People can often be seen raising fish in the runway of the pond. Is it really appropriate to raise fish on the pond runway?

Compared with traditional fish ponds, runway fish farming is a big step forward! Whether it is productivity, feeding cost, environmental protection, management and other aspects, the traditional fish farming model is crushed! Pond runways or so-called circulating fish farming in ponds are all pure lines. If there are funds for the construction of runway facilities, it is best to build sewage discharge and water convection, and strengthen the overall oxygen supply system in the pool. By collecting aquaculture waste, the problems of eutrophication and pollution of aquaculture water are effectively solved, and the collected fish manure and residual bait can be used as organic bio-fertilizer to realize the resource utilization of waste; It is a new model of environmental protection pond culture with sustainable ecological cycle.

Have you ever touched the runway to raise fish? How are the various conclusions drawn? Imagination or reasoning? I hope that some practitioners who have been engaged in runway farming or similar high-density farming will give objective opinions. Water quality purification system of peripheral pond: plant submerged or emergent plants, stock aquatic animals such as silver carp, loach, snail and freshwater shrimp, and purify the water body. The water surface of peripheral pond is equipped with air-lift water pushing facilities.

Using runway to build pollution absorption device, because the density of runway culture is generally high, it is necessary to avoid the aggravation of pollution in the process of breeding. The shape and direction of the pond. The pond is rectangular in shape. The length-width ratio is 2-3: 1 and the width is 30-50m, which is convenient for management and trawling. The direction of the pond should be east-west, which is conducive to extending the sunshine time.

Fish is an animal that lives in water for a long time. Fish can be divided into riffraff fish, middle-class fish and upper-class fish. In order to ensure the comprehensive utilization of water and feed in the same water environment, reduce the feeding cost and improve the production efficiency, professional fish ponds are suitable for breeding silver carp, bighead carp, carp and crucian carp. Silver carp, bighead carp, carp and crucian carp are three kinds of fish, which can save feed and enrich water and ponds for fish growth. In winter and spring, it is necessary to store water deep, and it is just about one meter by the pond weir.
