Abstract: Starch electrophoresis has shown that the natural populations in the Monterey Bay area of Sebastes atrovirens (Kelp Rockfish) and Sebastes chrysomelas (Black and Yellow Rockfish) vary little within the species in the pattern of enzymes examined. In Sebastes atrovirens two out of six enzymes showed a genetic variation: Glucosephospate Isomerase (Gpi-B) and Isocitrate Dehydrogenase (Idh-A). In S. chrysomelas two rare alleles were found in the Phosphoglucomutase (Pgm-B) locus. Calculations of gene frequencies show that 95.7% of all investigated specimens express identical phenotypes within S. atrovirens and 96.4% within S. chrysomelas were found to be identical in the studied loci.
