This utility model discloses a bloodworm breeding pond, relating to the field of bloodworm breeding technology. The technical solution includes: a pond body with a pad fixedly fitted onto its exterior, and an L-shaped plate fixedly connected to the bottom of the pad; a U-shaped pipe fixedly connected to the top of the pad, and multiple aeration stones fixedly connected to the inner wall of the pond body, each aeration stone being fixedly connected to the U-shaped pipe via a pipe; and an air pump fixedly connected to the L-shaped plate, with a second pipe fixedly connected to the air pump and the first pipe. The beneficial effects of this utility model are: the design of the air pump, second pipe, U-shaped pipe, first pipe, and aeration stones allows air to enter the aeration stones under the action of the second pipe, U-shaped pipe, and first pipe. This releases air evenly into the water in the form of tiny bubbles, increasing dissolved oxygen levels and improving oxygenation efficiency, providing sufficient oxygen for the bloodworms. Thus, this device possesses an oxygenation function.

This invention relates to the field of aquaculture technology and discloses a large-scale silver carp and bighead carp seedling cultivation equipment, including a cultivation net cage. A support frame one is installed near the top of the inner wall of the cultivation net cage, and a support frame two is installed near the bottom of the inner wall of the cultivation net cage. A partition net is installed between the inner wall of the support frame two and the inner wall of the cultivation net cage. An oxygen distribution mechanism for uniform oxygen distribution is provided inside the cultivation net cage. The oxygen distribution mechanism includes an oxygenation drive component and an oxygen distribution component. This invention, by setting a differentially rotating oxygen delivery main pipe and a fan-shaped blocking plate, can intermittently block the first oxygen delivery nozzle, causing the internal air pressure of the oxygen delivery branch pipe to periodically increase. This significantly increases the air output rate of the second oxygen delivery nozzle and the nozzle branch pipe, effectively enhancing the oxygen supply intensity near the outer water area of ​​the cultivation net cage. It specifically compensates for the low dissolved oxygen in the outer water body due to its distance from the air source, greatly improving the uniformity of oxygen distribution throughout the entire net cage area.

The application discloses an oxygen-increasing and current-creating device, and belongs to the technical field of water oxygen-increasing and current-creating equipment. The device comprises an oxygen-increasing assembly and a current-creating assembly. The oxygen-increasing assembly comprises a high-pressure water flow pushing device. The water outlet end of the high-pressure water flow pushing device is connected with a micro-nano bubble generator. The water outlet end of the micro-nano bubble generator is connected with a micro-nano bubble releaser. The micro-nano bubble generator is connected with an air pipe. The air inlet end of the air pipe is located on the water surface. A plurality of driving paddle wheels are uniformly arranged on the middle part of the driving shaft along the circumferential direction of the driving shaft, so that the high-pressure water flow passing through the micro-nano bubble releaser is sprayed to the plurality of driving paddle wheels in sequence. The structure of the micro-nano bubble generator and the micro-nano bubble releaser is adopted to realize the efficient dissolution of air and high-pressure water flow. The driving paddle wheels are driven to rotate the driven paddle wheels, centrifugal force is formed to drive the water body to rotate, the backflow effect of the backflow cover is coordinated, the surrounding water body is driven to form an overall circulation, and the water body is activated uniformly.
