The article presents comparative data on the chemical and amino acid analysis of the muscle tissue of sturgeons of the natural ichthyofauna of the Volgograd reservoir and those grown in a cage farm in the natural temperature regime of the 4th zone of fish farming in the Russian Federation using balanced feeding. The results obtained indicate the saturation of the muscle tissue of sturgeons consuming artificial feed with amino acids. The difference in nutrition is reflected in the biological value of meat. An important indicator of the biological value of a product is the qualitative and quantitative composition of muscle tissue amino acids. The natural nutrition of the Volgograd Reservoir does not fully satisfy the sturgeon’s need for protein nutrition. Industrial methods of cultivation make it possible to optimally organize biologically complete feeding of fish, which contributes to the maximum manifestation of their genetic potential and production of functional products.
