Ovarian development of fishes involves significant functional and structural changes during the process of mature egg formation. In this study, we report the folliculogenesis and follicular growth in the endangered species Brycon opalinus as well as the dynamics of the proteins Foxl2, Col4 and MMP-9 during ovarian maturation.
