of this project was to extend existing allozyme data baseline
for Alaskan chinook salmon, contribute these data to the
coastwide chinook salmon database, and evaluate the feasibility
of using these data to determine the origins of chinook
salmon accidentally caught in groundfish trawls. A genetic
analysis was completed on 22 of 47 populations sampled.
Based on heterogeneity and distance analyses, at least
four unique genetic lineages were identified: Southeast
Alaska, Chilkat River, Southcentral Alaska, and Northwest
Alaska. Mixed-stock analysis using genetic data
has been successfully used to identify stock components
of chinook salmon mixtures in Washington and British Columbia
and may be an ideal tool for identifying stock origin
of by-caught chinook salmon in Alaskan waters. The data
collected in this study can be used to accurately identify
the contribution of Alaskan populations in by-catch or
other high seas samples.
