Description
A small portion of a pink salmon population contributes disproportionately to the next generation, and, as a consequence of year-to-year environmental variation, the more successful portion varies unpredictably from generation to generation. Maintenance of genetic variation is a key to the long-term success of a population, but these studies of inter-broodyear hybrids suggest that outbreeding depression may also occur. The source and nature of genetic variation should be factored into aquaculture and harvest management decisions. Bulletin of the National Research Institute of Aquaculture 1999(Supplement 1):19-26.
