The lawn and lake of a park in Shandong are covered with flying flocs. What effect will it have on fish?

On April 7th this year, surprisingly, in a park in Zhangdian District, Zibo City, Shandong Province, not only the lawn was covered with catkins, but also the lake without any sundries was covered with catkins in a large area, and the lake was covered with white catkins. Early in the morning, the cleaners here kept fishing for catkins on the lake. It is said that he has to work 8 hours a day and fish catkins, and he can catch hundreds of pounds. If catkins are not fished, the lake will be covered with catkins and the fish in the lake will be deprived of oxygen.

The cause of catkin and its influence on fish catkin are simply the seeds of willow with white fluff on them. When the wind is together, it will float with all kinds of winds, then fall to various places, and then fly away with the wind like catkins, so it is called catkins.

If the originally empty lake was covered with catkins blown by the wind and attached to the lake like stars, which did not attract the attention of staff and tourists, then for a long time, the fish who were originally free in the lake would not get enough air and then slowly lose their lives.

However, if the water in this lake is stagnant, or the water here is weak and slow, and has not been treated for a long time, the excessive accumulation of catkins will make this water body produce some organic matter and cause some algae, which will not only affect the water quality here, but also affect the breathing of various fish, thus affecting the survival of fish. So if some willows are planted by the lake, the staff there should pay attention to the situation caused by catkins and prepare tools to salvage catkins at any time.

Is there any way to prevent catkins from causing too much influence on fish? If fish live and live in running water, lakes are interlinked or connected. In this living water environment, even though many catkins will be broken into pieces and float with the water, the water itself has the ability of purification and self-purification, so the impact on water quality and fish will not be great. If some fish eat catkins, even if they eat catkins, it will not have a great impact on the growth of fish. So don't worry too much. However, if the water is stagnant, the water flow speed is too slow, and the self-purification ability of water is not good enough, too much catkin accumulation will affect the water quality and fish breathing. So it is necessary to salvage catkins in time. If the lake area is relatively large or there are no good tools to salvage, then the number of people salvaging catkins should be appropriately increased.
