Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish. The pulse trawl gear consists of a number of electrodes, attached to the gear in the tow direction, that emit short electric pulses.This circuit uses a 2A transformer from the old speaker. It is rewinded to create a high frequency (~ 500Hz) voltage 300V. It uses 2 mosfet IRF3205, ZVS driver. It is really simple but very effective, you can catch tilapia, carp, and catfish.
