摘要
[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.
[目的]为中国明对虾大规模养殖和中草药制剂的推广提供理论基础。[方法]研究了盐度(12、20和28)和中草药制剂(0%、1%、2%和4%)对中国明对虾(平均初湿重0.027±0.005g)存活和生长的影响,实验周期5周,结果表明:在三个盐度水平,随饲料中中草药制剂添加量的升高,对虾存活率、特定生长率、摄食量和吸收效率均呈上升趋势,当到达临界值后,对虾存活率、特定生长率、摄食量和吸收效率随着中草药添加量的升高而下降;而饲料系数呈下降趋势,到达临界值后,然后上升。在四个中草药制剂添加水平,对虾存活率、特定生长率、摄食量和吸收效率均以20盐度处理组较高,而饲料系数以20盐度处理组较低。[结论]盐度和中草药制剂对中国明对虾生长均影响显著,因此在养殖时应加以注意。
