Prospects of using adaptogens to stimulate nonspecific resistance and reduce stress factors of aquaculture facilities

The article considers the possibility of using adaptogens based on lactobacilli that stimulate nonspecific resistance and help reduce the impact of stress factors on aquaculture facilities as a result of the current difficult situation on the market of feed and feed additives for trout. The object of the study was authentic strains of lactobacilli − Lactobacillus brevis 1.5, L. brevis 1.7 and L. brevis 2.6. Under experimental conditions, the biochemical activity of lactobacilli was evaluated in relation to glucose, sucrose, mannitol, L-arabinose and glycerol; antibacterial activity and the ability to co-culture. According to the results of the study, the most promising strains were selected for use as a basis for the development of biologics of targeted adaptogens
