The toxic effects of cadmium (CdCl2) on Clarias gariepinus in terms of physical and behavioural responses as well as 96 hrs LC50 were investigated. A total number of 150 samples of the fish were acclimated for a period of 14 days during which they were fed to satiation twice daily. The test was made up of five treatments with replicate in each case with the following nominal Cd concentrations: 00, 50, 80, 110, 140 and 170 mg/L. Each trough contained 10 fingerlings (10-20 mg). The experiment ran for a period of 96 hrs; and probit analysis was used in obtaining the 96hrs LC50. From the results: Cd toxicant elicited physical and behavioural responses such a.. View More»
