Embodiment 1

[0018] refer to Figure 1 ~ Figure 3 , a method for making a ground cage for fishing large-scale freshwater shrimp, the method for making comprises the following steps:

[0019] 1) The mesh bag unit 1 is made of a mesh with a side length of 3-5 mm, and the adjacent mesh bag units 1 are separated and supported by keels to form a barreled mesh bag 2;

[0020] 2) Both ends of the barreled mesh bag 2 are equipped with a shrimp collection unit 3, the shrimp collection unit 3 includes a shrimp collection unit 4, and the shrimp collection unit 4 adopts a mesh with a side length of 6-10mm. The mesh wire of unit 4 is thicker than the mesh wire of the mesh bag unit.

[0021] Further, the shrimp collecting unit 3 includes at least two shrimp collecting units, and adjacent shrimp collecting units are separated and supported by keels.

[0022] The barreled mesh bag 2 includes 8 to 20 mesh bag units, and the length of each mesh bag unit is 10 to 20 cm.

[0023] The length of the shrimp c...

Abstract

The invention discloses a manufacture method for a ground cage used for fishing big-size freshwater shrimps. The manufacture method comprises the following steps of: (1) manufacturing mesh bag units by meshes of which the side length is 3-5mm, separating and supporting adjacent mesh bag units by a keel to form a barrel mesh bag; and (2) installing a shrimp collection part respectively on two ends of the barrel mesh bag, wherein the shrimp collection part comprises a shrimp collection unit adopting the meshes of which the side length is 6-10mm, and the mesh wire of the shrimp collection unit is thicker than the mesh wire of the mesh bag unit. The invention also provides a ground cage manufactured with the method. According to the invention, the use cost is lowered, and the manual sorting intensity is lightened.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a method for making a ground cage for fishing freshwater shrimp and the ground cage. Background technique [0002] In the prior art, the method for catching crustaceans mostly adopts ground cages to catch in batches. For freshwater shrimp fishing, in the past, ground cage fishing was often used, followed by mechanical or manual grading and screening, and then sold according to different specifications. However, this screening process often inevitably causes some damage to the freshwater shrimp, which causes infection and affects the survival rate during transportation. In the ground cages that have been adopted, there is often no part of the shrimp collection part, and the mesh size of the entire ground cage is the same, resulting in the capture of many shrimps with insufficient specifications. However, this part of the shrimp is caught because of the long first step. Because...
