Аннотация:Gonadal differentiation and development of sex cells are described in the tropical representative
of the family Mullidae, manybar goatfish Parupeneus multifasciatus, using histological methods and observa
tions of oocytes in vivo. Anatomical differentiation of the gonads is registered by approximately 5 cm fork
length (FL) and 1.5 g body weight of the fish, and cytological differentiation (in the females) occurs by
approximately 6 cm body length and 2.6 g body weight. In the ovaries of sexually mature females before
spawning, oocytes of all phases and periods of development can be found. Based on the gonadal structure and
frequency distribution of oocyte diameter, the type of oogenesis is continuous.
