Banning certain fishing gear can help save world's coral reefs from climate change.Byline: ANI Washington, June 18 (ANI): A new study has suggested that banning or restricting the use of certain types of fishing gear could help the world's coral reefs coral reefs, limestone formations produced by living organisms, found in shallow, tropical marine waters. In most reefs, the predominant organisms are stony corals, colonial cnidarians that secrete an exoskeleton of calcium carbonate (limestone). and their fish populations survive the onslaughts of climate change. The study was carried out by the ARC Centre of Excellence for Coral Reef coral reef Ridge or hummock formed in shallow ocean areas from the external skeletons of corals. The skeleton consists of calcium carbonate (CaCO3), or limestone. A coral reef may grow into a permanent coral island, or it may take one of four principal forms. Studies at James Cook University Situated in the tropical gardens of the campus, the halls of residence provide students with modern social and sporting facilities as well as the opportunity to choose between catered or self-catered accommodation. , the Wildlife Conservation Society, and other groups. The international team of scientists has proposed that bans on fishing gear, like spear guns, fish traps, and beach seine nets, could aid in the recovery of reefs and fish populations hard hit by coral bleaching Coral bleaching refers to the loss of color of corals due to stress-induced expulsion of symbiotic unicellular algae. The corals that form the structure of the great reef ecosystems of tropical seas depend on a symbiotic relationship with photosynthesizing unicellular algae called events. Around the world corals have been dying at alarming rates, due to unusually warm water events resulting from global warming global warming, the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. . Research carried out in Kenya and Papua New Guinea Papua New Guinea (păp` ə, –y has shown that
certain types of gear are more damaging to corals, to coral-dependent
fish and to the key species of fish that are needed to help reefs
recover from bleaching or storm damage.
"This is creating a double jeopardy double jeopardy: see jeopardy. double jeopardy In law, the prosecution of a person for an offense for which he or she already has been prosecuted. In U.S. for both the corals and certain types of reef fish. They are already on the edge because of overfishing- and the additional impact caused by a bleaching can push them over," Dr Cinner explained. The result can be an accelerated decline of the reef, its fish populations - and their ability to sustain local people. "From an ecological perspective, the best response to bleaching is to close reefs to fishing entirely. But that is not feasible everywhere and is a particularly hard sell among the impoverished fishers in developing countries," said co-author Dr. Tim McClanahan of the Wildlife Conservation Society. "In areas where fishery closures are impractical, managers don't have many options and haven't been able to do much but watch the reef die and often not recover," he added. "Selective gear restrictions offer reef managers and fishers alike some middle ground, reducing pressure on the reef and its fish while it is in the recovery phase, while also providing fishers with some options for their livelihood," Dr Cinner said. This middle way is also more likely to be taken up by fishers. "In other research, we've found that fishers themselves prefer gear restrictions to total closures, because most fishers use several types of gear so they can still earn a living when the use of one sort of gear is banned. They are more likely to comply," said Dr Cinner. (ANI) Copyright 2009 Asian News International The Asian News International (ANI) agency provides multimedia news to China and 50 bureaus in India.
