“…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.…”

“…There are several studies describing the morphological aspects of the gonads, such as the morphological and histochemical aspects of the gonad of Macrobrachium rosenbergii (Moraes, 1995); the histochemical aspects of the testis and vas deferens of Goniopsis cruentata (Garcia and Silva, 2006); spermatogenesis and formation of the spermatophore in the vas deferens of Chionoecetes opilio (Sainte-Marie and Sainte-Marie, 1999); morphology and histology of the male reproductive system of the mangrove land crab Ucides cordatus (Castilho et al, 2007) and the stages of the reproductive cycle and anatomical changes occurring in the spermatic cells (Bawab and El-Sherief, 1988).…”

Histological and histochemical analysis of the gonadal development of males and females of Armases rubripes (Rathbun 1897) (Crustacea, Brachyura, Sesarmidae)

The objective of this study was to provide information on the histological characteristics of the gonads of male and female Armases rubripes crabs, and to try to establish a relationship between the microscopic and macroscopic stages previously identified. Thirty-six crabs were collected by hand between February 2003 and January 2004 in banks of Spartina alterniflora on Sahy Beach in Mangaratiba, Rio de Janeiro state, Brazil. The histological analysis of the ovaries of A. rubripes demonstrated a gradual process of development of the oocytes. According to their cellular characteristics, five types of cells were distinguished: oogonia, oocyte I, oocyte II, oocyte III and oocyte IV. The ovaries showed four stages during gonadal activity: stage I (rudimentary), stage II (developing or maturing), stage III (developed or mature) and stage IV (resting). The results of the histochemical analyses showed that the ovaries vary according to the gonad development stage. The histological aspect of one section of the male gonad was always the same in all of the seminiferous tubules, where the lumen of these tubules always contained spermatozoa and/or spermatids. It was not possible to characterize the three stages of gonad development in the males. This agrees with previous reports in the literature. However, in the females there was a relationship between the gonad stages distinguished macroscopically and the results obtained through the histological and histochemical analysis, due to the presence of different cell types, as well as the lysis process and reabsorption of the oocytes in spent females.Keywords: crab, gonadal development, histochemistry, Sesarmidae.

“…STUCKI (2000) says that in Switzerland mating occurs continuously from late August to April. The process of spermatogenesis and oogenesis in Decapoda has been widely described, especially at the ultrastructure level (MORAES, 1995;YUNLONG et al, 1997, ANDO andMAKIOLA, 1998;HUANG HAXIA et al, 2001). Many papers focus on the structure and production of sperm (LI TAIWU 1995;RICHTER de FORGES et al, 1997;WANG LAN et al, 1999) and the production of spermatophores (WANG LAN et al, 1996;MAC DIARMID and BUTLER, 1999).…”

The aim of this study was to follow the gonadal development in freshwater crayfish Orconectes limosus (Rafinesque) by histological examination of ovaries and testes as well as monthly investigation of the gonadosomatic index over a period of one year. Male gonadosomatic index (I G ) ranged between 0.11 to 0.79% with a minimum in July (0.11%) and maximum in September (0.79%) while in females it ranged between 0.25 to 6.15% with a minimum in July (0.25%) and maximum in April (6.15%). Between April and May, the histological dissection indicated presence of mature oocytes and oocytes undergoing resorption. Egg extrusion took place in mid April. During the summer months, the volume of oocytes gradually decreased. In winter and spring, the volume of oocytes began to increase during preparation for egg extrusion. The size of oocytes in the ovary increased from 0.2 mm at the beginning of the reproductive cycle to 1.8 mm immediately before egg extrusion. Average number of eggs in the ovary was 140. 8 ± 51.63 (76-290). The ovary was of brown colour for the majority of the cycle, but white in June and July and orange in August and September. Mating started in October and continued through the winter. A difference was found in the proportions of testis and vas deferens in the male reproductive organ during the year. The male gonadosomatic index increased in September during preparation for mating (I G = 0.79%). During the mating season, the male spermatophores were predominantly filled with spermatozoa and sperm was also noted in the vas deferens. Two out of 15 males sampled during the winter were found to be intersex, in which atretic oogonia and oocytes were present at the periphery of testicular tissue and occupied less than 15% of testicular tissue. The evidence of intersex strongly suggested transitional stages of a gradual change of sex, which may be qualified as partial hermaphroditism. Key ÉTUDE DU CYCLE ANNUEL DE DÉVELOPPEMENT DES GONADES ET DE LEUR ULTRASTRUCTURE CHEZ L'ÉCREVISSE AMÉRICAINE (ORCONECTES LIMOSUS) RÉSUMÉLe cycle annuel de reproduction de l'écrevisse américaine (Orconectes limosus) a été décrit par l'observation externe des gonades, en enregistrant les changements de l'indice gonadosomatique (I G ), et par l'analyse histologique des organes reproductifs (ovaires et testicules). L'observation et l'analyse histologique ont été realisées mensuellement. Les valeurs suivantes de l'I G ont été trouvées : 0,11-0,79 % (mâle) et 0,25-6,15 % (femelle). La valeur minimale de l'I G pour les mâles a été observée au cours du mois de juillet (0,11 %) et la valeur maximale au cours du mois de septembre (0,79 %). Pour les femelles la valeur minimale a été observée en juillet (0,3 %) et la valeur maximale en avril (6,15 %). La formation d'ovocytes mâtures et leur désintégration ont été observées ou cours de la période avril-mai. L'expulsion d'ovocytes mâtures a été observée en avril. Le volume des ovocytes a augmenté principalement en été. Néanmoins les ovocytes ont commencé à grandir au cours de l'hiver et du...
