FEED FOR FISH (VARIANTS) WITH PROBIOTIC FEED ADDITIVE Russian patent published in 2018 - IPC A23K50/80 

FIELD: fishing and fish breeding.

SUBSTANCE: invention relates to the fishing industry and fodder production, namely to the production of food for fish that are grown in natural water bodies and in cage-basin fishery systems. Feed contains a filler in the composition of the standard food ration and a probiotic fodder additive. Food for fry is used at least every 2 hours during the daylight hours, and for bimonthly – at least 2 times a day. Probiotic supplement contains the dried biomass of two strains: a strain of bacteria Enterococcus faecium 1-35 with a titer of living bacteria 1.3×10⁸–1.8×10⁸ CFUs and a strain of bacteria Bacillus megaterium B-4801 with a titer of living bacteria 1.0×10⁸–3.3.×10⁸ CFU, applied in a mixture in equal amounts to the filler. In the first variant, a sunflower meal containing 1 g of feed additive is used as a filler. Live bacteria Enterococcus faecium 1-35 1.8×10⁸ CFU and living bacteria Bacillus megaterium B-4801 1.0×10⁸ CFU. In the second variant, as a filler, a tremor containing 1 g of the feed additive, live bacteria Enterococcus faecium 1-35 1.3×10⁸ CFU and living bacteria Bacillus megaterium B-4801 3.3×10⁸ CFU.

EFFECT: implementation of a group of inventions makes it possible to increase the safety of fry and to increase the growth in the live weight of fish.
