Variations in serum constituents of the blue crab, Callinectes sapidus: Major cations

Osmotic and Ionic Regulation in Several Western Atlantic Callianassidae (Crustacea, Decapoda, Thalassinidea)

“…Limited (Colvocoresses, Lynch, and Webb, 1974) and such observations seem compatible with data indicating that the sodium transport system ultimately establishes the blood osmolality (Shaw, 1960). By day 9 after direct transfers, blood sodium/ chloride ratios in C. jauiaicensc are higher at 3 ( /< f than at 37 r /c salinity.…”

Sodium and glucose transport across the in vitro perfused midgut of the blue crab, Callinectes sapidus Rathbun

“…These results are in accord with Gerald & Gilles (1973), although the medium potassium concentration that they used never exceeded 10 mM. In high salinity waters, Gifford (1962), Colvocoresses et al (1974) and Findley & Stickle (1978) found lower potassium concentration in the hemolymph than the medium.…”

“…Such a pattern of chloride regulation has Sal ini ty (0/00) been observed previously (Odum, 1953;Gerald & Gilles, 1972;Findley & Stickle, 1978). Sodium and chloride concentrations determined in the present study are within the range of published data on animals collected in the field without prior acclimation (Gifford, 1962;Colvocoresses et al, 1974).…”

“…A-5 and 6). The levels of these two cations are within the range reported in field study by Colvocoresses et al (1974), who also showed hyperionic magnesium regulation below 6-8 0100 S, which is beyond the range of the present study. It is noted that serum magnesium concentration in C. sapidus was usually less than 50% of that in the medium.…”

Acid-Base Balance in Callinectes Sapidus During Acclimation from High to Low Salinity

“…In animals acclimated to 865 m-osmol (426 mM-Na + and 489 mM-Cl~) the blood Na + concentration was 443 ± 2 mM and Cl~ was 449 ± 4 mM. The Na + values are similar to those reported by Colvocoresses, Lynch & Webb (1974) for acute measurements on blue crabs taken from similar salinities (415 and 364 mM-Na+ at 870 and 270 m-osmol, respectively). Our Cl~ concentrations were higher at the high salinity (449 v. 368 mM) but agree for crabs at approximately the same low salinity (338 v. 327 mM).…”
