| Abstract: | Evaluates sub-regions of mitochondrial genome and seven introns in nuclear genome for detecting genetic variation in Dissostichus mawsoni, and for determining stock relationships, using tissue samples from fish caught in waters around South Shetland Islands, Ross Sea, and Indian Ocean sector of Southern Ocean in summer 2001. Dissostichus mawsoni appeared to be characterised by low diversity, and no genetic variation was detected with restriction enzyme digests of nine sub-regions of mitochondrial genome. Polymorphisms were found in four of seven introns digested with the restriction enzymes, but no population differentiation was found among the three sea areas. Direct sequencing of cytochrome b and left domain of control region showed very little variation and no significant genetic differentiation among sea areas. |
