The shortage of fish meal and fish oil provokes the search for alternative sources of these feed components. Insects that are part of the diet of animals, birds and fish, rich in protein and fat, can serve as such an alternative. The article presents the results of testing of compound feed for fish containing the fat of the larvae of the black soldier fly (Hermetia illucens) and a feed additive with probiotic activity. The use of the fat of the larva of the black soldier fly (Hermetia illucens) and a probiotic feed additive allows increasing the survival rate of fish from 90 to 95%, increase the conversion of feed and the average daily increase. The calculation of the economic efficiency from the use of compound feed, which includes feed additives of animal origin and additives with probiotic activity, showed an increase in profit when replacing compound feed made according to a standard recipe with compound feed with new feed additives. The economic effect of using compound feed with new feed additives amounted to more than 650 thousand rubles per year on small and medium-sized trout farms up to 20 tons per year.
