Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a fry screening device for aquaculture. Background Art

[0002] Aquaculture fry refers to various freshwater fish seedlings bred through artificial breeding techniques in water bodies such as ponds, lakes or rivers. They are usually used in fishery production and aquatic ecosystem protection. In aquaculture, the fry need to be initially cultivated before they can be released into the fish pond.

[0003] In aquaculture, due to the different growth conditions of fry, there will be many small fry that are not mature, so a screening device is needed to screen the fry. During the use of the existing screening device, fry of different sizes are usually screened through a screening plate. However, there will be a small number of dead fry in the fish school. The existing technology cannot screen the dead fry during screening, which will cause the dead fry to remain in the device, which not only affects the internal environment of the screening device, but also affects the ecological environment of the subsequent screening of the fish school, which is easy to cause the death of the fry. In addition, when the screening device is used, the fry will cause the screening holes to be blocked. At present, the screening efficiency is usually ensured by directly replacing the screening plate, and the fry in the screening holes cannot be cleared and separated, resulting in the loss and waste of fry.

[0004] Therefore, it is necessary to provide a new aquaculture fry screening device to solve the above-mentioned technical problems. Utility Model Content
