The fishermen of Sukkur have thrown overboard all human norms and business ethics in their quest for an easy catch. Out on the banks of River Indus near Sukkur Barrage, carcasses of turtles and other marine species can be found lying like pebbles on the beach, died not of some mysterious disease but ravenous greed of some local fishermen. These merchants of death throw some poisonous chemical in water to kill the fish, as well as a host of other marine life just because they do not wish to struggle with their nets. The dead marine life immediately floats on to the surface of river. The (poisoned) dead fish from among this dead float is carried to the local market for sale leaving behind other species to be consumed by dogs and vultures on the river bank. It appear that either the local officials of district administration, police and irrigation are mixed-up in this dirty business or do not care a damn about the marine life and health of people of their precinct who are consuming this poisonous fish on regular basis. Those involved in this heinous trade are apparently desensitized to the serious harm they are causing to ecology and humanity of Sindh. The marine life being depleted in this outrage include the Indus Dolphin, a rare mammal species protected under the Dolphin Conservation Project of World Wild Life Organization. I wonder if the CM Sindh knows or cares at all? -R. A SIDDIQUI, Sukkur, March 31.
