Antifouling and anti-biting cultivation net cage of huangsha (Chinese character) turtle

Abstract

The invention discloses an antifouling and anti-biting cultivation cage of a huangsha (Chinese character) turtle. The antifouling and anti-biting cultivation net cage comprises a cage body top part, cage sides and a cage bottom. The antifouling and anti-biting cultivation cage is characterized in that the top part of the cage body adopts an anti-biting small-screen ultra-high molecular weight polyethylene net to be sutured into an annular net; the cage side adopts a combined net formed by a copper alloy woven mesh, a netting half-soft state connection, the copper alloy woven mesh, the netting half-soft state connection, the copper alloy woven mesh, the netting half-soft state connection, the copper alloy woven mesh, the netting half-soft state connection and a nylon mesh; a foam floater is arranged on an upper middle line of the copper alloy woven mesh as a buoyancy system; the cage bottom adopts the combined netting of a nylon woven mesh and the copper alloy woven mesh; a cylindrical heavy block is respectively suspended at four corners of the box body for the cage; a back sunning table is arranged inside the cage; the cross section of the back sunning table is an isosceles trapezoid; the distance from an upper bottom to a lower bottom of the isosceles trapezoid is 30cm; and the part of the back sunning table, in the water, is 16-20cm in vertical height, and the cage is fastened on a fixed parking system of an aquaculture area by a connection rope.

Description

technical field [0001] The invention relates to an anti-pollution and anti-bite breeding net cage, in particular to a net cage for cultivating yellow sand soft-shelled turtles. Background technique [0002] Yellow sand soft-shelled soft-shelled soft-shelled turtle is a local strain of Chinese soft-shelled turtle. It is rich in nutrition and delicious in taste. It is a treasure in fresh water and a nutritional tonic favored by people. Yellow sand soft-shelled soft-shelled turtles generally use soft-shelled turtle ponds or cages with synthetic fiber netting. Synthetic fiber netting net cages often suffer from rodent damage during breeding. After the rats bite through the synthetic fiber netting net cages used for the breeding of yellow sand soft-shelled turtles, the nets will break and the soft-shelled turtles will escape, causing economic losses to the yellow sand soft-shelled turtle farmers; The fouling and adhesion of fiber net cages in culture is very serious, resulting i...

AI Technical Summary

Problems solved by technology

Synthetic fiber netting net cages often suffer from rodent damage during breeding. After the rats bite through the synthetic fiber netting net cages used for the breeding of yellow sand soft-shelled turtles, the nets will break and the soft-shelled turtles will escape, causing economic losses to the yellow sand soft-shelled turtle farmers; Fiber net cages are very seriously fouled and adhered during cultivation, resulting in more frequent net changes, greater labor intensity for net changes, and unsmooth water exchange inside and outside the cage, which affects the normal growth and development of the yellow sand soft-shelled turtle. Quality and comprehensive cage culture benefits

Turtle ponds are also used for breeding yellow sand soft-shelled turtles. Not only the construction cost of turtle ponds is high, but also the cultivation of turtle ponds may waste land resources or artificially destroy the ecological environment of the breeding sites; Problems such as inconvenient or poor water flow in turtle ponds affect the quality, growth and breeding efficiency of yellow sand soft-shelled turtles
