Abstract: Abstract: The Sillago sihama was widely distributed in the sea area of China. In recent years, researchers studied artificial breeding of sillagio sihama . Salinity was one of important environmental factor influenced the survival and growth of aquatic animals, the young of Sillago sihama（all length 23.47±0.66 mm, shell height 91.71±7.96 mg）were selected indoor to examine effects of salinity on the survival and growth of young of Sillago sihama in controlled environment, which determined young of Sillago sihama salinity adaption, it provided the scientific basis for artificial breeding of sillagio sihama. All animals were equally divided into 18 groups under different culture salinity: 0、2、4、7、10、13、16、19、22、25、28、31、34、37、40、43、46、49. Results showed that young of Sillago sihama could survival at 0 for 34h; When the salinity was 2,the survival rate, total length daily growth rate ,weight daily growth rate of the young of Sillago sihama was 86.7%,207.67μm.d-1 and 2.63mg.d-1, respectively; When the salinity was 49,the survival rate, total length daily growth rate ,weight daily growth rate of the young of Sillago sihama was 66.3%, 64.68μm.d-1and 1.13mg.d-1, respectively. The appropriate survival salinity of young of Sillago sihama was among 1.4~45.1. The optimal salinity survival was 2~43; and appropriate growth salinity was 1.6~40.2, the optimal growth salinity was 2.0~7.0. According to the experimental results conclude that sillagio sihama could adapt to a wide range of salinity , It seemingly more beneficial to the growth of the young of Sillago sihama under low salinity.
