Nutritional Status Of Moina Macrocopa (Straus, 1820) Enriched With Different Feeds And Its Effects On Growth And Survival Of Hybrid Nile Tilapia Fry
The cladocera Moina macrocopa serves as a common live feed that is suitable f or most freshwater fish species. Seven diets for the cladocera, viz. Chlorella sp., rice bran, soybean meal, chicken manure, swiftlet waste, canola oil, and artificial micro pellet were compared in this study. The obje...

| Summary: | The cladocera Moina macrocopa serves as a common live feed that is suitable f or most
freshwater fish species. Seven diets for the cladocera, viz. Chlorella sp., rice bran,
soybean meal, chicken manure, swiftlet waste, canola oil, and artificial micro pellet were
compared in this study. The objectives of the study were to identify the population
density, survival and, productivity of Moina macrocopa when fed with different
dietaries enrichment; to compare the protein, lipid and fatty acid analysis of enriched
Moina macrocopa with unenriched and Artemia nauplii; and to analyses the effect of
enriched Moina macrocopa on the growth, survival and dietary profiles of hybrid Nile
tilapia fry. Feeding of M. macrocopa with different diets for 16 days of cultivation has
indicated that M. macrocopa fed with rice bran produced a higher population density
(24.81 ind/mL) and survival (97.92%) compared to other diets. In terms of nutritional
value, protein (77.09%) and lipid (16.62%) was highest in M. macrocopa enriched rice
bran, while, fatty acids such as α-linolenic acid ALA (6.91%) and docosahexaenoic acid DHA (1.53%) were higher in M. macrocopa enriched with soybean meal,
eicosapentaenoic acid EPA and arachidonic acid ARA were higher in M. macrocopa
enriched with Chlorella sp. (8.78%) and rice bran (4.20%) respectively. M. macrocopa
was used as a feed for hybrid tilapia fry over 60 days and has produced highest weight
gain (5.83g), survival (86.67%), protein (24.88%) and lipid (6.85%) when f ed with M.
macrocopa enriched rice bran. While, the fatty acid ALA was found to be highest
(4.67%) in fry fed with M. macrocopa enriched with soybean meal. ARA (3.69%) and
DHA (0.47%) were highest in tilapia fry fed with M. macrocopa on a diet enriched with
rice bran, while EPA (6.33%) was highest in tilapia fry fed with M. macrocopa enriched
with Chlorella sp. In conclusion, the manipulation of nutrient such as protein, lipid and
fatty acid compositions in M. macrocopa diet has successfully improved the nutrient
compositions and production of Moina sp. culture that indirectly increased the growth
and survival of hybrid tilapia fry. |
