A fish blocking device based on paddy field fish farming

Abstract

The invention discloses a fish screen device based on rice field fish culture. The fish screen device comprises a fish-culture fish screen device, wherein the fish-culture fish screen device comprisesfish screen rods, tops of the fish screen rods are fixedly connected with a fixing station, the top of the fixing station is fixedly connected with middle rods, tops of the middle rods are fixedly connected with limiting top caps, two insertion ports are separately formed inside each fish screen rod, and a fish screen outer plate and a fish screen inner plate are separately inserted inside the corresponding two insertion ports. According to the fish screen device based on rice field fish culture, through the matching among a fish screen inner mesh, a fish screen outer mesh and a fish screen side mesh, fishes in the fish-culture fish screen device are intercepted and are prevented from leaving a culture circle, and thus, the balance of a system is destroyed; and through the matching amongthe meshes, the intercepting effect is improved, cultured fishes are prevented from leaving the culture circle, the advantage of facilitating fish screen is achieved, and the problem of the existing rice field fish culture that the fishes easily leave a culture range, thus, the quantity of the fishes is reduced, thus, the balance of a rice field fish culture system is destroyed, and the yield is reduced is solved.

Description

technical field

[0001] The invention relates to the technical field of paddy-field fish farming, in particular to a fish-stopping device for paddy-field-based fish farming. Background technique

[0002] Fish farming in rice fields is to raise fish on the water surface of rice fields. It can not only obtain fish products, but also use fish to eat pests and weeds in rice fields, excrete manure, turn soil to promote fertilizer decomposition, and create good conditions for rice growth. Increase production by about 10%.

[0003] In the existing rice field fish farming, because the fish will wander with the water during the fish farming process, it is easy to leave the farming range, thereby reducing the number of farmed fish and reducing the output of farmed fish, thereby affecting the balance of the rice field fish farming system. Thereby reducing the production of fish and rice fields. Contents of the invention
