Description

Technical Field

[0001] This utility model relates to a fish spawning and reproduction device for fish spawning and reproduction, and more particularly to a net-type fish spawning and reproduction device. Background Technology

[0002] In aquaculture, fish spawning and breeding devices are typically used to protect fish eggs and fry from being eaten by larger fish. Because medium and large-scale aquaculture farms need to protect a large number of different types of fish eggs and fry, these devices are bulky and complex in structure, making them unsuitable for small-scale aquaculture farms and home use.

[0003] To address the aforementioned issues, the applicant has applied for a utility model patent entitled "Simple Fish Spawning and Reproduction Device," suitable for small-scale farms and home use, especially for use in home aquariums. However, this utility model still has the following drawbacks: the structure is slightly complex, which is not conducive to improving processing efficiency and reducing production costs; the main body of the product is a rigid structure that cannot be folded, making it difficult to store and unusable in certain application scenarios where it needs to be folded and placed inside a breeding box; furthermore, the limited number of holes inside the spawning and reproduction container makes it difficult for fry to escape in time. Utility Model Content

[0004] The purpose of this invention is to provide a simple, foldable net-type fish spawning and reproduction device to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A net-type fish spawning and breeding device includes a mother fish net and a juvenile fish net. Both the mother fish net and the juvenile fish net are cylindrical, open at the top and closed at the bottom, and made of woven net. The mesh size of the mother fish net is larger than that of the juvenile fish net. The horizontal diameter and vertical height of the mother fish net are smaller than those of the juvenile fish net. The mother fish net is placed inside the juvenile fish net. A circular ring is connected to the upper end of the mother fish net. The upper part of the juvenile fish net is fitted with a circular foam ring for the mother fish, which is located below the mother fish sling ring. The inner diameter of the mother fish sling foam ring is smaller than the outer diameter of the mother fish sling ring. The upper end of the juvenile fish net is connected to a circular juvenile fish sling ring. The upper part of the juvenile fish net is fitted with a circular foam ring for the juvenile fish, which is located below the juvenile fish sling ring. The inner diameter of the juvenile fish sling foam ring is smaller than the outer diameter of the juvenile fish sling ring. The outer diameter of the mother fish sling foam ring is smaller than the inner diameter of the juvenile fish sling foam ring.

[0007] Preferably, in order to prevent the female fish from escaping the female fish net, the upper part of the female fish net is provided with a foam cover, the outer diameter of which is smaller than the inner diameter of the female fish net ring and larger than the inner diameter of the female fish net foam ring.

[0008] Preferably, for ease of application, the woven mesh is a plastic mesh with its own supporting strength and can be folded.

[0009] The beneficial effects of this utility model are as follows:

[0010] This utility model uses woven netting to make nets for mother fish and fry. The mother fish net is placed inside the fry net, and the fish eggs or fry laid by the mother fish can directly enter the fry net. The structure is simple, which helps to improve processing efficiency and reduce production costs. The net can be folded and has a large number of mesh holes, which makes it easy to fold, apply and store. At the same time, it helps the fry escape from the mother fish net in time to avoid being eaten by the mother fish. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figures 1-4As shown, the net-type fish spawning and breeding device of this utility model includes a mother fish net 3 and a juvenile fish net 6. Both the mother fish net 3 and the juvenile fish net 6 are cylindrical with an open top and a closed bottom, and are made of woven net. The mesh size of the mother fish net 3 is larger than that of the juvenile fish net 6. The horizontal diameter and vertical height of the mother fish net 3 are smaller than those of the juvenile fish net 6, respectively. The mother fish net 3 is placed inside the juvenile fish net 6. A circular mother fish net ring 2 is connected to the upper end of the mother fish net 3. The upper part of the net is fitted with a circular foam ring 4 for the mother fish, which is located below the mother fish ring 2. The inner diameter of the foam ring 4 is smaller than the outer diameter of the mother fish ring 2. The upper end of the juvenile fish net 6 is connected to a circular juvenile fish ring 5. The upper part of the juvenile fish net 6 is fitted with a circular foam ring 7 for the juvenile fish, which is located below the juvenile fish ring 5. The inner diameter of the foam ring 7 is smaller than the outer diameter of the juvenile fish ring 5. The outer diameter of the mother fish foam ring 4 is smaller than the inner diameter of the juvenile fish foam ring 7.

[0017] Preferably, in order to prevent the female fish from escaping from the female fish net 3, a foam cover 1 is provided at the upper part of the female fish net 3. The outer diameter of the foam cover 1 is smaller than the inner diameter of the female fish net ring 2 and larger than the inner diameter of the female fish net foam ring 4. For ease of use, the woven net is a plastic net with its own support strength and can be folded.

[0018] like Figures 1-4 As shown, in application, the juvenile fish net 6 is placed in a breeding container such as a home aquarium, with its upper part floating on the water surface through the juvenile fish net foam ring 7. The mother fish net 3 is placed inside the juvenile fish net 6, with its upper part floating on the water surface through the juvenile fish net foam ring 7. The mother fish is placed inside the mother fish net 3. After the mother fish lays eggs or gives birth to juveniles directly, the eggs or juveniles enter the juvenile fish net 6 through the mesh of the mother fish net 3, avoiding being eaten by the mother fish, and reproduce and grow inside the juvenile fish net 6. After the mother fish has completed reproduction, the mother fish net 3 can be removed to facilitate the growth of the juveniles.

[0019] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
