| Abstract: | The trials on the aeration efficiency in eel culture between the micropore aerators and the waterwheel aerators were carried out.The results showed that there was significant difference in the aeration efficiency between the ways of aeration under unloading fish.The aeration capacity of the micropore aerator was 15.85 % higher than that of the waterwheel aerator,and the aeration efficiency of the former was 2.36 time that of the latter.Under the case of loading fish,the average dissolved oxygen（DO） concentration by the micropore aerator was significant lower than that by the waterwheel aerator,but the DO concentrations all above 5 mg/L were not significantly different in the bottom water between the aeration ways.Using micropore aerator could save 57.6 % electricity and was much safer than using waterwheel aerator.The eels grew much faster in the pools using micropore aerator than those in the pools using waterwheel aerator. |
