“…Soon after delivery of the preceding brood (day 0), oocyte diameter rapidly increased to 1.4 mm, indicating that vitellogenesis became active. Similar patterns of growth in vitellogenic oocytes have been described for other poeciliids such as Xiphophorus helleri , 2 Poecilia latipinna , 10,11 and P. reticulata . 12 From day 0 to 5, the larger diameter group (forming the secondary peak in Fig.…”

“…These secretory granules are few in number and small in size in the post-spawning season, while they become numerous and larger in both prespawning and spawning seasons. These results are in accordance with those of Peute et al (1978) in Salmo gairdneri, Ueda and Takahashi, (1980) and Ueda (1981) in Misgurnus anguillicaudatus and Young and Ball (1982) in Poecilia latipinna. Furthermore, during the post-spawning season, the basophils (B1) of L. carinata are characterized by the presence of numerous vacuoles that containing fibrillar inclusions.…”

“…In immature males, the differentiation of TSH cells in the absence of GnRH-Rs suggests that GnRH might be important for release rather than synthesis of TSH hormone. On the other hand, in mature males, the activation of GnRH-Rs in TSH cells could have some role in gonadal maturation because thyroid hormones and TSH cells have been implicated in reproductive processes (37).…”
