| 【目的】研究零换水条件下复合益生菌对罗非鱼生长性能、肌肉品质及养殖水体环境的影响，为渔
业节能减排与生态高效健康养殖提供参考。【方法】以罗非鱼为研究对象，在零换水条件下添加复合益生菌（试
验处理）开展罗非鱼养殖试验，以正常换水的养殖模式作为对照，进行罗非鱼生长性能、肌肉品质及主要水质指
标、细菌群落结构的对比。【结果】在零换水条件下，试验处理罗非鱼成活率为 83.3%，显著高于对照；饵料系
数 2.3，显著低于对照；肌肉品质方面，试验处理粗蛋白含 22.17%，显著高于对照。在整个养殖周期，试验处理
的主要水质指标维持相对稳定，水温为 26.5~30.5℃，pH 为 7.0~8.0，而亚硝酸盐为 0.039 mg/L，显著低于对照；
两组优势菌群相似，但试验处理菌群多样性指数高于对照。【结论】在零换水条件下，养殖水体中添加复合益生
菌提高了罗非鱼的成活率，降低了饵料系数，并在一定程度上改善了肌肉品质，并对养殖水环境具有改善作用，
菌群多样性指数提高，在整个养殖生产周期内对常规养殖模式依靠频繁换水释放环境压力的替代作用良好。 |

| 【Objective】The study was conducted to explore the effects of compound probiotics on the growth
performance and muscle quality of tilapia and aquaculture water environment under zero-water exchange condition, with
a view to providing references for emission reduction as well as efficient and healthy aquaculture in fishery industry. 【Method】Taking tilapia as research object and regular water exchange aquaculture mode as control group, a full-cycle
aquaculture test of tilapia was carried out by adding compound probiotics under zero-water exchange condition (experimental
group), and a comparative analysis on growth performance, muscle quality of tilapia and main water quality, microbial
community structure was conducted.【Result】Under zero-water exchange condition, the survival rate of tilapia of the
experimental group was 83.3%, significantly higher than the control group; feed coefficient was 2.3, significantly lower than
the control group; as for the muscle quality, crude protein content of the experiment group was 22.17%, significantly higher
than the control group. Main water quality of the experimental group stayed stable through the full-cycle of aquaculture period,
the water temperature was 26.5-30.5℃ , pH was 7.0-8.0, nitrite of water sample was 0.039 mg/L, significantly lower than the
control group. The dominant bacteria was similar between experimental and control groups, however, the diversity index of the
experimental group was higher than that of the control group.【Conclusion】Under zero-water exchange condition, adding
compound probiotics in aquaculture water improved the survival rate of tilapia, reduced the feed conversion rate, and improved
the muscle quality of tilapia. Meanwhile, the experimental group had strong improving effects on the water environment of
aquaculture to some certain extent, and increased the diversity index of bacterial community. During the whole aquaculture
production cycle, the zero-water exchange aquaculture of tilapia with high-activity compound probiotics had a good substitution
effect for the conventional aquaculture model which relies on frequent water changes to release environmental pressure. |
