Description

Technical Field

[0001] The present invention particularly relates to a shrimp fry cultivation system and a shrimp fry cultivation device including the shrimp fry cultivation system. Background Art

[0002] In the traditional shrimp fry cultivation process, the co-culture of female shrimps and shrimp fries in the breeding pond is a long-existing operation mode. The following technical bottlenecks exist in this mode:

[0003] (1) Serious biological loss: Female shrimps will actively prey on shrimp fries with weak swimming ability in a hungry state. Research shows that in an unsorted co-culture pond, the mortality rate of shrimp fries caused by predation by female shrimps can reach 30%-45%;

[0004] (2) Risk of physical damage: The strong water flow impact and limb collision generated during the activities of adult female shrimps are likely to cause shell damage or internal organ compression and death of shrimp fries;

[0005] (3) Growth space competition: Female shrimps preferentially occupy oxygen-rich areas and bait resources, resulting in slow development of shrimp fries and a decrease in population uniformity.

[0006] Existing solutions mainly rely on later manual sorting, but there are significant drawbacks:

[0007] (1) Operational damage: Scratching by the net and stress caused by being out of water during the sorting process will cause a mechanical damage mortality rate of 5%-8% of shrimp fries;

[0008] (2) Time lag: There is a conflict between the best sorting window period and the molting cycle of shrimp fries, and it is difficult for manual sorting to accurately grasp the timing;

[0009] (3) Cost pressure: 3-5 labor forces need to be invested per mu of breeding pond for continuous operation, and the sorting cost is high. Summary of the Invention

[0034] A shrimp fry cultivation system, referring to Figures 1-4 , includes a cultivation pond 1. A screen component for dividing the cultivation pond 1 into a female shrimp mixing area 11 and a shrimp fry cultivation area 12 is arranged in the cultivation pond 1. The screen component is provided with filter mesh holes that only allow shrimp fry 1-1 to enter the shrimp fry cultivation area 12 from the female shrimp mixing area 11. Fixed frames 3 fixedly connected to the cultivation pond 1 are arranged on both sides of the screen component. A horizontal connecting member 4 is arranged on the screen component, and a vertical connecting member 5 is arranged on the fixed frame 3. After one end of the horizontal connecting member 4 is inserted horizontally into the fixed frame 3, the lower end of the vertical connecting member 5 extends into the fixed frame 3 to form a cross-interlocking structure with the horizontal connecting member 4. An anti-disengagement member for restricting the rotational displacement of the vertical connecting member 5 is arranged on the fixed frame 3.

[0035] Furthermore, the interlocking structure of the horizontal connecting member 4 and the vertical connecting member 5 includes: a clamping groove 41 arranged on the horizontal connecting member 4. After the horizontal connecting member 4 passes through the fixed frame 3, the lower end of the vertical connecting member 5 is inserted into the clamping groove 41 to form an interference fit. A locking nut 51 is threadedly connected to the end of the horizontal connecting member 4 extending out of the fixed frame 3, and the inner end face of the locking nut 51 is in press-fit connection with the outer wall of the fixed frame 3.

[0036] Furthermore, the anti-disengagement member includes a rotating platform 61 rotatably arranged on the top of the fixed frame 3. The vertical connecting member 5 is connected to the rotating platform 61. Radial abutting grooves 62 are symmetrically arranged on the rotating platform 61. A locking member 63 corresponding to the radial abutting grooves 62 is arranged on the fixed frame 3. The rotating platform 61 drives the vertical connecting member 5 to rotate synchronously. When the locking member 63 abuts into the radial abutting grooves 62, the rotational freedom of the rotating platform 61 is restricted.

[0037] Furthermore, an installation groove 7 for installing the rotating platform 61 is arranged on the rotating platform 61.

[0038] Further, the locking member 63 is a screw.

[0039] Further, the screen assembly includes a screen 81, rigid fixing plates 82 symmetrically arranged on both side edges of the screen 81, the transverse connecting member 4 is connected to the rigid fixing plates 82, and both side edges of the screen 81 are covered and fixed within the rigid fixing plates 82.

[0040] Further, the screen assembly further includes a plurality of vertical rods 9, which are arranged at intervals along the length direction of the screen 81; the vertical rods 9 and the screen 81 are fixedly connected by detachable straps for preventing the screen 81 from sagging.

[0041] Further, a shrimp fry breeding device is provided with an ultraviolet sterilizer on the breeding pond.

[0042] The working principle of the present invention is:

[0043] As Figure 1As shown in the figure, the shrimp fry 1-1 cultivation system includes a cultivation pond 1 (there is water in the cultivation pond, and in practical applications, the cultivation pond can be a pond). A screen component is arranged in the cultivation pond 1. The screen component divides the cultivation pond 1 into a female shrimp mixing area 11 and a shrimp fry cultivation area 12. The filter holes on the screen component only allow the shrimp fry 1-1 to enter the shrimp fry cultivation area 12 from the female shrimp mixing area 11, so as to effectively separate the female shrimp 1-2 from the shrimp fry 1-1, facilitate the growth of the shrimp fry 1-1 in a relatively independent environment, and improve the survival rate (it should be noted that: some shrimp fry will swim back to the female shrimp mixing area 11, but most shrimp fry will swim through the filter holes to the shrimp fry cultivation area 12 and will not swim back to the female shrimp mixing area 11. This application mainly separates most of the shrimp fry from the female shrimp mixing area 11, provides a larger space for the growth of the shrimp fry, and at the same time reduces the amount of female shrimp 1-2 preying on shrimp fry 1-1). The shrimp fry cultivation system of this application divides the cultivation pond 1 into a female shrimp mixing area 11 and a shrimp fry cultivation area 12 through the screen component, and only allows the shrimp fry 1-1 to enter the shrimp fry cultivation area 12 from the female shrimp mixing area 11, effectively avoiding the female shrimp 1-2 preying on the shrimp fry 1-1 in a hungry state, and reducing the mortality rate of the shrimp fry 1-1 caused by the predation of the female shrimp 1-2; the screen component separates the female shrimp 1-2 from the shrimp fry 1-1. The violent water flow impact and limb collision generated by the activities of the adult female shrimp 1-2 are mainly limited to the female shrimp mixing area 11. The shrimp fry 1-1 is in a relatively independent cultivation area, and the risk of death due to shell injury or internal organ compression is greatly reduced. It provides a relatively independent and resource-relatively concentrated cultivation space for the shrimp fry 1-1. The female shrimp 1-2 no longer preferentially occupies the oxygen-rich area and bait resources, and the shrimp fry 1-1 can fully obtain the oxygen and nutrients required for growth. In addition, this system does not require later manual sorting, saving the sorting cost of 3-5 labor forces per mu of cultivation pond for continuous operation. At the same time, it improves the survival rate of the shrimp fry 1-1, reduces the overall cultivation cost, improves the cultivation efficiency, and provides strong support for large-scale cultivation.

[0044] Fixed frames 3 are arranged on both sides of the screen component. The fixed frames 3 are fixedly connected to the cultivation pond 1 to provide stable support for the screen component. A horizontal connecting member 4 is provided on the screen component, and a vertical connecting member 5 is provided on the fixed frame 3. After one end of the horizontal connecting member 4 is inserted into the fixed frame 3 in the horizontal direction, the lower end of the vertical connecting member 5 extends into the fixed frame 3 to form a cross-interlocking structure with the horizontal connecting member 4. This structural design enhances the connection stability between the screen component and the fixed frame 3, prevents the screen component from shaking or shifting during use, and ensures the smooth progress of the shrimp fry 1-1 cultivation process.

[0045] To prevent the vertical connecting member 5 from rotating and displacing, an anti-disengagement member is provided on the fixed frame 3. As Figure 3 and Figure 4As shown in the figure, the anti - detachment component includes a rotating platform 61 rotatably arranged on the top of the fixed frame 3. The vertical connecting member 5 is connected to the lower end of the rotating platform 61. Radial abutting grooves 62 are symmetrically arranged on the rotating platform 61. A locking member 63 corresponding to the radial abutting grooves 62 is arranged on the fixed frame 3. The shape and size of the radial abutting grooves 62 should match the locking member 63 to ensure the locking effect. The locking member 63, such as a screw, is installed on the fixed frame 3, and its position corresponds to the radial abutting grooves 62 on the rotating platform 61. The rotating platform 61 drives the vertical connecting member 5 to rotate synchronously. When the locking member 63 abuts into the radial abutting grooves 62, the rotational freedom of the rotating platform 61 is restricted, thereby effectively restricting the rotational displacement of the vertical connecting member 5 and further improving the stability of the structure. An installation groove 7 is arranged at the bottom of the rotating platform 61 for facilitating the installation of the rotating platform 61.

[0046] Furthermore, the interlocking structure between the horizontal connecting member 4 and the vertical connecting member 5 includes a clamping groove 41 arranged on the horizontal connecting member 4. After the horizontal connecting member 4 passes through the fixed frame 3, the lower end of the vertical connecting member 5 is inserted into the clamping groove 41 to form an interference fit. A locking nut 51 is threadedly connected to the end of the horizontal connecting member 4 extending out of the fixed frame 3. The inner end face of the locking nut 51 is in press - fit with the outer wall of the fixed frame 3. This cooperation method not only enhances the connection tightness but also facilitates installation and disassembly.

[0047] In terms of the structure of the screen assembly, as Figure 3 shown, the screen assembly includes a screen 81, rigid fixing plates 82 symmetrically arranged on both side edges of the screen 81. The horizontal connecting member 4 is connected to the rigid fixing plates 82. Both side edges of the screen 81 are wrapped and fixed inside the rigid fixing plates 82. This design makes the screen assembly have higher structural strength and stability. In addition, the screen assembly further includes multiple vertical rods 9. The vertical rods 9 are arranged at intervals along the length direction of the screen 81. The vertical rods 9 and the screen 81 are fixedly connected by detachable straps to prevent the screen 81 from sagging, ensure that the screen 81 always maintains a good working state, and extend its service life.

[0048] Through the reasonable combination and delicate design of the above - mentioned components, this shrimp fry cultivation system realizes the effective separation of female shrimp 1 - 2 and shrimp fry 1 - 1, provides a good cultivation environment for shrimp fry 1 - 1, improves the survival rate of shrimp fry 1 - 1, and at the same time ensures the stability and reliability of the whole system, which is convenient for popularization and application in actual aquaculture.

[0049] Based on the above technical solutions, the present application also provides an ultraviolet sterilizer on the culture pond of the shrimp seedling cultivation system. By precisely controlling the ultraviolet dose and operation distance, the ultraviolet sterilizer can avoid harming the shrimp seedlings, effectively kill harmful microorganisms in the water, improve water quality, and provide a healthy growth environment for the shrimp seedlings. Since the working principle of the ultraviolet sterilizer belongs to a mature technical means in the technical field, the working principle will not be elaborated herein.

[0050] As Example 2, Figure 6 It is a schematic structural diagram of the shrimp seedling cultivation system. The female shrimp mixing area is further divided into a breeding shrimp mating pond and a cultivation pond. The breeding shrimp mating pond and the cultivation pond are arranged side by side (in parallel), and their shrimp seedlings enter the shrimp seedling cultivation area through the screen assembly at the same time. If there are problems in the breeding shrimp mating pond (such as water quality deterioration, diseases), the cultivation pond can still supply shrimp seedlings independently to avoid total failure. If the feeding in the cultivation pond is insufficient, the shrimp seedlings in the breeding shrimp mating pond can supplement and enter the shrimp seedling cultivation area.
