Abstract

The invention discloses an environment-friendly freshwater fish catching method, which is based on a fishing device. The fishing device is provided with a expansion device with resistance measurement;the resistance measurement of the device has two fixing electrodes, the standard value is preferably larger than that of water and smaller than that of the freshwater fish, when the resistance between the two electrodes is measured to be at the standard value, the expansion device expands; the expansion device comprises a first electrode (DJ1), a second electrode DJ2), a heater (R4), an air nozzle (QZ), a compressed air tank (QG), an inner pipe (NG) and a circuit board (DLB). The fish cultivation system adopts the environment-friendly freshwater fish catching method to continuously catch thecultivated fish. The device of the invention is easy to operate, less in manpower investment, has no accidental injury to fry, and is suitable for continuous batch fishing. The method and the system provide a new idea.

Description

technical field [0001] The invention relates to the field of fishery, in particular to an environment-friendly device for catching freshwater fish and a fish breeding system. Background technique [0002] Existing fishing techniques include nets, fishing, electricity, etc. Among them, net fishing requires a relatively large manpower investment and requires multiple people to operate. The fishing efficiency is very low and fishing is very slow. Electric fish is not environmentally friendly and will electrocute small fry. There is a technology that requires less manpower, can fish efficiently, and only catches big fish and not small fish, which is conducive to reducing manpower and improving efficiency. Contents of the invention [0003] In order to overcome the above problems, the present invention designs an environment-friendly freshwater fish catching device and a fish breeding system. [0004] Technical content 1. An environmentally friendly device for catching freshwa...
