盐度波动和中草药制剂对脊尾白虾存活·生长和免疫的影响

[目的]为大规模脊尾白虾的养殖提供理论基础。[方法]研究了盐度波动幅度（S0、S3、S6和S9分别代表盐度波动幅度为0、3、6和9）和中草药制剂（0、1%、2%和4%）对脊尾白虾存活、生长和免疫的影响,试验周期60 d。[结果]1%中草药和S6盐度波动处理组脊尾白虾的特定生长率、饲料转换效率和超氧化物歧化酶活性均高于其他处理,且显著高于同一中草药添加水平的S0,S3和S9盐度波动处理组。回归分析结果表明,在S0、S3和S6 3个盐度波动水平,随盐度波动幅度增加,饲料中的中草药制剂的最适添加量呈下降趋势,分别为2.74%、1.77%和0.51%;在4个中草药制剂添加水平,随饲料中的中草药制剂添加量增加,脊尾白虾生长的最适盐度波动幅度呈下降趋势,分别为5.26、4.95、3.54和1.97。[结论]盐度、中草药制剂及其相互作用对脊尾白虾的存活、生长和免疫均有显著影响,因此在养殖时应加以注意。

Effects of Salinity Fluctuation and Dietary Traditional Chinese Herbal Medicines on Survival, Growth and Immunity of Exopalaemon carinicauda

[Objective] The aim was to provide theoretical basis for large-scale culture of Exopalaemon carinicauda.[Method] The effects of salinity fluctuation(S0,S3,S6 and S9 represent salinity fluctuations of 0,3,6 and 9) and dietary traditional Chinese herbal medicines(0%,1%,2% and 4%) on survival,growth and immune factors of juvenile E.carinicauda were studied.The experiment lasted for 60 d.[Result] The results showed that specific growth rate,food conversion efficiency and superoxide dismutase activity of E.carin...
