Abstract

Enzyme gene variability in the oil sardine, Sardinella longiceps, from three localities along the western coast of India was studied by starch-gel electrophoresis. Out of 19 loci scored, no locus was polymorphic by the 95% criterion. Seven loci were polymorphic at the P=0.99 level. The average heterozygosity ranged from 0.6% to 0.9%. These values are very low compared with those of other marine fish species.
