Abstract:
Biofloc technology is considered as sustainable, environment-friendly and cost-effective technology for shrimp aquaculture due to its several beneficial effects such as disease prevention, water quality maintenance, and growth performance. Present research work was designed to compare the growth performance and survival of Litopenaeus vannamei nursery phase under biofloc at different saline condition. A 45 days experiment trial was carried out at different salinities (10, 20, 30, 35, 40, 50 and 60 ppt) with and without biofloc. The growth parameters were analysis end of the experiment after forty-five days. Specific growth was measured fourth night. The growth performance of L. vannamei was found better in 20, 30 and 35 compared to control. Average body weight gain, protein efficiency ratio, and feed efficiency ratio, specific growth ratio, FCR and survival percentage was found better in treatment. Hence it can be concluded that 20, 30 and 35 ppt under biofloc is most suitable for culture as compared to other salinities.
