摘要
[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。
[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.carinicauda in 1% traditional Chinese herbal medicine and S6 salinity fluctuation treatment group were higher than those of other treatments,and were significantly higher than those fed 1% traditional Chinese herbal medicine and salinity fluctuation maintained at S0,S3 and S9 groups.The regression analysis indicated that at S0,S3 and S6,the optimum adding level of traditional Chinese herbal medicine exhibited decreasing trend with increasing of salinity fluctuation,which were 2.74%,1.77% and 0.51%,respectively.At four adding levels of traditional Chinese herbal medicine,the optimum salinity fluctuation of E.carinicauda exhibited showed decreasing trend with increasing of adding level,which were 5.26,4.95,3.54 and 1.97,respectively.[Conclusion] The effects of salinity,traditional Chinese herbal medicine and their interaction on survival,growth,immunity of E.carinicauda were significant,therefore,we should pay attention to the breeding.
