Problems solved by technology

The main reason is that the utilization rate of crab breeding space is low, the phenomenon of mutual killing is serious, and the breeding method needs to be broken through urgently.
However, there is currently no suitable device for floating rafts used for crab water surface cultivation, and there is a lack of suitable connecting tools between the floating rafts, so it is not easy to arrange and manage them uniformly

Abstract

The invention relates to a crab cage culture module with a connecting device and a system thereof. The crab cage culture module comprises a crab cage and a buoy device. The buoy device comprises a short edge barrel, a long edge barrel and a quarter turn joint. The short edge barrel and the long edge barrel form a rectangular frame through the quarter turn joint. Connecting locking devices for being connected with a plurality of crab cage culture modules are installed on a long edge and a short edge of the rectangular frame, and the crab cage is installed in the rectangular frame. The system is formed by the plurality of crab cage culture modules which are shaped like a Chinese character ao. When the crab cage culture module and the system are used for cultivation, centralized and unified processing is greatly facilitated, the survival rate of crabs is improved, and acre yield is increased by several times.

Description

technical field [0001] The invention relates to the technical field of crab breeding tools, in particular to a crab cage breeding module with a connecting device and a system thereof. Background technique [0002] Crab is one of the important aquatic products in our country. It is loved by everyone because of its delicious meat and rich nutrition. However, due to the low yield per unit area of ​​its breeding area and high killing rate, it is easy to be infected with germs, and the survival rate is low, so it is difficult to breed. Especially for blue crabs and swimming crabs, which are common species in marine culture in China, the survival rate of crabs under traditional farming methods is 10-20%, and the per unit yield is only 50-150 kg / mu, which is far from other cultured species such as prawns. The main reason is that the utilization rate of crab breeding space is low, the phenomenon of mutual killing is serious, and the breeding method needs to be broken. And the floa...
