Evaluating the feasibility of developing biodiversity-based fishery management objectives for Pacific herring

Pacific herring in British Columbia (BC) are diverse in the timing and distribution of their spawning. This diversity contributes to the productivity of fish population and to its resilience, but has yet to be formally included in herring fisheries management. There is evidence that individual herring population groupings consist of genetically distinct sub-populations, and that there is a large population of these groupings, separated by space, consisting of 5 major migratory stocks. Despite consistent application of allowable catch limits in herring fishery, populations in 3 of the 5 major stocks are below safe harvesting levels. This project will use simulation modelling to better understand the structure of the herring stock population, to explore different assumptions about herring biodiversity and to evaluate available management options for conserving biodiversity.
