Summary
Callianassa, an estuarine animal, can experience changes in salinity which reduce the level of divalent cations in the blood, as well as changes in temperature and variations in protein concentration in the hemolymph. The hemocyanin in whole hemolymph shows evidence of dissociation (∼ 12%) after 3 days acclimation to 40% seawater. Using purified hemocyanin the dissociation from 39 S to 17 S hemocyanin was investigated for the three variables, salinity, temperature and protein concentration. An equation was developed to define the amount of dissociation which should be observed under physiological conditions.
