The use of phytobiotics in fish feeding as an alternative to antibacterial and probiotic preparations (review)

Relevance . The use of antibacterial drugs as feed additives for many years has made it possible to reduce the risk developing infectious pathologies and, a result, increased productivity industry, in addition obvious advantages, constant antibiotics develops bacterial resistance, negatively affects representatives normoflora biocenoses and an accumulating effect aquaculture. One ways increase is probiotic strains with pronounced antagonistic characteristics against pathogenic microorganisms. It should be noted that optimal fish growth, high level species-specificity structural microbiome necessary, which ultimately cannot guarantee effectiveness commercial feeding diets. Results presented scientific data on phytobiotics indicate not only stimulating growth fish, but also antioxidant immunostimulating effect. Separately, worth noting tested plants A. hydrophila microorganisms (purslane leaf powder; dogwood fruit extract; combination essential oils thyme, red thyme rosemary pepper; food nanoparticles cinnamon, extracts coriander, mallow, oak acorn; pandanus roofing extract), veronii (apricot seed powder), L. monocytogenes (basil clove S. agalactiae (Belgian quince extract). Hypothetically, this mechanism can explained by activation indicators nonspecific immunity, influence majority experiments anti Quorum Sensing This review aimed at describing global trend feeding.
