Data collected on fish feeding show that adult decapods serve as food for large numbers of Black Sea coastal fish and even mammals. With respect to the nutritional qualities of decapods, studies have shown that the fat content in a dry-weight percentage of soft substance reaches 8 in the shrimp Leander Squilla L., and 20 in crabs Eriphia spinifrons Herbst. The amount of protein in percentage of dry body weight reached 64 in Leander squilla, an averaged 58.2. It averaged 54.46 in Pachygrapsus marmoratus Fabr., and 59.39 in Eriphia. The digestibility of decapods, particularly shrimp, was 78-84 for flounder and perch. Various substances found in the nutrition of fish were determined on the basis of the biological features of this organism, and they serve to explain the individual moments of the biology of the fish.
