Electrofishing uses direct current electricity flowing between a submerged hode and anode.This affects the movement of the fish so that they swim toward the anode, where they can be caught. Electrofishing is a common scientific survey method used to sample fish populations to determine abundance, density, and species composition.

Well I came across this, electrofishing: There are three types of electrofishers: backpack models, tote barge models, and boat mounted models, sometimes called a stunboat. Backpack electrofisher generators are either battery or gas powered. They employ a transformer to pulse the current before it is delivered into the water.
Conveniently, this small innovative boat can be disassembled, carried to remote loions, and easily reassembled by the stream or pond. Within its lightweight frame, it features an industry leading SmithRoot electrofisher and booms. Adding to its diverse capabilities, it can even be operated using handheld electrode poles similar to a backpack.
Galvanotaxis is uncontrolled muscular convulsion that results in the fish swimming toward the anode. At least two people are required for an effective electrofishing crew: one to operate the anode, and the other to ch the stunned fish with a dip net. Backpack electrofisher
