Genetic stock identification of sockeye and chum salmon from Bristol Bay, alaska. Final report
Abstract
To study the Pacific salmon that may be affected by oil and gas development in the North Aleutian Basin, Alaska, electrophoretic methods of protein separation were used to genetically characterize stocks. In 1987, tissue samples were collected from eleven populations of sockeye salmon and four populations of chum salmon from Bristol Bay drainages. In the laboratory, 50 gene loci from each collection were analyzed to establish genetic baseline data. In comparisons to sockeye salmon sampled from the same drainages in previous years, no significant differences in allele frequencies were found. The genetic identities (Nei) amoung Bristol Bay sockeye salmon populations are high. Few loci are variable, and only 2% of the total genetic variation is due to differences between populations. Bristol Bay chum salmon sampled have genetic identities of 0.97 or more. Divergence between chum stocks, at 4%, is twice that of sockeye salmon sampled. Computer simuations with maximum-likelihood statistics and re-sampling procedures were used to estimate the composition of artificial mixed stocks made up from baseline data.
