KARACHI - The continuous use of prohibited fishing net by the influential people in the marine water are challenging the writ of the state and also affected the fish stock in Sindh waters, The Nation has learnt. The Sindh fishing industry has reached an edge of destroying. The century-old industry has turned into the alarming situation due to the violation of code of conduct made by the government. The fishermen representative bodies have claimed that the fish stock was 50 per cent eradicated for the last one decade while the exact figure could not be provided due to not conducting the official survey since early 80s. The fishermen bodies termed the use of prohibited nets, deep sea fishing trawlers, toxic waste by the factories and not implementing the law by the authorities concerned as the main reason of fall in fish stock. The fishermen, due to the shortage of fish stock, are moving towards Balochistan but they are facing the difficulties because the Balochistan authorities had strictly implementing their rule and regulation regarding fishing. Talking to The Nation, Sami Memon of Pakistan Fisher folk Forum (PFF) has pointed out that near 250 prohibited nets still set up in all big 17 marine water creeks of the coastal belt of Ibrahim Hydri, Rehri, Sakro, KT Bander, Jati and others by the influential people which resulted in the abolishing of the fish. Such nets were restricted to use for the survival of the fish species but the influential people have not implementing the regulations. Sami said that over-fishing, fishing on commercial basis and neglecting the traditional fishing system had also caused the declining of the fishing stock in Sindh waters. He said that due to changing of the environment across the world, the Sindh waters are also being affected which resulted in dying of a large quantity of fish. He said that no policy to tackle the situation of the climate change had been introduced by the Pakistani authorities so far. The PFF spokesman, while criticising the previous government for issuing the deep sea fishing trawlers, said that that the fishermen of Sindh and Balochistan had been deprived of their rights of livelihood after the government issued the licenses of deep-sea fishing. He said that the growing violation and over-exploitation of large sized deep-sea trawlers had heavily reduced fish stock in Pakistani waters and also causes water pollution and uncontrolled deep-sea fishing had destroyed more than 70 per cent of fish stocks. The fishermen, who had opposed this policy since its inception, have been complaining that foreign trawlers are not only adversely affecting the livelihood of small Pakistani Fishermen but also polluting the sea by throwing excessive small fishes into the sea. According to the official sources in the fisheries department, after reintroducing the deep-sea fishing policy, the federal government started issuing licenses to deep-sea trawlers through set criteria. Previously, such trawlers were allowed to fish between 35 and 200 nautical miles, but in the new fishing policy, the 200 nautical mile-long Exclusive Economic Zone (EEZ) of Pakistan has been divided into three zones. The Zone 1 (up to 12 nautical miles) is reserved for small fishermen, Zone-II (12-35 nautical miles is kept for medium-sized deep-sea trawlers and Zone-III (35-200 nautical miles) for large factory trawlers which are over-exploiting fish resources. Even during the ban of several months, many foreign trawlers have been found fishing in Pakistani waters. These factory trawlers catch millions of tons of fish with up to 3 kilometres lengthy trawler nets, and most of them are harmful to fish species, said the PFF official. He said that trawlers catch hundreds of tons of small or non-commercial fish, which they throw into the sea causing pollution in the coastal waters. Besides creating pollution, these factory trawlers are also adversely affecting the local fishermen as about 70 to 80 per cent of small boats are standing idle, rendering thousands of fishermen jobless, he added.
