Fish fry culturing pond oxygenation system

Abstract

The invention provides a fish fry culturing pond oxygenation system comprising a control module, an ultraviolet sterilization device, a culturing pond, a sewage discharge pond, an air compressor, an oxygen generation machine, and a water body oxygenation machine. The control module is connected with the ultraviolet sterilization device and the air compressor. The water body oxygenation machine is connected with the ultraviolet sterilization device. The air compressor is connected with the oxygen generation machine. The oxygen generation machine is connected with the culturing pond. The sewage discharge pond is connected with the culturing pond. The system provided by the invention has the following advantage: with the system, culturing pond sterilization and oxygenation capacities are effectively improved. A biological pond has a purification function, and a water replenishment high-level pond is used for replenishing water in the biological pond, such that an entire set of fry culturing pond water circulation system is formed, and the fish fry survival rate is improved.

Description

【Technical field】 [0001] The invention belongs to the field of seed breeding, and in particular relates to an aeration system for a fry breeding pond. 【Background technique】 [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and ...

AI Technical Summary

Problems solved by technology

[0003] In the high-density intensive fish fry culture, it is necessary to discharge the backwater with dirt in the culture pond and inject new water into the culture pond, which has achieved the purpose of saving water and maintaining the breeding environment. The existing fish fry cultivation process is disinfected and oxygenated The ability is poor, so the survival rate of fish fry is not high, and the sewage discharger of the existing aquaculture pond is easy to block the sewage outlet, which is not conducive to sewage discharge
