Application of Bacillus spp. Bacteria as a Probiotic for Enhancement of Growth and Production Parameters in Indian White Shrimp (Fenneropenaeus indicus) Ponds

Abstract

This investigation was performed with the aim of surveying the effect of Bacillus bacteria
administration, as a probiotic, on shrimp farms production efficiency. Indian white shrimp (Findiclffi)
was affected by a mixture of 5 species of Bacillus bacteria from PL 30 to PL 120 in 100 m2 earthen-ponds in three treatments: Treatment P consisted of shrimp that received the probiotic only in farming stage (PL 30 to PL 120) ; treatment PP was consistent of shrimp that received the probiotic in both hatchery (naupli 1, to PL 30) and farming stages, and finally control (C) that received no probiotic in either of the hatchery or farming stages . According to findings in the investigation shrimp survival rate, wet weight, final production, FCR and SGR improved significantly (p<0.05) with application of Bacillus bacteria , specially in treatment PP. To cite an example; survival rate, final production and FCR were,88.53 %, 25.56 Kg/100m2, and 1.73 respectively in treatment PP while 71.5%, 19.06 Kg/100m2 and 98 in control. However from total and carapace length points of view there were no significant differences observed among treatments (p>0.05).
