Coho Genetic Stock Identification
The objectives of this project will be to determine the spatial and temporal distribution and total harvest of selected coho salmon stock in Upper Cook Inlet (UCI) commercial salmon fisheries, estimate the total run of selected coho salmon stocks in conjunction with other projects that will estimate coho salmon escapements and determine the spatial and temporal distribution of coho salmon stocks migrating into UCI along the offshore test fishery transect at Anchor Point. If funded this project will provide ADF&G four consecutive years for which we can estimate total coho salmon run and harvest rate for selected stocks, something that has not been possible in the past.
Timeline: June 2016-Spring 2018
Completed sampling of coho salmon captured in the UCI commercial drift and set gillnet fisheries and Southern Offshore Test Fishery in 2016. Completed laboratory analysis of samples selected in proportion to catch and produced preliminary stock composition and harvest estimates for analyzed commercial fishery samples. Determined the spatial and temporal distribution of coho salmon stocks migrating into UCI along offshore test fishery transect at Anchor point in 2016. Draft Report out for review. Unable to estimate total run of selected coho in conjunction with other projects to estimate coho salmon escapements because there was no mark-recapture project to estimate escapement of Susitna mainstem coho salmon in 2016. Will send final draft of report to FWC.
