Effect of Gamal Leaves Extract (Gliricidia sepium) on Growth Rate and Feed Conversion Ratio of Bileh Fish (Rasbora sp.)

Abstract

This study aimed to determine the effect of adding gamal leaf extract in artificial feed on the growth rate and feed conversion ratio of bileh fish (Rasbora sp.). The method used in this research is the experimental method, with Completely Randomized Design experimental design. There were four treatments (P) given, with three replicates. The treatments were gamal leaf extract added to artificial feed at different doses, control/P1 = 0 ml/kg, P2 = 10 ml/kg, P3 = 20 ml/kg and P4 = 30 ml/kg feed. The research steps included the preparation of research containers, experimental fish, preparation of extracts and feed, maintenance of fish-fed experimental feed and collection of research data. Parameters calculated and evaluated included SGR (specific growth rate), ALG (absolute length growth), FCR (feed conversion ratio), and SR (survival). Data analysis used statistics (Anova). The results showed that the addition of gamal leaf extract had a significant effect on SGR, PPM, and FCR parameters (P < 0.05) but did not have a significant effect on SR parameters (P > 0.05). The best treatment was P4 (30 ml/kg) with SGR 1.57%, PPM 1.19cm, FCR 3.09 and SR 91.11%.

Effect of Pregnant Mare Serum Gonadotropin and Antidopamine on the gonads of female bileh fish (Rasbora maninjau)

“…Overfishing must be reduced, and efforts must be made to cultivate bileh fish for the community's needs. Researchers have studied the domestication of bileh fish in aquaculture containers [5], type of feed, and growth [6,7,8,9]. Bileh fish reared in aquaculture containers experience problems in gonad maturation.…”
