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 nettinghalf-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 cylindricalheavy 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 a net cage for cultivating yellow sand 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 in more times of changing nets, greater labor intensity for changing nets, and uns...

Embodiment Construction

[0007] The present invention (referring to accompanying drawing) is made up of net cage box body top, box body side and box bottom, and the net cage box body top adopts and is sewn together by four isosceles trapezoid anti-bite type small mesh ultra-high molecular weight polyethylene net clothes of the same specification. Ring netting 1, wherein the distance between the upper base and the lower base of the isosceles trapezoid is greater than or equal to 0.3m, and the mesh size range of the anti-bite small mesh ultra-high molecular weight polyethylene netting is 4cm-6cm, On the inner ring and the outer ring of the ring-shaped net, respectively assemble the ultra-high molecular weight polyethylene rope with a nominal diameter greater than or equal to 8mm and treated with a water-soluble resin as the inner ring and outer ring of the net at the top of the box; The netting on the side of the cage body is the main component of the netting system of the cage. The netting on the side o...
