The effect of salinity on the osmo-ionic regulation of Macrobrachium carcinus (Linnaeus)

Adaptive Osmotic Responses of Macrobrachium Acanthurus (Wiegmann) and Macrobrachium Carcinus (Linnaeus) (Decapoda, Palaemonidae) From the Southern Gulf of Mexico

“…This kind of response has not been reported for other species of the genus Macrobrachium. However, Mantel & Farmer (1983) reported a similar behaviour for the crabs, Callinectes sapidus Rathbun, 1896 and Cancer magister Dana, 1852, andMoreira et al (1988) registered that M. carcinus is a hyperregulator at low salinities and a hypoconformer at high salinities. Analysis of the results reported in Moreira et al (1988) concerning high salinity levels, showed HOC values parallel and near to the isosmotic lines, which is the tendency observed in the present study.…”

“…The isosmotic point found for Macrobrachium carcinus (490 mOsm kg −1 at 17 psu), is near the value given by Moreira et al (1988) for the same species (480 mOsm kg −1 ), while the isosmotic point obtained for M. acanthurus (632 mOsm kg −1 ), is near the values obtained for M. ohione (Smith, 1874) (643 mOsm kg −1 ) (Castille & Lawrence, 1981), M. heterochirus (647 mOsm kg −1 ), and M. olfersii (620 mOsm kg −1 ) (Moreira et al, 1983). This divergence of the isosmotic point may reflect differential adaptation to habitats with salinity fluctuations (Staton & Felder, 1992).…”

Interactions of different sodium and potassium concentrations onMacrobrachium rosenbergii(de Man) offspring quality parameters

“…With increasing water salinity, sodium and potassium concentrations, haemolymph in M. rosenbergii (Wilder et al . ) and M. carcinus (Moreira, Ngan, Moreira & Shumway ) increases slightly depending on environmental salinity. This is a critical issue affecting numerous different physiological activities and their quality in larvae.…”

Osmolality and ion balance in giant river prawn Macrobrachium rosenbergii subjected to changes in salinity: role of sex

“…1987). Species such as M. acanthurus , M. heterochirus , M. potiuna and M. carcinus and M. rosenbergii exhibit a strong ability to hyper‐regulate in freshwater and at low salinities, but become hypo‐conformers at higher salinities (Singh 1980; Moreira, Ngan, Moreira & Shumway 1988). Macrobrachium australiense and M. roesnbergii juveniles maintain hyper‐regulation over a wide range of external media from 0 to 25‰ and from 0 to 30‰ respectively (Denne 1968; Castille & Lawrence 1981).…”
