Fiji has a strong demand for shrimp but farmers hardly meet the demand due to inadequate knowledge of local ingredients. A nutrition study was conducted to evaluate growth performance of juveniles of freshwater prawn, Macrobrachium rosenbergii with low cost formulated diets using locally available ingredients. Experiment 1 included six diets ( fish meal + wheat, Fish meal + meat bone meal + wheat, Fish bone meal + fish meal + wheat, Meat bone meal + wheat, Meat fish meal + fish meal + wheat and Meat fish meal + wheat). Diets for Experiment 2 were Fish meal + wheat, Fish meal + meat meal, Fish meal + meat meal + crest
tilapia pellet, Fish meal + meat meal + copra meal, Fish meal + wheat + pea meal and Crest tilapia pellet . Each experiment (6 diets x 3 replicates) was done in the Laboratory. Juveniles were fed twice a day for a period of three and four weeks in Experiment 1 and 2. Results indicated no significant (P>0.05) differences in water quality parameters. All nitrates, nitrites and ammonia
concentration were less than 0.2 mg/L. Fat and crude fiber content was lowest and highest in crest pellet tilapia (4.60% and 17.98%). Experiment 1 showed slight variations in the growth performance. In Experiment 2, crest tilapia pellet indicated better result in weight gain (7.0
