The outer pond is sparkling, and the water flow in the four fish tanks in the pond is gurgling. A water pusher is operating at the front end of each tank. There are multiple oxygen increasing pipes in the middle to supply oxygen. At the other end is a dirt suction device, which moves left and right to absorb the residual feed and fish excrement at the bottom of the tank.
Recently, many breeding friends have shown great interest in the new mode of circulating water in ponds. Because of the advantages of high yield, low pollution and low cost, the breeding mode has been widely recognized in various places.
Recently, many small partners have actively asked Xinjiang Fisheries about the scale, cost, variety and so on of circulating water fish culture in ponds. In response to the various questions raised by the relatives, the expert group summarized the following points. Little friends, come and watch and learn!
What kind of pond is suitable for the construction of circulating water system
The centralized fish culture area accounts for 1.5-3% of the total area of the pond. The size of the pond is preferably above 25 mu of water surface and the water depth is not less than 1.8-2 meters. The water surface is too small than the shallow water biological system is not rich, the overall water quality purification effect is poor, and then restrict the production.
