Probiotic effect of lactic acid bacteria in the feed on growth and survival of fry of Atlantic cod (Gadus morhua)

摘要: A growing concern for the high consumption of antibiotics in aquaculture has initiated a search alternative methods disease control. Improved resistance against infectious diseases can be achieved by use probiotics. Probiotics are live microorganisms supplemented food or feed which give beneficial effects on intestinal microbial balance. In present study dry containing lactic acid bacteria (Carnobacterium divergens) isolated from Atlantic cod (Gadus morhua) intestines was given to fry. After three weeks feeding fry exposed virulent strain Vibrio anguillarum. The death rate recorded during further with feed. certain improvement obtained, and at end experiment dominated flora surviving fish bacteria. No obvious growth inhibition V. anguillarum observed an vitro mixed culture this bacterium C. divergens intestines.
