520 | |aThe status of the Queen Charlotte Sound (5AB) population of Pacific Cod (Gadus macrocephalus) was assessed using a delay difference model. Despite large uncertainty, biomass and recruitment are estimated to have been below the historical average since the mid-1990s, and biomass is currently estimated to be below the median biomass minimum in 1985. Model estimates of biomass and stock status were very sensitive to prior assumptions about natural mortality, variance in the mean weight data, and the goodness of fit to the indices of abundance, particularly the commercial CPUE data. There is considerable concern that the 5AB fishery switched from a directed fishery to an avoidance fishery after the implementation of Individual Vessel Quotas in 1997, and the influence that this has had on the model’s interpretation of catch and CPUE data. |
