Incidental Capture of Pinnipeds
We reviewed the literature on incidental catches of pinnipeds by commercial fisheries using both passive and active fishing gear. Few incidental catch data were available for most species, although a substantial amount of information has recently become available for species in the North Pacific Oce...

We reviewed the literature on incidental catches of pinnipeds by commercial fisheries using both passive and active fishing gear. Few incidental catch data were available for most species, although a substantial amount of information has recently become available for species in the North Pacific Ocean and the Northwest Atlantic Ocean off Eastern Canada. Incidental catches in passive gear appear to be of sufficient magnitude to have contributed to population declines of northern fur seals (Callorhinus ursinus) and Kuril seals (Phoca vitulina stejnegeri) in the North Pacific and harp seals (P. groenlandica) from the Barents Sea.
