Project Details

This research provided a means of evaluating the success of rehabilitation programs by elucidating the proportional contribution of various hatchery stocks to adult recruitment onto spawing reefs and to natural reproduction. Researchers identified the reproductive success of reintroduced lake trout from different hatchery strains. Identification of the relative contribution of each of several introduced hatchery strains allowed researchers to match putative donor strains to specific reef habitats based on differences in strain fitness, thus eliminating redundant and wasteful production.
