Description:
Fingerlings of Ciarias gariepinus were exposed to various sublethal concentrations (10.0, 20.0, 30.0. 40.0, 50.0 and 60.0 ~KL/L) formalin and the concentration of 0.0 ~KL/L formalin served as the control. The toxicant led to depressed weight gain in the fish. Severity of this depression was directly proportional to the toxicant concentrations. However, there was no difference (p〉0.05) in weight gain in test fish of various concentrations. Restlessness, loss of balance, erratic swimming behavior, respiratory distress, vertical movement and death, were observed in test media especially in the concentrations 60.0 and 50.0~Kl/L of formalin. Such observation were not recorded in the control tanks.
