Latoh sea weed (Caulerpa lentillifera) contains high carbohydrates, low fiber and high mineral especially Na, Zn and Mg. This composition should be able to make it as a good mineral supplement. The objective of this study was to reveal the inclusion level of Caulerpa lentillifera in the diet. Fresh latoh was juiced finely and filtered with 60 mesh size filter. Then it was top dressed to commercial tilapia feed (crude protein 38%) with different level. There are 5 treatment and 3 replication i.e. 0%, 10%, 20%, 30%, and 40% latoh (v/w). The feed was dried for 24 hour at 550C. Number of 20 ind, +1,45 gr tilapia fingerling was reared in 20 l brackishwater (15 ppt) for 4 weeks. Fish was fed 4% bw/day for twice a day. Fish was weighted and water quality measured (DO, pH, and temperature) weekly. Data was analysed by MANOVA (Multivariate Analysis of variance) and Duncan Multiple Test with SPSS v.20. The result indicate that Caulerpa lentillifera should be incorporated to feed no more than 20% because of growth performance decreasing (Table 1.). There is tendency that 10% Caulerpa supplementation could improve growth, FCR and survival rate (Figures a-d).
