The article researches fatness of grey mullets during their reproductive cycle. It was established that in spring fat depot is practically absent in grey mullets body-cavity. In summer accumulation of energy substances takes place. In August most of the examined fish had fatness of 2-3 points, but in September the number of fish with minimal fatness increases. Large content of fat in the body-cavity of grey mullets (female) is found in the prime of ovogenesis. In the IV stage of ma-turity, when intensive trophoplasmic growth of acolytes takes place, fatness sharply decreases and grey mullets come to the prespawning period practically with waste fat depot. Accumulation of lipids in muscular tissue of grey mullets as against fat depot in body-cavity takes place independently of maturation of ovary.
