Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture facilities, and in particular provides a special pond for breeding medium and large octopuses and a use method thereof. Background Art

[0002] Octopuses have the characteristics of short life cycle and fast growth rate. They are one of the most promising protein resources in the ocean. At present, the medium and large octopuses that have been artificially bred in my country are mainly Octopus sinensis. During the breeding stage of octopus parents, nests of appropriate size and quantity need to be placed artificially. Octopuses have the habit of building and moving nests by themselves. Often, several nests are gathered together by an octopus to form a composite nest, resulting in low utilization rate of artificially arranged nests, and multiple nests together are not conducive to water flow exchange. At the same time, the nests currently used in production, whether pottery pots, polymer tiles or PVC pipes, are all bottom-sinking. Octopuses often eat a lot to develop gonads before spawning, and the remains or shells of fish, shrimp, crabs and shellfish need to be cleaned regularly. Bottom-sinking nests are very unfavorable for this task. In addition, feces and leftover bait will accumulate at the bottom of the sinking nest, which will easily deteriorate the water quality and breed bacteria. If you want to clean it, it will inevitably cause the nest to move, affecting the spawning process of the parents, and they may even abandon the nest and flee. Summary of the invention

[0003] The purpose of the patent of this invention is to provide a special pond for breeding medium and large octopuses and a method of using the same, so as to solve the defects of the existing medium and large octopuses such as inconvenient operation and abandonment of the nest and escape during the breeding process.

[0004] The present invention is implemented by the following technical solutions:

[0005] A special pond for breeding medium and large octopuses, comprising a breeding pond body and a nest fixed on the wall of the breeding pond, wherein the nest consists of a semi-embedded frame and an inserted nest, the inserted nest can be freely inserted into or pulled out of the frame, a feeding port is provided on the upper wall of the inserted nest, and a sewage outlet is provided on the lower wall, and the nest on the wall of the breeding pond body is arranged below the breeding water level of the breeding pond body.

[0006] Furthermore, the breeding pond body is a round, square or any other shaped breeding pond.

[0007] Furthermore, the semi-embedded frame is cylindrical or triangular prism-shaped or any other three-dimensional shape, and about 1 / 3 of the total length of the semi-embedded frame is embedded in the wall of the breeding pond body and fixedly sealed.

[0008] Furthermore, the semi-embedded frame is composed of frame bars and frame rings which are fixed as a whole. The semi-embedded frame will not deform or move. The frame bars and the frame are formed of galvanized steel rods or PVC pipes or any other hard materials.

[0009] Furthermore, the inner nest of the semi-embedded frame is made of PVC or PC or any other material.

[0010] Furthermore, the feeding port is located on the front upper wall, and the size of the feeding port is based on the individual baits such as fish, shrimp, crab, and shellfish to be put in.

[0011] Furthermore, the sewage outlet is located below the middle front section of the inner nest, and the size of the sewage outlet is based on leaking residual bait and feces.

[0012] Furthermore, the sealing cover provided at the end of the inner nest is detachable, so that the inner nest can be easily cleaned and reused.

[0013] Furthermore, circular holes or gaps are left on the left and right sides and the bottom of the inner nest. The size and number of the circular holes or gaps are appropriately increased or decreased according to the different types of octopuses to be cultured for water circulation.

[0014] The present invention also provides a method for using the special pool. After medium and large octopus parents are placed in the special pool, the water level in the special pool exceeds the uppermost nest, that is, all the nests are located below the water level. The octopus parents will enter the nest according to their breeding habits. During the breeding period, food is fed through the feeding port. The octopuses have the habit of cleaning the nests and push the remaining food and feces outward. When the remaining food and feces reach the sewage outlet, they fall into the breeding pool body. After the medium and large octopus parents have completely laid eggs, the inserted nest is pulled out and placed in a hatching pool that also has a nest for further hatching.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: during the breeding period of medium and large octopuses, the operation and management of the present invention is simple and convenient, the space of the dedicated pool is reasonably utilized, the production cost is greatly reduced, and the survival rate, mating rate, egg-laying rate and hatching rate of the parents are significantly improved.

[0020] The technical solution of the present invention is further explained below by way of embodiments, but the protection scope of the present invention is not limited in any form by the embodiments.

[0021] Example 1

[0022] like Figure 1-3 As shown, a special pond for breeding medium and large octopuses, the special pond includes a breeding pond body 1 and a nest 2 fixed on the wall of the breeding pond, the nest is composed of a frame and an inserted nest 2, the inserted nest 2 can be freely inserted into or pulled out of the frame, the front end upper wall of the inserted nest 2 is provided with a feeding port 4, the middle lower wall is provided with a sewage outlet 3, and the nest on the wall of the breeding pond body 1 is set below the breeding water level of the breeding pond body 1.

[0023] As a specific implementation, the broodstock-specific pool is a round, square or any other shaped breeding pool.

[0024] As a specific implementation, the semi-embedded frame 6 provided in the parent-only pool is cylindrical or triangular prism or any other three-dimensional shape, and about 1 / 3 of the total length of the frame is embedded in the pool wall and fixed and sealed. Since medium and large octopuses have the habit of moving their nests during the breeding process, after being fixed, they will not shift. The semi-embedded frame 6 is composed of frame bars and frame rings and fixed as a whole. The semi-embedded frame 6 will not deform or shift. The frame bars and the frame are formed of galvanized steel rods or PVC pipes or any other hard materials. The specifications of the nest are set according to the size of the medium and large octopuses, and only one medium and large octopus parent is allowed in one nest.

[0025] The material of the inner nest 2 of the semi-embedded frame 6 is PVC or PC or any other material. As a more preferred embodiment, the front end of the inner nest 2 is provided with a fixing hole for tying the inner nest 2 and the frame together with a rope or the like.

[0026] As a preferred embodiment, a feeding port 4 is provided above the front end of the inner nest 2, and the size of the feeding port 4 is based on the size of the bait such as fish, shrimp, crab, and shellfish. A sewage outlet 3 is provided below the middle front section of the inner nest 2, and the size of the sewage outlet 3 is based on the size of the residual bait and feces. The shapes of the feeding port 4 and the sewage outlet 3 are circular, and can also be square or other shapes. The positions of the feeding port and the sewage outlet are staggered front and back to prevent the bait from leaking out of the sewage outlet.

[0027] The sealing cover provided at the end of the inner nest 2 is detachable, so that the inner nest 2 can be cleaned and reused conveniently.

[0028] Circular holes or gaps 5 are left on both sides and the bottom of the inner nest 2. The size and number of the circular holes or gaps 5 are appropriately increased or decreased according to the different types of octopuses to be cultured, and are used for water circulation.

[0029] Example 2

[0030] The method for using the special pool described in Example 1 is that after the Octopus chinensis parent is placed in the special pool, the water level in the special pool exceeds the uppermost nest, that is, all the nests are located below the water level. The Octopus chinensis parent will enter the nest according to its breeding habits. During the breeding period, the Octopus chinensis has the habit of cleaning the nest and pushes the remaining bait and feces outward. When the remaining bait and feces reach the sewage outlet, they fall into the breeding pond body. After the Octopus chinensis parent has completely laid eggs, the inserted nest is pulled out and placed in a hatching pond that also has a semi-embedded frame for further hatching.
