Description

Technical Field

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

[0002] In the early life history stage of fish, the tissues and organs of newly hatched fry are not yet fully developed, and their ability to move and feed is weak. Fry have high requirements for water quality and dissolved oxygen. In fish breeding and production, the survival rate of fry in this stage is low. Therefore, improving the survival rate of fry in the early life history stage is the key stage for the successful fry breeding.

[0003] At present, the fry breeding methods are mainly divided into outdoor breeding ponds and circulating water system fry breeding tanks. Outdoor breeding ponds have disadvantages such as large breeding water bodies, unstable environmental water quality, and more predatory organisms. They belong to a more extensive management method. Circulating water system breeding tanks have the advantages of controllable breeding environment and stable water quality. However, there are problems such as unreasonable breeding tank design and inconvenience for management personnel to manage carefully, which affects the survival rate of fry.

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

[0005] The technical problem solved by the utility model is to provide a fry breeding device which can optimize the water quality conditions in the fry breeding process, facilitate the fine management of technical personnel, and thus improve the survival rate of fry breeding in the early life history stage.

[0006] In order to solve the above technical problems, the fry cultivation device provided by the utility model comprises: a plurality of adjustable brackets, on which the same cultivation chamber is fixedly installed, a sewage collecting chamber is provided at the bottom of the cultivation chamber, a sewage discharge pipe is connected to the bottom of the sewage collecting chamber, and a sewage collecting switch and a sewage discharge pump are installed on the sewage discharge pipe.

[0007] Preferably, floats are provided on both sides of the cultivation chamber, and the floats are used to float the top of the cultivation chamber above the water surface. Air stones are fixedly installed at the four corners of the bottom of the cultivation chamber.

[0008] Preferably, it also includes an air pump, and the output end of the air pump is connected to the air stone and the float.

[0009] Preferably, a plurality of lead sinkers are installed on four sides of the bottom of the cultivation room.

[0010] Preferably, it further comprises a controller, wherein the controller is connected to an integrated probe, and the integrated probe is located in the cultivation chamber.

[0011] Preferably, the cultivation chamber is a square net made of polyethylene material.

[0012] Compared with the related art, the fry breeding device provided by the utility model has the following beneficial effects:

[0013] The utility model provides a fry breeding device with simple structure, low cost, easy operation and simple maintenance. By arranging air stones, dead corners for fry survival can be reduced and the risk of hypoxia can be reduced. At the same time, a breeding room with adjustable height is arranged and the volume of the breeding room is adjusted to ensure that the fry have enough living space for growth. By arranging a controller, it is ensured that the breeding water quality can ensure the growth of fry and reduce the large-scale death of fry caused by water quality deterioration. By separately arranging an inverted cone-shaped sewage collection chamber, the fry can be effectively isolated from residual bait and feces, which is conducive to the rapid discharge of sewage, reduces the risk of fry infection, reduces the difficulty of cleaning the breeding device, provides a good water quality environment for the fry, and thus improves the survival rate of the fry in the early life history stage.
