Problems solved by technology

It is not possible to catch bearded catfish exclusively. It is inefficient to use a cast net to fish in a wider water surface. It is labor-intensive to use a pull net to fish, and it is very inconvenient to catch fish. When using a cast net or a pull net, the fish caught are easy Injured or missed catches, ...

Abstract

The invention discloses a sound generator for trapping Clarias fuscus. The sound generator for trapping Clarias fuscus comprises a transformer, a capacitor and triodes; the output end of an oscillation coil of the transformer is connected with the capacitor in series; the centre tab of a control coil of the transformer is connected with a power cathode and the emitter of the triode through resistors; the other two ends of the control coil are connected with the bases of the triodes through diodes; the centre tab of a power coil of the transformer is connected with a power anode through a shunt resistor and a switch of an amperemeter; one end of the power coil is connected with the collector of a triode, and the other end of the power coil is connected with the collector of another triode and then grounded; a power input end is connected with a voltmeter in parallel; the shunt resistor is connected with the amperemeter in parallel. The fishing device has the advantages of simple structure, small volume and convenient use, and the oscillation wave of the fishing device resonates with the sleep frequency of the Clarias fuscus so as to capture the sleeping Clarias fuscus.

Description

technical field [0001] The invention relates to a sound wave fishing device, in particular to a sound wave generator for trapping bearded catfish. The invention belongs to the technical field of acoustic vibration sensing electronics. Background technique [0002] Bearded catfish, also known as bearded silver carp, sticky fish, pond louse fish, and raw fish. The salient feature of this fish is that it has no scales all over its body, its body surface is mucus, its head is flat and its mouth is wide, and there are four beards on its upper and lower jaws. There are three types of bearded catfish, namely big mouth, big head and big belly. There are two kinds of colors: one is blue-gray, the other is yellow-toothed, and the catfish with yellow-toothed teeth has piebald spots on its body. The head of the bearded catfish is relatively broad, and there are several sensitive long tentacles around the mouth, which are a bit like the whiskers of a cat. There are many taste buds on ...
