Stock structure, uncertainty, and holistic management of Pacific herring fisheries in the Strait of Georgia
Harvest control rules applied to aggregates of individual stocks or life history types can have pronounced small scale effects. Pacific Herring are currently managed as discrete stocks (5 major, 2 minor), and historical analyses of mark-recapture tagging data are consistent with this approach. Spati...
