Incidental catch and its impact on marine mammal populations

Abstract

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
