Abstract

Ultimobranchial gland (UBG) in non-mammals are rich source of calcitonin (CT) which induce hypocalcemia in mammals. In fishes the CT recorded higher levels during ovarian development suggesting a specific role of CT in the sexual maturation of female fishes (Fouchereau-Peron et al., 1990). Histological changes in UBG and gonads of Cyprinus (both sexes) were studied in relation to sexual maturation, serum calcium (Ca) and inorganic phosphate (Pi) levels.
