Pen Rearing and Imprinting of Fall Chinook Salmon, 1983 Annual Report.

PDF Version Also Available for Download.

Description

Backwaters and protected sites located along the Columbia River between John Day and Priest Rapids dams, and the lower reaches of the Umatilla, Yakima, and Snake rivers were surveyed to determine their suitability for experimental rearing of age-0 fall (upriver bright) chinook salmon. All but eight potential study sites observed were judged as unusable based on criteria which included depth, area, accessibility, potential water level and temperature fluctuations, entrance-access to the river, public use, and obvious water quality problems. These eight sites were then thoroughly evaluated to determine suitability for rearing studies, using water quality and biological data to supplement ... continued below

Description

Backwaters and protected sites located along the Columbia River between John Day and Priest Rapids dams, and the lower reaches of the Umatilla, Yakima, and Snake rivers were surveyed to determine their suitability for experimental rearing of age-0 fall (upriver bright) chinook salmon. All but eight potential study sites observed were judged as unusable based on criteria which included depth, area, accessibility, potential water level and temperature fluctuations, entrance-access to the river, public use, and obvious water quality problems. These eight sites were then thoroughly evaluated to determine suitability for rearing studies, using water quality and biological data to supplement physical observations. The criteria used in the final selection of rearing sites included an assessment of water source, depth, temperature, and quality, proximity to natural spawning sites, ease of adult capture, and benthos and zooplankton abundance. Two sites were selected as satisfying the most criteria for experimental rearing studies: Rock Creek (river km 337) and Social Security Pond (river km 468). All other sites surveyed were ranked as either less desirable, or unusable for these studies.
