UncertaintyHow can fishery interceptions and harvests of ESUs or populations, both hatchery and wild, best be managed to minimize the effects of harvest on the abundance, productivity, and viability of those ESUs and populations?

Criticality Level Priority
Rationale Most fisheries in the ocean and in the Columbia River mainstem harvest salmonids from a variety of populations and hatcheries. Better information is needed on the stock composition of fish in mixed-stock fisheries both within and outside the Basin to manage and evaluate harvest impacts on natural-origin populations. Newly emerging tools could improve the accuracy and the cost effectiveness of stock identification. The information can be used adaptively by managers to achieve harvest rates (range) needed to sustain productive fish populations and fish harvests in the future (see Biological Goal above for identification of sustainable harvest rates). This critical uncertainty is derived from the 2006 Research Plan; see Part 2, ISAB/ISRP 2016-1, CU #24, for a discussion of progress made toward addressing this uncertainty.
