Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a device for cleaning floating foam on the surface of a nursery pond. Background Art

[0002] The nursery pond is a pool for cultivating young aquatic animals. The survival rate of nursery is directly related to the economic benefits of aquaculture. Among them, water is the living environment of young animals, and the quality of water directly affects the health and development of young animals. In the actual breeding process, a layer of foam often forms on the water surface. Some of the foam is white, floral, and non-viscous. This type of foam is produced by the aerator. After the aerator is stopped, it is easy to disperse. When there is poor water quality foam or too much foam in the breeding water, the main reasons are the aging of algae in the breeding water, more dissolved organic matter, etc. However, in the hot summer weather, due to the high temperature and High light intensity will cause algae to multiply rapidly and cause algae overturn, so that yellow-brown or green foam will appear on the water surface; when the amount of feed is large and there are too many leftover baits and feces in the aquaculture water, it will also lead to excessive dissolved organic matter in the water, causing white or yellow-brown non-dispersible foam to appear on the water surface; at the same time, when there are more fatty acid nutrients in the bait, some oil will adhere to the surface of the bait, and then, after feeding, a layer of oil will float on the surface of the pool; when there is too much foam and oil in the pool, it will lead to a lack of dissolved oxygen in the seedling pool, and ultimately lead to a serious reduction in the survival rate of the seedlings; therefore, it is necessary to design a foam cleaning device on the surface of the seedling pool.
