Abstract: Anthropogenic stresses alter different biochemical and physiological parameters in an organism. Measurement of these changes can be used to assess the health of the fish under study. In this study fishes (Labeo rohita) were collected from three different wetlands (Bhomra beel, Mathura beel and Kalyani lake), situated in the same geographical region but possessing different levels of anthropogenic threats. Fish health was monitored by examining changes in blood hematological parameters (Red blood cell count, hemoglobin, mean cellular hemoglobin content, mean cellular hemoglobin concentration, WBC count) as well as hepatic superoxide dismutase (SOD) activity & liver histology. SOD showed significant up regulation in response to oxidative stress. In this comparative study SOD activity showed more changes in mostly polluted wetland i.e., Kalyani Lake. In this study, liver histology showed few notable changes. Level of anaemia and leucocytosis was maximum in Kalyani lake and minimum in Bhomra beel. Comparison of liver histology among the three beels revealed more distinct apoptotic & necrotic changes along with periductular fibrosis and melanomacrophage centers in carps’ liver tissue samples collected from Kalyani Lake. It further reinforces the hypothesis of presence of more stressors in that particular polluted wetland i.e., Kalyani Lake.
