Problems solved by technology

However, there are many deficiencies in the traditional net cage culture: traditional net cages mostly use nodular mesh, which uses a lot of materials and the nodules are easy to scratch the skin of rice field eels, and once the nodular net is damaged, the mesh will become loose; The net cage is large in size and the water surface is deep, so eels are not easy to domesticate; the net cage touches the bottom of the pond, causing some residual feed and eel excrement to accumulate in the water body, and these substances are easily decomposed in the anoxic environment of the lower water body to produce amines, nitrogen, and nitrous acid Nitrogen and other substances are not only harmful to ricefield eels, but also pollute the environment and affect water exchange

Embodiment 1

[0026] A rice field eel breeding net cage, 2 meters long, 2 meters wide, and 1 meter high, comprising four net walls 1 and a net bottom 2 composed of net sheets, the net walls 1 and net walls 1 and the net walls of the net cage 1 and the bottom of the net 2 are sewed firmly with two nylon threads, wherein the tops of the two relative net walls 1 have bar-shaped iron wire 3 structures, and the iron wires 3 pass through the mesh on the top, and are used to fix the net cage on the net. on supports in ponds. The rhombus mesh size is 0.8 mesh, and the adjacent angles are 90° and 90°. There are nylon fixing belts at the four corners of the net cage, and the net cage is fixed on the moso bamboo in the pond.

Embodiment 2

[0028] A rice field eel breeding net cage, 3 meters long, 3 meters wide, and 1 meter high, comprising four net walls 1 and a net bottom 2 composed of net sheets, the net walls 1 and net walls 1 and the net walls of the net cage 1 and the bottom of the net 2 are sewed firmly with two nylon sutures, and the top of the four net walls has a strip-shaped iron wire 3 structure, and the iron wire 3 passes through the mesh on the top to fix the net cage on the support in the pond superior. The rhombus mesh size is 0.6 mesh, and the adjacent angles are 85° and 95°. There are nylon fixing belts at the four corners of the net cage, and the net cage is fixed on the moso bamboo in the pond.

[0029] Through the implementation of the above embodiments, this invention uses less material for the mesh sheet and has little damage to the eel; the mesh is fully opened, the volume of the cage is relatively increased, and the frequency of water exchange is improved; the accumulation of residual fe...

Abstract

The invention relates to a finless eel farming facility, in particular to a finless eel farming net cage. The net cage comprises a net wall and a net bottom formed by meshes and adopts a polyvinyl material, wherein bar-shaped connecting components used for fixing the net cage are arranged at the top ends of at least two opposite net walls, the net cage is a cuboid-shaped net cage without nodules, the wire mesh sieve number of each mesh is 0.6-0.8. The net cage facilities the gas exchange in the net cage, reduces accumulation of the residue fodder and excrement of finless eels, reduces occurrence of diseases of the finless eels, and improves the yield.

Description

technical field [0001] The invention relates to a ricefield eel breeding facility, in particular to a ricefield eel breeding cage. Background technique [0002] Cage culture of rice field eel is a farming method with low investment, quick results and convenient management, which is widely adopted by rice field eel farmers. However, there are many deficiencies in the traditional net cage culture: traditional net cages mostly use nodular mesh, which uses a lot of materials and the nodules are easy to scratch the skin of rice field eels, and once the nodular net is damaged, the mesh will become loose; The net cage is large in size and the water surface is deep, so eels are not easy to domesticate; the net cage touches the bottom of the pond, causing some residual feed and eel excrement to accumulate in the water body, and these substances are easily decomposed in the anoxic environment of the lower water body to produce amines, nitrogen, and nitrous acid Substances such as nit...
