“…The ovarian development has been investigated based on macroscopic changes in color and size to determine the onset of physiological sexual maturity in natural decapod populations (López et al, 1997;Pinheiro and Fransozo, 1998;López-Greco and Rodríguez, 1999;Santos and Negreiros-Fransozo, 1999;Swiney and Shirley, 2001;Flores et al, 2002;Castiglioni and Negreiros-Fransozo, 2006). The oogenesis process and the ovarian cycle have also been described microscopically, mainly for species of economic importance belonging to the Penaeoidea (Rodríguez, 1981;Tan-Fermin and Pudadera, 1989;Quinitio and Millamena, 1992;Quintero and Gracia, 1998;Palacios et al, 1999;Sakaji et al, 2000;Sakaji, 2001;Dumont and D'Incao, 2004), Caridea (Moraes, 1995;Mossolin and Bueno, 2002), Astacidea (Ando and Makioka, 1998;Silva-Castiglioni et al, 2006;Vazquez et al, 2008) and Brachyura (Wenner et al, 1987;Minagawa, et al, 1993;Ando and Makioka, 1999;Castiglioni et al, 2007;Rotllant et al, 2007). There is no available information on these subjects for shrimps of Stenopodidea.…”
