Author(s): M.Kanagaraj* and D. Manivelu

Abstract: The piscicidal activity of dry latex powder of Euphorbia tirucalli plant which is belonging to Euphorbiacae family and this latex powder against the fish tilapia Oreochromis mossambicus in laboratory condition was investigated. Toxicity of latex powder of this plant was timely as well as dose dependent against with fish Oreochromis mossambicus. This study reports that the decreasing nature of hematological parameters of freshwater fishes Oreochromis mossanbicus when treated with Euphorbia tirucalli latex powder at minimum concentration 0.04mg/l. The blood samples and tissue samples were analyzed according to the acquired result of the Euphorbia tirucalli latex powder is toxic to freshwater fish O. mossambics. This kind of physiological change may directly affect the survivability of these fish in their natural habitat. So, the use of this toxic plant should be a monitor in aquaculture areas. The present toxicity study, at the end of 28 days, there was considerable (P<0.05) alteration in different hematological parameters and biochemical parameters.
