Description:

The stock composition estimates for Chinook salmon bycatch samples collected from federally managed trawl fisheries in the GOA continue to show that the vast majority of Chinook salmon that are encountered originate from three stock groups that are located South and East of the Alaska Peninsula. This pattern is consistent for samples analyzed across finer-scale area and time strata within the GOA.
