The effect of commercial feed enrichment with Piper betle leaf extract on the growth and survival rate of tilapia (Oreochromis niloticus)

Abstract

This research aimed to examine effect of commercial feed enrichment with Piper betle leaf extract on the growth and survival rate of tilapia (Oreochromis niloticus). This study used an experimental method with 15-20 g tilapia seed as test organisms at a stocking rate of 150 fish/m2. A Completely Randomized Design was used with five treatments and three replicates. The treatments were: A (pelleted feed/control); B (10% Piper betle leaf extract/kg feed); treatment C (15% Piper betle extract/kg feed); treatment D (20% Piper betle leaf extract/kg feed); and treatment E (25% betel leaf extract/kg of feed). The parameters observed during this study were the net increase in biomass and survival rate of the tilapia seed. All data were tabulated, then analysed using an analysis of variance (ANOVA). Water quality parameters in each treatment remained within acceptable limits for tilapia grow-out throughout the study, with pH 6.0-7.96; temperature 27.1 - 34.8 C; DO 3.7 - 4.8 ppm and 0 ppm ammonia. The Piper betle leaf extract concentration in treatment D (20%) gave the best results, with 342.33 10.60 g net increase in tilapia seed biomass and 100% 0% survival rate.
