A plurality of bait placement openings are provided around the folding belts 5, and an installation ring 7 is provided on the bait placement openings. The plug cover 11 is connected to the installation ring 7 through a threaded structure.

[0052] The preferred solution of the above Pomacea canaliculata trapping device is as follows:

[0053] Sealing cover 12 design:

[0054] Working principle:

[0055] A sealing cover 12 is configured on the bait opening, and the sealing cover 12 is connected to the installation ring 7 through a threaded structure.

[0056] This design can ensure the blocking of the bait opening without the bait cage 2 installed.

[0057] The threaded structure of the sealing cover 12 makes the sealing cover 12 easy to disassemble and install.

[0058] Floating edge 8 design:

[0059] Working principle:

[0060] The top of the fishing cage 1 is provided with a floating edge 8, and the floating edge 8 adopts an air cushion structure.

[0061] The floating edge 8 can help the fishing cage 1 float in the water, ensuring that the device can stay stably on the water surface.

[0062] The inflatable cushion structure can adjust the buoyancy as needed to make the device more stable.

[0063] Anchoring system:

[0074] Summary of the working principle of this Pomacea canaliculata trapping device:

[0075] Design of the trapping area 3:

[0076] Working principle:

[0077] The trapping area 3 adopts two mesh sizes of the mesh 6, and these two mesh sizes of the mesh 6 are arranged at intervals within the trapping area 3.

[0078] The first mesh size of the mesh 6 is smaller, allowing only small fish organisms to pass through.

[0079] The second mesh size of the mesh 6 is larger, allowing Pomacea canaliculata to enter.

[0080] This design ensures that the apple snails can enter the trapping area 3, while non-target organisms such as small fish can pass freely through the two sizes of mesh openings 6, reducing the impact on non-target organisms.

[0081] Design of the capture area 4:

[0082] Working principle:

[0083] The capture area 4 uses a single mesh opening 6 size, that is, the first smaller mesh opening 6 size, allowing only small fish organisms to pass through.

[0084] The design of the capture area 4 ensures that once the apple snails enter the trapping area 3 and pass through the second larger mesh opening 6, they cannot escape through the smaller mesh opening 6 of the capture area 4.

[0085] This design ensures that the apple snails are effectively captured, while small fish can enter and exit freely.

[0086] Design of the bait cage 2:

[0087] Working principle:

[0088] The bait cage 2 is used to place the bait that attracts apple snails.

[0089] The top of the bait cage 2 is provided with a plug cover 11, and the plug cover 11 is connected to the bait cage 2 through a threaded structure.

[0090] This design enables the bait cage 2 to be conveniently opened to add or replace the bait, and also ensures that the bait will not scatter during use.

[0091] Design of the bait placement opening and the mounting ring 7:

[0092] Working principle:

[0093] Several folding belts 5 are provided on both the capture area 4 and the trapping area 3, and several bait placement openings are provided around these folding belts 5.

[0094] The bait placement opening is provided with a mounting ring 7, and the plug cover 11 is connected to the mounting ring 7 through a threaded structure.

[0095] This design enables the bait cage 2 to be conveniently installed on the bait placement opening, and the plug cover 11 can be easily connected to the mounting ring 7, facilitating the placement and replacement of the bait.

[0096] Trapping process:

[0097] Working principle:

[0098] The apple snails are attracted by the bait and enter the trapping area 3 through the second larger mesh opening 6 size.

[0099] Once entering the trapping area 3, the Pomacea canaliculata cannot escape through the size of the first smaller mesh 6 in the catching area 4.

[0100] Through this design, the Pomacea canaliculata can be effectively captured while reducing the impact on other small organisms.

[0101] Summary

[0102] This Pomacea canaliculata trapping device, through the design of different mesh 6 sizes in the trapping area 3 and the catching area 4, ensures that only the Pomacea canaliculata can be captured, and other small organisms will not be accidentally captured. The design of the bait cage 2 makes the feeding and replacement of bait convenient and fast. This design improves the efficiency and selectivity of Pomacea canaliculata trapping, reduces the impact on non-target organisms, and is applicable to the prevention and control of Pomacea canaliculata in agricultural production.
