摘要：

1. Survival of Penaeus chinensis juveniles (0.92 +/- 0.11 g) acclimated from 32 ppt seawater to 0 and 30 ppt seawater in 5 ppt intervals per day was 0 and 100% after 12 and 14 days, respectively. 2. Survival was 75, 88 and 76% for the shrimps reared in 20, 25 and 30 ppt after 60 days. 3. Molting frequency was lowest for the shrimps reared at 20 ppt, and highest for those reared at 5 and 40 ppt. 4. Hemolymph osmolality had a linear relationship (slope = 0.189) with external osmolality over the salinity range of 5 and 40 ppt. 5. The isosmotic point was 480 mOsm/kg which is equivalent to 16.5 ppt. 6. P. chinensis juveniles in the isosmotic environment or slightly higher grew the best, those in the hyperosmotic environment the second, and those in the hypoosmotic environment grew the worst.
