Abstract：To explore the mechanism underlining the adaptation of Schizothoracine species to the plateau hypoxia,we measured and compared the concentrations of 11 elements of the blood cells and plasma of two Schizothoracine fish species inhabiting high altitude,Gymnocypris scleracanthus(4 580 m)and Oxy gymnocypris stewartia(3 650 m)and one inhabiting low altitude,Schizothorax prenanti(650 m),with inductively coupled plasma mass spectrometry(ICP-MS)method.In blood cells,elements Cr,Mg and Cu were different in concentration among three fish species.In the plasma,elements K and P of fish species inhabiting low altitude(S.prenanti)were significantly higher than those of two spe-cies inhabiting high altitude,and element Na of S.prenanti was significantly lower than that of fish species inhabiting high altitude.To adapt the low temperature and hypoxia at high altitude,Schizotho-racine may have adjusted their body metabolism by regulating the content of elements in their body.Our findings provided a new insight into the plateau hypoxia adaptation of Schizothoracine fish species.
