Conservation Genetics of Pacific Salmon I. Temporal Changes in Allele Frequency

Conservation Genetics of Pacific Salmon I.

Abstract

Recent reductions in the abundance of all Pacific salmon species (Oncorhynchus spp.), coupled with large increases in artificial productioq demand that careful attention be paid to genetic changes occurring in both wild and cultured populations. Analysis of electrophoretic data for chinook salmon (O. tshawytscha) from the Pacific coast of Oregon revealed substantial allele frequency changes over 24 years in hatchery, but not wild populations. Unfortunately, our understanding of the causes of this result is hampered by a lack of theoretical models designed for organisms with life history features like those of Pacific salmon. We used computer simulations to provide a context for understanding genetic changes observed in the hatchery populations.
