[Objective] The aim of this study was to provide theoretical basis for the large-scale breeding of Fenneropenaeus chinensis as well as the promotion of Chinese herbal medicine. [Method] The experiment was conducted to determine the effects of salinity (12, 20 and 28‰) and dietary Chinese herbal medicine (CHM: 0, 1, 2 and 4%) on survival and growth of juvenile F. chinensis with the average initial wet body weight of 0.027±0.005 g. The experiment lasted for 5 weeks. [Result] The survival rate, specific growth rate, food consumption and apparent digestibility coefficient was increased with CHM level increasing; when attained the critical value, the survival rate, specific growth rate, food consumption and apparent digestibility coefficient decreased with CHM level increasing. Food conversion ratio decreased with CHM level increasing, and then it increased after attained the critical value. At each CHM level, the survival rate, specific growth rate, food consumption and apparent digestibility coefficient were highest at salinity of 20‰, while food conversion ratio was lowest at salinity 20‰. [Conclusion] Salinity and CHM had a significant effect on growth of F. chinensis, which should be paid more attention in the breeding.
