Estimates of the historic run and escapement for the Chinook salmon stock returning to the Kuskokwim River, 1976-2011.

Alaska Department of Fish and Game, Fishery Data Series No. 12-49, Anchorage.

Total run of Chinook salmon (Oncorhynchus tshawytscha) to the Kuskokwim River from 1976 through 2011 was estimated using a model developed for data-limited situations. The model simultaneously combined information on subsistence harvest, commercial harvest and effort, sport harvest, test fish harvest and catch per unit of effort at Bethel, mark–recapture estimates of inriver abundance, and counts of salmon at 6 weirs and peak aerial counts from 14 drainages all spread throughout the Kuskokwim River drainage. The estimates of historic run size were then combined with available information on the age structure of the stock to reconstruct the total return by age and ultimately estimate a brood table.
