Loach cultivation ring with screen device

Abstract

The invention provides a loach cultivation ring with a screen device. The loach cultivation ring comprises a vertical column, an upper support component, a protecting net, a cultivation ring, discs, ribbons, a pulley, a fishing net, a power rope, a pothook, a zipper, a filtering plate, steam stones and a water draining hole, wherein the upper support component is arranged above the vertical column; the protecting net is positioned by the vertical column and the upper support component; the discs and the ribbons are uniformly distributed on the top and periphery of the protecting net; the pulley is fixed on the upper support component; the power rope is used for connecting the pulley and the fishing net; the pothook is located on the upper part on one side of the protecting net; the zipper is located under the pothook; the filtering plate is located above the bottom of the cultivation ring; the steam stones are uniformly distributed above the filtering plate; the water draining hole is located at the center of the bottom of the cultivation ring. Due to the arrangement of the loach cultivation ring with the screen device, the catching hazard of the waterfowls eating fish and prawns, such as egret, can be effectively prevented, the detaching and replacement are convenient, the fishing is convenient and quick and the loach cultivation ring is environment-friendly and hygienic.

Description

technical field [0001] The invention belongs to the technical field of loach breeding, in particular to a loach breeding pen with a net cover device. Background technique [0002] Along with the adjustment of the rural industry, the loach aquaculture industry has developed rapidly, and the commercial loach has already occupied a place in the market, but the loach is often harmed by predation by water birds such as egrets that feed on fish and shrimp, which not only causes a large number of pond breeding objects to be injured and died, but also Water birds also spread diseases and cause harm, and most water birds are national protected animals and cannot be culled. At present, the main methods of preventing bird damage are driving, such as manual driving, facility driving, or firecrackers, tweeters or drugs. These are not only easy to cause Environmental pollution and noise pollution are also likely to cause harm to birds. [0003] Therefore, it is very necessary to invent a...
