| Summary: | Yukon River chum salmon management is difficult because of the need to address a variety of complex issues, such as meeting escapements, while still providing harvest opportunities in a mixed-stock and mixed-species fishery. Management of chum salmon initially relies on pre-season forecasts to decide whether to allow subsistence fishing. Management shifts to in-season assessment as the run progresses, with any adjustments to subsistence fishing schedules made near the first quartile of the run. The goal is to provide fishery managers with data that will assist them in meeting escapement, passage, and harvest allocations to ensure that the fishery is managed in a sustainable and equitable manner. The following objective will be executed to achieve this goal: Estimate the stock compositions of summer and fall chum salmon sampled from the Pilot Station test fishery each year (June 1-September 7). Estimates will be provided for components of the run that can be effectively managed. For summer chum salmon, this ... |
