Description

Technical Field

[0001] The invention relates to the technical field of hatching devices, and in particular to a hatching device for improving the hatching survival rate of fry. Background Art

[0002] Fish are common animals in daily life. At present, when raising fish fry, the fertilized eggs are usually hatched into white fry in the workshop hatching pool, and then the fish fry are manually moved to the breeding pond for raising. Therefore, the operation is more troublesome and the labor cost is high. After hatching in the indoor workshop, when the fish fry are placed in the outdoor breeding pond, the fish fry cannot adapt well to the water temperature and water body in the external environment, which will cause the fish fry to have a stress response, thereby affecting the survival rate of the fish fry.

[0003] To this end, those skilled in the art have conducted research and improvements, such as an outdoor hatching rack for fry with application number CN202410259550.9. This technical solution is simple to operate, can replace the water in the transparent hatching box, and provide sufficient oxygen and automatically feed, so as to better adapt to the water temperature and water body in the external environment. However, this technical solution still has shortcomings. The hatching environment in this technical solution is single, which is not conducive to the mixed breeding of different fish, and it is difficult to purify the hatching water quality.
