Resumo1. An estimate of the genetic polymorphism and average hetorozygosity in three species of rockfish, Sebastes alutus, S. caurinus, and S. elongatus' was made using differences in electrophoretic mobility of proteins on starch gel. 2. In S. alutus two of twenty-five loci; in S. caurinus, one of twenty-five loci; and in S. elongatus, two of twenty-four loci were polymorphic. 3. This yields estimates of 8,4 and 8 per cent of all polymorphic for the average species population and values of 3·8, 1·8 and 3·3 per cent for the proportion of the genome heterozygous per individual in the average population.
