5203 |a"In 1993, 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. Both live and carcass mark-recapture studies were conducted to augment the fence count. Total return of adult chinook to the Cowichan River was estimated to be 7,312 in 1993. It was estimated that less than half the spawners made it to the traditional spawning grounds above Skutz Falls. This was probably due to unusually low water levels during the fall. The number of natural spawners was estimated to be 5,047. Fishery Officers estimated the adult chinook escapement to be 5,200. In addition, a water management plan is described which was intended to aid upstream movement of chinook"--Abstract, page vii.
