Crassostrea rhizophorae (Guilding, 1828) is one of the tropical species of oysters cultivated on the Brazilian shore. Despite its high commercial value, there is no information on the gonadal characteristics during the reproductive stages of this species. The objective of this work was to analyze the morphology and morphometry of Crassostrea rhizophorae oocytes and follicles in three stages of the gonadal cycle. Were analized histological sections of gonads considering that the oocytes presented visible nuclei and nucleoli, it was observed three gonadal cycle stages: early gametogenesis, growth and maturation. In the early gametogenesis stage, follicles and oocytes presented diameters of 180.29 (± 41.91) and 18.66 (± 6.85) µm, respectively, and presence of...
