Abstract
Probiotics are considered as one of the most significant components of 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 performance of Penaeus vannamei at different hypersaline condition under probiotics supplementation. A 60 days experiment trial was carried out at higher salinities (45, 50, 55 and 60 ppt) with probiotic. All the important water quality parameters such as total ammonia nitrogen, nitrite, total hardness, total alkalinity, pH etc. was found to be in optimum range after few weeks in all treatments and control but the effect was better in control (45 ppt) and T-1 (50 ppt). The growth performance of P. vannamei was found better in control and T-1 compared to the rest of the treatments. FCR was found to be significantly lower in control compared to T-3. A similar trend was observed with survival percentage. Average body weight gain, protein efficiency ratio, feed efficiency ratio and specific growth ratio was found better in control and lowest in T-3 (60 ppt). Hence it can be concluded that 45 and 50 ppt with probiotics is most suitable for culture as compared to other higher salinities.
