Chum Stock ID Assessment (Canadian Area 3 Commercial fishery otoliths)

The project is to sample chum releases from the Canadian Area 3 commercial sockeye seine and gillnet fisheries, and analyse the otoliths for Alaskan hatchery otolith thermal marks to determine weekly Alaskan hatchery chum proportion in four subareas of Area 3 in commercial fisheries. The goal is to use the hatchery proportion data to identify chum retention opportunities for the Area 3 commercial fishing fleet while minimizing wild stock chum impacts.
