Genetic Diversity in a Small Population of Sockeye Salmon Oncorhynchus nerkaWalbaum from the Ola River (the Northern Coast of the Okhotsk Sea)

Genetic Diversity in a Small Population of Sockeye Salmon Oncorhynchus nerkaWalbaum from the Ola... The genetic structure of a small sockeye salmon population from the Ola River (Tauyskaya Inlet, the Okhotsk Sea) was shown to exhibit high heterogeneity. Significant differences of LDH-B2*and ALAT-2*gene frequencies were detected not only among samples within the spawner and juvenile groups but also between spawners and juveniles as a whole. The average heterozygosity of sockeye salmon from the Ola River was considerably lower than the corresponding values for other Asian populations. The Ola sockeye salmon is genetically similar to the population from the Pakhach River of the northwestern Kamchatka Peninsula but different from other Kamchatka populations and the Okhota River population. A hypothesis explaining the genetic differentiation of Asian sockeye populations is advanced. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The genetic structure of a small sockeye salmon population from the Ola River (Tauyskaya Inlet, the Okhotsk Sea) was shown to exhibit high heterogeneity. Significant differences of LDH-B2*and ALAT-2*gene frequencies were detected not only among samples within the spawner and juvenile groups but also between spawners and juveniles as a whole. The average heterozygosity of sockeye salmon from the Ola River was considerably lower than the corresponding values for other Asian populations. The Ola sockeye salmon is genetically similar to the population from the Pakhach River of the northwestern Kamchatka Peninsula but different from other Kamchatka populations and the Okhota River population. A hypothesis explaining the genetic differentiation of Asian sockeye populations is advanced.
