Description

[0001] This invention claims priority to the patent application filed on January 9, 2025, with application number 2025100320239 and patent title "A Small Octopus Breeding Pool and its Usage Method". Technical Field

[0002] This invention belongs to the technical field of aquaculture facilities, specifically a small breeding pond for octopuses. Background Technology

[0003] Octopuses, characterized by their short lifespans and rapid growth rates, are among the most promising protein resources in the ocean. In my country, artificial breeding research has been conducted on small octopuses such as the short-necked octopus, long-necked octopus, and Kagoshima octopus. During the breeding stage, small octopuses require artificially placed nests of suitable size and number. However, octopuses have a habit of building and moving their nests, often resulting in several nests being clustered together by a single octopus to form a complex nest. This leads to low utilization rates of artificially placed nests and disadvantages such as hindering water exchange due to the clustering of multiple nests. Furthermore, current production methods using nests, whether in ceramic jars, polymer tiles, or PVC pipes, all employ a bottom-dwelling design. Before breeding, octopuses often feed heavily to develop their gonads, requiring regular cleaning of fish, shrimp, crab, and shellfish remains or shells, which bottom-dwelling nests find highly inconvenient. In addition, the bottom of sinking nests accumulates feces and uneaten food, which can easily spoil the water and breed bacteria. Cleaning them inevitably causes the nest to move, affecting the egg-laying process of the parent birds, and may even cause them to abandon the nest and escape. Summary of the Invention

[0004] The purpose of this invention is to provide a special breeding pond for small octopuses to solve the problems of inconvenient operation and abandonment of nests in existing small octopuses breeding processes.

[0005] This invention is achieved using the following technical solution:

[0006] A small breeding pond for octopuses, the pond comprising a breeding pond body, the walls of the breeding pond body having perforated nests, and an inner insert mold that fits tightly inside the perforated nests; the perforated nests are located below the breeding water level of the breeding pond body;

[0007] As a preferred technical solution, a downwardly extending drainage trough is provided near the opening end of the hole nest, and the bottom opening of the drainage trough is connected to the aquaculture pond body, and the inner mold is provided with a drainage port on the side corresponding to the drainage trough.

[0008] As a preferred technical solution, the mold inserted into the aquaculture tank body has a protruding end, and the upper wall of the protruding end is provided with a feeding hole; furthermore, the positions of the feeding hole and the sewage outlet are staggered, with the feeding hole located on the outside of the aquaculture tank body wall and the sewage outlet located on the inside of the aquaculture tank body wall.

[0009] As a preferred technical solution, the feeding hole is round or square, more preferably square, to facilitate feeding irregular baits such as oysters and shrimp and crabs. The sewage outlet is also preferably square to facilitate the leakage of residual shells of oysters, shrimp and crabs and other baits.

[0010] As a preferred technical solution, the aquaculture pond body is circular, square, or any other shape.

[0011] As a preferred technical solution, the shape of the hole nest is cylindrical, cuboid, or other three-dimensional shape.

[0012] As a preferred technical solution, the insert mold is made of PVC, PC, or any other material.

[0013] This invention also provides a method for using the special pool. The octopus parent octopus are placed in the special pool, and the water level in the special pool is above the uppermost hole nest, that is, all the hole nests are below the water level. According to their reproductive habits, the octopus parent octopus will enter the inner mold of the hole nest. During the breeding period, they are fed through the feeding hole at the protruding end. The uneaten food and feces will be discharged into the drainage trough of the hole nest through the drainage port of the inner mold. The uneaten food and feces will then be discharged into the breeding pool body through the drainage trough. After the octopus parent octopus has completely laid eggs in the inner mold, the inner mold is pulled out and placed in an incubation pool with hole nests for further incubation.

[0014] The advantages of this invention compared to the prior art are: it facilitates operation and management of small octopuses during the breeding season, makes reasonable use of dedicated pool space, and reduces production costs. Attached Figure Description

[0021] The technical solution of the present invention will be further explained below through embodiments, but the scope of protection of the present invention is not limited in any way by the embodiments.

[0022] Example 1

[0023] like Figure 1-5 As shown, a small breeding pond for octopuses is provided. The pond includes a breeding pond body 1, and the walls of the breeding pond body 1 are provided with perforated nests 2. An inner mold is provided inside the perforated nests 2, which fits tightly with the perforated nests 2. The perforated nests 2 are located below the breeding water level of the breeding pond body 1, 20cm from the bottom.

[0024] To facilitate the cleaning of feces and uneaten feed inside the hole nest 2, a downward-extending drainage trough 3 is provided near the opening end of the hole nest 2. The drainage trough 3 is a downward-sloping trough from the inside of the wall of the breeding pond body 1 until it opens inside the breeding pond body 1. It can be a triangular pyramid or other shapes. The inner mold has a drainage port 4 on the side corresponding to the drainage trough 3.

[0025] In a preferred embodiment, a mold with a protruding end 5 is inserted into the aquaculture tank body 1, and a feeding hole 6 is provided on the upper wall of the protruding end 5; furthermore, the feeding hole 6 and the sewage outlet 4 are staggered, with the feeding hole 6 located on the outside of the wall of the aquaculture tank body 1 and the sewage outlet 4 located on the inside of the wall of the aquaculture tank body 1.

[0026] As a specific implementation technical solution, the feeding hole 6 is round or square, more preferably square, to facilitate feeding irregular baits such as oysters and shrimp and crabs. The sewage outlet 4 is also preferably square to facilitate the leakage of residual shells of baits such as oysters and shrimp and crabs.

[0027] As a specific implementation technical solution, the aquaculture pond body 1 is a circular, square, or any other shape aquaculture pond.

[0028] Hole Nest 2 is cylindrical, cuboid, or other three-dimensional shapes.

[0029] The inner mold is made of PVC, PC, or any other material.

[0030] Example 2

[0031] The special pond used in Application Example 1 is used for the breeding of octopus parents. When the octopus parents are placed in the special pond, they will burrow into the inner mold inside the hole nest 2. Fresh shellfish such as clams and oysters are fed through the feeding hole 6 on the inner mold. After feeding, the clam shells and oyster shells are pushed outward due to the octopus parents' habit of cleaning the nest. When they reach the sewage outlet 4, they fall into the sewage trough 3. Since the sewage trough 3 is sloping, the uneaten food and feces enter the breeding pond body 1. Since the bottom of the breeding pond body 1 is flat and smooth, it is easy to clean.

[0032] After the octopus has laid all its eggs in the inner mold, the inner mold is removed and the eggs are placed in an incubation pool with a similar perforated nest for further incubation.
