UncertaintyWhat new harvest and escapement strategies (including selective harvest) can be employed to improve harvest opportunities and ecological benefits within the Columbia River Basin while minimizing negative effects on ESUs (evolutionarily significant units) or populations of concern?
SubthemeImpacts - new strategies, techniques (such as selective fisheries)

Criticality Level Priority
Rationale This question is fundamental to Fish and Wildlife Program’s Appendix D Goal 18: "Enhance harvest of anadromous fish….." and the legal requirement to mitigate for lost fishing opportunities. Harvesting surplus hatchery fish could benefit both people and natural origin populations; opportunities to do so exist when the total spawning escapement exceeds carrying capacity. Some strategies exist for targeting surplus hatchery fish, but further development is needed to address challenges such as catch and release mortality and opposition to marking fish visually and releasing fish that have been captured. Concerns that efficient use of surplus hatchery fish might lead to reduced efforts to restore habitat and improve production of natural populations must be addressed. This critical uncertainty is from the 2006 Research Plan; see Part 2, ISAB/ISRP 2016-1, CU #25, for a discussion of progress made toward addressing this uncertainty.
