Abstract
The effect of bilateral eyestalk ligation or ablation on the blood Na+ and ca++ concentrations of the euryhaline blue crab, Callinectes sapidus, was measured in 10 o/oo and 5 o/oo sea water. The ablations caused a significant decrease in the blood Na+ and ca++ over a 24 hour period. The serum Na+ level increased significantly 6 hours following injections of an eyestalk extract whereas the blood total ca++ level did not change significantly. Eyestalk ligation, however, did not cause significant blood Na+ and ca++ changes. The blood Na+ level of intact crabs increased significantly in acclimating to colder water when compared to eyestalk-ablated crabs.
