Problems solved by technology

[0002] Traditional fishing in rivers, lakes and seas mainly adopts artificial net fishing. This traditional fishing method has many shortcomings: 1. It consumes too much labor and is inefficient, resulting in high cost; 2. Fishing nets are easy to use. Destroyed by obstacles, the reuse rate is too low. As the price rises, nets become more and more expensive, which ...

Abstract

A device for catching fish by water flow comprises a working platform. A submerged pump is mounted on the working platform, a water outlet of the submerged pump is connected with a hose, the other end of the hose is connected with a trident pipe after being subjected to gradient diameter-expansion treatment, the other two ends of the trident pipe are connected with a flared water outlet and a fish collecting box respectively, and a porous rectifier is arranged at the joint of the trident pipe and the hose. The device for catching the fish by the water flow has the advantages that the device is designed according to rheotropism of the fish and generates fond flow velocity adapting to physiological living habits of the fish to lure the fish to enter the fish collecting box, so that fish luring and trapping effects are good, and reuse rate is high; the device can be used for the fishing industry and is capable of remarkably reducing fishing strength, energy consumption, improving fishing efficiency and causing no damage to the caught fish, low in requirements on target water area environment conditions and high in stability and safety.

Description

technical field [0001] The invention belongs to the technical field of fish luring, and in particular relates to a device for luring fish by using a submersible pump to generate water flow. Background technique [0002] Traditional fishing in rivers, lakes and seas mainly adopts artificial net fishing. This traditional fishing method has many shortcomings: 1. It consumes too much labor and is inefficient, resulting in high cost; 2. Fishing nets are easy to use. Destroyed by obstacles, the reuse rate is too low. As the price rises, nets become more and more expensive, which also leads to high costs; 3. For waters with ecological and environmental protection requirements, it is easy to disturb the ecological environment of the waters; 4. This kind of fishing The method is easy to cause the death of fish caught ashore; 5. The traditional fishing method is easily affected by weather changes, and it cannot be operated in strong wind and heavy rain. Contents of the invention ...
