Abstract
We investigated adaptive differences among three geographically separate populations of coho salmon (Oncorhynchus kisutch) by forming first generation intercrosses (hybrid lines) and comparing them to parental types (control lines). Broodstock for the experiment came from the Gastineau Hatchery in Juneau, Hidden Falls Hatchery on Baranof Island, and Neets Bay Hatchery near Ketchikan, Alaska. All were isolated hatchery populations separated by 220–400 km and derived 15–20 years previously from single local wild populations. For each population, gametes were taken from 50 mature salmon of each sex and combined to form nine lines (three control and six hybrid); each line had 50 full-sibling families which were assigned to separate cells of an incubator at Gastineau Hatchery. Embryo survival and development times were measured as indicators of locally adapted fitness traits. Two of the control lines had higher survival rates than hybrid lines formed between either of their parental populations and other populations. Differences (p < 0.05) were found between development times for control and hybrid groups, which varied by as many as 20 days between families and as many as 30 days between control lines. The intermediate expression of development time of intercrossed lines is consistent with additive genetic variation of development time between the ancestral populations of coho salmon and indicates that important genetic divergence exists between the populations. A loss of local adaptation through a change in seasonal timing of completion of embryonic development would occur in intercrosses between the populations.
