Abstract:
Live feed is particularly essential for the growth of larval forms in aquaculture, as they more easily ingested and digested, they do not affect the water quality and contain essential growth factors such as fatty acids and amino acids. Skeletonema costatum has been widely used both in extensive and intensive hatchery systems of Penaeus monodon. S. costatum to the penaeid shrimp in the zoea stage resulted in a survival rate of 30% to the mysis stage. This study is conducted to estimate and compare their nutrient composition and to find out the best suited feed according to the nutritional requirements of zoea stage of Shrimp. Two culture medium are considered as treatment (T1- Enriched medium compost+ silica + B2+ B12, T2- Raw medium compost+silica) for culturing of S. costatum in different temperature respectively 24℃, 27℃, 30℃ for six months and proximate composition with fatty acid, micronutrients was analyzed. Ash content of different samples showed significant difference between treated samples at 24℃ and 27℃ temperature (p<0.05). Protein, lipid, micronutrient, fatty acid content of different samples showed significant difference (p<0.05) between treated samples. Protein, lipid, EPA and DHA content showed highest value in raw medium at 30℃ which accomplish the requirement of Zoea stage of Shrimp. T2 (Raw medium) identified as best treatment and it will be recommended for shrimp zoea stage.
