Abstract: A 40 day feeding trial was conducted to determine effects of different salinities(0,8,15,23,and 30)on growth and survival of Chinese shrimp Fenneropenaeus chinensis strain“Huanghai No.2”juveniles with body weight of 2.54 g.The results showed that the salinity had significant effects on the survival and growth in the shrimp.The shrimp was found to be survival for only 5 days when it was exposed to the water with a salinity of 0.There was different survival in the shrimp exposed to various salinities,the maximal rate of 95%at a salinity of 30,and the minimum of 81%under a salinity of 8.The best growth(daily weight gain of 0.202 g)was observed in the shrimp exposed to a salinity of 23,followed by at a salinity of 15(daily weight gain of 0.175 g),and 30(daily weight gain of 0.172 g),and the poorest growth(daily weight gain of 0.152 g)at a salinity of 8,indicating that“Huanghai No. 2”is not suitable for being cultured in freshwater.The findings approve that“Huanghai No.2”juveniles can be cultured at a salinity of over 8,the optimal of about 23.
