Freshwater shrimp catching cage device for shoals

Abstract

The invention relates to a freshwater shrimp catching cage device for shoals. The cage device comprises a cage body skeleton, wherein the cage body skeleton is formed through welding steel-bar upright columns, outer side faces of the cage body skeleton are wrapped with netting walls so as to form a circular cage body, five shrimp inlets are respectively formed in the top and circumference of the cage body, steel-bar barbs are respectively mounted on the five shrimp inlets and are fixed by the netting walls, the two sides of the lower end of the cage body are respectively connected with two shrimp storage bag shrimp inlets and connected with two shrimp storage bags, the shrimp storage bags are fixed by shrimp storage bag netting head ropes, the internal space of each shrimp storage bag is supported by three steel-bar supporting rings and has been extended to a shrimp taking port tightening rope, inner barbs are respectively mounted at the two shrimp storage bag shrimp inlets, extend inwards and are connected with inner barb openings, the inner barb openings are fixed by inner barb opening pull ropes, 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 green prawns, in particular to a cage for catching green prawns in shoals, and belongs to the technical field of cages for catching green prawns. 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 shrimps will run away because they find that the circular net has moved, and the shrimp that escaped due to missing catch will b...

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 shrimps 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 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.
