Although the cultivation of fry to fingerlings takes a short time, its survival rate and physical condition have a great impact on the cultivation effect of the whole fingerlings, so it must be taken seriously.

[0003] In the prior art, Chinese Patent Publication No. CN210683397U discloses a water filtering device for small grass carp fry cultivation ponds. The filtering device includes a filtering barrel, an installation frame is provided at the bottom of the filtering barrel, a slide rail is provided between the front and rear side walls of the inner cavity of the filtering barrel, a first filter screen, a second filter screen and a third filter screen are sequentially arranged from right to left between the three chutes, one end of a feed pipe is provided above the to-be-filtered barrel, one end of a discharge pipe is provided at the lower part of the left side wall of the filtering barrel, the other end of the discharge pipe is arranged at the lower part of the cultivation pond water, and an electric discharge valve is provided on the discharge pipe. This device improves the filtering effect through multi-layer grading filtration, can discharge and clean the impurities in the to-be-filtered water storage cavity, the first filtration cavity and the second filtration cavity, can reduce the cleaning and maintenance frequency of the first filter screen, the second filter screen and the third filter screen, and at the same time can take out the first filter screen, the second filter screen and the third filter screen from the slideway respectively for maintenance and cleaning.

[0004] However, when in actual use, after the water is filtered, when the clear water enters the cultivation pond, it is not convenient to increase the oxygen in the water. The oxygen content is important for fry cultivation, so it is necessary to rely on external oxygenation equipment for oxygenation, which is rather inconvenient. When the filtering structure needs to be replaced, it is necessary to take out each layer of filter screen in turn for replacement, and the operation process is rather cumbersome, so it needs to be improved.

Oxygen can be increased while filtering, which is more conducive to the survival and cultivation of fry, and has strong functionality. When the filter element needs to be replaced, it only needs to be pulled out upward for replacement, and the replacement method is simple.
