Assessment of Genotoxicity in Two Fish Species from East Kolkata Wetlands: Impacts and Insights amidst Shifting Ecological Dynamics
Anuradha Gupta | Soumendra Nath Talapatra [13]
Abstract: The present study was examined genotoxicity especially micronucleation (MN) and nuclear abnormalities (NAs) in the peripheral erythrocytes of two selected fish species (Labeo bata and Oreochromis sp.). These fishes were collected from two sites viz. Bhojerhat as site A and Chowbhagaas site B of East Kolkata wetlands (EKW). In the fishes (just died) blood drawn from heart, smeared, and stained with Giemsa followed by scoring of percentage frequency of MN and NAs. In the present study, MNand NAs frequency (%) for both L. bata and Oreochromis sp., were higher in the site B without significant change when compared to site A. It is concluded that the genotoxicity through MN and NAs test in these studied fish did not show genotoxic effect as mutation risk, which may be due to COVID - 19 pandemic followed by lockdown. It is suggested in future to evaluate the physico - chemical properties and the concentration of metal (loids) in the river water and sediment of EKW.
