Uncertainties in population dynamics and outcomes of regulations in sockeye salmon (Oncorhynchus nerka) fisheries: implications for management

摘要: Fisheries managers usually have multiple options available but are often unclear on how to choose among them owing uncertainties in biological and management components of fisheries systems. We evaluated the performance current possible future assessment practices for sockeye salmon (Oncorhynchus nerka) British Columbia Alaska by using a computer model that included major their associated (interannual variability recruitment, age-at-maturity, sex ratio, as well uncertainty observations spawner abundances, forecasts outcomes from implementing regulations). One option we was designed make forecasting more realistic accounting long-term trends age-at-maturity. A second reduce deviations between targets actual or “realized” harvest levels. found compared with t...
