Specification-controllable rat-proof net bag bucket which is used for lobster ground cage and does not hurt lobsters

Abstract

A specification-controllable rat-proof net bag bucket which is used for a lobster ground cage and does not hurt lobsters comprises an inner bucket and an outer bucket. The lower end of the inner upper bucket with large round holes is connected with the upper end of the inner middle bucket with middle round holes, the lower end of the inner middle bucket with the middle round holes is connected with the upper end of the inner lower bucket with small round holes, one side of the lower end of the inner lower bucket with the small round holes is connected with the outer circle side of the inner bucket fixed bottom with micro round holes, the inner bucket fixed bottom with the micro round holes is in bolt connection with the inner movable bucket bottom with micro round holes, and the inner movable bucket bottom with the micro round holes can be opened or laid flatly under the effect of bolts and can be tightened or loosened through a string, a certain micro round hole formed in the round edge of the inner movable bucket bottom with the micro round holes and a certain round hole of the inner bucket with the small round holes. The lower end of the outer upper jacketing bucket with large round holes is connected with the upper end of the outer middle jacketing bucket with middle round holes, and the lower end of the outer middle jacketing bucket with the middle round holes is round and hollow. The inner bucket and the outer bucket are combined, and the outer sleeve is sleeved by the inner lower bucket with the small round holes. The specification-controllable rat-proof net bag bucket which is used for the lobster ground cage and does not hurt the lobsters has the advantages that hurts brought to lobster during catching are greatly decreased, the yield is improved, and damage caused by rats is effectively prevented.

Description

technical field [0001] The invention belongs to the field of crayfish fishing equipment manufacturing, and in particular relates to a crayfish ground cage with a controllable specification that does not damage shrimp and a rodent-proof net bucket, referred to as the net bucket. Background technique [0002] Crayfish is an important fish and shrimp product cultured in the middle and lower reaches of the Yangtze River. Especially in the Jianghan Plain of Hubei Province, through years of practice, a shrimp-rice co-cropping model has been developed. Large paddy fields can be planted with rice and crayfish can be grown at the same time, which not only provides people with A large amount of delicious crayfish food has also opened up a new field of aquatic products for farmers to increase their income. In the process of co-cropping shrimp and rice, when the crayfish reach the specifications of commercial shrimp, they need to be caught and sold. The current fishing method is to fis...

AI Technical Summary

Problems solved by technology

The current fishing method is to fish in paddy fields with ground cages about 20 meters long. After the crayfish are caught, large, medium and small crayfish of different sizes are mixed and need to be picked manually, or even carefully selected one by one. , when the crayfish that reach the commercial shrimp size are picked out, the shrimp seedlings and small-sized crayfish are put back into the pond. Some shrimp seedlings are put into the ground cage after being put in, and they will be picked again the next day, and so on. There are a lot of artificial injuries, which can easily lead to physical decline, disease, and death of shrimp fry

And reduce the yield, bring losses, and the mesh bags of the cages are often bitten by mice, shrimp farmers have to spend a lot of time and energy every day to repair

There has been no good technical solution for the above-mentioned drawbacks
