Bioaugmentation of biofloc system with enzymatic bacterial strains for high health and production performance of Penaeus indicus

Abstract The beneficial effects of two probiotic bacterial strains Marinilactibacillus piezotolerans and Novosphingobium sp. during the culture of Indian white shrimp, Penaeus indicus, under biofloc and clear water system were evaluated. The experimental variation were CW1 (M. piezotolerans in clear...
