Abstract
Among the extraction of aquatic biological resources in the Far East and in Russia as a whole, Pacific salmon occupy the second place in the total catch of fish. A feature of the physiology of Pacific salmon is pronounced transformations during the period of putina, namely, changes in color, body shape, head, jaw curvature and tooth enlargement, different mass indicators of fish and the chemical composition of muscle tissue. In this regard, a differentiated approach is needed when developing standard-setting indicators for verifying Pacific salmon catches. The conducted studies allowed us to determine the norm-forming indicators in the production of frozen fish from pink salmon and chum salmon from different production areas, depending on their biological state.
