Effect of dietary enhanced Moina macrocopa(Straus, 1820) on the growth, survival and nutritional profiles of hybrid Nile tilapia fry

The cladocera Moina macrocopaserves as a common live feed that is suitable for most freshwater fish species. Seven diets for the cladocera, viz. Chlorellasp., rice bran, soybean meal, chicken manure, swiftlet waste, canola oil, and artificial micro pellet were compared in this study. This study's objective was to analyse the effect of enriched M. macrocopaon the growth, survival, and dietary profiles of hybrid Nile tilapia fry. The feeding experiment lasted for over 60 days. The M. macrocopaenriched with rice bran has produced the highest weight gain (5.83 g), survival (86.67%), protein (24.88%), and lipid (6.85%) in Nile tilapia fry. While, fatty acid such as α-linolenic acid (ALA; 4.67%) was found to be the highest in fry fed with M. macrocopaenriched with soybean meal. Arachidonic acid (ARA; 3.69%) and docosahexaenoic acid (DHA; 0.47%) were the highest in tilapia fry fed with M. macrocopaenriched with rice bran, while eicosapentaenoic acid (EPA; 6.33%) was the highest in tilapia fry fed with M. macrocopaenriched with Chlorellasp. In conclusion, the manipulation of nutrient such as protein, lipid and fatty acid Scompositions in M. macrocopadiet has successfully improved the nutrient compositions and production of Moinasp. culture that indirectly increased the growth and survival of hybrid tilapia fry.
