This project conducts pre- and post-commercial fishery Dungeness crab (Cancer magister) surveys in Crab Management Areas I (Fraser River delta) and J (Boundary Bay) to continue the long-term historic record of crab Catch Per Unit Effort (CPUE). The survey also collects data on population structure between years by documenting variability in moult times, breeding times, egg extrusion and release, mortality rates, and provides an accurate record of trap bycatch. These surveys have been used to investigate the effects of soak duration, bait and trap type, escape port efficiency, and provide tissue samples for toxicological and genetic analyses. |
