Abstract: Pesticides and chemicals used in agriculture may finally inter aquatic environment and accumulate in the food chain and may cause serious ecological and health problems. The aim of the present study was to investigate acute effects of cypermethrin and rogor as dangerous agricultural chemicals and to assess and compare mortality rates of these chemicals on Clariasbatrachus in the form of LC50 for 96hrs.Fish were exposed to different concentrations of cypermethrin and rogor (between 0.02 - 0.1mg/l for cypermethrin and 10-18mg/g) for 96 h in 20 L glass aquaria. The 96hrs LC50 value obtained for cypermethrin and rogor was .032 mg/l and13.517mg/l and it indicates that cypermethrin and rogor are highly toxic toClariasbatrachus. Further studies arerecommended to investigate the effects of these harmful chemicals on fish physiology and histology and theiraccumulation in fish tissues. Although these chemicals are thought to be less toxic in field conditions due to their adsorption to sediments, these data are useful when assessing potential ecosystem risks.
