Description

Technical Field

[0001] The utility model relates to the field of rice field crayfish breeding, in particular to a field fixed-point collecting and catching device for rice field crayfish. Background Art

[0002] At present, crayfish, scientifically known as Procambarus clarkii, also known as red crayfish and freshwater crayfish, is an important freshwater economic shrimp. Crayfish is bright red after being cooked, which stimulates appetite. In addition, it is spicy and delicious, and its meat is tender and smooth. It has quickly become the main dish on the table from a traditional midnight snack, and is widely welcomed by consumers.

[0003] At present, the crayfish cultured in rice fields are caught in the form of ground cages or artificial nets. The artificial net method is inefficient and labor-intensive. Fishing with ground cages requires regular inspection to prevent the ground cages from being too full and affecting the fishing effect. Most lobster farmers now use ground cages for harvesting. Application number: CN201720587234.X A lobster ground cage, including a ground cage front section, a ground cage rear section, a ground cage net and a rectangular frame. The ground cage nets of the front section and the rear section of the ground cage are connected by a zipper. The top surface of the rear section of the ground cage and the ground cage net between the two rectangular frames are provided with holes, and the holes are covered with mesh; a screen is sewn at one end of the front section of the ground cage away from the rear section of the ground cage, and a plastic bucket is connected to the screen away from the front section of the ground cage. A plurality of limit rings are fixed on the top of the cover and the tail end of the plastic bucket, and a fixing rod is inserted into the limit ring, and a limit block is fixed on the fixing rod.
