摘要：

The effects of salinity on hemolymph osmotic pressure, Na+ concentration and Na+-K+-ATPase activity of gill of Chinese crab Eriocheir sinensis were studied. The results showed that hemolymph osmotic pressure and Na+ concentration increased signifi- cantly (P<0.05), and the Na+-K+-ATPase activity of gills decreased significantly (P<0.05) when salinity increased from 0 to 16. The hemolymph osmotic pressure and Na+ concentration in each treatment group rose remarkably at 0.125 d or 0.25 d, while the Na+-K+-ATPase activity of gill reduced gradually with increased experiment time in 3 d. Then the three parameters remained at a constant level after 0.25 d, 0.125 d and 3 d, respectively, and higher hemolymph osmotic pressure, higher Na+ concentration and lower Na+-K+-ATPase activity of gill occurred at higher salinity. The effect of salinity change on protein concentration of hemolymph was indistinct (P>0.05); However, the protein concentration decreased gradually with the increase of salinity from 0.25 d to 1 d, and then tended to be stable from day 1 to day 15.
