This book was released on 1995 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1994, the Pacific Biological Station conducted a study of chinook salmon (Oncorhynchus tsawytscha) productivity in the Cowichan River, British Columbia. Major components of this ongoing study include enumeration of spawners, estimation of native food fish catch, recording hatchery broodstock removals, biological sampling, and coded-wire tag data collection. The investigators conducted a carcass mark-recapture study to augment the fence count. This report presents the results of the adult escapement enumeration component of the chinook productivity study. The report also describes a water management plan intended to aid upstream movement of chinook.

This book was released on 1996 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents results of the adult escapement enumeration component of a chinook productivity study conducted on the Cowichan River in fall 1995. Components of the enumeration included recording of salmon counts at 15-minute intervals at a counting fence, estimation of the native food fishery catch, recording of hatchery broodstock removals, collection of biological data and sampling of coded-wire tag recoveries, and carcass mark-recapture studies for both adult and jack chinook. Results presented include total return of adult chinook to the river and an estimate of the total number of natural spawners. In addition, a water management plan is described which was intended to aid upstream movement of chinook.

Available in PDF, EPUB and Kindle. Book excerpt: Presents the findings of part of an ongoing study to assess the productivity of chinook salmon in the Cowichan River, in which researchers began monitoring the downstream migration of chinook juveniles in 1991. They also monitored the interaction between hatchery and naturally-spawned chinook juveniles. Various techniques and equipment such as minnow traps and purse seines were used on the river in 1991 and 1992 to collect information on growth, abundance, and migration timing of juvenile chinook salmon. Results presented include estimates of naturally-spawned chinook juveniles and hatchery releases.
