【Abstract】 In this paper the effects of salinity on embryonic and larval development of Pollicipes mitella are reported. When water temperature is held at 25±1℃, the optimum salinity range for the development of embryonic is 15 33～41 78 .The best rate of hatching and fastest development of embryonic is 21 38～28 55.The upper limit and the lower limit of salinity for the development of larval are 41 78 and 21 38.The best survival and fastest development of larval is 28 55～35 16.更多还原
