Abstract
Juvenile winter steelhead (Oncorhynchus mykiss) were exercised daily for 1 month before release from Cole Rivers Hatchery. Experimental raceways were drawn down for 1 h each day so that fish were forced to swim at rates of 0.5—3.6 body lengths/s. A control group was not exercised in this manner. Average returns of adults, size of adults, and life histories were not changed by this procedure. Results from this experiment do not support the hypothesis that exercise confers an advantage for survival of juveniles to adulthood.Keywords
