Extract

Incidental mortality of Southern Ocean seabirds due to fishing activities well away from the breeding grounds has been implicated in the population declines of wandering albatross (Diomedea exulans) on South Georgia (Croxall and others 1990) and lies Crozet, black-browed albatross (Diomedea melanophris) on lies Kerguelen, and possibly the southern giant petrel (Macronectes giganteus) (Jouventin and Weimerskirch 1990). Albatrosses are particularly at risk from longline fisheries, based on the high proportion in recoveries of banded birds from longline fishing vessels off Brazil (Croxall and Prince 1990), and on direct observation of albatross during surface and midwater longline fishing for tuna in the Tasman Sea (Brothers 1991).
