This present investigation was designed to describe structure and ultra structure of ovaries of Sompat grunt Pomadasys jubelini. Sampling were done monthly in Grand-Lahou, Ebrie and Aby lagoons (Côte d’Ivoire) from January 2007 to December 2008. Histological Techniques were made using the paraffin method. Ovaries of sompat gunt are consisting of two contiguous lobes. Six stages of maturity were observed. The ovaries display a variety of colours from transparent or pink to pale yellow, orange and reddish. Ultrastructure observation showed two types of ovaries. An ovarian differentiation divided into four stages observed in fish who fork length is from 10.70 to 30.90 cm, and an undifferentiated gonads divided into two stages observed in fish who fork length is from 8.50 to 25.60 cm. Undifferentiated gonads were characterized by many primary oogonia and young oocytes. Cells are previtellogenic oocytes. Differentiated ovaries are characterized by heterogeneous cytoplasm with some vacuoles and vitellus.
