ABSTRACT

The present study evaluates the growth and survival of 21-days reared Penaeus vannamei Post larvae fed on enriched and un-enriched copepod Dioithona rigida and Artemia Nauplii. The 21 days larval rearing experiment reveals that the length and weight of the copepod Dioithona rigida fed larvae were significantly higher than that of Penaeus vannamei Post larvae fed on Artemia nauplii. The result of biochemical composition include moisture, lipids and fatty acids of shrimp larvae fed with different live feeds before feeding, the moisture and lipid contents of Penaeus vannamei larvae were; 82.01% and 21% respectively. But after feeding experiment the shrimp larvae fed with un-enriched Artemia nauplii and copepod, exhibitedthe final moisture and lipid contents of 77.69 %; 77.88 % and 14%;30% respectively. Further, the n-3 highly unsaturated fatty acidscontent was found to be higher in both enriched and unenriched copepodfed Post larvaewhen compared to the Artemia nauplii fed Post larvae. The study concluded that the superior nutritional composition especially n-3 highly unsaturated fatty acidsof Dioithona rigida can enhance the growth and survival of the shrimp larvae.
