The connection of the breeding module 12 adopts a detachable connection method, which is conducive to timely adjusting the production scale of the greenhouse and facilitating the placement and removal of the breeding water tank 11.

[0024] The above setting takes a 14m*14m greenhouse as an example. The greenhouse is a factory building mainly made of steel structure. Figure 2 As shown, 7 rows of breeding modules 12 are arranged parallel to the side length of the greenhouse, 4 rows of breeding modules 12 are arranged horizontally, and 3 layers are arranged in each row. Two breeding water tanks 11 are placed on each layer of each breeding module 12. Each breeding module 12 in each row is movably connected with a breeding spacing of 120 cm, and the spacing between the two ends and the long greenhouse wall is 120 cm. The length, width and height of each breeding module 12 are 160 cm*140 cm*260 cm respectively. Each breeding module 12 is flat with 2 breeding boxes, and a total of 6 breeding water tanks 11 are placed on 3 layers.

[0025] The aquaculture water tank 11 is made of plastic injection molding. The funnel-shaped central sewage discharge hole 14 at the bottom of the aquaculture water tank 11 is a 1 cm round hole.

[0027] The main body of the filter 9 is made of sponge fiber material, with a length, width and height of 60cm*25cm*15cm. A plastic basket with a hollow bottom is placed in the sink 10, and the hollow bottom size of the plastic basket is the same as the size of the sponge fiber. The sponge fiber is loaded into the plastic basket to form the filter 9.

[0028] Freshwater fish greenhouse three-dimensional factory-scale flow-through aquaculture is a high-density aquaculture. Short-term power outage and hypoxia will cause great losses. Therefore, a backup generator set must be configured and an aerator 13 must be set for each aquaculture water tank 11.

[0029] The utility model also corresponds to a breeding method: a three-dimensional factory-based freshwater fish greenhouse flowing water breeding method, including pre-breeding preparation, seedling stocking, water replacement, feed feeding, water quality requirements, winter and summer constant temperature adjustment, daily management, harvesting and fishing and other major technical links and steps.

[0030] 1. Preparation before breeding. About 10 days before stocking, build the breeding module 12 on the foundation of the breeding module 12 in the greenhouse, place the breeding water tank 11, install the comprehensive water pool 7 and the hot water pool 8 above the breeding module 12, and then fill the cold water pool 6, the comprehensive water pool 7, the breeding water tank 11, and the hot water pool 8 with water, add povidone iodine (4.5-7.5mg / m 3 ) or quicklime (150-200g / m 3 ) for disinfection. After 7 days, when the toxicity has dissipated, soak it in clean water for 1-2 days and then change the water. After the water quality is tested and qualified, it can be used for breeding.

[0031] 2. Replace water. During the breeding process, generally in spring, summer and autumn, the reservoir 3 or natural water source is used for breeding. In winter, the hot water generated by the photovoltaic panels 2 is used to adjust the water temperature. In summer, the water in the deep well pool 5 is used to supply the cold water pool 6 for cooling. In the process of water replacement, any reservoir is selected to adjust the water injection of the comprehensive water pool 7, and the water in the comprehensive water pool 7 is used to carry out flow breeding in the breeding water tank 11. Set up a comprehensive water pool 7, use the water in any reservoir, adjust the water volume ratio according to the season, temperature changes, and production needs, flexibly adjust the water in the breeding water tank 11, and ensure that the water temperature and water quality of the water in the breeding water tank 11 are qualified. The comprehensive water pool 7 is circulated up and down by the automatic water pump in the cold water pool 6 for 3-5 days, and 30% of new water is added for replacement, and it is flexibly adjusted according to the temperature changes.

[0032] 3. Stocking of seedlings. Use seedlings produced by regular enterprises with high uniformity, strong resistance to water flow and strong physique. Soak them in 3% salt water for 5 minutes before stocking. The water in the breeding water tank 11 can be added to the container where the seedlings are located in multiple times. Adjust the water temperature to allow the seedlings to adapt to the water in the breeding water tank 11 until the water temperature in the container is basically the same as that in the breeding water tank 11. Then choose to put the seedlings into the breeding water tank 11 in the morning or evening.

[0033] 4. Feeding. Feed at regular times, with fixed quality and quantity every day, and the amount of feed should be based on the instructions for the feed.

[0034] 5. Water quality requirements. The water quality is tested every 3-5 days. In this embodiment, the water quality is tested every 3 days. The water is automatically pumped through the integrated water pool 7 and the cold water pool 6, and the aerator 13 is used to increase oxygen to maintain the pH value between 6.5 and 8.5 and the dissolved oxygen above 6 mg / L.

[0035] 6. Daily management. In daily management, in addition to frequently observing the feeding and activity of the fish in the breeding water tank 11, it is necessary to clean the feces and residual bait accumulated in the filter 9 every day, pay attention to the changes in water quality in the comprehensive pool 7, breeding water tank 11, and cold water pool 6, and record them. When the dissolved oxygen content in the water is lower than 6mg / L, the water quality deteriorates, and the feeding should be reduced or stopped in rainy or hot weather. Freshwater fish are grown fast in greenhouses, have vigorous metabolism, and consume a lot of oxygen.

[0036] 7. Harvest and fishing. Freshwater fish in greenhouse three-dimensional factory-scale water culture grow fast and can be harvested and put on the market in 5-6 months. When fishing, just turn off the valve 4, the switch between the comprehensive pool 7 and the breeding water tank 11, and the automatic water pump of the cold water pool 6 will stop circulating water. When the water in the breeding water tank 11 is exhausted, the breeding water tank 11 can be lifted off the breeding module 12 and loaded onto a professional fish truck for transportation to the market.

[0037] In this embodiment, the length, width and height of the breeding water tank 11 are 150cm*75cm*100cm. A single breeding water tank 11 can raise 140 largemouth bass, with an average weight of 500 grams. According to 70% of the average market price of 32 yuan / jin in the Chengyang Vegetable and Aquatic Products Wholesale Market in Qingdao on June 14, 2024, the output value of a single breeding greenhouse 1 is 235,200 yuan, and the comprehensive breeding cost is about 100,000 yuan. The utility model is a new breeding model that can be replicated and has strong plasticity in breeding scale. It will become an important technical means for green aquaculture and rural revitalization.

[0038] The utility model adopts the above-mentioned settings and methods, and utilizes the three-dimensional factory water-flowing aquaculture device to increase the aquaculture density per unit land area; utilizes multiple types of reservoirs to solve the problem of low or high natural water temperature caused by seasonal changes, and solves the problem of insufficient water supply caused by drought in extreme weather; the structural design of the aquaculture water tank 11 can timely clean up the sediments in the water body such as feces and residual bait, timely replace new water, effectively purify the water body, and ensure that the water quality in the aquaculture water tank 11 is qualified. Because the quality of the seedlings is controlled before the seedlings are released and the seedlings are soaked in salt water, diseases generally do not occur in the aquaculture greenhouse 1, and prevention and control are mainly used.
