Fishermen reel in shark the size of a school bus

Fishermen in the Pakistani port of Karachi got more than they bargained for Tuesday as they reeled in one of the biggest fish in the sea: a whale shark.

The Express Tribune, a Pakistani newspaper, reported that the 40-foot fish was first spotted ten days ago in seas about 150 km (93 miles) from the city. Mehmood Khan, the owner of a local fishery, said the shark was unconscious at that time and other reports said that it was found dead Tuesday.

A large crowd gathered as a succession of cranes were brought in to lift the shark on to the pier. After several hours and a number of failed attempts, the leviathan was finally brought ashore and promptly sold for 1.7m Rupees ($18,750).

The whale shark was added to the World Conservation Union's list of threatened species in 2008.

The Whale Shark (Rhincodon typus) is a cosmopolitan tropical and warm temperate species and is the world's largest living chondrichthyan (jawed fish with paired fins, paired nares, scales, two-chambered hearts, and skeletons made).

Its life history is poorly understood, but it is known to be highly fecund (capable of producing an abundance of offspring) and to migrate extremely large distances. Populations appear to have been depleted by harpoon fisheries in Southeast Asia and perhaps incidental capture in other fisheries. High value in international trade, a K-selected life history, highly migratory nature and normally low abundance make this species vulnerable to commercial fishing. Dive tourism involving this species has recently developed in a number of locations around the world, demonstrating that it is far more valuable alive than fished.
