摘要/Abstract

摘要： 以粘土为主要成分,通过添加A、B两组分制备出能有效去除赤潮生物的粘土复合体系.设计了三因子三水平正交实验,考察了该体系对锥状斯克里普藻(Scrippsiella trochoidea)、强壮前沟藻 (Amphidinium carterae)和赤潮异弯藻(Heterosigma akashiwo)的去除率,探讨了具有较高去除赤潮生物效果的复合体系对日本对虾(Penaeus japonicus)仔虾(体长1～1.5cm)的影响.结果表明,该体系对3种赤潮生物的去除能力为:锥状斯克里普藻>强壮前沟藻>赤潮异弯藻,各因子中粘土对赤潮生物去除效果的影响最大.日本对虾仔虾急性毒性实验结果表明,96h时对照组日本对虾仔虾死亡率高达80%,加入粘土和组分A、B的I、Ⅱ及Ⅲ组死亡率均低于0%,适当浓度的组分A、B可以提高赤潮生物的去除率而对养殖生物无害,表明该复合体系具有较好的推广和应用前景.

Abstract: An effective clay-complex system was composed on the base of clay by added other two components Aand B. Different red tide species, such as Scrippsiella trochoidea, Amphidinium carterae and Heterosigma akashiwo, were coagulated by this clay-complex system,and the optimum conditions for removal red tide organisms were obtained by means of orthogonal test. The results showed that clay was the most important factors in this complex system to coagulate these three organisms. The removal efficiency on three species was in order of Scrippsiella trochoidea > Amphidinium carterae > Heterosigma akashiwo. At the same time, a preliminary study of mortality rate on Penaeus japonicus (length between 1.0 to 1.5cm) was conducted with this system,and the result of toxic test revealed that the mortality of aquiculture shrimp in control group (nothing added) reached to 80% after 96h, however,while that of other three groups which added clay and other two components Aand B, was below 40%.Thus,it implied that the addition of clay would be harmless to Penaeus japonicas. Furthermore, suitable concentration of components Aand Bwas not harmful for the aquiculture shrimp, but increased the removal efficiency of red tide organisms. The preliminary results showed that this clay-complex system would be available in the removal of red tide organisms in filed.
