Descripción histológica de la oogénesis y espermatogénesis del camarón de cultivo, Litopenaeus vannamei

Abstract: Descripción histológica de la oogénesis y espermatogénesis del camarón de cultivo, Litopenaeus vannameiAdvanced spermatids and spermatozoa were only observed in the vasa deferentia; this finding appears not to be universal in Penaeidae. Key words: Penaeidae, spermatogenesis, oogenesis, Litopenaeus vannameiResumen.-Esta investigación describe las fases detalladas de la oogénesis y la espermatogénesis, a nivel histológico, del camarón blanco del Pacífico americano, Litopenaeus vannamei. Ambos procesos fueron est… Show more

“…Development of oocytes seemed normal in DTA-AG implanted females. The oocytes seemed previtelogenic in an early perinucleolus phase (Alfaro-Montoya, 2013). Therefore, AG implantation did not induce any measurable effect on gonad development during the 2-3 months of experimentation.…”

“…Spermatogenesis was altered in andrectomized males as indicated by histological evidence. In normal males, spermatogenesis advances in seminiferous tubules to mid spermatid stage; advanced spermatids and spermatozoa are only observed in vasa deferentia (Alfaro‐Montoya ). These alterations are associated with the integrity of spermatids and the normal structure of seminiferous ducts, particularly with the integrity of the epithelial layer, generating reproductive tissue abnormalities that can reach macroscopic dimensions characterized by white spherical nodules (Fig.…”

“…Gonadic development associated with the reproductive cycle of aquatic organisms is often established using macroscopic scales of sexual maturity, gonadic indices and condition factor, which frequently do not agree with the dynamics and gonadal functioning cycle (Palacios et al, 1999;Peixoto et al, 2003;Feitosa-Silva & Da Cruz-Landim, 2006;Castiglioni et al, 2007). In some crustacean decapods, such as prawn and shrimp, ovarian development can be visualized by shining a light through the transparent carapace of the animal (Ceballos-Vázquez et al, 2003;Bembe, 2009;Alfaro-Montoya, 2013), but in many crab species, including L. santolla, the carapace is opaque, and this technique cannot be used.…”
