Abstract

Papaya leaf extract is known to have various benefits, including the papain enzyme which can function as a protein digester and improve the fish's immune system. The use of natural ingredients such as papaya leaf extract can also reduce dependence on synthetic chemicals, making it safer for human health and the environment. Based on the explanation above, it is necessary to conduct research on the effect of giving different doses of papaya leaf extract on the specific growth rate, feed conversion ratio and also the water quality of African catfish (Clarias gariepinus) seeds. This research was conducted in June - August 2024 at the Fisheries Production Laboratory of the Matauli Fisheries and Marine College. The effect of adding papaya leaf extract to feed with different doses on the specific growth rate, feed conversion ratio and water quality of African catfish (Clarias gariepinus) seeds produced the best results. The best treatment for Specific Growth Rate was in the P1 treatment of 1.405%, Feed Conversion Ratio of 1.411, and water quality in the form of temperature and pH which were in optimal conditions. This dose can be an alternative as a natural ingredient that has benefits to support an environmentally friendly and sustainable catfish (Clarias gariepinus) seed cultivation system.

Abstract

The application of local probiotics in commercial feed not only contributes to aquaculture efficiency but also opens up opportunities for utilizing inexpensive and easily accessible local materials as alternative environmentally friendly feed additives. Biologically, probiotics work by enhancing the balance of intestinal microflora, improving nutrient absorption, and strengthening the fish's immune system against environmental stress and pathogenic infections. Through this mechanism, the inclusion of local probiotics in feed can be an effective approach to naturally and sustainably enhance the physiological performance of fish fry. This study aimed to determine the effect of adding locally-sourced probiotics to commercial feed on the growth and survival of Siamese Pangasius (Pangasianodon hypophthalmus) fry. The probiotics were formulated using local ingredients such as banana fronds, turmeric, fine rice bran, yeast, molasses, and Yakult, and were applied to commercial feed at various concentrations. The research was conducted experimentally using a Completely Randomized Design (CRD) with four treatments and three replications: P0 (control, no probiotics), P1 (10 mL probiotics/kg feed), P2 (20 mL/kg feed), and P3 (30 mL/kg feed). Observed parameters included growth, feed conversion ratio (FCR), and survival rate (SR). The results showed that treatment P2 yielded the best outcomes, with the highest growth rate, lowest FCR, and significantly higher survival rate compared to the control. In conclusion, enrichment of commercial feed with local probiotics at a dosage of 20 mL/kg significantly improved the growth performance and survival of Siamese Pangasius fry (p<0.05).
