Butterfly-shaped inverted whisker freshwater shrimp catching cage device for shoals

Abstract

The invention relates to a butterfly-shaped inverted whisker freshwater shrimp catching cage device for shoals. The cage device comprises a steel-bar framework, wherein outer side faces of the steel-bar framework are wrapped with netting sheets so as to form a cage body, a shrimp storage bag inlet is formed in one side of the steel-bar framework wrapped with the netting sheets and is connected with a shrimp storage bag, the shrimp storage bag is connected and fixed by upper and lower netting head ropes, the internal space of the shrimp storage bag is supported by two steel-bar supporting rings and has been extended to a shrimp taking port tightening rope, the shrimp storage bag inlet is connected with inner inverted whiskers, the inner inverted whiskers extend inwards and are connected with an inner inverted whisker opening, the inner inverted whisker opening is fixed by inner inverted whisker opening pull ropes, shrimp inlets are respectively formed in opposite faces of the two ends of the cage body, butterfly-shaped steel-bar inverted whiskers are mounted on the shrimp inlets and are fixed by the netting sheets, and a shrimp bait bag is arranged at the bottom of the cage body and is fixed by shrimp bait bag pull ropes.

Description

technical field [0001] The invention relates to a cage for catching shrimps, in particular to a cage for catching green shrimps in butterfly-shaped barbel shoals, and belongs to the technical field of cages for catching shrimps. Background technique [0002] Freshwater shrimp like to live in areas with a lot of aquatic plants and rocks at the bottom of the river, and generally cannot be caught with large nets. At present, people generally adopt a kind of circular mesh sheet when catching freshwater shrimp, and it has a circular skeleton, and mesh sheet is arranged on the circular skeleton. When in use, put shrimp food in the center of the circular mesh and put it into the water. When the shrimp enters the center of the circular mesh to eat, lift the net and the shrimp left in the circular mesh will be caught But in the process of lifting the net, some freshwater shrimp will run away because they find that the circular net has moved, and the shrimp that escaped due to missin...

AI Technical Summary

Problems solved by technology

When in use, put shrimp food in the center of the circular mesh and put it into the water. When the shrimp enters the center of the circular mesh to eat, lift the net and the shrimp left in the circular mesh will be caught But in the process of lifting the net, some freshwater shrimp will run away because they find that the circular net has moved, and the shrimp that escaped due to missing catch will be frightened, thus affecting the normal growth of the shrimp. If the circular net is not lifted in time, some full-fledged freshwater shrimp will swim away, wasting the food for attracting shrimp. The use of the shrimp net is labor-intensive, the amount of freshwater prawns caught is small, and the effect of catching freshwater shrimp is poor.
