    Abstract

    Population-genetic structure of Antarctic toothfish (Dissostichus mawsoni) was investigated not once during the last decade and before, but in this work we present our data on DNA-analysis of recent samplings of toothfish from CCAMLR Subareas – 88.1, 58.4.1, 58.4.2 and 48.6. Our findings show difference with publishes data for several genes and present new view onto toothfish population genetic structure. Our results, based on analysis of nuclear genetic markers presented in Kuhn and Gaffney, 2008, do not support genetic differentiation of samples from Ross Dependency. Difference in allelic frequency with previously published data was also found for several loci.
