Fishermen catch rare Longman's beaked whale off Thatta's coast
Noor Muhammad, a fisherman trained to collect data for tuna fisheries by the World Wide Fund for Nature (WWF) - Pakistan, shared that the specimen was accidently captured and was already dead when it was retrieved from the water. It was too large to be handled and preserved, thus the fisherman used a mechanical lifting device. The male tiger shark was brought to the Karachi Fish Harbour where it was weighed and auctioned for Rs55,000 and converted into finger fish for sale in the market. “Its liver weighed about 150kg and around 120 litres of oil was extracted from it, which will be used to smear the hull of fishing boats to keep them smooth and free from fouling organisms,” he added.

According to Muhammad Moazzam Khan, the technical adviser of marine fisheries at WWF-Pakistan, tiger sharks were once common along the coast of Pakistan. However, he added, shark fisheries almost collapsed due to overfishing. The species is considered ‘near threatened’ according to the International Union for the Conservation of Nature’s red list due to overfishing and a high demand for its meat and fins.
