Abstract
White muscle samples of Antarctic fish (Notothenia rossii, N. neglecta, N. gibberifrons and Chaenocephalus aceratus) were subjected to electrophoretic tests. Isoelectric focusing of general muscle proteins provides a quick method of identifying species. Six muscle enzymes were resolved by horizontal starch gel electrophoresis. These are presumed to be the products of ten independent gene loci. Coefficients of genetic distance were calculated and substantially agree with the conventional taxonomy. Levels of genetic variability are within the normal range for marine teleosts. Two polymorphic enzymes. GPI and PGM, might prove useful as 'genetic tags' for stock identification.
