Embodiment 1

[0025] Aquaculture water recycling system, the system includes a finished fish breeding area 2, an exposed algae growing area 3, a water fish functional area 5, an aquatic crop planting area 6, a sand filter area 7 and a reservoir 8 that are connected in sequence in a cycle , wherein a water inlet 1 is provided on the communication pipeline between the finished fish culture area 2 and the reservoir 8; the exposed algae growing area 3 is provided with a back-shaped groove 4, and the back-shaped groove 4 is separated by at least one partition plate 12 and A repeatedly folded S-shaped channel is formed.

[0026] A groove 9 is formed between the partition plates 12 in the back-shaped groove 4 . A floating plate 10 and a mesh sheet 11 are spaced above the groove 9 , and the floating plate 10 and the mesh sheet 11 are fixedly connected to the partition plate 12 .

[0027] The upper opening of the water fish functional area 5 is square, and the bottom is inverted conical, which inclu...

Embodiment 2

[0036] Adopt the system described in Example 1 to carry out aquaculture, and the parameters of the system are as follows:

[0037]Finished fish breeding area 2: 4 ponds of 2 mu each, with a depth of 1.8 meters, intensively rearing commercial largemouth bass, with 3,500 fish species per mu. In the past year, commercial fish need to be fed with a large amount of commercial feed. Metabolism and excrement cause organic pollution to the water quality. After a period of cultivation, the pond water needs to be filled with new water, and one-third of the old water is discharged from the other end, once every 6 days or so.

[0038] Exposure algae growing area 3: The groove is 1 meter deep and 1 meter wide and has a total length of 2000 meters. It receives the pond water discharged from the finished fish breeding area 2. The exposed algae growing area 3 is a long and narrow loop-shaped groove 4 that is folded repeatedly. The purpose is to make it as far as possible. Long to increase the...

Abstract

The invention discloses an aquaculture water body cyclic utilization system. The aquaculture water body cyclic utilization system comprises product fish culturing regions, an exposure algae generatingregion, a water feeding fish function region, an aquatic crop planting region, a sand filtering region and a water reservoir which are in sequential communication in a cycle manner, wherein a water inlet is formed in a pipeline enabling the product fish culturing regions and the water reservoir to be in communication; and a trench in the shape of a Chinese character "hui" is formed in the exposure algae generating region, is separated by one or more partition plates and forms an S-shaped channel which is folded repeatedly. Compared with the prior art, the aquaculture water body cyclic utilization system has the following advantages that the system solves the difficult problem of eutrophication of a water body in the aquaculture process, and achieves the purpose of comprehensive utilization of breeding waste water; the system not only can improve the quality of culture water, but also can produce various industrial agriculture products and can improve the product quality; and the system is friendly to surrounding environment, low in production cost, low in risks, low in operation cost, easy to construct and reform, easy to control and flexible in manner.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a device for comprehensive utilization of water bodies in high-density aquaculture ponds, in particular to an aquaculture water body recycling system. Background technique [0002] In the process of pond culture, due to a large amount of feed, resulting in excessive nitrogen, phosphorus and other nutrients and organic matter in the water body, insufficient dissolved oxygen often occurs, slow growth of fish, serious outbreaks of fish diseases, and decreased survival rate, which in turn leads to finished fish. Quality and taste are greatly affected. Especially in Laokou Pond, the above situation is more serious. At present, some areas have improved the breeding environment by injecting and draining water, and some areas have maintained the pond environment by using a large number of water transfer reagents and drugs. However, the living environment of breeding has become more an...
