The present study was undertaken to evaluate the lethal toxicity and stress of commercial formulations of carbosulfan (Aatank) insecticide, glyphosate (Roundup) and atrazine (Rasayanzine) herbicides toward freshwater air-breathing fish Channa punctatus (Bloch). The 96 h LC50 values, determined in a semi-static system by probit analysis as 0.268, 32.540 and 42.380 mg/l for carbosulfan, glyphosate and atrazine, respectively, indicated that the fish were more sensitive to carbosulfan than the other two herbicides. There were large variations in the safe levels estimated by different methods for the pesticides. In addition to dose and dose-time dependent increase in mortality rate, stress signs in the form of behavioral changes were observed in response to the test pesticides
