[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this invention is to provide a shellfish breeding base that avoids interference from wild shellfish genes, achieves the control of pathogens at the source in aquaculture, and improves the shellfish breeding rate.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-5As shown, this embodiment provides a shellfish breeding base 100, including an ambient temperature zone, an insulated zone, and a heated zone. The ambient temperature zone includes a fish farming pond 1, a parent shellfish breeding area 2, a water storage tank 3, a wastewater treatment system, and a water quality purification and regulation zone. The outlet of the fish farming pond 1 is connected to the inlet of the parent shellfish breeding area 2, and the outlet of the parent shellfish breeding area 2 is connected to the inlet of the water storage tank 3. The insulated zone includes parent shellfish breeding rooms, which include multiple first pools 16. The water storage tank 3 supplies water to each first pool 16. Each first pool 16 contains one male shellfish and one female shellfish, allowing the male and female shellfish to mate and achieve fertilization of the female shellfish. The heating zone includes a shellfish spawning chamber, a constant-temperature fish terrestrial culture tank 38, and a shellfish seedling system 41. The shellfish spawning chamber comprises multiple secondary pools 28, each containing a fertilized female shellfish. The shellfish seedlings produced by the female shellfish are placed in the shellfish seedling system 41. A water storage tank 3 supplies water to the secondary pools 28 and the constant-temperature fish terrestrial culture tank 38. Water from the constant-temperature fish terrestrial culture tank 38 is transferred to the shellfish seedling system 41, and water from the shellfish seedling system 41 flows back to the constant-temperature fish terrestrial culture tank 38. A water cycle is formed between the constant-temperature fish terrestrial culture tank 38 and the shellfish seedling system 41, ensuring flowing water in the shellfish seedling system 41 and providing nutrients for the shellfish seedlings within it. The wastewater from each of the first water tank 16, each of the second water tank 28, and the constant temperature fish land-based aquaculture tank 38 is discharged into the wastewater treatment system. The outlet of the wastewater treatment system is connected to the inlet of the water quality purification and regulation zone, and the outlet of the water quality purification and regulation zone is connected to the inlet of the fish aquaculture tank 1.

[0028] Fish are fed in fish farming pond 1 to prepare for the breeding of fry. After feeding, the fish excrement and water flow into the parent shellfish farming area 2, and then into the storage pond 3. The storage pond 3 provides water to the first pond 16, the second pond 28, the constant-temperature fish land-based farming tank 38, and the shellfish fry breeding system 41, thus providing water and nutrients to the organisms in these areas. Wastewater from each of the first pond 16, the second pond 28, and the constant-temperature fish land-based farming tank 38 is discharged into the wastewater treatment system. After treatment, the wastewater enters the water purification and regulation area, where it is purified and regulated before re-entering the fish farming pond 1 to begin a new cycle. This forms a zero-discharge, internally circulated shellfish fry breeding base 100, where no external water bodies or wild shellfish are involved in the entire cycle.

[0029] Compared to traditional breeding and production methods in open aquatic environments, this method avoids the infection of parent shellfish species and fry by pathogens in external aquaculture discharge water. The required fish are raised in the fish breeding pond 1 and constant-temperature land-based fish breeding tank 38 in the seedling base. This eliminates the need to purchase fish for transplanting, avoids the low survival rate of fish after long-distance transportation and the resulting decrease in shellfish seedling rate, and avoids the risk of external fish carrying pathogens. This also avoids the interference of wild shellfish genes, achieves the control of pathogens at the source in aquaculture, and improves the shellfish seedling rate.

[0030] like Figure 1 As shown, the parent shellfish breeding area 2 includes a ring-shaped enclosure dike 11, within which multiple strip-shaped dikes 12 are arranged in sequence. Each strip-shaped dike 12 is parallel to the others, and both ends of each strip-shaped dike 12 are connected to the ring-shaped enclosure dike 11 to form multiple parallel strip-shaped watercourses. These watercourses are used to hold parent shellfish for breeding. Each strip-shaped dike 12 has an end connecting pipe 13 for connecting two strip-shaped watercourses. The two end connecting pipes 13 of any two adjacent strip-shaped dikes 12 are located at the two dikes 12. At different ends, the inlet and outlet of the annular retaining dam 11 are respectively located outside the two outermost strip dams 12. The inlet of the annular retaining dam 11 is located at one end away from the end connecting pipe 13 on the adjacent strip dam 12, and the outlet of the annular retaining dam 11 is located at one end away from the end connecting pipe 13 on the adjacent strip dam 12, so that a meandering water flow track is formed in the annular retaining dam 11. The outlet of the fish farming pond 1 is connected to the inlet of the annular retaining dam 11, and the outlet of the annular retaining dam 11 is connected to the inlet of the water storage pond 3.

[0031] The meandering watercourse allows the nutrient-providing water discharged from the fish farming pond 1 to flow throughout the entire annular retaining dam 11, and then be discharged from the outlet of the annular retaining dam 11 to the reservoir 3. This ensures that the parent shellfish species in each area of ​​the annular retaining dam 11 can absorb fresh nutrients, avoiding the problem of insufficient local nutrient supply.

[0032] The outlet of the annular retaining dam 11 is connected to the outlet of the reservoir 3 via a first connecting pipe 14. A first power transmission component is installed on the first connecting pipe 14 to transport water from the outlet of the annular retaining dam 11 to the reservoir 3. In this embodiment, the first power transmission component is a water pump.

[0033] To ensure smooth water supply from reservoir 3 to the first reservoir 16, the second reservoir 28, and the constant-temperature fish land-based culture tank 38, an elevated reservoir 3 can be used. This utilizes the height difference between the elevated reservoir 3 and the first reservoir 16, the second reservoir 28, and the constant-temperature fish land-based culture tank 38 for water supply. It should be noted that if the elevated reservoir 3 is not used, water supply from reservoir 3 to the first reservoir 16, the second reservoir 28, and the constant-temperature fish land-based culture tank 38 can be achieved using a pump.

[0034] Specifically, the insulated area includes the first greenhouse 4, where the parent shellfish spawning houses are located. In this embodiment, the first greenhouse 4 is a double-layered film multi-span greenhouse, designed for natural light insulation.

[0035] like Figure 2 and Figure 3 As shown, the parent mollusks' breeding chamber includes multiple rows of first pool groups, each first pool group including multiple first pools 16 arranged sequentially. The arrangement direction of the multiple first pools 16 in each first pool group is perpendicular to the arrangement direction of the multiple rows of first pool groups. Any two adjacent first pools 16 in each first pool group are connected by a first connecting pipe 17. Each first connecting pipe 17 is buried in a first separating dam 27 used to separate two adjacent first pools 16. Each first connecting pipe 17 is provided with a first control component 21. Any two first pools 16 at one end of any two adjacent rows of first pool groups are connected by a second connecting pipe 18. Each second connecting pipe 18 is provided with a second control component 22. Specifically, two adjacent second connecting pipes 18 are located at different ends of the first pool groups so that water can flow in a meandering manner in the multiple first pools 16. Each of the first water tanks 16 is equipped with a first aeration pipe 24, which is connected to a first aeration device. Each of the first water tanks 16 is equipped with a beneficial algae spraying pipe 26 above it, which is connected to a beneficial algae spraying device, thereby supplying oxygen and nutrients to each of the first water tanks 16 in a directional manner.

[0036] Meanwhile, the parent shellfish couples' housing uses an automated pipeline-type shellfish feeding system to provide nutrition to the parent shellfish in each of the first pools 16.

[0037] Specifically, the outlet of the water storage tank 3 is connected via a second connecting pipe 15 to a first water tank 16 in the first water tank group at one end, which is farther away from the second connecting pipe 18. When the height difference of the water storage tank 3 is not used for water supply, a second power transmission component is provided on the second connecting pipe 15. In this embodiment, the second power transmission component is a water pump. The first water tank 16 in the first water tank group at the other end, which is farther away from the second connecting pipe 18, is connected to the inlet of the tailwater treatment system via a first drain pipe 19. A first drain control component is provided on the first drain pipe 19.

[0038] When it is necessary to fill each of the first pools 16 with water, the first control component 21 and the second control component 22 are turned on, the first drainage control component is turned off, and the second power transmission component is turned on to transport water from the reservoir 3 to each of the first pools 16. Then, the second power transmission component, the first control component 21 and the second control component 22 are turned off, so that each of the first pools 16 is in an independent state. One male shellfish and one female shellfish are put into each of the first pools 16 for mating, so that closed seedling cultivation can be carried out in each of the first pools 16.

[0039] When it is necessary to drain the water from each of the first water tanks 16, the first drainage control component, each of the first control components 21 and each of the second control components 22 are activated.

[0040] This embodiment also includes a controller. The first control component 21, the second control component 22, the first drainage control component, the first power transmission component, and the second power transmission component are all connected to the controller. The controller is used to control the opening and closing of the first control component 21, the second control component 22, the first drainage control component, the first power transmission component, and the second power transmission component.

[0041] In this specific embodiment, the first control component 21 is a first control valve, the second control component 22 is a second control valve, and the first drainage control component is a first drainage control valve.

[0042] Specifically, the first aeration device includes a first aeration pump and a first aeration manifold 23. The first aeration pump is connected to each first aeration pipe 24 through the first aeration manifold 23, and the first aeration pump is connected to a controller. The first aeration pipes 24 are located at the bottom of the first water tank 16.

[0043] Specifically, the beneficial algae spraying device includes a beneficial algae expansion tank 20, a beneficial algae delivery pipe 25, and a beneficial algae delivery pump. One end of the beneficial algae delivery pipe 25 is connected to the beneficial algae expansion tank 20, and the other end is connected to each beneficial algae spraying pipe 26. The beneficial algae delivery pump is installed on the beneficial algae delivery pipe 25 and is connected to the controller.

[0044] The heating zone includes a second greenhouse 5, an air heating device, geothermal pipes, a first heat pump unit, and a second heat pump unit 37. A shellfish spawning chamber, a constant-temperature fish land-based culture tank 38, and a shellfish seedling system 41 are all located within the second greenhouse 5. The air heating device heats the air within the second greenhouse 5. Geothermal pipes are buried beneath each of the second water tanks 28. The first heat pump unit provides a heat source to the geothermal pipes, thereby heating the second water tank 28 and the water inside. The second heat pump unit 37 heats the water introduced into the constant-temperature fish land-based culture tank 38. In this embodiment, the air heating device, the first heat pump unit, and the second heat pump unit 37 are all connected to a controller.

[0045] Specifically, in this embodiment, the second greenhouse 5 is a double-layered glass greenhouse, and an air heating device is used to heat the air inside the greenhouse to maintain a certain temperature. In this embodiment, the air heating device is an air conditioner.

[0046] In this embodiment, the outlet of the first heat pump unit is connected to the inlet of the geothermal pipeline, and the outlet of the geothermal pipeline is connected to the inlet of the first heat pump unit.

[0047] like Figure 5 As shown, the second greenhouse 5 is also equipped with a water collection component 36 and a high-level water storage component 40. The outlet of the water storage tank 3 is connected to the inlet of the water collection component 36 through a third connecting pipe. A third power transmission component is installed on the third connecting pipe, which in this embodiment is a water pump. The outlet of the water collection component 36 is connected to the inlet of the second heat pump unit 37 through a pipeline. The outlet of the second heat pump unit 37 is connected to the inlet of the constant-temperature fish land-based aquaculture tank 38 through a pipeline. The inlet of the constant-temperature fish land-based aquaculture tank 38 is connected to the high-level water storage component 40 through a lift pipe. A lift pump 39 is installed on the lift pipe and is connected to a controller. The lift pump 39 is used to lift the water in the constant-temperature fish land-based aquaculture tank 38 to the high-level water storage component 40. The water in the high-level water storage component 40 can flow to the shellfish seedling system 41 under the action of the height difference. The water in the shellfish seedling system 41 can flow back to the constant-temperature fish land-based aquaculture tank 38 under the action of the height difference.

[0048] To ensure the survival rate of fish by allowing them to adapt to the temperature difference during fry rearing in advance, in this embodiment, the constant temperature fish land-based culture tank 38 and the shellfish fry rearing system 41 are arranged in the same space to heat the culture water and recycle the water nutrients. The water source for the exchange between the constant temperature fish land-based culture tank 38 and the shellfish fry rearing system 41 is taken from the water storage tank 3. The tailwater generated by the constant temperature fish land-based culture tank 38 is used to replenish the nutrient water source for the shellfish fry through the lift pump 39.

[0049] The drain outlet of the constant-temperature fish land-based aquaculture tank 38 is connected to the inlet of the tailwater treatment system via a second drain pipe. A second drain control component is installed on the second drain pipe and is connected to a controller. The second drain control component is normally in the closed state. When drainage from the constant-temperature fish land-based aquaculture tank 38 is required, the controller controls the second drain control component to open. In this embodiment, the second drain control component is a second drain valve.

[0050] In this specific embodiment, multiple constant-temperature fish land-based aquaculture tanks 38, lift pumps 39, and high-level water storage components 40 can be configured.

Each fourth connecting pipe 32 is equipped with a fourth control component 33. Each second pool 28 is equipped with a second aeration pipe 35, and each second aeration pipe 35 is connected to a second aeration device. Specifically, two adjacent fourth connecting pipes 32 are located at different ends of the first pool group, so that water can flow in a meandering manner in the multiple second pools 28.

[0052] Meanwhile, the shellfish breeding room uses an automated pipeline shellfish feeding system to provide nutrition to the fertilized female shellfish in each of the second pools 28.

[0053] Specifically, the outlet of the water storage tank 3 is connected via a fourth connecting pipe to a second water tank 28 in the second water tank group at one end, which is farther away from the fourth connecting pipe 32. When the height difference of the water storage tank 3 is not used for water supply, a fourth power transmission component is provided on the fourth connecting pipe. In this embodiment, the fourth power transmission component is a water pump. The second water tank 28 in the second water tank group at the other end, which is farther away from the fourth connecting pipe 32, is connected to the inlet of the tailwater treatment system via a third drain pipe. A third drain control component is provided on the third drain pipe.

[0054] When it is necessary to fill each of the second pools 28 with water, the third control component 31 and the fourth control component 33 are turned on, the third drainage control component is turned off, and the fourth power transmission component is turned on to transport the water in the storage tank 3 to each of the second pools 28. Then, the fourth power transmission component, the third control component 31 and the fourth control component 33 are turned off, so that each of the second pools 28 is in an independent state. A fertilized female mollusk is placed in each of the second pools 28 for it to reproduce.

[0055] When drainage of each of the second water tanks 28 is required, the third drainage control component, each of the third control components 31 and each of the fourth control components 33 are activated.
