Resumo: | The present work presents of the macroscopic characterization of the female reproductive system of the penaeid shrimp Farfantepenaeus subtilis, as well the histological and histochemical description of the ovarian components in different maturation stages, and the oviduct. The female reproductive system of this species is formed by ovary, oviduct and telycum. The ovary is symmetrical, with one pair of anterior lobes, seven lateral pairs and one pair of posterior ones. The lateral lobes involve the digestive gland, except the seventh, that is directed towards the abdomen. The sixth pair is linked to the oviduct. The thelycum is closed and was considered a reproductive structure. It has lateral plates with elevations at the edge of the medium line. Analysis by the scanning electronic microscopy evidenced the presence of setae in the entire surface of it, mainly in the area of the referred edges. Histological analysis allowed identifying the organization of somatic and germinative components in units denominated nodules or cysts. The somatic components are: collagen fibers, fibroblasts, blood vessels and nurse cells. The collagen fibers presented a wavy aspect with fibroblasts among them. The blood vessels are formed by epithelial tissue and were found among the cysts. The nurse cells were found, agglomerated or not, around the germinative cells and presented cuboid or flat aspect, depending of the stage of maturation of the cell. The stages of the germinative cells lineage were described as: oogonia, initial previtellogenic oocytes, final previtelogenic oocytes, vitelogenic oocytes and ripe oocytes. These cellular types showed typical characteristics at the different maturation stages. The histochemical analysis evidenced changes in the citoplasmatic components as the cells ripen. The xii oviduct was shown to be a secretory structure constituted externally by a layer of smooth muscle fibers and under it a layer of simple columnar epithelium, which presents invaginations towards the lumen. |
