Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to an integrated circulating water fish fry cultivation system. Background Art

[0002] The breeding conditions of fish fry greatly affect the subsequent results of adult fish breeding. At present, most farmers purchase large-sized seedlings from others for centralized breeding. The quality of purchased seedlings is difficult to evaluate, and the price of seedlings is higher than that of self-breeding. At the same time, species such as California bass, which need to be released in the same year, are in short supply due to climate restrictions, technical restrictions, infrastructure and equipment and other factors. The farmers' year-round breeding plans are seriously affected, which is very unfriendly to small farmers. The basic factor affecting the effect of fish fry breeding is mainly the water quality of the breeding water body. At present, more and more species and more and more farmers use the factory-scale circulating water model for fish fry breeding. This is because factory-scale circulating water breeding has the advantages of stable and controllable water quality, reduced diseases, healthier fry, and off-season seedling cultivation.

[0003] The recirculating aquaculture system has been rapidly developed and applied at home and abroad due to its advantages of water saving, land saving, high-density intensiveness, and controllable emissions. At present, the recirculating aquaculture system is mainly used for adult fish farming and large-scale seedling cultivation. Most of the system designs divide the water treatment system and the breeding system into two parts, and use running water or water exchange to circulate the water. The system heating cost is high. At the same time, under the conditions of water exchange or running water, the water environment is unstable; good remote water conditions are required, such as a stable water source and a reservoir with sufficient volume; the breeding unit and the water treatment unit are separated, and the water volume of a single system is large, the construction cost is high, and it is difficult to move and transport. At the same time, it requires a corresponding area of ​​land and needs to be manufactured and installed on site at the project site. It is more suitable for large-scale breeding enterprises and specialized seedling production enterprises. Therefore, its actual application ability is affected to a certain extent, limiting its further promotion. Utility Model Content
