Abstract: The main aim of the toxicological evaluations are estimating the maximum dose that may be tolerated by animals throughout their life time without showing any adverse effect. The lethality of a toxicant to a particular organism is expressed in terms of mortality and time. The LC50 is the concentration of a chemical which kill 50 % in a group of experimental aquatic animals with in a given time period. Thus, the toxicity of a copper is evaluated in this study and identified 260ug/l copper kills 50 % of fish Catla catla. This is highly helpful in the determination of safe level (or) tolerable level of copper to the aquatic environment.
