UncertaintyWhat is the relationship between basinwide hatchery production and the survival, fitness, and growth of naturally produced fish in freshwater, estuarine, and ocean habitats?
ThemeFish propagation
SubthemeBasinwide demographic effects

Criticality Level Priority
Rationale Greater knowledge of the various ways in which hatchery fish interact, both directly and indirectly, with natural origin fish is needed to evaluate the cumulative effects of fish releases from the Basin’s hatcheries. Prospective management actions designed to lessen the cumulative impacts of hatchery fish become possible once the locations, life stages, types of impacts and their potential consequences have been identified. For example, the goals and size of supplementation programs could be regulated by estimating juvenile and adult carrying capacities in the subbasins where hatchery fish occur. It is unclear, however, if density-dependent considerations have been used or will be used to guide supplementation efforts in the Basin. Uncertainties also exist about the ability of segregated or integrated hatchery programs to meet adult production and harvest goals. This critical uncertainty is from the 2006 Research Plan; see Part 2, ISAB/ISRP 2016-1, CU #6, for a discussion of progress made toward addressing this uncertainty.
