The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

结果表明，在循环水流量为65 立方公尺/h，水温24.5℃，氧气流量为0， 1， 2，……，10 L/min的条件下，溶氧与氧气流量回归方程为y=0.1009χ^2+0.059 4χ+5.958 8(r=0.9927)；根据物料平衡原理，推算出氧气锥的最大氧气利用率为84.56%；在最大氧气利用率的条件下，依照尼罗罗非鱼的耗氧率计算模式，推算出工厂化养鱼系统需配置氧气锥的台数。
