The overarching goal of this multi-year project is to develop a coho salmon genetic baseline for genetic stock identification (GSI) of Alaska commercial and sport harvest. The ability to account for stock-specific harvest will aid in the development of brood tables and escapement goals for coho salmon in Southeast Alaska (SEAK). This proposal will cover the first two years of intensive field sampling to obtain genetic samples from spawning populations of coho salmon throughout SEAK, focusing on transboundary Taku and Stikine rivers and the Northern Boundary Area. Future proposals will seek funds to genotype these samples and add them to Alaska’s growing coho salmon genetic baseline.
