|Abstract:||Goldfish (Carassius auratus) exposed to a CuSO4 solution of 255 μg Cu2+/l for 2 weeks and then transferred to copper-free water for 1 week, or exposed to a CuSO4 solution of 288 μg Cu2+/l for 2 h, showed 88.9% protection against Ichthyophthirius multifiliis as compared to 5.6% and 3.7% respectively in the control groups. The 24, 48, 72 and 96-h LC50 values for copper sulphate in goldfish under local tap water conditions (pH 6.8-7.4 and hardness 72.5-80.3 mg CaCO3/l) were 365, 355, 301 and 288 μg Cu2+/l as CuSO4·5H2O respectively. The copper levels of fish tissue and tank water were also determined and its role in protection against I. multifiliis discussed. © 1993.|
