为探究海珍品健康循环养殖技术，在实验室设计了“海参苗-海绵-大型海藻”循环养殖系统，对比考察了对照组和循环养殖系统中仿刺参苗生长、海水水质、海水及污染物的排放量。在30 d试验期间，循环养殖系统海参苗桶中海水的氨氮、亚硝酸盐、硝酸盐、活性磷酸盐和总有机碳的含量与对照组非常相近。在投加饵料相同条件下，海参苗质量由试验初始时50．0g增至试验结束时75．5g（对照组）和84．6 g （循环养殖系统）。同时，对照组与循环养殖系统分别排放了2．23 m3和0．60 m3废水；循环养殖系统排放的氨氮、亚硝酸盐、硝酸盐、活性磷酸盐和总有机碳的含量分别为对照组的21％、25％、24％、23％和59％。试验结果显示，海参苗-海绵-大型海藻循环养殖系统为海珍品的保苗和工厂化养殖提供了环境友好型技术。

This article aims to research a recirculating aquaculture system (RAS) in mariculture .Here we designed and made a RAS with ‘juvenile sea cucumber-sponge-macroalgae’ in a lab to investigate grow th of sea cucumber ,seawater quality ,discharge amount of waste seawater and pollutants in RAS and in control group .During the 30 d experiment ,concentrations of NH3-N ,NO2--N ,NO3--N ,PO3 -4 -P ,and TOC in seawater of sea cucumber tank in RAS were almost similar to those in control group .Moreovel ,fresh body weight of sea cucumber at the end of the experiment reached 75 .5 g (control group) and 84 .6 g (RAS) from body weight of 50 .0 g at the beginning of the experiment .The seawater of 2 .23 m3 (control group) and 0 .6 m3 (RAS) was respectively discharged into coastal ecosystem ;correspondingly ,pollutants also was discharged ,but discharge amount of NH3-N ,NO2--N ,NO3--N ,PO3 -4 -P ,and TOC in RCS was 21% , 25% ,24% ,23% and 59% of those in group control .T he findings indicate that RAS is an environmentally friendly technology system for industrialized mariculture .
