Large-scale introductions of resident and anadromous salmonids from exogenous sources and urbanization have led to major changes in, and concern for the fate of, indigenous fish populations of the Lake Sammamish/Lake Washington Basin. Specifically, introductions of kokanee (the resident form of Oncorhynchus nerka) from the Lake Whatcom Hatchery and sockeye (the anadromous form of O. nerka) from Baker Lake have caused uncertainty about the ancestry of the kokanee that currently spawn in the…

Distinct genetic isolation between “Kunimasu” (Oncorhynchus kawamurae) and “Himemasu” (O. nerka) in Lake Saiko, Yamanashi Prefecture, Japan, inferred from microsatellite analysis
- Environmental ScienceIchthyological Research
- 2012
A Bayesian-based clustering method separated 144 specimens from Lake Saiko into two genetically distinct groups, corresponding to Kunimasu and Himemasu, resulting in all specimens except two having high probability of purebred.

MOLECULAR GENETIC EVIDENCE FOR PARALLEL LIFE‐HISTORY EVOLUTION WITHIN A PACIFIC SALMON (SOCKEYE SALMON AND KOKANEE, ONCORHYNCHUS NERKA)
- Environmental Science, BiologyEvolution; international journal of organic evolution
- 1996
It is concluded that sockeye salmon and kokanee are para‐ and polyphyletic, respectively, and that the present geographic distribution of the ecotypes results from parallel evolutionary origins of kokAnee from sockeye (divergences between them) thoughout the North Pacific.
Discriminating coho salmon (Oncorhynchus kisutch) populations within the Fraser River, British Columbia, using microsatellite DNA markers
- Environmental Science

Three microsatellite DNA loci were used to examine genetic variation among 16 coho salmon populations within the Fraser River drainage system, in British Columbia, Canada, and show promise as technically simple and highly informative genetic markers for coho Salmon population management.
Biochemical Genetic Comparison of Sockeye Salmon and Kokanee, the Anadromous and Nonanadromous forms of Oncorhynchus nerka

Sympatric sockeye and kokanee were significantly different in all systems examined, demonstrating that genetic differences can persist in the absence of geographic barriers to gene flow.

The pattern of population differentiation of sockeye salmon, as revealed through genetic distance and principal component analyses, resembled a mosaic in that nearest geographic neighbors were not necessarily similar genetically.

It is concluded that divergence has occurred in sympatry and potential isolating mechanisms are examined to confirm that sockeye and kokanee exist as reproductively isolated populations.
