Abstract

Aquatic ecosystem is the natural habitat of fish and water pollution that directly affect underwater fish and human beings are indirectly at high risk by consuming these fish. This study investigated the effects of nickel accumulation on catalase activity Clarias gariepinus. The level nickel bioaccumulations were determined after the exposure of the fish sample to concentrations of nickel using of Principle of Atomic Absorption Spectrophotometer (AAS 240 FS) and the effects of accumulation assessed using catalase as a bioindicator. The results indicated that a short-term exposure to nickel induced stress reaction in fish as there was an increase in the catalase activity. Thus exposure of fish and other aquatic organisms to toxicants such as nickel could lead to physiological stress.
