METHOD FOR ENRICHMENT ARTEMIA NAUPLII WITH MICROBIAL PROTEIN GAPRIN AND FATTY ACIDS FOR FEEDING STURGEON LARVAE Russian patent published in 2022 - IPC A23K50/80 A01K61/00 

FIELD: fishing industry.

SUBSTANCE: invention can be used for bio-encapsulation of Artemia nauplii for further feeding of sturgeon species larvae reared in industrial conditions. The method involves using Artemia nauplii enriched with a new high protein drug and essential high unsaturated fatty acids. As a protein preparation in saline solution with nauplii of the second naupliar stage, a suspension of microbial protein (gaprin) is initially introduced in the amount of 0,9 g/dm³, then after six hours, when re-enriching, a linseed oil emulsion is used in the amount of 0,6 g/dm³, while the survival of crustaceans after a 12-hour bio-encapsulation is more than 96% and Artemia size increases 1.3 times. Harvesting of enriched crustaceans and feeding of young fish with nauplii begins six hours after the second enrichment.

EFFECT: providing Artemia nauplii with a wide range of nutritional supplements using the enrichment method.
