The four enzyme systems screened five loci was 12 in fulvus, 3 in lemnsicatus, 29 in lutjanus and 26 in madras were found to be polymorphic at p = 0.95 level. Diagnostic alleles help in clear distinctive species had been identified. An unweighted pair-group method with arithmetic mean (UPGMA) method was used to construct the dendogram to know the genetic relationship between the four species of snappers Lutjanus: fulvus, lemniscatus, lutjanus and madras based on genetic distance revealed the presence of three clusters showing the percentage similarity between lutjanus and madras 0.961%, leminiscatus showed 0.918% similarity with above two species and fulvus showed 0.890% similarity with above three species.
