"As part of an ongoing study to assess the productivity of chinook salmon (Onchorhynchus tshawvtscha) in the Cowichan River, the Department of Fisheries and Oceans, Pacific Biological Station, began monitoring the downstream migration of chinook juveniles in 1991. The interaction between hatchery and naturally-spawned chinook juveniles was also monitored. Various techniques and equipment (minnow traps, purse seines, beach seines, incline-plane traps, and auger trap) were used on the Cowichan River in 1991 and 1992 to collect information on growth, abundance and migration timing of juvenile chinook salmon. An estimate of juvenile chinook abundance was not calculated for 1991 since we were investigating various means to collect migrant juveniles. In 1992, the production of naturally-spawned chinook juveniles was estimated to be 810,240 and hatchery releases of chinook juveniles totalled 1.9 million fish. Peak migration for naturally-spawned juveniles occurred from mid-March to mid-April. Hatchery chinook tended to move downstream in a large pulse and most fish appear to be in the estuary within a few days of release"--Abstract, page vii. Includes abstracts in English and French.
