Abstract: The objective was to detect genotoxic risk in the peripheral erythrocytes of fish specimens (Labeo bata) of juveniles and adults inhabiting sewage-fed waterbodies during pre-monsoon. The study was conducted in a sewage-fed fishponds inhabiting fish specimens (Labeo bata) during pre-monsoon season at Kolkata. For genotoxicity studies in peripheral erythrocytes of fishes of two age groups viz. juvenile and adults (5 nos. of fishes in each group). The micronucleus (MN) and nuclear abnormalities (NA) were detected as per standard protocol. In the juveniles, the significantly (P<0.001 and P<0.01) increased frequency (%) of MN (0.69 ± 0.06), BN (0.65 ± 0.05), NN (0.55 ± 0.05) and RN (0.79 ± 0.01) when compared to adults (0.47 ± 0.04, 0.46 ± 0.05, 0.40 ± 0.07 and 0.51 ± 0.04). It is concluded that there was a tendency of genotoxic risk in the juveniles of L. bata compared to adult?s specimens but not alarming. The cause for genotoxicity is unexplored. It is suggested that regular monitoring of genotoxins in the waterbodies of fishponds.
