Abstract

The behavioural and serum liver enzyme responses of juvenile catfish (Clarias gariepinus) were evaluated for 72 hours. Thirty-six (36) healthy fishes with standard weight, 20 ± 1.52 g and standard length, 18.25 ± 0.50 cm were used for the experiment in non-renewable bioassay system. The test fish exhibited stressful behavioural changes such as erratic swimming, vertical swimming, gasping, and body discolouration. The 24 and 48-hours LC50 were determined to be 96.937 and 9.765 mg/ml respectively. Increased serum aspartate amino transferase and alanine transferase concentrations were recorded on the final day of the experiment (p<0.05).
