Evaluation of potential bacteria isolated from marine shellfish as probiotic for Penaeus monodon larviculture against pathogenic Vibrio harveyi

Probiotics have been widely used as an alternative treatment in aquaculture. This study was carried out to determine the ability of two potential probionts; Bacillus strain I24 and Exiguobacterium strain S66 in producing biofilm and reducing hemolysin production in two Vibriosp;Vibrio alginolyticusa...
