Description

At-sea observers are an integral component of commercial king crab (Paralithodes spp.), Tanner crab (Chionoecetes bairdi), and snow crab (C. opilio)fisheries management in the eastern Bering Sea. The Alaska Department of Fish and Game (ADFG) maintains varying levels of observer coverage on crab fishing vessels and processors to aid in achievement of short-term and long-term management objectives. These objectives include in season assessment of fishing performance, general biological knowledge of shellfish, and bycatch for developing harvest strategies and establishing regulatory policy. This paper provides an overview of the high uses of shellfish observer data including the development of models for estimating relative stock abundance, producing preseason projections of fishery performance, and various life cycle and biological applications.
