摘　　要：由于渔具不同的选择性和多鱼种鱼类共栖 ,人们在对目标种类进行捕捞时 ,不可避免地产生副渔获物及其抛弃。由于渔业资源的下降和人们对海洋环境保护意识的加强 ,副渔获物及其抛弃问题日益成为人们关注的焦点。本文对世界范围内的渔业活动所产生的副渔获物进行分析 ,根据副渔获物的种类、被抛弃情况和原因以及对渔业资源的影响 ,提出了减少副渔获物和抛弃的方法。Because of the selectivity of fishing gear and mixed distribution of fish species, there will be inevitably by-catches and discards when people catch the target species. With the decline of fish stocks and increased conservation of the marine environment, by-catches and discards have become a focus of the public. In this paper the by-catches of the world fisheries are analysed. On the basis of the categories of the by-catches, the reasons of discard and the effects on the fishery resources, the methods of reducing by-catch and discard are proposed.=
