| Abstract |
Capelin M. villosus from the large oceanic Barents Sea stock and from a local northern Norwegian fjord stock were sampled during 1981 and 1982. Tissue extracts from white skeletal muscle, heart, and liver were analyzed by isoelectric focusing and histochemical enzyme detection. Staining for 11 enzymes revealed at least 20 loci, of which 18 are considered suitable for routine population genetic studies. Tissue distributions, banding patterns, and pI values of the isozymes are described. The frequency of polymorphic loci (P0.99) was 0.22 plus or minus 0.10 and the average heterozygosity per locus (H-L) was 0.008 plus or minus 0.007. Inter-sample differences in allele frequencies at 4 polymorphic loci were not significant and thus did not indicate genetic isolation between the fjord stock and the oceanic stock. |
