Dolphins of Pakistan nearing extinction "The Indus Dolphin is in danger of extinction because of the extensive irrigation system on the river," Zafar Hashmi, the group coordinator was quoted by IANS news agency as syaing. He said irrigation barrages were preventing dolphins from swimming freely. In addition, farming activity was draining most of the Indus river water, reducing its flow and drying it up in some areas in the winter months. "As a result, the dolphin population has drastically decreased in the last two to three decades," he said. He said the group had contacted several organisations for help. "It is regrettable that our government is doing nothing to preserve these rare fish." Professional fishing tribes are the principal predators for the dolphin. "These people hunt the dolphins for their oil or kill them for meat," he said. Sometimes dolphins get caught accidentally in fishermen's nets and die. The rare specie is called by various names,
including Indus Susu - a local name, Blind River Dolphin and the Side-Swimming
Dolphin. Indus River Dolphins are grey brown in colour, sometimes with a pinkish belly, and measure between 1.5 metres and 2.5 metres in length, weighing a maximum of 90 kg. Breeding takes place in alternate years in shallow water. The reproductive season is from March to May.
STRANGE
MARINE ANIMAL STRANDING IN AFRICA Experts from the West African country's Institute of Oceanographic Research and Fishing visited the scene but were unable to take any samples because of the corpses were so decayed, the government said late Thursday. It was the third June in a row that scores of dead marine mammals suddenly appeared along the country's coast, but authorities voiced concern at the large number of deaths this year. A total of 139 dolphins were among the dead. "A special program is being drawn up and a team of specialists will be on the shore when the phenomenon is at its height to make real-time observations," the Fisheries Ministry said in a statement. It did not say when the observations would begin. A team of scientists from Holland did laboratory tests on samples from corpses beached in the region last year but failed to find any virus responsible for killing the animals. "Nonetheless the Dutch scientists still favor a viral infection as the explanation," the statement said. The waters off Mauritania's barren coast are home to one of the world's largest concentrations of fish, crustaceans and mollusks, as well as hammerhead and tiger sharks, dolphins, turtles, and a dozen species of ray. They are also home to Africa's largest marine park, a 4,500 square mile expanse of ocean which was declared a world heritage site by UNESCO, the U.N. Educational, Scientific and Cultural Organization, in 1989. The impoverished West African country has
taken steps to protect its treasure trove of marine life. Some of its
fishermen agreed a landmark deal to stop fishing shark and ray from the
park earlier this year after Bahamas Wild Dolphin Vacations
