Groups of juvenile spring chinook salmon, Oncorhynchus tshawytscha, reared in 14 experimental raceways at Willamette Hatchery, Oregon, showed bimodal distributions of lengths before their release from the hatchery. Estimates of lengths of juveniles a

Wild juvenile coho salmon (Oncorhynchus kisutch) were captured in traps or by seining during the course of parr–smolt transformation and migration from a small coastal stream in Oregon. Physiological measurements indicated that gill (Na+K)-ATPase s

Rainbow trout allowed to undergo volitional release at Roaring River Hatchery, Oregon, were separated into migrant and non-migrant populations. In two of the three years of the study, the extent of migration from the raceway was similar to the extent
