Abstract

The invention relates to a device and a method for cycling aerated water in a parent fish rearing pond. The device comprises an elbow, a main tube and a base, wherein the elbow is coaxially sheathed onto the main tube; the lower end of the main tube is fixed onto the base by using a cotton rope; first holes are evenly distributed at the upper end of the main tube around a tube body; second holes are distributed at the lower end of the main tube around the tube body; the elbow and the main tube are respectively made of (polyvinyl chloride) PVC tubing; the height of the main tube is 40cm; the diameter of the main tube is 9cm; the elbow is a 90-degree elbow assorted with the main tube; the base is made of smooth cement square bricks; and the second holes are evenly arranged or randomly arranged around the main tube. In the method, after the device is connected, oxygenation heads are respectively arranged in the first holes, and the number of the first holes and the second holes can be changed according to the bearing capacity of the tubing. The device and the method for cycling the aerated water in the parent fish rearing pond are capable of implementing water flow stimulation on parent fishes to ensure a water body to have high flowability, thereby being beneficial to collecting remnant feeds and excrements. Simultaneously, the device and the method for cycling the aerated waterin the parent fish rearing pond are simple to operate and are easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a device and method for inflating water circulation in a broodstock breeding pond. Background technique [0002] In factory farming, square or circular cement pools and glass fiber reinforced plastics are generally used as breeding pools or holding pools for broodstock. The square pool has the advantages of easy arrangement, high site utilization rate and large water body. However, the square pool has the disadvantages of poor water fluidity, uneven water quality, and difficult sewage discharge. The indoor utilization rate of the circular pool is lower than that of the square pool, but it has the characteristics of reasonable structure, good dynamic balance of water flow, relatively easy to collect sewage, and convenient management. In the process of industrial farming, the content of dissolved oxygen in the farming water is particularly important. At present, ...
