Abstract: Shrimp farming is one of the most important aquaculture and economically lucrative practices of maritime countries. Providing a Specific Pathogen Free (SPF) shrimps to the farmers is a big challenge that must be addressed to meet the demand. In general, microalgae are utilized in aquaculture as a live feed for the shrimps. The retention time of food in the gut is lower than in mysis and postlarvae, while feces production is high. Therefore, knowledge of the optimum level of protein, lipids and carbohydrates would be effective in reducing feed costs and water pollution. The types and levels of these nutrients in the diet have been shown to affect the growth. Thus, present study focused to examine the biochemical profile of Penaeus monodon and Litopenaeus vannamei shrimp culture at different stages from Z3 to PL20. From the results, it has proven that the biochemical concentration will be vary (Protein - 16.06±0.582 to 21.98±0.81, Carbohydrate-3.82±0.576 to 8.32±0.649, Lipid-11.22±0.322 to 24.02±0.396) when fed with different microalgae in both the shrimp species.
