P. monodon was found to be a stronger osmotic and ionic regulator than P. pencillatus. The juveniles of both species are stronger osmoregulators than adults. The salinity ranges over which osmoregulations were performed efficiently were 3-50 ppt for juvenile P. monodon, 15-50 ppt for adult P. monodon, 5-30 ppt for juvenile P. penicillatus and 15-30 ppt for adult P. penicillatus. The isosmotic points were 730, 750, 747 and 800 mOsm/kg, respectively. The curves of sodium, chloride and potassium corresponded to those for the osmotic concentration of adults. The respective isoionic points for P. monodon and P. penicillatus were 352 mEq/1, 348 mEq/1 for sodium; 320 mEq/1, 304 mEq/1 for chloride; and 7.1 mEq/1, 6.1 mEq/1 for potassium. Calcium was accumulated in both species, while magnesium levels were strongly reduced. P. monodon may be the strongest osmoregulator among the Penaeus species so far studied. |
