不同浓度臭氧处理对水质及黄沙鳖生产性能的影响

    Effects of different concentrations of ozone on water quality and production performance of Trionyx sinensis

    • 摘要: 利用不同浓度臭氧处理黄沙鳖育苗的水体, 在水温 27(±1) ℃条件下, 检测水体的水质变化及黄沙鳖生长、 成活情况。 结果表明: 臭氧能显著降解养殖水体中氨氮、 亚硝酸盐氮含量, 且能提高水体中的溶解氧含量, 水质净化效果显著。 投放 0.1 mg/L 臭氧处理的育苗水体, 黄沙鳖的平均体重为 17.5(±0.34)g, 成活率达到 91.33%, 效果最好。利用不同浓度臭氧处理黄沙鳖育苗的水体, 在水温 27(±1) ℃条件下, 检测水体的水质变化及黄沙鳖生长、 成活情况。 结果表明: 臭氧能显著降解养殖水体中氨氮、 亚硝酸盐氮含量, 且能提高水体中的溶解氧含量, 水质净化效果显著。 投放 0.1 mg/L 臭氧处理的育苗水体, 黄沙鳖的平均体重为 17.5(±0.34)g, 成活率达到 91.33%, 效果最好。关键词: 黄沙鳖; 臭氧; 养殖水体; 生长; 成活

       

      Abstract: The aquatic water of Trionyx sinensis was treated by different concentrations of ozone, at(27 ±1) ℃, the water quality was detected, and the growth and survival rate of T. sinensis was observed. The results showed that, by different concentrations of ozone, the contents of NO 2 -N and NH 4 -N in aquaculture water significantly decreased, and the dissolved oxygen(DO)content increased. After 21 days, in aquatic water treated with 0.1 mg/L ozone, the average weight of T. sinensis was 17.5(±0.16)g, the survival rate reached 91.33%, the effect was obvious.
