During winter starvation, both stored reserve substances (fat, glycogen) and body structures such as muscle, liver, and skeletal tissue proteins are utilized. Muscles, which make up the bulk of the fish body, store substantial amounts of nutrients. The metabolic rate of fishes can be judged from changes in the chemical composition of these nutrients. The purpose of this work was to study the chemical composition of the muscles of fingerlings of pond carp and of hybrids of the latter with river carp; fishes of different weight groups were used. During 7 months of endogenous winter feeding the dynamics of dry matter, crude protein, lipids, glycogen, and, from the mineral compounds, phosphorus were investigated. It is evident from the data (table) that the muscle tissues swelled during the winter, the greatest increase in the water content (9 to 12%) occurring in the first 3 months. The water content increased 15 to 19% over the period of winter starvation as a whole. The muscles of small individuals swelled more than those of large ones. Genetic differences were also manifested: the muscles of mirror carp fingerlings of both weight groups swelled more than those of the scaled carp.
