AI Technical Summary
During the existing oxygen supply process in the nursery ponds, feces, suspended solids, and other impurities float up and down, affecting the growth environment of juvenile shrimp and leading to a decrease in survival rate.
Install a support frame and lay an isolation net in the nursery pond. The oxygen supply pipe is set on top of the support frame. The mesh of the isolation net is smaller than the volume of the juvenile shrimp, so that impurities sink to the bottom of the pond. The oxygen supply pipe provides a circular flow of oxygen to prevent impurities from affecting the growth environment of the juvenile shrimp.
The design of the isolation net and oxygen supply pipe prevents impurities from rising and provides uniform oxygen flow, thus improving the survival rate of juvenile shrimp.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aquaculture equipment technology, specifically relating to a juvenile shrimp nursery pond that improves the survival rate. Background Technology
[0002] Shrimp is a food with high protein content and low fat content. It also contains abundant taurine, which can lower serum cholesterol in humans. Shrimp is rich in trace elements such as potassium, iodine, magnesium, and phosphorus, as well as vitamin A. Due to its rich nutritional value and delicious taste, shrimp is very popular among consumers, and the profit of shrimp farming is gradually increasing. Therefore, shrimp farming technology has become a focus of attention. Shrimp larvae have harsh conditions. Bacteria, temperature, oxygen, and water quality can all affect shrimp larvae. During the larval stage, it is often necessary to regularly supply oxygen to the larval pond. However, the introduction of oxygen into the larval pond causes feces, suspended solids, and other impurities to float up and down, which has a certain impact on the growth environment of juvenile shrimp and thus reduces the survival rate of juvenile shrimp. Summary of the Invention
[0003] To overcome the problem in the prior art that supplying oxygen to the seedling pond causes feces, suspended solids, and other impurities in the pond to float up and down, which affects the growth conditions of juvenile shrimp and reduces their survival rate, this utility model provides a juvenile shrimp seedling pond that improves the survival rate. While supplying oxygen to the seedling pond, it does not allow impurities in the pond to affect the juvenile shrimp, thereby improving their survival rate.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A juvenile shrimp breeding pond for improving survival rate mainly includes a breeding pond body, a support frame, an isolation net, and an oxygen supply pipe. The bottom of the breeding pond body has a conical structure and a sewage outlet is provided at the bottom. The support frame is installed inside the breeding pond body. The bottom of the isolation net is laid on the support frame, and its edge is attached to the inner wall of the breeding pond body. The oxygen supply pipe has a ring structure and is placed on the support frame. One end of the oxygen supply pipe passes through the side wall of the breeding pond and is connected to an air pump.
[0005] Furthermore, the mesh size of the isolation net is smaller than the volume of the juvenile shrimp.
[0006] Furthermore, the oxygen supply pipe is provided with equidistantly distributed exhaust ports at the top.
[0007] The beneficial effects of this utility model are:
[0008] This invention involves installing a support frame inside the seedling pond and then laying an isolation net on the support frame. Suspended solids, shrimp feces, and other impurities in the water will pass through the net and sink to the bottom of the seedling pond. An oxygen supply pipe at the top of the support frame provides oxygen, and the gas causes the water in the seedling pond to circulate continuously. Even if impurities at the bottom of the seedling pond are flowing, they will be blocked by the isolation net and will not affect the environment above the support frame. This provides a good growth environment for the shrimp and improves their survival rate. Attached Figure Description

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0013] This utility model discloses a juvenile shrimp nursery pond for improving survival rate. The nursery pond mainly includes a main body 1, a support frame 2, an isolation net 3, and an oxygen supply pipe 4. The main body 1 has a conical bottom with a drain outlet. The support frame 2 is installed inside the main body 1. The isolation net 3 is laid on the support frame 2, with its edges fitting against the inner wall of the main body 1. The oxygen supply pipe 4 has a ring structure and is placed on the support frame 2, with one end penetrating the side wall of the nursery pond and connecting to an air pump. By setting up the support frame 2 inside the nursery pond and then laying the isolation net 3 on it, suspended solids and juvenile shrimp feces in the water will pass through the mesh and sink to the bottom of the nursery pond. The oxygen supply pipe 4 supplies oxygen at the top of the support frame 2. The gas causes the water in the nursery pond to circulate continuously, and impurities in the water, even when flowing, are blocked by the isolation net 3 and will not affect the environment above the support frame 2. This utility model provides a good growth environment for juvenile shrimp, thereby improving their survival rate.
[0014] The mesh of the isolation net 3 is smaller than the volume of the juvenile shrimp; this structural design can prevent the juvenile shrimp from passing through the mesh to below the support frame 2, where there are many impurities that may affect the growth of the juvenile shrimp.
[0015] The oxygen supply pipe 4 is provided with equidistantly distributed exhaust ports at the top; this structure is conducive to providing oxygen evenly in the nursery pond, ensuring the growth conditions of juvenile shrimp.
[0016] Work process:
[0017] In practical use, the support frame 2 is installed inside the main body 1 of the seedling pond, and then the isolation net 3 is laid on the support frame 2. During the seedling process, suspended solids, shrimp feces and other impurities in the water will pass through the mesh and sink to the bottom of the main body 1 of the seedling pond. The oxygen supply pipe 4 supplies oxygen at the top of the support frame 2. The gas makes the water in the seedling pond flow continuously. Even if the impurities in the water flow, they will be blocked by the isolation net 3 and will not rise above the isolation net 3. This utility model provides a good growth environment for the shrimp, thereby improving the survival rate of the shrimp.
[0018] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
