Effects on fitness traits of intercrossing three geographically separate populations of southeast Alaska coho salmon (Oncorhynchus kisutch)

Thesis (M.S.) University of Alaska Fairbanks, 2002Adaptive differences among three geographically separate populations of coho salmon (Oncorhynchus kisutch) were investigated by forming first generation intercrosses (hybrid lines) and comparing them to parental types (control lines). Survival, development time, size at ponding, and first year growth were measured as indicators of locally adapted fitness traits. Significant differences (p
