| dc.description.abstract | In order to assess the acute toxicity of mercury on Clarias gariepinus, 108 fish of mean weight 51.27 g ± 2.01 and mean length 20. 2 cm ± 0.72 were divided into six groups of six fish each. The different groups were exposed to the different concentrations of 0 mg/L, 0.3 mg/L, 0.5 mg/L, 0.8 mg/L, 1 mg/L et 1.50 mg/L for a period of 96 hours. The experiment was triplicated. The results revealed that all the fish of groups exposed to 0 mg/L of HgCl2 (control) survived whereas all the fish of groups exposed to 1 mg/L and 1.5 mg/L died. The determination of 96 hours LC50 was carried out by computing the mortality results in Probit program of SPSS (version 17.0). The median lethal concentration was 0.60 mg/L with lower and upper confidence limits of 0.135 mg/L and 3.519 mg/L respectively at 95% | en_US |
