Combination feeding on the growth of Saline Tilapia (Oreochromis niloticus)

Abstract

The combination of commercial feed and fermented bran is an alternative to reduce production costs from aquaculture activities. The purpose of this study was to analyze the growth and survival of tilapia by reducing the frequency of feeding commercially replaced with fermented bran. This research was conducted from January 2022 to February 2022 at the Ujung Batee Brackish Water Cultivation Center, Mesjid Raya, Aceh Besar. This research method used a completely randomized design (CRD) with five treatments and three repetitions, namely treatment A (5% commercial feed without fermented bran), treatment B (4% commercial feed and 1% fermented bran), treatment C (3% commercial feed and 2% fermented bran), treatment D (2% commercial feed and 3% fermented bran), treatment E (1% commercial feed and 4% fermented bran). Based on the results of research that has been analyzed by ANOVA test shows that the combination of commercial feed and fermented bran to fish has an effect on growth, but does not affect the survival rate of fish.
