摘　　要：本文以长期生活在较低盐度（１２左右）河口潮间带地区的端足类日本大螯蜚所繁衍的幼体为材料，探索了盐度与幼体生存、生长和发育的相互关系。结果表明，该种钩虾的适宜盐度范围为５．３０～３０．８０，最适盐度范围为１０．１３～１４．７８。在高盐度，经过短期过渡，钩虾成活率明显增高。在适宜盐度和其它条件下，在实验室可培养出成熟的雌雄个体。The juveniles of amphipod Grandidierella japonica were collected at Hekou estuary intertidal zone where the salinity of sea water was quite low(about 12)and the effect of salinity on the juvenilesgrowth was studied.The results showed that the range of salinity was 5.30～30.58 for this species and that of 10.13～14.78 was the best.The survival rate of was obviously increased at high salinity after shortterm transitional holding from low to high salinity sea water.The sexual mature amphipods might be cultured in laboratory under adaptive salinity and other conditions.
