Online published on 16 November, 2019. Abstract Present study was aimed to investigate the effects of two organophosphate pesticides (dimethoate and chlorpyrifos) on some blood biochemical parameters of juveniles common carps (Cyprinus carpio var. communis). Fingerlings were subjected to bioassays divided into 5 experimental groups in range finding test on the basis of which the doses for definitive tests were selected. The acute bioassay toxicity tests were carried out in triplicates for 96 hours with a control group run parallel to the experiment. Data obtained was analyzed as per Finney's probit to determine LC50 values. The mean lethal concentration (LC50) values for dimethoate and chlorpyrifos were found 1.1ppm and 3.8ppb respectively. The samples were investigated for various blood biochemical indices such as total protein (TP), serum albumin (SA), serum globulin (SGLO), alanine aminotransferase (ALT), asphartate aminotransferase (AAT), serum bilirubin (SB), serum glucose (SGLU), serum cholesterol (SC), and lactate dehydrogenase (LDH). All the liver enzymes (AAT, ALT, SB & LDH) and glucose (SGLU) were found increased while as TP, SA, SGLO, SB and SC were found decreased than the normal. Chlorpyrifos, was however, found to alter the biochemical indices more profoundly than dimethoate. The results indicated the organophosphate pesticides are intensely harmful for fish health. Their entry to natural waterbodies must be stopped besides ensuring their judicious application around the catchment area. Top Keywords Biochemistry, Chlorpyrifos, Dimethoate, Fish, LC50, Toxicity.
