“…Thus, the characterization of patterns of the ovarian development might only be possible within smaller taxonomic groups, such as families. This is supported by the wide variation (3-6) in the number of ovarian stages in Brachyura (Adiyodi and Adiyodi 1972;Haefner 1976Haefner , 1977Erdman and Blake 1988;Mourente et al 1994;Hasek and Felder 2005;Castiglioni et al 2007;Rotllant et al 2007).…”

“…In this study, the hemocytes of C. danae do not invade atretic follicles and the chemical composition of secretion vesicles of hemocytes consists of glycoproteins with neutral polysaccharides and lack acidic polysaccharides. Most studies on the accumulation of nutrients in the ovary are associated with the progressive increase in GSI, lipids and ⁄ or proteins in shrimps (Mourente and Rodrigues 1991;Spaargaren and Haefner 1994;Cavalli et al 2001;Wouters et al 2001) and crabs (Mourente et al 1994;Hasek and Felder 2005).

Zara, F.J., Gaeta, H.H., Costa, T.M., Toyama, M.H. and Caetano, F.H. 2011. The ovarian cycle histochemistry and its relationship with hepatopancreas weight in the blue crab Callinectes danae (Crustacea: Portunidae). —Acta Zoologica (Stockholm) 00:1–13. Several studies use macroscopic patterns of the ovarian development in crustaceans. Here, we examined the relationship between ovary histochemistry, changes in gonadosomatic and hepatosomatic indices against the macroscopic pattern of the ovarian development in Callinectes danae. Animals were collected in the south coast of São Paulo State, Brazil. Ovaries were macroscopically classified as juvenile, rudimentary, developing, intermediary, mature, and rudimentary ovigerous. Samples were fixed in 4% paraformaldehyde, processed for historesin, and stained with HE, protein, and neutral and acid polysaccharides detection. The juvenile oocytes are not enclosed by follicular cells and have fewer yolk nuclei being less intense in PAS reactivity than rudimentary oocytes. Developing oocytes show yolk granules and thick follicular cells. Yolk granules were positive for proteins and neutral polysaccharides. The intermediary stage is marked by a qualitative increase in yolk granules and the onset of chorion formation. In mature oocytes, cytoplasm is completely filled by yolk granules and the chorion is completely formed. Ovigerous ovaries have several atretic follicles and large quantities of hemocytes in the process of tissue reorganization. In C. danae, the changes in cell, goandosomatic and hepatosomatic indices coinciding with macroscopic observations and any combination of different macroscopic stages in a single pattern should be avoided.

“…The range for Uca in the present study is slightly higher than the range of 23 to 30% DW of two grapsoid crabs, Armases cinereum (Bosc) and Sesarma nr. reticulatum (Say), from Louisiana (Hasek and Felder, 2005). Thus, these values range widely among the few taxa examined to date and do not suggest a pattern that can be readily correlated to phylogeny or habitat.…”

Precocity has been observed in fishes and crustaceans. However, mechanisms underlying precocity have not been well documented in crustaceans and are thought to be influenced by both genetic and environmental factors. Also, precocity is generally considered to have negative effects on crustaceans. The Chinese mitten crab Eriocheir sinensis, a catadromous species endemic to China, is a high valued commodity and in the recent past is being extensively cultured to meet the growing demand by the restaurant trade. The mitten crab is an ideal candidate for precocity studies because of their large size, distinct secondary sex characters, wide distribution and abundant availability from commercial farms. In this article, progress in several aspects of precocity of E. sinensis is reviewed, including the phenomena of precocity and its effect, identification of precocious crabs, factors related to precocity (temperature, salinity, light, nutrition, stocking density, and germplasm), relationships between precocity and neuro-endocrine system, steroid hormones or hepatopancreas, prevention and control methods of precocity. In addition, possible future directions for the study of precocity are suggested.
