Abstract

This paper is devoted to the study of protein synthesis by selected basidiomycete fungi-producers Pleurotus ostreatus and Aspergillus oryzae using microbiological methods with the aim of increasing the amount of protein in feeds during the preparation of balanced, protein-rich compound feeds for fish farming. It was identified that Pleurotus ostreatus and Aspergillus oryzae mushrooms have been shown to increase the amount of protein by 32.18% in 7 days, while Aspergillus oryzae mushrooms have been shown to increase the amount of protein by 168% in 7 days. - by 29.66%. Considering that the fish's need for protein is 30-35%, the fish's need for protein can be met with feeds with an increased protein content of 32.18%. Macroscopic fungi predominantly exhibit protein and enzymatic activity from 5-7 days growth. Since feed products are mainly polysaccharides, the growth and development of microorganisms in them, as well as the production of products, takes a certain period of time
