| Abstract |
- The application of DNA-based markers toward the task of discriminating among alternate
salmon runs has evolved in accordance with ongoing genomic developments and
increasingly has enabled resolution of which genetic markers associate with important
life-history differences. Accurate and efficient identification of the most likely origin for
salmon encountered during ocean fisheries, or at salvage from fresh water diversion and
monitoring facilities, has far-reaching consequences for improving measures for management,
restoration and conservation. Near-real-time provision of high-resolution identity
information enables prompt response to changes in encounter rates. We thus continue to
develop new tools to provide the greatest statistical power for run identification. As a proof
of concept for genetic identification improvements, we conducted simulation and blind tests
for 623 known-origin Chinook salmon (Oncorhynchus tshawytscha) to compare and contrast
the accuracy of different population sampling baselines and microsatellite loci panels. This
test included 35 microsatellite loci (1266 alleles), some known to be associated with specific
coding regions of functional significance, such as the circadian rhythm cryptochrome
genes, and others not known to be associated with any functional importance. The
identification of fall run with unprecedented accuracy was demonstrated. Overall, the top
performing panel and baseline (HMSC21) were predicted to have a success rate of 98%, but
the blind-test success rate was 84%. Findings for bias or non-bias are discussed to target
primary areas for further research and resolution.
