报道了不同条件下闭路养鲍水中细菌数量、形态随时间的变化以及臭氧、石莼抑菌效果。实验证实 ,养鲍水中细菌数量在 ( 1.12～ 4 3.93)× 10 5ml- 1范围内变化 ,比对照海水中细菌数量高 1～ 2个数量级 ,投饵养鲍水中细菌数量比未投饵养鲍水中细菌数量略高 ,与NH4 -N、NO2 -N、COD、PO4 -P没有关联度。随着闭路养鲍时间的延长 ,养鲍水中细菌数量在水平方向上呈现较大幅度的波动 ,细菌形态呈现有规律的交替。每间隔 12h按 0 .4 17mg/ (h·L)臭氧剂量注入养鲍水中 1h能很好地抑制养鲍水中的细菌 ,但石莼抑菌效果不好。
Reported under different conditions, closed-circuit raise Bao bacteria in water volume, morphological changes with time, as well as ozone, stone antimicrobial effect. The experiment confirmed that the bacteria in the reared water changed in the range of (1.12 ~ 4. 3.93) × 10 5ml-1, which was 1 ~ 2 orders of magnitude higher than that in the control seawater. The amount of bacteria in bait- The number of bacteria in water was slightly higher than that of NH4-N, NO2-N, COD and PO4-P. With the prolongation of closed-circuit raising abalone, the amount of bacteria in rearing abalone fluctuated greatly in the horizontal direction, and the morphology of bacteria showed a regular alternation. Each interval of 12h at 0 .4 17mg / (h · L) ozone dose raised to 1h Bao Yang water can inhibit the bacteria in raise Bao water, but the effect of rock antimicrobial effect is not good.
