Shrimps provide high quality rich protein, amino acid, calcium and minerals for human body, while low in calorie and fat and post larva of shrimp was use as feed in commercial finfish hatchery. Lipid of shrimp contains mostly polyunsaturated fatty acids (essential fatty acids). The main purpose for this alteration is that Litopenaeus vannamei has a higher stocking density, higher innate immunity, faster growth rate, yield and lower production costs than Penaeus monodon. The values of nutritional composition of Litopenaeus vannamei post larvae: crude protein: 13.05±0.25%, lipid content: 1.66±0.06%, carbohydrate content: 4.25±0.03%, moisture content: 79.45±0.60% and ash content: 1.59±0.04% were found. Keywords: Litopenaeus vannamei, post larvae, nutritional composition, protein, lipid Introduction India is the second largest producer of fish in the world contributing to 5.68% of global fish production. The total fish production during 2017-18 is at 11.08 million metric tonnes with the overall growth 6.3% [1] . India is also a major producer of fish through aquaculture and ranks second in the world after China. The potential area of Indian coast brackishwater farming has been estimated at 1.19 million hectare(s), of which only 13.14% {0.157m hectare(s)} is so used 2 . In Indian crustacean aquaculture has recently been facing severe crisis owing to massive setbacks suffered by the shrimp culture industry, as rampant outbreak of viral and bacterial diseases still persist and also due to the imposition of legal regimes such as Coastal Regulation Zone Act etc. Shrimp is one of the world’s most popular and most cultivable shellfish. Shrimps provide high quality rich protein, amino acid, calcium and minerals for human body, while low in calorie and fat 3 and post larva of shrimp was use as feed in commercial finfish hatchery. Lipid of shrimp contains mostly polyunsaturated fatty acids (essential fatty acids). These essential fatty acids are available in shrimp provides health benefits for human e.g., eye (retina) and brain development 4 . In India, there is no published report on biochemical composition of post larvae Litopenaeus vannamei. Therefore, the present investigation is the first of its kind on proximate composition of basic biochemical constituents, such as total protein, carbohydrate, lipid, moisture and ash in the muscle of Litopenaeus vannamei. Materials and Methods The shrimp, Litopenaeus vannamei post larvae (PL15) were procured from commercial shrimp hatchery at Kotada, Kodinar, District-Gir-Somnath, Gujarat. Post larvae were packed in oxygenated polythene bags and brought to Aquaculture laboratory, College of Fisheries Science, Veraval. The PL were stocked in 200L plastic tank at 27±1 ºC water temperature and 25±1 ppt water salinity with adequate aeration and feeding for acclimatization. After acclimatization process measure the biochemical composition of post larvae. Proximate composition analysis Proximate composition of samples was analyzed using standard methods of AOAC [5] . Crude protein content was analyzed by the Kjeldahl method. Crude lipid was estimated with the Soxhlet apparatus. Moisture and ash content were determined using the incubator and muffle furnace.
