AI Technical Summary
Technical Problem
The existing net-lifting fishing technology is used to catch fish on large water surfaces, and the fishing cycle is long and the cost is high. There is a lack of physical barriers to effectively retain fishing schools, resulting in a low fishing rate.
Method used
A grass is set up in the fishing device to simulate the natural aquatic and grass environment, and combined with bubble wall technology, it attracts and fixes fish through grass. When catching, it uses bubble wall to drive fish into the net to reduce the escape rate.
Benefits of technology
It improves the fish retention rate, reduces the number of bait feeds and trapping cycles, reduces transportation and deployment costs, and improves fishing efficiency.

Abstract
The invention discloses a fish trapping method with high fish retention rate, which comprises the following steps: grass clusters are arranged in a fish catching device, the fish catching device can adopt a drop net, a plurality of groups of grass clusters are arranged in the drop net, fish schools like to hide in the grass clusters, and fishes like to play and eat in the grass clusters can find small fishes and shrimps to eat in the grass clusters; after entering the drop net, fish schools hide in the grass, the artificial grass simulates a natural aquatic plant environment, attracts the fish schools to stay and inhabit, prolongs the residence time of the fish schools, can reduce the bait feeding frequency, can greatly improve the fish retention rate as long as the bait is fed at proper time in the fishing period, and can provide a sense of safety for the fish schools when the fish schools are frightened during fishing. Meanwhile, a bubble wall is formed on the periphery of the edge of the drop net, so that the vent holes exhaust air to form a barrier, the fish schools are reversely driven to gather into the drop net during catching, the escape rate is reduced, and the technical effect of further improving the fish retaining rate is achieved.
