ADDITION OF ORGANIC WASTE ON NILE TILAPIA (OREOCHROMIS NILOTICUS) COMMERCIAL FISH FEEDING

Nile tilapia (Oreochromis niloticus) is an important commodity in the aquaculture of freshwater fish in Indonesia, apart from its distinctive taste but also a good protein content for fulfilling community nutrition. However, the high demand for nile tilapia is not enough just to rely on fishermen, so it takes effort to increase the growth rate of it. This study aimed to determine the effect of shrimp waste and coconut pulp addition to enhance protein retention, energy retention and growth rate of nile tilapia (Oreochromis niloticus). This was an experimental study by means of completely randomized design method. There were five treatments and four replications in each treatment. The treatment used was the addition of shrimp waste and coconut pulp on commercial feed. Two hundred nile tilapia were used in this study. The study was conducted for 30 days by feeding three times a day. The research data were analyzed using ANOVA and Duncan. Based on the results of the study, it can be seen that the addition of 30% shrimp waste and coconut pulp flour to nile tilapia commercial feed (Oreochromis niloticus) significantly affected the energy retention value of 12,050%, protein retention of 21 245% and growth rate of 1.471%. Adding organic waste to commercial fish feed can boost the growth rate of nile tilapia.
