AI Technical Summary
The traditional sticky fish egg hatching device has aeration that causes the brown sheet to sway and damage to the fish eggs; irregular movement of the water body after the fry comes out of the shell causes the fry to be unable to stick to the bottom evenly and easily die of hypoxia; manual down-interface operation leads to mechanical damage to the fry and has a low survival rate.
A viscous fish egg hatching device was designed, which was sunk in the water body using an inner frame structure, and the brown sheet was suspended on the inner frame. The aeration pipe was set on the outside of the inner frame, and the water flowed evenly. After the fry was released from the shell, it was filtered out through the yarn mesh to avoid manual down-interface.
The balance of water flow is achieved, the damage to fish eggs caused by brown sheet collision is avoided, the survival rate of fry is improved, and the fry collection process is simplified.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, and more specifically refers to a sticky fish egg hatching device. Background Art
[0002] Traditional sticky fish egg hatching devices usually include a water container (such as a breeding pond), a palm sheet with fish eggs attached, an aeration pipe, etc. The palm sheet is hung in the water of the breeding pond by a long pole, and the aeration pipe is arranged at the bottom of the breeding pond. The hatching process is as follows: 1. Hang the palm sheet with fish eggs attached in the breeding pond, and the palm sheet is completely immersed in the water; 2. Aerate the water body; 3. After a few days, the fry hatch, remove the palm sheet, and then use a fishing net to catch the hatched water fry.
[0003] This traditional method of hatching fish eggs has the following disadvantages: 1. Since the aeration pipes are arranged at the bottom of the breeding pond, the long-term aeration will cause water convection, resulting in the palm flakes swaying and easy collision between the palm flakes, which will cause damage to the fish eggs; 2. After the fry hatch, the aeration causes the water body to continue to move irregularly, making it impossible for the hatched fry to evenly stick to the bottom, or causing the hatched fry to easily die due to lack of oxygen; 3. In order to reduce the impact of the fish net on the palm flakes during hatching, the fry are usually caught manually after the fry hatch. This method of artificially setting the net can easily cause mechanical damage to some fry, resulting in a low survival rate of the fry.
[0004] For this purpose, we provide a novel adhesive fish egg hatching device. Utility Model Content
[0005] The utility model provides a sticky fish egg hatching device to solve the problems of the existing fish egg hatching device, such as aeration easily causing the palm flakes to swing and cause damage to the fish eggs, the fry cannot be evenly attached to the bottom after hatching or they gather together and die due to lack of oxygen, and the artificial netting causes mechanical damage to the fry, resulting in a low survival rate of the fry, etc.
[0006] The utility model adopts the following technical solutions:
[0007] A sticky fish egg hatching device comprises a water container, an aeration pipe and a plurality of palm leaves with fish eggs. The hatching device also comprises an inner frame, the inner frame is supported on the inner bottom of the water container by legs, and the whole inner frame is submerged in the water body of the water container, the top and bottom of the inner frame are both hollow structures, and a gauze is fixedly provided on the inner lower part of the inner frame; the palm leaves are hung on the upper part of the inner frame by a hanging assembly, the aeration pipe is arranged between the outer side of the inner frame and the inner side of the water container, and is higher than the top surface of the legs.
[0008] In a preferred embodiment, the aeration pipe is fixedly installed around the outer side wall of the inner frame.
[0009] In a preferred embodiment, the aeration pipe is fixedly installed around the inner wall of the water container.
[0010] Preferably, the inner frame is made of PP board.
[0011] In a preferred embodiment, the water container and the inner frame are both cylindrical in shape, and the central axis of the inner frame is on the same straight line as the central axis of the water container.
[0012] In a preferred embodiment, the hanging assembly includes a support rod and a hanging rope, wherein the support rod is supported on the top surface of the water container, a plurality of hanging ropes are arranged on the support rod at intervals, and the bottom of each hanging rope is fixedly connected to one of the palm sheets.
[0013] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:
[0014] The sticky fish egg hatching device of this structure adds an inner frame with a hollow structure on the bottom and the bottom surface in the water container, the palm sheet with fish eggs is hung inside the inner frame, and the aeration pipe is arranged on the outside of the inner frame. Aeration is performed from the outside of the inner frame, and the rising bubbles carry the water flow from the outside of the top surface of the inner frame into the palm sheet placement area of the inner frame. The water body flows evenly and will not cause collision to the fish eggs on the palm sheet. As the water flows through the gauze at the bottom of the inner frame and flows out to the outside of the inner frame, the water body circulates infinitely according to the aeration amount; the hatched water fry falls on the gauze of the inner frame, which has good permeability and high dissolved oxygen, is not easy to gather and has a high survival rate; and the fry are easy to collect. After taking out the palm sheet, the inner frame is directly lifted, and the water in the inner frame is filtered out through the gauze, and the remaining fry can be directly taken out without manual netting, thereby improving the survival rate of the fry.
