(A) Variation in gonadosomatic ratio (GSR) over the months (F = 24.885, p <0.001), (B) variation in the number of mature oocytes in each month (F = 6.746, p <0.001) and (C) plot of germ cells proportion monthly, indicating that they are more able to reproduce from October to March.

Fig. 6. Annual reproductive cycle of female April/2010 (A) to March/2011 (L), stained with toluidine blue-borax, in which ovarian development was seen more frequently from May to September, the stage of able to spawn from October to March and the stage regression from February to April. The regeneration step was not observed in females. Early oocytes (Eo), pre-vitellogenic oocytes (Pvo), vitellogenic oocytes (Vo), mature oocytes (Mo), post-ovulatory complexes (POC) and atresias (As).

Fig. 3. In the ovaries, stained with toluidine blue-borax, (A) there is the gonoduct, as indicated by the arrow; (B) the germinal epithelium, which presents: somatic cells that stand out of the germinal epithelium and will be the pre-follicular cells (Pf) to accompany the nest of oogonia (circle); (C) some oogonia begin the process of differentiation through meiosis, forming early oocytes (Eo) that stand out from the nest being involved in pre-follicular cells (Pf) characterizing the initial ovarian follicle (black circle), after then other cells come around forming the internal theca (It) and external theca (Et), forming the follicular complex (white circle); (D) the oocyte gives rise to a new stage of growth, the pre-vitellogenic one with the arising of nüages (Ng), multiple nucleoli (No) and the Balbiani corpuscles (Bc); (E) it is possible to observe the anterior structures in greater detail and also the layers of the follicular envelope, which comprises the components of theca (T), a layer of follicular cells (Fc), the basal membrane (Bm) and a pellucid zone (Pz); (F) this zone is composed by small microvilli (Mv) that protrude on the surface of the oocyte and follicular cells.

Fig. 1. In the testes, stained with toluidine blue-borax, (A) the germinal compartment is digitiform ending in blind bottom and the genesis of the germ cells follows from the distal portion of the lobes to the lumen, as indicated by lines drawn and the arrow, respectively; (B) the interstitial compartment contains blood vessels (Bv), myoid cells (Md), connective tissue (Ct) and Leydig cells (Ld); (C) there are spermatogonia that begin the genesis and form cysts (circle) organized by the Sertoli cells (B - St); (D) this gives rise to the primary spermatocytes (white circle), and then the secondary spermatocytes (black circle); (E) so occurs the formation of the spermatids (circle); (F) and the cysts break to release the spermatozoa (Sz).
