"In 1995, the Biological Sciences Branch, 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, ii) estimation of native food fish catch, iii) recording hatchery broodstock removals, iv) biological sampling and coded-wire tag (CWT) 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 16,134 in 1995. The number of natural spawners was estimated to be 13,452. In addition, a water management plan is described which was intended to aid upstream movement of chinook"--Abstract, page vi.
