“…According to RUFFINO et al (1994), the abrasion while the animal moves around or ventilates, and the volumetric expansion of the eggs due to imbibitions of water at the initial and terminal periods of incubation, also explained these differences in the number of eggs for the different sizes of females. BALSUNDARAN & PANDIAN (1982) related that Decapoda species lose up to 43% of eggs exposed on pleopods.Armases rubripes presented a reduced fecundity rate compared to other species of Grapsoidea (Tab. II), but presented higher rate compared to the fecundity obtained in the seven mangroves of São Paulo (CASTIGLIONI et al, 2004).…”

Iheringia, Sér. Zool., Porto Alegre, 96(1):47-52, 30 de março de 2006 Reproductive biology of the sesarmid crab Armases rubripes (Decapoda, Brachyura)... ABSTRACT. The aim of this work was to gain knowledge about reproductive biology of the crab Armases rubripes (Rathbun, 1897) from an estuarine area of the Sepetiba Bay. Samples were taken monthly from February 2003 to January 2004 in the Sahy River estuary (22º56'S; 44º01'W), Rio de Janeiro, Brazil. The crabs were collected by hand during 15-minute catch-effort sessions conducted by two people. In the laboratory, the specimens were separated by sex, carapace width was measured and gonadal stage was checked macroscopically. A total of 830 individuals were caught -304 males, 373 females (60 ovigerous females) and 153 juveniles. The ovigerous females were found almost year-round, except in November and April, showing a continuous reproductive period. They presented a size range from 8.2 to 15.0 mm carapace width (12.1 ± 1.7 mm). Color and macroscopical aspects determined five gonadal stages for males and females (immature, rudimentary, intermediary, developed and resting). First sexual maturity was estimated at 6.5 mm of carapace width for males and 8.1 mm for females. Individual fecundity varied from 200 to 11,460 eggs (4,458 ± 2,739 eggs). Mean egg size was 0.248 ± 0.026 mm, varying from 0.213 to 0.333 mm, while the volume ranged from 0.0051 to 0.0188 mm 3 (0.0082 ± 0.0029 mm 3 ). Reproductive biology of the sesarmid crab KEYWORDS.Crab, Sesarmidae, fecundity, reproduction, sexual maturity. Crustaceans exhibit various patterns of life history and reproductive strategies, mainly when habitat is considered. According to MANTELATTO & FRANSOZO (1997), fecundity is an important parameter in determining the reproductive potential of a crustacean species and/or of stock size of a population. GONZÁLEZ-GURRIARÁN & FREIRE (1985) related the importance of sexual maturity for estimating the puberty molt for the examination of external morphological modifications and gonads development.The sesarmid crab Armases rubripes (Rathbun, 1897) is a tropical and subtropical species usually found in salt marshes and estuaries of Central and South America (CAPÍTOLI et al., 1977), widely distributed from Nicaragua to Rio de la Plata, between Uruguay and Argentina (MELO, 1996).According to CAPÍTOLI et al. (1977), FISCHER et al. (1997) and TEIXEIRA & SÁ (1998), these small crabs feed on vegetable debris, mainly roots and stems of Spartina sp. (Poaceae), living inside self-built burrows in muddy substrates or between bromeliad axils. Aspects concerning to biology of this species are restricted to a few studies. CAPÍTOLI et al. (1977) studied this species in the estuarine region of Lagoa dos Patos, Rio Grande do Sul (Brazil); FISCHER et al. (1997) As a contribution to the knowledge of this crustacean, some aspects of the reproductive biology of A. rubripes from an estuarine area were examined (e.g. sexual maturity, breeding period, molting, fecundity and eggs size). After their collectio...

“…Numerous sources of embryonic mortality are documented for brachyuran crabs, acting either at oviposition, during embryogenesis or at hatching (Kuris 1990). Among others, eggs can fail to attach to female pleopods (Choy 1988), detach due to mechanical stress (Kuhn et al 2011) or die during incubation due to adverse external conditions such as nitrite concentration development in culture systems, poor oxygen availability, unsuitable salinities and temperatures, embryo predation, viral, bacterial and fungal diseases, epibionts and parasites (Balasundaram and Pandian 1982, Harper and Talbot 1984. Also, mortality may be the result of unsuccessful fertilization of some eggs of a clutch (Choy 1988).…”

Summary:The embryogenesis of Ovalipes trimaculatus, a member of the highly valued portunid swimming crabs, was studied under nearly constant temperature (13±1°C), salinity (33) and photoperiod (14 h light:10 h dark) conditions. A five-stage scale of embryonic development was defined for the species. Time required to complete development averaged 35.7±2.11 days, showing no significant differences between embryos located in inner, middle and outer portions of the egg mass. The egg chorion was rounded and showed the highest growth in diameter between stages I (morula-blastula-gastrula) and II (primordium of larval structure) and between stages III (appendage formation) and IV (eye formation). Results reported here provide a baseline for optimizing hatchery operations and useful information for management purposes.Keywords: crustacean; crabs, aquaculture; Ovalipes trimaculatus; embryology.Desarrollo embrionario del cangrejo nadador Ovalipes trimaculatus (Decapoda: Brachyura: Portunoidea) Resumen: Se estudió la embriogénesis del cangrejo nadador Ovalipes trimaculatus, miembro de la familia de portúnidos altamente valorados, bajo condiciones constantes de temperatura (13±1°C), salinidad (33) y fotoperíodo (luz 14h:10h oscuridad). Se definió una escala de cinco etapas de desarrollo embrionario para la especie. El tiempo necesario para completar el desarrollo es de 35.7±2.11 días, sin mostrar diferencias significativas entre embriones ubicados en porciones interior, media y exterior de la masa de huevos. Los huevos son esféricos y presentan mayor crecimiento en diámetro entre las etapas I (mórula -blástula -gástrula) y II (primordio de estructuras larvarias) y entre las etapas III (formación de apéndices) y IV (formación de los ojos). Los resultados aquí presentados proporcionan la base para la optimización del cultivo y brindan información útil para el manejo de la especie.Palabras clave: crustáceos; cangrejos; acuicultura; Ovalipes trimaculatus; embriología.Citation/Como citar este artículo: Martelli A., Tapella F., González-Pisani X., Dellatorre F., Barón P.J. 2016.

“…Brood loss is a well-known phenomenon in decapods (for review: Kuris, 1991) and may vary in caridean freshwater shrimps between 23% (Anger & Moreira, 1998) and 53% (Balasundaram & Pandian, 1982). Information of egg mortality during embryogenesis in Atyidae is extremely limited.…”

ABSTRACT. The caridean freshwater shrimp Atya scabra is a common resident of stream systems of tropical rainforests in America, including Brazilian drainages. This shrimp has an amphidromous life cycle, which increases its vulnerability when facing habitat fragmentation. Since information on the reproduction of this species is still limited, we present here data on egg production, egg loss, and energy investment, to achieve a better understanding of reproductive features of A. scabra. Specimens were collected between 2006 and 2007 in São Sebastião Island, southeastern Brazil, in 13 locations. The fecundity of 21 ovigerous females analyzed ranged between 414 and 19,250 eggs, which were higher than previously reported. However, the larger size of females analyzed may explain the observed intraspecific difference in egg production. During embryogenesis, egg volume and water content increased by 103 and 22.6%, respectively. The initial egg volume of A. scabra in the present study (0.027 mm 3 ) was slightly lower, but comparable to the values reported previously from the same study area. During incubation, females of A. scabra lost 15% of their initially produced eggs. The reproductive output (average RO of 3.6%) is the first report for any atyid species. Its value is fairly low compared to other freshwater shrimps, and it is hypothesized that this might be related to a high energy investment in morphological adaptations, which allows the shrimp to cling on to the substrate in the fast flowing environment they inhabit. Additionally, the long life span, a well-known phenomenon in atyid shrimp, may allow the species to invest a relatively low amount of energy per brood in egg production, but over a longer time span.

El camarón carídeo de agua dulce, Atya scabra, es un residente común del sistema de arroyos de los bosques tropicales de América, incluyendo drenajes brasileños. Este camarón tiene un ciclo de vida anfídromo, lo que aumenta su vulnerabilidad al enfrentar la fragmentación del hábitat. Dado que la información sobre la reproducción de esta especie es todavía limitada, se presentan datos sobre producción de huevos, pérdida de huevos e inversión energética, para lograr una mejor comprensión de los aspectos reproductivos de A. scabra. Los especímenes fueron recolectados entre 2006 y 2007 en la isla São Sebastião, al sureste de Brasil, en 13 localidades. La fecundidad de las 21 hembras ovígeras analizadas varió entre 414 y 19,250 huevos, valores que son más altos que los reportados previamente, sin embargo, el mayor tamaño de las hembras analizadas podría explicar la diferencia intraespecífica en la producción de huevos. Durante la embriogénesis, el volumen del huevo y el contenido de agua aumentó en 103 y 22,6%, respectivamente. El volumen inicial del huevo de A...
