Use of probiotics Bacillus cereus var. toyoi and Bacillus subtilis C-3102 in the diet of juvenile Nile tilapia cultured in cages

This study aimed to evaluate gut colonization by probiotic bacteria, and their influence on the bacterial microflora, hematological profile, growth rate and proximate composition, and water quality parameters in the cultivation of Nile tilapia juveniles of the Genetically Improved Farmed Tilapia (GI...
