Abstract
Description
[0001] This patent claims priority to application number 2025100321570, filed on January 9, 2025, entitled "A Special Breeding Pond for Medium and Large Octopuses and its Usage Method". Technical Field
[0002] This invention belongs to the field of aquaculture facilities technology, specifically a breeding pond for medium and large-sized octopuses. Background Technology
[0003] Octopuses, characterized by their short lifespans and rapid growth rates, are among the most promising protein resources in the ocean. Currently, the medium to large octopuses being artificially bred in my country are mainly the Chinese octopus. During the parent breeding stage, octopuses require appropriately sized and numerous nests. 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 arranged nests and disadvantages such as hindering water exchange due to multiple nests clustered together. Furthermore, current production methods using nests, whether in ceramic jars, reinforced concrete tiles, or PVC pipes, all employ a bottom-dwelling design. Before spawning, octopuses often feed heavily to develop their gonads, requiring regular cleaning of fish, shrimp, crab, and shellfish remains. Bottom-dwelling nests are highly inconvenient for this process. 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 medium and large octopuses to solve the problems of inconvenient operation and abandonment of nests in the breeding process of existing medium and large octopuses.
[0005] This invention is achieved using the following technical solution:
[0006] A breeding pond for medium to large octopuses, comprising a breeding pond body and nests fixed to the pond wall, wherein the nests consist of a semi-embedded frame and an inner nest, the inner nest being able to be freely inserted into or removed from the frame, the upper wall of the inner nest having a feeding port and the lower wall having a drainage port, and the nests on the wall of the breeding pond body being located below the breeding water level of the breeding pond body.
[0007] Furthermore, the aquaculture pond itself can be round, square, or any other shape.
[0008] Furthermore, the semi-embedded frame is cylindrical, triangular prism, or any other three-dimensional shape, with approximately one-third of its total length embedded in the pool wall of the aquaculture pond and fixed in place.
[0009] Furthermore, the semi-embedded frame is composed of frame bars and frame rings and is fixed together as a whole. The semi-embedded frame will not deform or shift. The frame bars and frame are made of galvanized steel bars or PVC pipes or any other hard material.
[0010] Furthermore, the insert nests that come with the semi-embedded frame are made of PVC, PC, or any other material.
[0011] Furthermore, the feeding port is located on the upper front wall, and the size of the feeding port is determined by the number of fish, shrimp, crabs, shellfish, and other baits that can be placed inside.
[0012] Furthermore, the drain opening is located below the middle front section of the inner nest, and the size of the drain opening is determined by whether uneaten food and feces can be leaked out.
[0013] Furthermore, the sealing cap at the end of the inner nest is removable, making it convenient to clean and reuse the inner nest.
[0014] Furthermore, round holes or slits are left on the left and right sides and bottom of the inner nest. The size and number of round holes or slits are appropriately increased or decreased according to the different octopuses being farmed, for water circulation.
[0015] The method of using the dedicated pool is as follows: after medium to large octopus parent octopuses are placed in the dedicated pool, the water level in the dedicated pool is above the uppermost nest, that is, all nests are below the water level. The parent octopus will enter the nest according to their reproductive habits. During the breeding period, they are fed through the feeding port. The octopus have the habit of cleaning the nest, pushing out uneaten food and feces. When the uneaten food and feces reach the sewage outlet, they fall into the breeding pool. After the medium to large octopus parent octopus have laid all their eggs, they pull out the inserted nest and put it into the hatching pool, which also has nests, for further incubation.
[0016] The beneficial effects of this invention compared with the prior art are as follows: During the breeding period, the operation and management of large octopuses in this invention are simple and convenient, the space of the dedicated pool is rationally utilized, the production cost is greatly reduced, and the survival rate, mating rate, egg laying rate and hatching rate of the parent organisms are significantly improved.

[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 1-3 As shown, a breeding pond for medium to large octopuses is provided. The pond includes a breeding pond body 1 and nests 2 fixed to the pond wall. The nests consist of a frame and an inner nest 2. The inner nest 2 can be freely inserted into or removed from the frame. The upper front wall of the inner nest 2 is provided with a feeding port 4, and the lower middle wall is provided with a sewage outlet 3. The nests on the wall of the breeding pond body 1 are located below the breeding water level of the breeding pond body 1.
[0024] As a specific implementation method, the breeding pond is a circular, square, or any other shape breeding pond.
[0025] In a specific implementation, the parent octopus enclosure features a semi-embedded frame 6, which is cylindrical, triangular prism-shaped, or any other three-dimensional shape. Approximately one-third of the frame's total length is embedded in the enclosure wall and fixed in place. Since medium to large octopuses have a habit of moving their nests during breeding, this fixed frame prevents displacement. The semi-embedded frame 6 is composed of frame bars and rings, fixed together as a single unit. The frame 6 will not deform or shift. The frame bars and rings are made of galvanized steel rods, PVC pipes, or any other hard material. The size of the nest is determined according to the size of the medium to large octopuses, with each nest accommodating only one medium to large octopus parent.
[0026] The inner insert 2 of the semi-embedded frame 6 is made of PVC, PC, or any other material. In a more preferred embodiment, the front end of the inner insert 2 has a fixing hole for securing the inner insert 2 to the frame with ropes or the like.
[0027] In a preferred embodiment, the inner nest 2 has a feeding port 4 at the upper front end, the size of which is determined by the number of fish, shrimp, crabs, shellfish, or other bait items that can be placed inside. The inner nest 2 has a drainage port 3 at the lower middle front section, the size of which is determined by the leakage of uneaten bait and feces. The feeding port 4 and drainage port 3 are circular, but can also be square or other shapes. The feeding port and drainage port are staggered to prevent bait from leaking out of the drainage port.
[0028] The sealing cap at the end of the inner nest 2 is removable, making it easy to clean and reuse the inner nest 2.
[0029] The inner nest 2 has round holes or gaps 5 on both sides and bottom. The size and number of round holes or gaps 5 are adjusted according to the different octopuses being farmed, and are used for water circulation.
[0030] Example 2
[0031] The method of using the special pond described in Example 1 is as follows: After the parent Chinese octopus is placed in the special pond, the water level in the special pond is above the uppermost nest, that is, all the nests are below the water level. The parent Chinese octopus will enter the nest according to their reproductive habits. During the breeding period, they are fed through the feeding port. The Chinese octopus has the habit of cleaning the nest and pushing out the uneaten food and feces. When the uneaten food and feces reach the sewage outlet, they fall into the main body of the breeding pond. After the parent Chinese octopus has completely laid eggs, they pull out the inserted nest and put it into the hatching pond with the same semi-embedded frame for further hatching.
