Identification of juvenile fall versus spring chinook salmon migrating through the lower Snake River based on body morphology Identification of juvenile fall versus spring chinook salmon migrating through the lower Snake River based on body morphology
We tested the use of body morphology to distinguish among subyearling fall-run, subyearling spring-run, and yearling spring-run smolts of chinook salmon Oncorhynchus tshawytscha at two lower Snake River dams during the summer emigration. Based on principal-components analysis, subyearling fall-run chinook salmon had smaller heads and eyes, deeper bodies, and shorter caudal peduncles than...

Physiological development and migratory behavior of subyearling fall chinook salmon in the Columbia River Physiological development and migratory behavior of subyearling fall chinook salmon in the Columbia River
We describe the migratory behavior and physiological development of subyearling fall chinook salmon Oncorhynchus tshawytscha migrating through John Day Reservoir on the Columbia River, Washington and Oregon. Fish were freeze-branded and coded-wire-tagged at McNary Dam, Oregon, from 1991 to 1994, to determine travel time to John Day Dam and subsequent adult contribution. Stepwise multiple

Snake River fall chinook salmon Oncorhynchustshawytscha have declined in abundance the last three decades and now managers are seeking methods to restore the population, Estimates of adult fish returning to the Snake River prior to 1957 number in the tens of thousands (Irving and Bjornn 1981), compared to a range of about 300-750 for 1991-1995 (Lavoy 1995). As a result, Snake River fall...
