POTENTIALS OF Psidium guajava SUPPLEMENTED MEAL ON GROWTH PERFORMANCE AND SOME ORGANS FUNCTION PARAMETERS OF Clarias gariepinus JUVENILE

Abstract

This study evaluates the effects of Psidium guajava (guava) leaf extract supplementation on the growth performance and organ function parameters of Clarias gariepinus (African catfish) juveniles. Four dietary treatments were formulated: a control group (T1) and three experimental groups supplemented with varying concentrations of guava leaf extract (T2: 5g, T3: 10g, T4: 15g in 100ml of water). Fish were fed twice daily for eight weeks, and growth performance indicators such as weight gain and length gain were recorded. Additionally, liver and renal function parameters, including ALT, AST, ALP, total protein, urea, and creatinine levels, were analyzed. Results showed that T2 (5g guava supplementation) significantly enhanced weight gain (108g) and protein synthesis, while liver function remained stable. However, higher guava concentrations (T4) induced elevated ALT and AST levels, indicating potential liver stress. Renal function parameters showed improved nitrogen metabolism with lower urea and creatinine levels in the guava-supplemented groups. The study concludes that moderate supplementation with Psidium guajava (5g per 100ml water) can enhance growth and improve organ function in Clarias gariepinus juveniles, while higher concentrations may cause liver stress. This suggests that Psidium guajava leaf extract has potential as a cost-effective dietary supplement in aquaculture, with appropriate dosage management.
