説明

Variation of 11 enzymes and the muscle protein presumably controlled by 19 loci was analyzed by electrophoresis in 506 individuals of Ayu, Plecoglossus altivelis, from 9 natural populations. Six loci (32%) were polymorphic in one or more populations. The number of alleles per locus in the average population was 1.13. The average proportion of polymorphic loci and the average heterozygosity were 9.1% and 0.6%, respectively. These estimates of genic variability in Ayu are lower compared to those for other species.<br> At polymorphic loci, landlocked populations in Lake Biwa were homogeneous in allele frequencies, and amphidromous populations were similarly homogeneous on the whole. But between these two forms of Ayu, there were significant differences in allele frequencies at two loci (Me-l and Pgm).
