Description
To help assess the biological impact of enhanced salmon on wild stocks, researchers bred a genetic marker into a late-spawning subpopulation of pink salmon in Southeast Alaska in 1979 and 1981. Monitoring between 1983 and 1989 revealed little or no introgression into early spawning subpopulations, and none into populations in a nearby creek. The results of this study suggest that genetic isolation exists between spawning runs separated by time, and that small temporal and spatial (or ecological) differences contribute to population structure. These observations should be considered in taking actions that affect conservation and harvest management or extensive culture of salmonids. Genetica 111:259-267.
