Seabird cryptic mortality and risk from fisheries

Debski I, Pierre J (2014) Seabird cryptic mortality and risk from fisheries. South Pacific Regional Fisheries Management Organisation, Honolulu, Hawaii, p 7

The Roadmap for the Scientific Committee (Annex D of the Report on the Second Meeting of the Commission of SPRFMO) requests the Scientific Committee to consider the level of risk to seabird species in a range of trawl fisheries (with reference to discarding of biological material). This paper introduces the concept of seabird cryptic mortality, reviews existing research and illustrates estimation methods that allow for consideration of the full extent of risk that fisheries pose to seabird species through bycatch. While the focus of this paper is on trawl fisheries, longline methods are also covered.
