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.

Book excerpt: In 1996, the Dept. of Fisheries and Oceans, Pacific Biological Station undertook a study of juvenile chinook salmon (Oncorhyncus tshawytscha) productivity in the Cowichan River. This report presents the results of the juvenile chinook production study, which includes timing of the chinook fry migration, estimates of the abundance of naturally reared chinook, juvenile chinook growth rates, and the interaction between hatchery produced and naturally reared chinook juveniles. Incidental catches of other species were also recorded.

Available in PDF, EPUB and Kindle. Book excerpt: During 2000-02, a study of juvenile chinook salmon productivity in the Nanaimo River, Vancouver Island, was carried out and results are presented in this report. Three key elements of the study are: enumeration of juvenile out-migrants, monitoring growth of hatchery- & naturally-reared fry, and monitoring hatchery releases and interaction between hatchery- & naturally-reared fry in the river. A rotary screw trap was used to estimate fry production. Recapture results of marked fry that were released above the trap site were used to expand trap catches to estimate total production. Separate results are presented for each of the three years of the study, including information on biophysical conditions in the river, migration timing, daytime versus night-time migration, trap efficiencies, abundance, egg to fry survival, and juvenile chinook growth.

This book was released on 1977 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Between April 7 and July 2, 1975, coho salmon (Oncorhynchus kisutch) and chinook salmon (O. tshwaytscha) smolts from the Cowichan River system were captured and tagged with binary coded-wire-tags. This was a pilot study to assess logistics and field methods of tagging sufficient numbers of juveniles from a wild stock, at a reasonable cost, for assessment of ocean migration patterns and fishery contributions.
