Experience of using dry biomass of methanotrophic bacteria in the enrichment of artificial feeds for Siberian sturgeon juveniles of the Ob population

The article discusses the results of a study on the enrichment of artificial feeds with dry biomass of methanotrophic bacteria of 10 and 20% concentration and fatty acids (treatment “Arfit”, linseed oil). The data on the increase in body length and weight, the survival rate of Siberian sturgeon juve...

Description
Summary:The article discusses the results of a study on the enrichment of artificial feeds with dry biomass of methanotrophic bacteria of 10 and 20% concentration and fatty acids (treatment “Arfit”, linseed oil). The data on the increase in body length and weight, the survival rate of Siberian sturgeon juveniles, depending on the applied preparations introduced, are presented. The best results were obtained when 10% of dry biomass of methanotrophic bacteria and HUFA were added to the feed (acceleration of weight growth by 44%, linear growth by 38%). The presented results are aimed at developing some elements of the technology for enriching artificial feeds with microbiosynthesis products.
