Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0017] Such as Figure 1-2 As shown, a concealment for cultivating red-clawed crayfish of the present invention includes a PVC pipe body, a connecting rope and a float. The float is set; the PVC pipe body is formed by sticking a plurality of PVC pipes.
[0018] When the present invention is implemented in practice, the PVC pipe body is formed by sticking PVC pipes with an inner diameter of 5 cm and a length of 15-20 cm. The glued PVC pipes are glued to each other through the outer walls. Glue into regular triangle among this example, the PVC pipe...

The invention relates to a concealed object for breeding red crayfish and a using method. The concealed object of the invention comprises PVC pipe bodies, a connecting rope and a float, the PVC pipe bodies are multiple, are arranged in parallel and are connected in a string through the connecting rope, and one end of the connecting rope is provided with the float; and the PVC pipe body is made ofa plurality of PVC pipes. According to the present invention, through arranging concealed objects in a breeding pond, places for decladding and concealing are provided for red crayfish, and feed feeding is not affected, so that the survival rate and the yield per unit area of red crayfish are improved. The structure of the concealed object is simple, the manufacturing, transportation and storage are convenient, and the survival rate and the yield per unit area of red crayfish can be increased by more than 10%.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a red-clawed crayfish breeding facility, in particular to a concealment and a use method for breeding red-clawed crayfish. Background technique [0002] Commonly known as Australian freshwater lobster, red claw crayfish has the characteristics of fast growth, miscellaneous food habits, strong adaptability, easy breeding and transportation, etc. Its tender meat and delicious taste are deeply loved by consumers. Red claw crayfish has a strong sense of territory, prefers to live in hidden places in water bodies, and has the habit of cannibalism, especially the uneven size and molting, and the survival rate of breeding is low. Before the present invention, the cultured red-clawed crayfish mostly planted aquatic plants at the bottom of the pool or placed bricks, meshes, branches, etc. to provide concealment for the shrimps, so as to reduce cannibalism and improve the survival rate o...
