UncertaintyHow effective is genetic assessment for determining trends in population status and population diversity?
ThemePopulation structure and diversity
SubthemeStatus and trends - assessment
Sources Bitterroot Subbasin Plan
Criticality Level Priority
Rationale The capability to track trends in abundance, harvest rates, and straying in steelhead and Chinook has increased dramatically with the development of Parentage Based Tagging (PBT) and Genetic Stock Identification (GSI) methods based on SNP (single nucleotide polymorphism) panels. Further technical development of SNPs and PBT looks feasible. Already these genetic assessment tools appear to hold much promise for cost-effectively monitoring trends in population status and population diversity in salmon and other species. The Pacific Salmon Commission is currently considering the use of PBT and GSI.
