摘      要：To construct an effective circular mix-culture model and investigate its culture capacity,we established one small and one large systems,with white shrimp(Litopenaeus vannamei)and razor clam(Sinonovacula constricta)cultured in separate *** culture water from the *** was pumped to the ***,and the culture water from the *** overflowed back into the *** via *** trial I,we tested four culture densities(groups 1–4),and monitored water quality,growth indices,and digestive and immune enzyme *** the results,the nitrogen and phosphorus levels generally increased then declined after 56 days,and were lower in groups 1 and *** specific growth rate of group 2 was the *** 56 days,activities of four digestive enzymes were increased in group 2,and lysozyme activity was significantly decreased in *** in groups 1–4;Alkaline phosphatase activity of *** was increased in group 3,but decreased in *** in groups 2–4;Acid phosphatase activity was significantly higher in groups 1–3(P0.05),while SOD and CAT activities were significantly elevated in group 2(P0.05).Thus,we applied group 2 density for trial *** trial II,nitrogen and phosphorus concentrations declined significantly during the latter stages,and growth indices were higher than the control(P0.05).The yields of *** and *** were significantly higher than the control(P0.05).The results revealed a good circular mix-culture system with the optimal culture capacity for ***(40 ind m^(−2))and ***(300 ind m^(−2)),which provided a reference for the future culture of them.
