研究20℃水温下，饲养在玻璃缸中天津厚蟹成体在外界环境渗透压变化时体内血淋巴渗透压的调节。结果显示，当外界盐度由30低至0时，血淋巴渗透压随之降低，但始终高于外界环境渗透压；而当外界盐度由30升至50时，血淋巴渗透压随之升高，但始终低于外界环境渗透压。盐度作用时间也影响血淋巴渗透压，盐度作用3 h后，盐度0、10、50（盐度20、30、40除外）下天津厚蟹血淋巴渗透压与作用开始时的0 h有显著差异（P＜0．05）。天津厚蟹血淋巴渗透压与介质渗透压之间的等渗点值为815．6 mmol/kg ，对应盐度为27．1。结果表明，天津厚蟹在20℃时具有较高的渗透调节能力。

The hemolymph osmotic regulation was studied in adult mudflat crab ( Helice tientsinensis ) exposed to a salinity of 0 ,10 ,20 ,30 ,40 and 50 for 9 days at 20 °C in aquarium using vapor pressure osmometer .The results showed that there was lower hemolymph osmotic pressure in the mudflat crab exposed to the salinity from 30 to 0 ,higher than that in ambient osmotic pressure .The mudflat crab exposed to the salinity from 30 to 50 had higher hemolymph osmotic pressure ,lower than that in ambient osmotic pressure .The exposure period was found to affect the hemolymph osmotic pressure .There was significant difference in hemolymph osmotic pressure at a salinity of 0 ,10 ,and 50 except 20 ,30 and 40 (P< 0 .05) between 0 h and 3 h after the experiment .The mudflat crab had isosmotic point of 815 .6 mmol/kg ,equivalent to 27 .1 for salinity concentration .The findings indicated that the mudflat crab as an osmoregulator had good regulation of osmotic pressure ability at water temperature of 20 ℃ .
