- Аннотация: The genetic investigations of different life strategy forms from one of salmon fishes, Kamchatka mykiss (Parasalmo (Onchorhynchus) mykiss) can’t achieves differences between them inside of single population. Possibly, this forms only adaptive and demonstrate range of ontogenetic programs inside of complex salmon species. As we now, the same genotype can formed different phenotypes, according to conditions of environment. The range of these phenotypes within one species also calls as adaptive norms or life strategies of this species (Mednikov 1987). Usually, this strategies can be separate by morphology and physiology, but genetic nature this differences still unknown. The species P. (O.) mykiss have about seven different life strategies. Two of them are mostly separate and have cultivate resident and anadromous forms. This forms clear recognizable according morphometric, scale structure, others parameters. We tried to search genetic differences between them. Resident and anadromous forms from different west and east coast populations of Kamchatka peninsula were investigated by allozyme loci (Pavlov et al., 2000), sites of mitochondrial DNA (Pavlov et al., 2004), different sites of nuclear DNA (Melnikova et al 2010, Semenova et al., 2010). The forms of closely related north american trout’s and cherry salmon (O. masu) were used as a reapers. There are no differences between separate forms inside one population were revealed. It can be supposes that different life strategy forms of Kamchatka mykiss and other salmonides, detect by gene diversity of these species and specific environmental conditions. Thus, there have epigenetic mechanism of adjusting and determine the ways of microevolution species.
