研究了河口区采用人工调配海水培育南美白对虾亲虾和育苗池的水质状况。亲虾池水以紫外杀菌器、生物滤器循环处理,不用药,良好地控制了水质,各项指标均值为pH:8.18±0.06;NH3-Nt:1.55±0.57mg/L;NO-2-N:1.09±0.98mg/L;CODMn:20.15±2.88mg/L。亲虾成活率:95%,每尾虾产卵5万粒。以调配海水、封闭式方法培育幼体,添加适量藻液可有效调控水质,各项指标均值为pH:8.33±0.04;NH3-Nt:1.38±0.27mg/L;NO-2-N:0.15±0.16mg/L,CODMn:20.44±2.39mg/L,出苗率:70%,(8万尾/m3)。
The water quality of broodstock and nursery ponds of Penaeus vannamei was studied by using artificial seawater. The water quality of broodstock ponds was treated by UV sterilizers and biological filters, and the water quality was well controlled without medication. The mean value of each index was 8.18 ± 0.06; NH3-Nt: 1.55 ± 0.57mg / L; NO-2-N: 1.09 ± 0.98 mg / L; CODMn: 20.15 ± 2.88 mg / L. Progeny survival rate: 95%, each shrimp shrimp 50,000. The average value of each index was 8.33 ± 0.04; NH3-Nt: 1.38 ± 0.27mg / L; NO-2-N: 0.15 ± 0.16 mg / L, CODMn: 20.44 ± 2.39mg / L, germination rate: 70%, (80,000 / m3).
