Starch gel electrophoresis was carried out to survey the genetic variation among species of fish as a foundation for more extensive and detail studies. Variation in average level of genetic variation among taxonomic groups of fish was observed. Estimate for the fish as whole was 0.194±0.023 in the proportion of polymorphic loci and 0.059±0.007 in the mean individual heterozygosity.
The correlation of the proportion of polymorphic loci with the mean individual heterozygosity was observed and the relationship was found to be linear. The calculated regression line was near to the theroretical relationship on the basis of the neutral theory of protein polymorphisms. Thus, it may be concluded that variation in average level of heterozygosity among taxonomic groups of fish reflected difference in effective population size.
