drift net fishing The use of fishing nets of great length and depth, aptly described as "walls of death" because of the huge numbers of marine mammals, birds, and turtles that became ensnared in them. The Tarawa Declaration of 1989 formulated at the 20th South Pacific Forum, aimed at banning drift netting in the South Pacific. In June 1992 the UN banned drift netting in all the world's oceans漂流网捕鱼 (用很长很深的鱼网捕鱼。这种网被形容为"死亡之墙",因为大量的海洋哺乳动物、鸟类和海龟被它们所捕获。 在20世纪"南太平洋论坛"陈述了1989年的《塔拉瓦宣言》,指出禁止使用漂流网在南太平洋捕捞,1992年六月,联合国禁止漂流网在世界海洋范围内使用。)
environmental impact of fishing Fishing may have various negative effects on the environment: effluent and waste from fish farms may damage wild fish, seals, and shellfish. Fish farmers use tiny quantities of highly toxic chemicals to kill lice: one overdose could be devastating. So-called by-catches, or the incidental taking of non-commercial species in drift nets, trawling operations and long line fishing is responsible for the death of large marine animals and one factor in the threatened extinction of some species. Some fishing techniques, like the drift nets, yield not only tons of fish but kill millions of birds, whales and seals and catch millions of fish not intended. Small net holes often capture juvenile fish who never have a chance to reproduce. Some forms of equipment destroy natural habitats, for example bottom trawling may destroy natural reefs. Other destructive techniques are illegal dynamite and cyanide fishing渔业的环境冲击 (渔业对环境有各种负面的影响:从养渔场排放出的废弃物和放流水可能对野生鱼类、海豹和贝类造成危害。养渔业者使用少量高毒性的化学物质来杀死虱子:一旦过量即会造成灾害。使用拖网常捕获非商业性鱼类,其排钩操作和长线捕鱼的方式是造成大型海洋动物和濒临绝种动物死亡的原因之一。有些捕鱼技术,如拖网,不但捕得吨计的鱼获,更杀死数以百万的鸟类、鲸鱼、海豹、和意外捕捉到的鱼类;小小的网孔经常补捉到尚未成长、还未来得及繁殖的幼鱼。 有些设备也破坏了自然栖息地,如拖网的底部可能破坏自然礁石。其他破坏性的技术如非法炸鱼和用氰化物毒鱼。)

fish kill Fish diseases observed in the past three decades and which have been attributed to pollution include: haemorrhages; tumours; fin rot; deformed fins; and missing scales and tails. In industrialized countries, increasing numbers of fish are deemed inedible. Many small kills are not noticed or are not reported, and large kills are often not included because of insufficient information to determine whether the kills were caused by pollution or by natural factors. Low dissolved oxygen levels resulting from excessive sewage is one of the leading causes. The second most common cause is pesticides鱼类死亡 (在过去三十年观察到的鱼类疾病,其中被归于污染引起的:出血;肿瘤;鳍腐烂,变形的鳍,鳞片和尾巴和消失。在工业化国家,越来越多的鱼被认为是不宜食用的。许多小规模鱼类死亡没有被发现或不报导,大规模的鱼类死亡通常没有包含在内,因为缺乏足够的信息判断到底鱼类死亡是由于污染还是由于自然因素。由过度排污造成的溶氧水平低是首要原因。第二大主要原因是农药。)
