[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide a shellfish seedling base, which avoids the interference of wild shellfish genes, realizes the prevention and control of source pathogens in aquaculture, and improves the shellfish seedling rate.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-Figure 5As shown, this embodiment provides a shellfish seedling breeding base 100, which includes a normal temperature zone, a heat preservation zone, and a heating zone. The normal temperature zone is provided with a fish breeding pond 1, a parent shellfish breeding zone 2, a water reservoir 3, a tailwater treatment system, and a water purification and regulation zone. The outlet of the fish breeding pond 1 is connected to the inlet of the parent shellfish breeding zone 2, and the outlet of the parent shellfish breeding zone 2 is connected to the inlet of the water reservoir 3. The heat preservation zone is provided with a parent shellfish breeding room, which includes multiple first water pools 16. The water reservoir 3 is used to supply water to each first water pool 16. Each first water pool 16 is used to place a male shellfish and a female shellfish, and further provide a male shellfish and a female shellfish for mating to achieve fertilization of the female shellfish. The heating area is equipped with a shellfish seed induction room, a constant-temperature land-based fish culture tank 38, and a shellfish seedling system 41. The shellfish seed induction room includes multiple second water pools 28, each of which is used to place a fertilized female shellfish. The shellfish seedlings produced by the female shellfish are then placed in the shellfish seedling system 41. The water reservoir 3 is used to supply water to each second water pool 28 and the constant-temperature land-based fish culture tank 38. The water in the constant-temperature land-based fish culture tank 38 is transported to the shellfish seedling system 41, and the water in the shellfish seedling system 41 is returned to the constant-temperature land-based fish culture tank 38. A water loop is formed between the constant-temperature land-based fish culture tank 38 and the shellfish seedling system 41, so that there is flowing water in the shellfish seedling system 41, providing nutrition for the shellfish seedlings in the shellfish seedling system 41. The tail water in each first water pool 16, each second water pool 28 and the constant temperature fish land-based breeding tank 38 is used to be discharged into the tail water treatment system, the outlet of the tail water treatment system is connected to the inlet of the water purification and regulation zone, and the outlet of the water purification and regulation zone is connected to the inlet of the fish breeding pond 1.

[0028] Feeding is performed in fish culture pond 1 to prepare for the breeding of fry. The fish excrement, along with water, flows into the parent shellfish breeding area 2 and then into the reservoir 3. Reservoir 3 provides water to the first water tank 16, the second water tank 28, the constant-temperature land-based fish culture tank 38, and the shellfish breeding system 41, thereby providing water and nutrients to the organisms in the parent shellfish breeding area 2, the first water tank 16, the second water tank 28, the constant-temperature land-based fish culture tank 38, and the shellfish breeding system 41. The tailwater from each of the first water tanks 16, the second water tanks 28, and the constant-temperature land-based fish culture tank 38 is discharged into the tailwater treatment system. After treatment in the tailwater treatment system, the tailwater enters the water purification and conditioning area. After purification and conditioning, it re-enters the fish culture pond 1, beginning a new cycle of recycling, thereby forming an internally circulating, zero-discharge shellfish breeding base 100. The entire recycling process does not involve external water or wild shellfish.

[0029] Compared with the traditional breeding and production method in an open water environment, it can prevent parent shellfish species and shellfish seedlings from being infected by pathogens in the water discharged from external aquaculture. The required fish are cultured in the fish breeding pond 1 and the constant temperature fish land-based breeding barrel 38 in the seedling base, so that there is no need to purchase fish for seedlings from outside, avoiding the low survival rate of fish seedlings after long-distance transportation, which leads to a simultaneous decrease in the shellfish seedling rate, and the risk of external fish carrying pathogens, thereby avoiding interference with wild shellfish genes, realizing the prevention and control of source pathogens in aquaculture, and improving the shellfish seedling rate.

[0030] like Figure 1 As shown, the parent shellfish breeding area 2 includes a circular enclosure dam 11, and a plurality of strip dams 12 arranged in sequence are provided in the circular enclosure dam 11. The strip dams 12 are parallel to each other, and both ends of each strip dam 12 are connected to the circular enclosure dam 11 to form a plurality of strip water runways arranged side by side. The strip water runways are used to place parent shellfish species for breeding. Each strip dam 12 is provided with an end connecting pipe 13 for connecting two strip water runways. The two end connecting pipes 13 in any two adjacent strip dams 12 are provided on the two strip dams 12. At different ends of the annular enclosure dam 11, the inlet and outlet of the annular enclosure dam 11 are respectively arranged on the outside of the two outermost strip dams 12, the inlet of the annular enclosure dam 11 is arranged at one end of the end connecting pipe 13 on a strip dam 12 adjacent to it, and the outlet of the annular enclosure dam 11 is arranged at one end of the end connecting pipe 13 on a strip dam 12 adjacent to it, so that a circuitous flow runway is formed in the annular enclosure dam 11, the outlet of the fish breeding pond 1 is connected to the inlet of the annular enclosure dam 11, and the outlet of the annular enclosure dam 11 is connected to the inlet of the water reservoir 3.

[0031] The circuitous water flow track formed enables the nutrient-supplying water discharged from the fish breeding pond 1 to flow throughout the entire circular enclosure dam 11, and then be discharged from the outlet of the circular enclosure dam 11 to the reservoir 3, so that the parent shellfish species in each area of the circular enclosure dam 11 can absorb fresh nutrients, avoiding the problem of insufficient local nutrient supply.

[0032] The outlet of the annular enclosure dam 11 is connected to the outlet of the water reservoir 3 via a first connecting pipe 14. A first power transmission component is provided on the first connecting pipe 14, which transmits water at the outlet of the annular enclosure dam 11 to the water reservoir 3. In this embodiment, the first power transmission component is a water pump.

[0033] To ensure smooth water supply from the water reservoir 3 to the first water reservoir 16, the second water reservoir 28, and the constant-temperature land-based fish breeding tank 38, an elevated water reservoir 3 can be used. That is, water supply can be achieved by utilizing the height difference between the elevated water reservoir 3 and the first water reservoir 16, the second water reservoir 28, and the constant-temperature land-based fish breeding tank 38. It should be noted that when the elevated water reservoir 3 is not used, water supply from the water reservoir 3 to the first water reservoir 16, the second water reservoir 28, and the constant-temperature land-based fish breeding tank 38 can be achieved by pumping.

[0034] Specifically, the heat preservation area includes a first greenhouse 4, and the parent shellfish breeding room is set in the first greenhouse 4. The first greenhouse 4 in this embodiment is a double-layer film multi-span greenhouse, which adopts a natural light heat preservation design.

A first control component 21 is provided on each first connecting pipe 17, and the two first water pools 16 at one end of any two adjacent rows of first water pool groups are connected by a second connecting pipe 18, and a second control component 22 is provided on each second connecting pipe 18. Specifically, two adjacent second connecting pipes 18 are arranged at different ends of the first water pool group so that water can flow in a circuitous manner in the multiple first water pools 16. A first aeration pipe 24 is provided in each first water pool 16, and each first aeration pipe 24 is connected to the first aeration device. A beneficial algae spraying pipe 26 is provided above each first water pool 16, and each beneficial algae spraying pipe 26 is connected to the beneficial algae spraying device, thereby supplying oxygen and nutrients to each first water pool 16 in a targeted manner.

[0036] At the same time, the parent shellfish species room adopts an automated pipe network shellfish supply and feeding system to feed the parent shellfish species in each first water pool 16 with nutrition.

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

[0038] When it is necessary to fill each first water pool 16 with water, open each first control component 21 and each second control component 22, and close the first drainage control component, open the second power transmission component, and transport the water in the reservoir 3 to each first water pool 16. Then close the second power transmission component, each first control component 21 and the second control component 22, so that each first water pool 16 is independent, and put a male shellfish and a female shellfish into each first water pool 16 for a male shellfish and a female shellfish to mate, so that closed seedling cultivation is carried out in each first water pool 16.

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

[0040] This embodiment also includes a controller, and the first control component 21, the second control component 22, the first drainage control component, the first power delivery component, and the second power delivery 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 delivery component, and the second power delivery component.

The lift pump 39 is connected to a controller and is used to lift water from the constant temperature land-based fish culture 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 breeding system 41 due to the height difference. The water in the shellfish breeding system 41 can flow back to the constant temperature land-based fish culture tank 38 due to the height difference.

[0048] In order to enable fish to adapt to the temperature difference during seedling placement in advance and ensure the survival rate of fish, in this embodiment, the constant temperature land-based fish breeding barrel 38 and the shellfish seedling system 41 are arranged in the same space to heat the breeding water and recycle the water nutrients. The water source exchanged between the constant temperature land-based fish breeding barrel 38 and the shellfish seedling system 41 is taken from the reservoir 3, and the tail water generated by the constant temperature land-based fish breeding barrel 38 is used to replenish the nutrient water source of the shellfish seedlings through the lifting pump 39.
