Abstract: When animals are reared for conservational releases it is paramount to avoid reducing genetic and phenotypic variation over time. Therefore, an understanding of how behavioural and physiological traits affect the performance of an individual both within the captive and the wild environment is required. To preserve threatened populations of salmonids, large numbers of hatchery-raised juveniles are released each year. The captive environment do, however, differ in many aspects from the wild, and t... more
