[0019] 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.

[0020] like Figures 1 to 2As shown, the largemouth bass aquaculture system provided by this utility model mainly includes an outer wall 1, a culture pond 2, a water trough 3, and aeration equipment. Both the outer wall 1 and the water trough 3 are constructed of brick and concrete to ensure the system's stability and durability. The culture pond 2 is located inside the outer wall 1, and the water trough 3 is arranged around the outer perimeter of the culture pond 2, forming functional zones including a water-pushing area 4, a culture area 5, and a waste collection area 6.

[0021] The flow channel 3 consists of a water-pushing zone 4, an aquaculture zone 5, and a waste collection zone 6. These zones are separated by a net 7 to ensure smooth water flow and centralized treatment of pollutants. The water-pushing zone 4 is equipped with a water-pushing and oxygenation equipment 8 to improve water flow and dissolved oxygen levels. The aquaculture zone 5 is the main growth area for largemouth bass. The waste collection zone 6 is used to collect uneaten feed and feces generated during the aquaculture process.

[0022] When configuring the water trough 3, each aquaculture pond 2 should be equipped with at least one water trough 3, and each water trough 3 should be equipped with at least one water-pushing aeration device 8. In another embodiment, each aquaculture pond 2 can be equipped with two water troughs 3, and each pair of water troughs 3 should be equipped with one microporous aeration device 9 to further optimize the dissolved oxygen effect of the water. For example, one water trough 3 can be configured for every 6667㎡ of pond area in aquaculture pond 2. The specifications of the water trough 3 are 20m-25m in length, 5m-8m in width, and 2.2m-2.5m in depth. When one water trough 3 is configured, 81 sets of 2.2kW water-pushing aeration devices are installed, with an air output of more than 140m³. 3 / h; When setting up two flow channels 3, each pair of flow channels 3 should be equipped with one set of 1.5kW~3kW microporous aeration equipment 9, and the aeration supply should be greater than 30m³ / h. 3 / h.

[0023] When configuring the aeration equipment, a waterwheel-type aerator 10 is also installed at each of the four corners of the aquaculture pond 2 to ensure uniform dissolved oxygen in all areas of the pond. By working together with the water-pushing aerator 8 and the microporous aeration aerator 9, the overall aeration efficiency can be improved.

[0024] Furthermore, a purification zone 11 is set up around the water flow channel 3, with its area accounting for 50% to 80% of the area of ​​the aquaculture pond 2. The purification zone 11 is used to further treat pollutants in the water to ensure the cleanliness and stability of the aquaculture water quality. Aquatic plants such as water spinach, Elodea nuttallii, and water hyacinth can be planted in the purification zone 11.

[0025] Aquaculture Techniques: Before stocking largemouth bass fry, a trial run of the engineered recirculating aquaculture system should be conducted to check the equipment's operation and set all parameters. Select large-sized largemouth bass fry for stocking, with 20,000 to 30,000 fry per three-tank flow. Feed them daily with a specialized largemouth bass feed containing at least 45% protein, 2-3 times a day, at a daily feeding rate of 2%-5%. Maintain water transparency at 20-35cm, pH between 7.0 and 8.5, and dissolved oxygen ≥5mg / L. 1-2 hours after each feeding, promptly remove feces and uneaten feed by activating an external sludge pump.

[0026] Compared to traditional pond aquaculture, the engineered recirculating aquaculture system for largemouth bass ensures stable dissolved oxygen levels of 5-8 mg / L, increasing the bass's feeding rate and growth rate. This reduces feeding and harvesting costs, significantly improving yield per unit area. The aquaculture water undergoes collection, filtration, and purification before being recycled, achieving a water resource recycling rate of over 90%, greatly reducing water waste and resulting in significant cost reduction and efficiency improvement.

[0027] In summary, the largemouth bass aquaculture system provided by this invention optimizes the aquaculture environment, ensures clean water quality, and improves resource utilization efficiency, thereby achieving the goals of high-yield, high-quality, and environmentally friendly aquaculture. In terms of structural design, this invention adopts a modular layout, facilitating expansion and maintenance. The facility is equipped with an advanced water treatment system that effectively filters and recycles water, reducing water waste. In conclusion, this invention not only solves many drawbacks of traditional pond aquaculture but also provides a strong guarantee for the efficient, environmentally friendly, and sustainable development of largemouth bass.
