Abstract
An electrofishing method and apparatus employs programmable hardware to generate output waveforms that will stun or alter the behavior of fish while minimizing the harm done to the fish. By programming a variety of instructions into the programmable hardware, a wide range of different output waveforms can be produced. The programmable hardware can also monitor environmental conditions to automatically adjust and optimize the waveform parameters. Finally, the programmable hardware can be interconnected by a data network to form an array of charged electrodes, with each output related and synchronized in a predetermined way for use in electric fish barriers and guidance systems.
