The present study is to evaluate the osmoregulatory ability of the lined seahorse Hippocampus erectus, a valuable species for traditional Chinese medicine. The effect of low salinity (10‰, 15‰, 20‰, 25‰, 32‰ as control) on the plasma osmotic pressure, ions concentration including Na+, K+, Ca2+ and Cl-, and Na+/K+-ATPase (NKA) activity in the gill of the juvenile seahorses was carried out within 96 h. The results show that plasma osmotic pressure and ions concentration down-regulated significantly with the decreasing salinity at 6 h to 12 h and stabilized at 12 h to 24 h after the salinity stress. The isotonic point of the juvenile seahorses was 317.13 m Osm·kg-1 after 96 h transfer, the equivalent of the salinity of 12.05‰, meanwhile, isoionic points of Na+ and Cl- were 96.48 mmol&middo..
