Criticality Level Priority
Rationale It is not yet clear if hatchery supplementation provides a lasting demographic benefit to wild populations. Such appraisals require pre- and post-project reference streams, infrastructure to sample juveniles and adults, and genetic analyses to ascertain the pedigree of natural origin fish. Additionally, a suite of factors—including density-dependent effects, location of hatchery releases, habitat conditions, age and size of hatchery adults, spawning locations of hatchery fish, and genetic alterations to hatchery fish caused by domestication—can influence whether a hatchery program will provide a lasting demographic benefit to a natural population. Research is needed to unravel the relative importance of these factors in areas where supplementation has occurred. Results from these studies would help determine the level of supplementation that is appropriate for a subbasin on a species-specific basis. Additionally, in several subbasins hatchery supplementation is being used to reintroduce salmonids into areas where original populations were extirpated. Monitoring and evaluation programs are needed to track the abundance, local adaptation, and straying rates of the reintroduced fish as well as their potential impacts on local biota. This critical uncertainty is from the 2006 Research Plan; see Part 2, ISAB/ISRP 2016-1, CU #3, for a discussion of progress made toward addressing this uncertainty.
