Aquaculture has become the fastest growing sector of food production in the world. Feeding practices in aqua farming usually play an important role, and the addition of various additives to a balanced feed formula to achieve better growth is a common practice. To meet the ever-increasing demand, aquaculture continuously requires new techniques to increase the production yield. Fish probiotics, as one of the alternatives to antimicrobials, are live microbial supplements, which beneficially affects the host by improving its microbial balance. The approach is to increase the yield through improved water quality and reduced mortality rates.
With other benefits include direct effects like immunity enhancement, disease control; feed consumption, effects on the organism through microbial colonization of the digestive tract and indirect/environmental effects i.e. water quality improvement, reduction of water exchange, and reduction of sludge accumulation. All of these have a synergist impact on the financial performance of the farm.
