误捕及其对海兽种群的影响

摘要/Abstract

摘要： 几乎在全世界都有误捕海兽的记录.有误捕记录的海兽有鲸目14科62种,鳍脚目3科12种,海牛目2科2种及食肉目1科1种.误捕海兽的渔具包括刺网、拖网、围网、张网、插网和陷阱等.误捕可导致种群数量的下降及生活史特征的改变.我国需要开展这方面的研究工作.

Abstract: Incidental catch of marine mammals is almost occured all over the world.62 species belonging to 14 families of Cetacea,12 species belonging to 3 families of Pinnepedia,2 species belonging to 2 families of Serenia and I species belonging to 1 families of Carnivora are caught incidentally.The fishing gears involved in the incidental catch include gill net,trawl net, surrounding net,stow net and traps,etc.Incidental catch can cause the decline of population number and the change of its life history.A survey on the incidental catch and its impact on the mammal population in Chinese waters should be conducted.

Key words: Marine mammals, Incidental catch, Incidental catch rate, generating mechanism, biodiversity, ecosystem function, ecosystem services, human-involved activity
