Genetic Methods for Ocean Monitoring and Harvest Management of Pacific Salmon

Pacific Forum – 3:00 p.m.
Pacific salmon undertake extraordinary migrations from fresh water to the ocean and back again. Their well-known ability to return to the waters of their birth leads to predictable population-specific patterns in their distribution, abundance, and migrational timing in fresh water. However, the extent to which population-specific patterns are maintained during the oceanic phase of the salmon life cycle is not well understood. Without such knowledge, management of ocean salmon harvest to minimize impacts on threatened populations while allowing fishing on healthy populations is challenging, and can often be unsuccessful. I will review recent advances in genetic technologies and their application to understanding the ocean distribution of Pacific salmon. I will begin with an overview of the genetic stock identification methodologies in use for decades, and will finish with a description of novel parentage-based tagging methods being developed at our lab.
