Abstract

Feed is one of the obstacles in shrimp farming because of the high price of feed. For this reason, a breakthrough is needed, namely the addition of natural ingredients in the feed that can increase shrimp growth. The purpose of this study was to determine the positive impact on the addition of Rhizopora apiculata leaf extract and the best dose to increase the growth of vannamei shrimp. This research method used an experimental Completely Randomized Design (CRD) 4 treat ments with 3 replications with the test feed using feed with the addition of Rhizopora mucronata leaf extract with several doses such as: 0 mg/kg feed (A); 1,5 mg/kg feed (B); 1,7 mg/kg feed (C); 1,9 mg/kg feed (D). Observations were made for 28 days with feeding 3 times every day. The results showed that the application of R. mucronate mangrove leaves was able to increase growth with the highest yield, namely at a dose of 1.9 mg/kg feed (D) which achieved an absolute growth of 5.46g. Water quality was desc ribed as temperature with 30 –31°C, salinity around 20 –21 ppt, and pH 7,7–8,0.
