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,
with low cost formulated diets using locally available ingredients.
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
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
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
showed slight variations in the growth performance. In
, crest tilapia pellet indicated better
result in weight gain (7.04 ? 2.96 mm), carapace, abdomen and body length (4.74 ? 1.94, 5.57? 0.62 and 5.57? 0.62), specific
growth rate ( 2.38 ? 0.53) and feed intake (1.31 ? 1.19) but no significant differences (P≥0.05) were observed in either of the
experiment. The cost of making each feed was almost same (0.53 - 0.58 Aus $/Kg). The findings indicate that the ingredient
inclusion level for local ingredients available in Fiji for freshwater prawn juveniles
could be quite flexible.
