Biofloc technology is recognized as sustainable, eco-friendly and economical technology for shrimp aquaculture due to its numerous beneficial outcomes such as disease prevention, maintaining water quality, and promoting growth. The present study was aimed to evaluate the effects of the nutritional profile biofloc and biochemical composition of Litopenaeus vannamei under biofloc different salinities. A 45-day investigation was conducted both with and without biofloc at various salinities (10, 20, 30, 35, 40, 50, and 60 ppt). After a few weeks of all treatments and controls, it was discovered that all the essential water quality parameters were within an optimal range. Floc volume was exanimate during the trial. The nutritional profile biofloc and biochemical composition of Litopenaeus vannamei were analyzed at the end of the experiment. Floc volume is increase with day of culture is increases but decrease with higher salinities. Amino and fatty acid profile of biofloc better in lower salinity. The proximate composition of shrimp was found good quality at low salinity. Hence it can be concluded that 10, 20 and 30 ppt under biofloc is better nutritional profile as compared to other salinities. The proximate composition of biofloc treatment shrimp found better than control.
