Effect of addition of fermented restaurant waste meal in artificial feed on the growth of nile tilapia (Oreochromis niloticus)

Abstract

This research aims to determine the optimal probiotic concentration and to analyze the effect of addition of fermented restaurant waste meal (FRWM) in feed to growth of nile tilapia. The research was carried out from February-June 2019 at Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This research used experimental method with a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments given consisted of addition of 0, 10, 20, 30 and 40% of FRWM in feed. The parameters observed included changes in the nutritional value of restaurant waste, daily growth rate, survival, feed conversion ratio, and water quality. Data were analyzed using analysis of variance. and was further analyzed using Duncan’s multiple range test 5%. The results showed that the addition of 8% probiotic concentration was able to provide the best change in the nutritional quality of restaurant waste by increasing feed protein by 50.83% and decreasing crude fiber by 30.74%. The use of 30% fermented restaurant waste meal in feed gave the highest daily growth rate of 1.57% and the best feed conversion ratio of 0.57 with a survival rate ranging from 75-90%.
