[0002] Integrated fishery and photovoltaic is a production method that combines aquaculture and photovoltaic power generation industries. That is, while carrying out aquaculture in the pond water body, photovoltaic modules are erected on the water surface for solar power generation, which can make full use of land and space resources to achieve a triple harvest of fish, electricity, and environmental protection. Compared with traditional power generation, the integrated fishery and photovoltaic mode can reduce carbon emissions in terms of energy conservation, emission reduction, consumption reduction, and ecology.

[0003] The traditional integrated fishery and photovoltaic mode uses fixed pile foundations to erect photovoltaic panels. For example, an integrated fishery and photovoltaic aquaculture system disclosed in Chinese Utility Model Patent CN216821335U (Publication Date: June 28, 2022), the photovoltaic part is arranged in the pond. The photovoltaic part includes a number of photovoltaic modules arranged in sequence. Each photovoltaic module includes two photovoltaic panels, and the two photovoltaic panels are connected by a connecting piece, and the two photovoltaic panels are detachably connected to the connecting piece. The bottom end of the connecting piece is fixedly connected with a base, and the two photovoltaic panels are fixed in the pond through the connecting piece and the base. The traditional integrated fishery and photovoltaic mode has a large density of photovoltaic pile foundations, which is not conducive to fishery production operations. At the same time, the tail water treatment of fishery aquaculture has not been recycled to the maximum extent to achieve the goal of low-carbon emission reduction. Summary of the Utility Model

[0004] To solve the above deficiencies in the prior art, the utility model provides an integrated fishery and photovoltaic low-carbon aquaculture system to reduce the negative impact of the large density of fixed pile foundations in the traditional integrated fishery and photovoltaic on fishery.

[0008] Preferably, the span between adjacent two rows of pile foundations of the flexible photovoltaic support is within the range of 40 - 60 meters.

[0009] Further, a comprehensive rice-fish farming area is provided on one side of the integrated fish and photovoltaic pond. The comprehensive rice-fish farming area is provided with ditches and a rice planting area. The integrated fish and photovoltaic pond is provided with a drainage pipeline connecting to the comprehensive rice-fish farming area.

[0010] Further, it also includes a aquaculture tail water treatment area, which is arranged between the integrated fish and photovoltaic pond and the comprehensive rice-fish farming area.

[0015] The beneficial effects of the present utility model are as follows:

[0016] For the integrated fish and photovoltaic low-carbon aquaculture system of the present utility model, a flexible photovoltaic support is used for the erection of photovoltaic modules, optimizing the traditional fixed pile foundation of the integrated fish and photovoltaic system and reducing the number of pile foundations. At the same time, using a flexible photovoltaic support can conveniently increase the distance between the erected photovoltaic modules and the pond, improving the clear height of the pond.

[0017] For the integrated fish and photovoltaic low-carbon aquaculture system of the present utility model, the aquaculture tail water in the integrated fish and photovoltaic pond is used for irrigating paddy fields. A large amount of nutrients such as nitrogen, phosphorus, and potassium are contained in the feces of fish. These nutrients can be decomposed by microorganisms and converted into organic fertilizers required by plants, thus providing nutrients for rice. At the same time, the microorganisms in the fish feces can also promote the activities of microorganisms in the soil, improving soil fertility and biodiversity. Using fish feces for rice planting can achieve the circular utilization of organic agriculture and realize low-carbon aquaculture. Description of the Drawings

[0025] Flexible photovoltaic brackets are used to replace the original fixed photovoltaic brackets to reduce the number of photovoltaic piles in the integrated fish-light pond. In addition, according to the pond conditions, the flexible photovoltaic brackets are set at 40-60 meters per span, and the piles are driven on the pond bank as much as possible to reduce the impact of the piles on the fishery. The integrated fish-light pond is preferably suitable for aquaculture species such as shrimp, crab, sea cucumber and other shade-loving aquatic animals. The water temperature of the integrated fish-light pond is 1-3℃ lower than that of ordinary ponds. Therefore, in spring, the depth of water added to the integrated fish-light pond is 10-20cm lower than that of ordinary ponds, which is conducive to the warming of the pond and reduces the impact of photovoltaic module shading on the fishery.

[0026] Furthermore, a rice-fish integrated breeding area 4 is provided on one side of the integrated fish-light pond 1, and a field ditch 5 and a rice planting area 6 are provided in the integrated rice-fish breeding area 4.
