“…The high and low values of 96-h LS^o in stage I juvenile 5. serralum were 59 and 13, respectively (Charmantier and Channantier-Daures 1994). The values of 21-day LS-jo in the blue crab Callinectes similis Williams, 1966 were 60.8 and 2.6 at high and low salinity ranges, respectively (Guerin and Stickle, 1997b). The high salinity tolerance of H. crassicomis is consistent with the results from studies on various members ofthe same superfamily Talitroidea.…”

“…For instance, dry weight of the blue crab Callinectes similis juveniles reared at a salinity of 5 was half of those reared at 10 (Guerin and Stickle 1997b). In this study, we found that the optimal salinity for growth of H. crassicomis juveniles is 20 at 25 C. The phenomenon can be explained by the physiological relationship between salinity and metabolism.…”

This study explored the survival and growth of the marine amphipod Hyaie crassicomis under different conditions of ambient temperature and salinity in the laboratory. In 96-h exposure experiments at a salinity of 30, //. crassicamis tolerated temperatures between 6 and 28 C C>90% survival). The 96-h LT50 value (median lethal temperature) at high temperature range for the amphipod was 32 C. The values at low temperature range for adults and juveniles were 3.2 and 4.2 C, respectiveiy, indicating that adults have a higher tolerance to low temperature than juveniles. At 25 C, the amphipods tolerated salinities between 10 and 50 (with >80% survival in 96 h). The 96-h LS^o values at high and low sahnity ranges were 56 and 2, respectively. Growth of the juveniles ft'om instars 1 to 6 was determined under different combinations of temperature and salinity. Growth rate of juveniles culrured at 25 C and a salinity-of 20 was the highest (0.114 mm day ') among the combinations of 15-25 C and 10-40 salinity. The moult increment of body length was afFected by both temperature and salinity. Yet the intermoult duration ofthe amphipods was affected by temperature only but not by salinity.

“…In the present study, an ontogenetic migration of C. danae can be proposed. The juvenile crabs migrate to estuarine areas, where they are protected from predation pressure that is usually higher in open seas and additionally the abundance of shelter and food is available in this environment, as suggested by Hines et al (1987) and Guerin and Stickle (1997). After development, adult and ovigerous females migrate to the lower estuary and the open sea.…”

This paper aims at describing the population ecology of the swimming crab Callinectes danae Smith, 1869 in one of the most productive estuaries of Brazil, the Santa Cruz Channel. These crabs were monthly collected from January to December/2009 at four stations along the channel, two in the upper and two in the lower estuary. A total of 2373 specimens of C. danae were collected during the study. Males had a larger average carapace width than non-ovigerous females (60.0 ± 15.6 mm and 52.9 ± 12.4 mm, respectively), an adaptation that gives greater protection for females during the copulation. Overall sex ratio did not differ significantly from 1:1. However, evaluating sex-ratio by sampling area, males and juveniles of both sexes occurred preferentially in the upper estuary (p < 0.05), while adult females, including ovigerous, inhabited the lower estuary, an area of major marine influence (p < 0.05). While juveniles look for estuarine waters due to the benefit from the shelter and abundance of food, ovigerous females migrate to areas of greater depth and higher salinity in order to provide a more favorable environment for embryonic and larval development and to enhance larval dispersal. Recruitment of juveniles was continuous along the year, but intensified from March to June and, with less intensity, from October to December

“…Under laboratory conditions, an increase in mortality rate was observed for Callinectes sapidus Rathbun, 1896 with a decrease in temperature and salinity (Rome et al, 2005). Salinity was found to be favorable to the abundance of Callinectes bellicosus Stimpson, 1859 in a coastal lake in Mexico (ArreolaLizárraga et al, 2003); Callinectes simillis Williams, 1966 exhibits a better growth rate in high salinity (Guerin & Stickle, 1997). Róman-Contreras (1986) found that the entrance of C. sapidus, C. danae and C. ornatus in Términos Lake (México) tended to be greater when salinity increased.…”
