Description

Technical Field

[0001] The invention belongs to the technical field of aquaculture facilities, and in particular provides a special pond for breeding small 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. my country has carried out artificial breeding research on small octopuses such as short octopuses, long octopuses and Kagoshima octopuses. During the breeding stage of small octopuses, it is necessary to artificially place nests of appropriate size and quantity. 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 gathered 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 breeding, and need to regularly clean the remains or shells of fish, shrimp, crabs and shellfish. 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 pool for breeding small octopuses and a method of using the same, so as to solve the defects of existing small octopuses such as inconvenient operation and abandoning the nest and escaping during the breeding process.

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

[0005] A special pond for breeding small octopuses, the special pond comprising a breeding pond body, a hole nest is arranged on the wall of the breeding pond body, an insert mold which is closely fitted with the hole nest is arranged in the hole nest; the hole nest is arranged below the breeding water level of the breeding pond body;

[0006] As a preferred technical solution, a downwardly extending sewage trough is provided near the opening end of the hole nest, the bottom opening of the sewage trough is connected to the breeding pond body, and the inserted mold is provided with a sewage outlet on the side corresponding to the sewage trough.

[0007] As a preferred technical solution, the insert mold is provided with a protruding end in the breeding pond body, and a feeding hole is provided on the upper wall of the protruding end; further, the feeding hole and the sewage outlet are staggered front and back, the feeding hole is located outside the breeding pond body wall, and the sewage outlet is located inside the breeding pond body wall.

[0008] As a preferred technical solution, the feeding hole is round or square, more preferably square, to facilitate feeding irregular baits such as oysters, shrimps and crabs. The sewage outlet is also preferably square to facilitate leaking out the remaining shells of baits such as oysters, shrimps and crabs.

[0009] As a preferred technical solution, the breeding pond body is a round, square or any other shaped breeding pond.

[0010] As a preferred technical solution, the hole nest is in the shape of a cylinder, a cuboid or other three-dimensional shapes.

[0011] As a preferred technical solution, the insert mold is made of PVC or PC or any other material.

[0012] The present invention also provides a method for using the special pool, wherein octopus parents are placed in the special pool, the water level in the special pool exceeds the uppermost hole nest, that is, all the hole nests are located below the water level, and the octopus parents will enter the inserted mold of the hole nest according to their breeding habits, and feed through the feeding hole at the protruding end during breeding, and the remaining bait and feces will be discharged into the drainage trough of the hole nest through the drainage port of the inserted mold, and the remaining bait and feces will be discharged into the breeding pool body through the drainage trough. After the octopus parents have completely laid eggs in the inserted mold, the inserted mold is pulled out and placed in a hatching pool that also has hole nests for further hatching.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: during the breeding period of small octopuses, operation and management are convenient, the dedicated pool space is reasonably utilized, and production costs are reduced.

[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 1-5As shown, a special pond for breeding small octopuses comprises a breeding pond body 1, a hole nest 2 is arranged on the wall of the breeding pond body 1, an insert mold which fits tightly with the hole nest 2 is arranged inside the hole nest 2; the hole nest 2 is arranged below the breeding water level of the breeding pond body 1; and is 20 cm away from the bottom.

[0023] In order to facilitate the cleaning of feces and leftover bait in the hole nest 2, a downwardly extending sewage trough 3 is provided at the near opening end of the hole nest 2. The sewage trough 3 is a downwardly inclined groove from the wall of the breeding pond body 1 until it opens in the breeding pond body 1. It can be a triangular pyramid or other shapes. The inserted mold is provided with a sewage outlet 4 on the side corresponding to the sewage trough 3.

[0024] As a preferred embodiment, a protruding end 5 is inserted into the mold in the culture pond body 1, and a feeding hole 6 is provided on the upper wall of the protruding end 5; further, the positions of the feeding hole 6 and the sewage outlet 4 are staggered front and back, the feeding hole 6 is located outside the wall of the culture pond body 1, and the sewage outlet 4 is located inside the wall of the culture pond body 1.

[0025] As a specific technical implementation scheme, the feeding hole 6 is round or square, preferably square, which is convenient for feeding irregular baits such as oysters, shrimps and crabs. The sewage outlet 4 is also preferably square to facilitate the leakage of residual shells of baits such as oysters, shrimps and crabs.

[0026] As a specific technical implementation scheme, the breeding pond body 1 is a breeding pond in a circular, square or any other shape.

[0027] The hole nest 2 is in the shape of a cylinder, a cuboid or other three-dimensional shapes.

[0028] The insert mold material is PVC or PC or any other material.

[0029] Example 2

[0030] The dedicated pool of Application Example 1 is used for breeding Octopus broodstock. The Octopus broodstock is placed in the dedicated pool. The Octopus broodstock will drill into the insert mold in the hole nest 2 and feed fresh shellfish such as clams and oysters through the feeding hole 6 on the insert mold. After feeding, the clam shells and oyster shells are pushed outward due to the habit of the Octopus broodstock to clean the nest. When they reach the sewage outlet 4, they fall into the sewage trough 3. Since the sewage trough 3 is sloped, the residual bait 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.

[0031] After the octopus has completely laid eggs in the inserted mold, the inserted mold is pulled out and placed in a hatching pool that also has a hole nest for further hatching.
