| 摘 要： | 建立了一种虾、鱼、贝、藻多池循环水生态养殖及水质生物调控系统 ,该系统包括对虾养殖、鱼类养殖、贝类养殖、大型海藻栽培等 4个功能不同的养殖区 ,1个水处理区及 1个应急排水渠。通过在封闭循环系统内不同池塘中放养生态位互补的经济动植物 ,对虾池水质环境进行生物调控。结果表明 ,循环系统内虾池水层悬浮物数量、COD值、氨态氮含量比对照组单养对虾池明显降低 (t检验 ,P <0 .0 1)。养殖后排放水不处于富营养化状态 (E <1)。投入每千克对虾饲料生产0 .6 6 7kg对虾 ,同时生产 0 .0 37kg罗非鱼、0 .738kg牡蛎、0 .4 37kg江蓠 ,饲料利用率和经济效益显著增加。该养殖模式还具有防病性、环保性、高效性等优点

| Abstract: | A polyculture of shrimp-fish-shellfish-algae in water recirculating system with group ponds ecologically optimum culture pattern was designed in this paper. The system comprises four functionally different culture areas: prawn culturing area, fish culturingarea area, shellfish culturing area and large-scale marine algae cultivating area, additionally, one water treatment area, and one emergency drainage canal. Bio-manipulation of water quality was achieved by stocking different culture organisms in different ponds within the closed circulatory system. Results indicated that contents of suspensions, COD value and amounts of ammoniated nitrogen were significantly lower than those in monoculture control ponds (t test, P<0.01). The wastewater was no longer eutrophicated (E<1). Besides obtaining 0.667 kg prawns, 0.037 kg tilapia, 0.738 kg oyster, 0.437 kg Gracilaria were also produced by input of prown feed of per kilogram, tenuistipitata and feed conversion ratio and economic benefits increase notably. It has advantages, such as the noture of preventing disease, environmental protection, efficiency, etc. |
