Northern Boundary Coho Salmon Genetic Baseline Augmentation

We propose to initiate a multi-phase approach to completing the genetic baseline for Northern Boundary coho salmon (“coho”) populations. Our primary objective is to augment the current baseline so that managers can reliably estimate stock composition of coho populations susceptible to harvest in Canadian and Alaskan mixed-stock fisheries. Augmenting the number of coho populations in the SNP baseline will increase genetic resolution, allowing us to identify the populations of origin with higher precision for coho captured in mixed-stock fisheries in Canada and the U.S. When used in conjunction with abundance estimates of a specific coho population, an upgraded genetic baseline can also improve estimates of exploitation rates in mixed-stock fisheries and therefore further support informed management decisions.
