The effects of extracts from the fruits of Sponge plant (Luffa cylindrica) on the proximate composition of juveniles of Clarias gariepienus was investigated under laboratory conditions using static renewal bioassay for 56 days. The fish with average length and weight of 13.12±1.01cm and 14.72±3.63g respectively were exposed to sub-lethal concentrations of 883mg/L, 1766mg/L, 3532mg/L and 7063mg/L of extracts from the fruit of L. cylindrica. The physicochemical parameters of water contaminated with sub-lethal concentrations of Luffa cylindrica were examined. The pH of the test media was slightly acidic, which tend to increase as concentration of Luffa cylindrica extract increases. Dissolved Oxygen decreased while Conductivity and Total Dissolved Solids increased with increase in concentrations of Luffa cylindica extract. The changes in the physicochemical parameters were significant differences across the different concentrations (P<0.05). There were significant reductions (P<0.05) in protein, lipid, fiber and ash content (14.21±0.48% to 9.78±0.48%; 2.38±0.02% to 1.83±0.10%; 4.60±0.12% to 1.51±0.11% and 3.25±0.08% to 1.71±0.01 respectively) as the concentration of the extract increases. However, moisture content and carbohydrate content (74.67±0.61% to 82.55±0.43% and 1.44±0.48% to 2.62±0.48% respectively) significantly increased (P<0.05) from the control to the treated groups. The study revealed that the extract of Luffa cylindrical have adverse effects on the nutritional composition of Clarias gariepinus. Therefore, consumption of fish killed with piscicides should be discouraged because of the reduced nutritional values.
