Impacts of the Columbia River hydroelectric system on main-stem habitats of fall chinook salmon Impacts of the Columbia River hydroelectric system on main-stem habitats of fall chinook salmon

Salmonid habitats in main-stem reaches of the Columbia and Snake rivers have changed dramatically during the past 60 years because of hydroelectric development and operation. Only about 13% and 58% of riverine habitats in the Columbia and Snake rivers, respectively, remain. Most riverine habitat is found in the upper Snake River; however, it is upstream of Hells Canyon Dam and not...

Identification of a genetic marker that discriminates ocean-type and stream-type chinook salmon in the Columbia River basin Identification of a genetic marker that discriminates ocean-type and stream-type chinook salmon in the Columbia River basin

A marker based on randomly amplified polymorphic DNA (RAPD), OT-38, was discovered that nonlethally discriminates between stream-type and ocean-type populations of chinook salmon Oncorhynchus tshawytscha in the Columbia River basin, including the threatened fall-run (ocean-type) and spring-run (stream-type) Snake River populations. This marker was developed by amplifying chinook salmon...

Relationships between metabolic rate, muscle electromyograms and swim performance of adult chinook salmon Relationships between metabolic rate, muscle electromyograms and swim performance of adult chinook salmon

Oxygen consumption rates of adult spring chinook salmon Oncorhynchus tshawytscha increased with swim speed and, depending on temperature and fish mass, ranged from 609 mg O2 h-1 at 30 cm s-1 (c. 0.5 BLs-1) to 3347 mg O2 h-1 at 170 cm s -1 (c. 2.3 BLs-1). Corrected for fish mass, these values ranged from 122 to 670 mg O2 kg-1 h-1, and were similar to other Oncorhynchus species. At all...

Epizootiology and histopathology of Parvicapsula sp. in coho salmon Oncorhynchus kisutch Epizootiology and histopathology of Parvicapsula sp. in coho salmon Oncorhynchus kisutch

The epizootiology and histopathology of the myxosporean Parvicapsula sp. was studied during monthly health surveys of 4 groups of coho salmon Oncorhynchus kisutch at a commercial farm in Puget Sound, Washington, USA, from 1984 to 1986. No Parvicapsula sp. was detected in histological samples taken from juvenile fish in fresh water, but the parasite was detected in fish from all groups 2...
