註釋
The spawning escapement of large (≥660 mm MEF) Chinook salmon Oncorhynchus tshawytscha above the U.S.-Canada border will be estimated yearly from 2019-2021 in the Stikine River, near Wrangell, Alaska. A modified Petersen 2-event mark-recapture project will be conducted using drift gillnets to mark Chinook salmon in the first event, and collection of samples in the Canadian commercial fishery, Little Tahltan River video weir, and on the spawning grounds will serve as the second event. Age, sex and length of both the inriver run and spawning escapement of Chinook salmon will also be estimated. The Alaska Department of Fish and Game and Fisheries and Oceans Canada use these data to make terminal and regional management decisions, and the Pacific Salmon Commission uses the data for coastwide management and stock assessment through the Chinook Technical Committee.
