Description

Crayfish automatic fishing device

technical field

The invention relates to the technical field of aquatic fishing equipment, in particular to an automatic crayfish fishing device.

Background technique

In recent years, crayfish has been welcomed by consumers and has become one of the favorite delicacies of the public. The annual output of the country is as high as one million tons. China is the main producer of crayfish. The development of the pond, and the labor cost have also increased significantly. Shrimp fishing is one of the important links. The traditional fishing method is still used in the crayfish fishing in the prior art, generally by manual throwing and throwing the ground cage. A lot of manpower and material resources, and the fishing process takes a long time, resulting in an increase in the mortality rate of crayfish, which cannot provide timely and fresh crayfish for the market; if ground cage fishing is used, the length of a shrimp cage is generally more than five meters. Stand by the side of the shrimp pond and throw the ground cage into the shrimp pond. First, ensure the direction of the ground cage, and second, ensure that one end is lifted partly from the water surface, and the end lifted from the water surface is fixed on the shore. When harvesting shrimp, gradually lift the ground cage. Leave the water surface and fold it, and then pour out the crayfish in the ground cage. Each ground cage needs to be operated by the shrimper. For professional crayfish farmers, the breeding area is large, the shrimp is frequently caught, and the amount of shrimp caught in a single time Large, requires huge manpower and material resources, and takes too long. Under high temperature conditions, it is easy to cause dehydration, loss of luster, or even death of crayfish. When lifting the ground cage, the mud is easy to splash on the clothes of the shrimp catcher. Also easily cause fisherman to take place disease when cold, therefore, need a kind of fishing equipment that can replace artificial shrimp now badly.
