hussain Bux Bhaagat told TNS that fishermen are illiterate so they don’t know about the significance of dolphins world wide. “We have charged such fishermen with fines etc and such incidents have not happened in recent times. We have extend the security system in Dolphin reserve zone.”

  1. we can still protect them if we make a proper plan.We can stop polluting the water and fishing…so we can ptotect the remaining ones by stopping these things
    it can really be helpful..

  2. Its so funny na! when i see all this environment and echo activistis to save different kind of flora and fauna, but no one talk for the basic right of living in this world for humans… what is happining in iraq, plastine, afghanistan. …. can any body talk of it …?

  3. we all people around the world, should get united and to do some work …how to save our precious gift given by ALLAH???

    lets open up our eyes and though its our duty to save………

  4. we have to work together for saving these beautiful and innocent mammals.
