Abstract

The invention relates to a land-based crab breeding device. The land-based crab breeding device consists of one layer of row cages or is formed by overlapping more than two layers of row cages, wherein each layer of raw cages consists of one crab cage or is formed by connecting more than two crab cages in series through the sides; run-through holes at the corresponding position of the side of each layer of crab cages are positioned on the same straight line; three groups of run-through holes for connecting a water supply pipe, an air supply pipe and a blowdown pipe are formed on the sides of the crab cages; discharge holes are formed on the bottom surfaces of the crab cages; the water supply pipe, the air supply pipe and the discharge pipe transversely pass through the three groups of run-through holes of each layer of crab cages below the top layer of crab cages correspondingly; the water supply pipe and the air supply pipe are communicated with each crab cage through a three-way connector; the discharge pipe in each crab cage is communicated with the discharge hole at the bottom of the previous layer of crab cages through the vertical end of a T-shaped three-way connector; control valves are arranged on the water supply pipes, the air supply pipes and the discharge pipes; and airflow and water circulation in the crab breeding device is controlled by adjusting the control valves arranged on the water supply pipes, the air supply pipes and the discharge pipes.

Description

technical field [0001] The invention relates to a crab raising device suitable for land-based culture of aquatic economic crabs, and also relates to a crab raising method for aquaculture economic crabs by using the crab raising device. Background technique [0002] Economic crabs, such as blue crabs and portunus trituberculatus, are large-scale marine crabs. They are traditional rare and precious cultured species, and they are also an important part of the mariculture industry. Portunus trituberculatus, Portun-us trituberculatus, is widely distributed in sea areas of my country, Japan and Korea. Portunus trituberculatus has delicate meat and delicious taste. According to the analysis of the Chinese Academy of Preventive Medicine and other units, Portunus trituberculatus is rich in various high-protein substances and multi-vitamins. It is not only delicious to eat, but also can be used as medicine as a tonic. The region, Hong Kong, and Macao have been listed as seafood produ...
