Abstract
A comprehensive study of 100 samples of fish meal produced in Russia in 2022-2024 and used in the production of compound feeds for aquaculture was conducted. The samples were divided via cluster analysis into five groups according to chemical composition: the largest group (>50%) was characterized by crude protein content 70.2±0.2%, crude fat 9.40±0.17%, ash 13.7±0.13%. Amino acid analysis revealed high value of protein composition: the sum of essential amino acids was 28.38-31.65 g/100 g of product, non-essential – 34.55-38.02 g/100 g of product. Analysis of essential amino acid ratios confirmed the absence of falsification in the studied samples. The lipid profile was characterized by the sum of eicosapentaenoic and docosahexaenoic acids at least 25% of the total fatty acid content. The acid value of fat in 95% of samples did not exceed 20 mgKOH/g, indicating high lipid quality. The obtained data can serve as a basis for developing specialized quality standards for fish meal for aquaculture feeds.
