Description

Technical Field

[0001] This utility model relates to the field of fish fry hatching technology, specifically to a freshwater fish fry hatching device. Background Technology

[0002] my country is a major aquaculture country, with aquaculture accounting for over 70% of the country's total aquatic product output, primarily fish farming. Artificial breeding of fish fry is a crucial foundation supporting the aquaculture industry, and fry hatching is the first important step in fisheries production. One of the most important parameters in fry hatching is the hatching rate.

[0003] Chinese Patent CN220966057U discloses a freshwater fish fry hatching device, including a water tank and a hatching mechanism. The hatching mechanism includes a hatching cylinder, a fixed plate, two connecting plates, a support plate, a rotating assembly, and two sets of water circulation assemblies. The rotating assembly includes a rotating rod, a disc, two limiting blocks, a guide, and a driving component. The two sets of water circulation assemblies are symmetrically arranged on the outside of the water tank. The two connecting plates are fixedly connected to the water tank, and both ends of the support plate are fixedly connected to the two connecting plates. The hatching cylinder is placed inside the water tank, and the fixed plate is fixedly connected to the upper end of the hatching cylinder. One end of the rotating rod is fixedly connected to the fixed plate, and the other end of the rotating rod passes through the support plate and is fixedly connected to the disc. Both limiting blocks are fixedly connected to the rotating rod. Through the above arrangement, the water flow is improved, meeting the needs of fish fry hatching.

[0004] The shortcomings of the above-mentioned existing technical solutions are that the rotation of the hatching tube by the rotating component and the two sets of water circulation components cannot completely simulate the live water. Due to the rotation of the hatching tube, the fish eggs inside the hatching tube will be affected by centrifugal force for a long time, which will affect the hatching rate of the fish eggs when used for a long time. There is still room for improvement in the reliability of the device. Utility Model Content
