Abstract

The article presents generalized results of the experimental rearing of two-year-old rainbow trout using specialized trout feed by LLC «PROMETRIKA» in the conditions of the pool workshop of the scientific and production base Dukhovnitskoye Fish Farm (R. Dukhovnitskoye, Saratov Region) in 2022. An assessment of changes is given morphophysiological characteristics of fish and commercial qualities, mainly the degree of coloration of muscle fibers, with the help of which the efficiency of using the experimental feed with the content of the feed additive «AstaPet 10%» was determined. On the basis of the data obtained, it can be concluded that the use of this preparation, which enhances the color intensity of fish tissues in the feed of LLC «PROMETRIKA», has a positive effect, which allows us to recommend this preparation for use in factories for the production of feed for trout and, later on, in fish breeding enterprises engaged in their production grow.
