Effects of Salinity Fluctuation and Dietary Traditional Chinese Herbal Medicines on Survival,Growth and Immunity of Exopalaemon carinicauda
[Objective]The aim of this study was to provide a theoretical basis for the large-scale breeding of Exopalaemon carinicauda.[Method]Effects of salinity fluctuation(SO,S3.S6 and S9 represented salinity fluctuations of 0.3,6 and 9 respectivley)and dietary traditionaf Chinose herbal medicines(0.1%,2%and 4%respectively)on survival,growth and immunity of E carinicauda were studied,and its experiment lasted for 60 d.[Result]The results showed that specific growth rate,feed conversion efficiency and superoxide dismutase activity of E carinicauda in the treatment group with 1% dietary traditional Chinese herbal medicine and S6 salinity fluctuation were higher than those in other treatments,which was significantly higher than the treatment groups with SO.S3 and S9 salinity fluctuation at the same adding level of 1% dietary traditional Chinese herbal medicine.The regression analysis indicated that at SO.S3 and SO salinity fluctuation,the optimal adding level of dietary traditional Chinese herbal medicines in feeds decreased with the increase of salinity fluctuation,accounting for 2.74%,1.77% and 0.51% respectively.At four adding levels of dietary traditional Chinese herbal medicines,the optimal salinity fluctuation of E carinicauda also decreased with the increase of dietary traditional Chinese herbal medicines in feeds,accounting for 5.26,4.95.3.54 and 1.97 respectively.[Conclusion]Salinity,dietary traditional Chinese herbal medicines and their jnteractions have a significant effect on survival,growth and immunity of E.carinicauda,which calls for attentions in the breeding.
