Description

Technical Field

[0001] The invention belongs to the technical field of fishery, and in particular relates to a method for luring fish with a high fish retention rate. Background Art

[0002] Fishing with a lifting net is an efficient fishing method that combines the principle of trapping with mechanical devices or buoyancy devices. The core of the method is to attract fish by throwing bait or using lights, and then quickly catch them with a lifting net.

[0003] When fishing in large water bodies such as lakes, reservoirs, rivers, and offshore coral reefs, using a lifting net is labor-intensive. The process of lowering the net each time is often timed for several days to lure fish, luring as many surrounding fish as possible before lifting the net to catch more fish. Existing lifting net fishing relies on regularly casting bait to attract fish, but fish tend to escape the lifting net area after consuming the bait, necessitating frequent re-baiting, resulting in long fishing cycles and high costs. Natural waters (such as reservoirs and lakes) are vast and lack effective physical barriers to retain fish, leading to long fishing cycles and low catch rates. Furthermore, the movement of the net during catching scare fish, and the traditional lifting net lacks effective barriers, causing fish to escape, resulting in a low catch rate and impacting fishing effectiveness. Therefore, a method for luring fish with a high fish retention rate is proposed for improvement. Summary of the Invention

[0004] The present invention aims to provide a method for luring fish with a high fish retention rate, with the aim of efficiently catching fish in reservoirs, lakes, and coral reefs at sea while reducing the number of bait castings and the luring cycle, thereby improving fishing efficiency.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A method for luring fish with a high fish retention rate comprises the following steps: setting grass bushes in a fishing device.

[0007] In a preferred embodiment of the present invention, the grass is spliced.

[0008] In a preferred embodiment of the present invention, the fishing device adopts a lifting net.

[0009] In a preferred embodiment of the present invention, the grass includes a frame, grape vines and connecting ropes. The frame is composed of a plurality of lightweight mounting rods, and the grape vines are connected to the frame through the connecting ropes.

[0010] In a preferred embodiment of the present invention, the number of the grass clumps is two or more groups.

[0011] In a preferred embodiment of the present invention, an air pipe is provided on the top of the lifting net along the eaves of the net, and a plurality of the air pipes are provided with a plurality of ventilation holes on one side facing the lifting net.

[0012] In a preferred embodiment of the present invention, the plurality of vent holes are distributed at equal intervals.

[0013] In a preferred embodiment of the present invention, an air storage tank is provided on one side of the lifting net, an exhaust valve is provided at the air outlet of the air storage tank, the air outlet is connected to one end of the exhaust pipe, and the other end of the exhaust pipe is connected to the drain valve.

[0014] The beneficial effects of the present invention are:

[0015] 1. The fishing method designed by the present invention is that when fishing, multiple groups of grass (artificial water grass) are arranged inside the lifting net. Fish naturally like to hide in the water grass to avoid natural enemies, and fish-eating fish will also hide in the grass to ambush small fish. As long as bait is fed in time during fishing, the fish retention rate can be greatly improved. In this process, the number of fish in the lifting net can be effectively guaranteed, thereby reducing the trapping cycle. When catching, the fish are frightened, and the water grass can also provide a sense of security to the fish, reducing the escape of the fish. At the same time, an air pipe is arranged along the eaves of the lifting net at the top, and multiple ventilation holes are evenly arranged on the air pipe. When fishing, open the exhaust valve and the gas inside the gas tank is discharged through the vent, forming a bubble wall around the edge of the lifting net. The fish inside the lifting net are frightened by the bubbles and will swim towards the inside of the lifting net. The natural aquatic environment is simulated through artificial grass, which attracts fish to stay and live, prolongs the retention time of fish (such as avoiding natural enemies and hunting small fish), reduces the frequency of bait feeding, and the exhaust from the vent forms a barrier to drive the fish to gather in the net in the opposite direction when fishing, reduces the escape rate, and achieves the technical effect of catching fish that eat bait and fish that eat fish, further improving the fish retention rate.

[0016] 2. The design of this invention supports rapid deployment and retraction through the square grass design, adapting to different water depths and terrain requirements, reducing transportation and deployment costs, and achieving precise trapping of fish schools, which can effectively reduce the difficulty of fishing and improve fishing results.
