Adult chinook escapement assessment conducted on the Cowichan River during 1998 / D.A. Nagtegaal and E.W. Carter.Fs97-4/2501E-PDF

"In 1998, the Stock Assessment Division, Pacific Biological Station, conducted a study of chinook salmon (Oncorhynchus tshawytscha) productivity in the Cowichan River. Major components of this ongoing study include: i) enumeration of spawners and total return, ii) estimation of Native food fish catch, iii) recording hatchery broodstock removals, iv) biological sampling and coded-wire tag (CWT) recovery data collection. A carcass mark-recapture study was conducted to augment the fence count. Total return of adult chinook to the Cowichan River was estimated to be 7,062 in 1998. The number of natural spawners was estimated to be 4,328. Carcass mark-recapture escapement estimate was determined to be 2,087 (95% CL; 1,956 - 2,218)"--Abstract, page vi.
