AB  - The toxicity of aqueous and ethanol extracts of <I>Parkia biglobosa</I> pods (55, 65, 75, 85 and 95 mgL <SUP>-1</SUP>) on <I>Clarias gariepinus</I> juveniles was investigated over a 96 h exposure period. Fish exposed to both extracts exhibited clinical signs of agitated behaviours, respiratory distress and abnormal nervous behaviours and deaths were recorded in some fish exposed to both extracts. No unusual clinical manifestations or deaths were recorded in control fish. However, signs and deaths were more in fish exposed to the ethanol extracts. The 96 h LC<SUB>50</SUB> values for aqueous and ethanol extracts were 296.14 and 225.48 mgL <SUP>-1</SUP>, respectively. Both extracts are of minimal toxicity and the maximum toxicant admissible concentrations for aqueous and ethanol extracts ranged between 2.96-29.61 mgL <SUP>-1 </SUP>and between 2.26-22.55 mgL <SUP>-1</SUP>, respectively. It was concluded that aqueous and ethanol extracts of <I>P. biglobosa</I> pods are toxic to <I>C. gariepinus</I> juveniles with the ethanol extract being more toxic.
