Description:"The Winter Run Harvest Model (WRHM) forecasts the annual age-3 ocean impact rate on Sacramento River winter Chinook resulting from salmon fisheries south of Point Arena, California. This impact rate includes both landed and non-landed mortality attributable to fisheries. The model is a tool developed for use in the Pacific Fishery Management Council (PFMC) arena for managing fisheries to comply with the National Marine Fisheries Service Endangered Species Act consultation standard for Sacramento River winter Chinook beginning in 2012. Analogous to other models used for assessment and management of salmon through the PFMC process, the WRHM is temporally and spatially stratified. Impact rates are forecast for each month, area, and sector (commercial, recreational) to capture variation in exploitation patterns and fishery management measures that occur at that scale. A forecast of the total age-3 impact rate is then made by aggregating impacts over all strata where fishing occurred. The WRHM is capable of accounting for the customary fishery management measures used by the PFMC (e.g., time/area/sector closures, quotas, and minimum size limits) and therefore readily integrates into the annual PFMC salmon fishery planning process"--Abstract.
