There are several brands out there, and they all work on the same principle.
A continuous high voltage pulse is delivered to the water , and anything,
including frogs and fish gets stunned. Unfortunately, this often
eventually kills the fish,a fact not advertised in the sales brochures,
altho enough research has been done to show the effects.

The units are large, and carried on a large back-pack, battery powered or
small gas engines.And in each hand, the operator carries a long pole with a
paddle on the submerged end, and slowly walks thru the water,stunning all
life between the paddles. Largest fish are effected most.

At least one manufacturer claims to use a complicated pulse shape that
doesn't permanently injure the fish, but one thing is certain; this is
illegal except for research, and it isn't fun watching the results.

The old way was to remove the dynamo from an old crank-type telephone.
You can find them in antique and junk shops. The way we did it was to
connect the ground wire to our (aluminum) boat. Then we attached a
long, heavy insulated wire to the other terminal. At the far end of
the wire we attached about six feet of metal chain. We would boat out
onto a pond dragging the chain on the bottom behind the boat and crank
the dynamo.

Incidentally, shocking fish (or, more accurately, "taking fish by
stupefaction") is illegal here in Missouri...at least for "game" fish.
But then so is double-parking.

I understand ( from following previous posts ) that there is a method that puts
a small DC current into the water that simply attracts fish.

I suggest the poster does what I did and use google.

So is hunting with a flame-thrower...go figure.

Well, fishing with one wouldn't really work very well...

Heh heh.

My favorite fishing joke is about the kid who goes out on a lake every
day and comes back with big stringers of fish, even when no one else is
catching anything. Eventually the Game Warden takes notice. One day
the warden removes his badge, puts it in his pocket and engages the boy
in a friendly conversation. He asks if the boy minds if he goes
fishing with him the next day. The boy says, "sure".

The next day they boat out onto to the lake to a secluded cove. The
boy opens his tackle box and it is completly filled with sticks of
dynamite. He lights one, throws it into the water, it explodes, and
then he begins scooping up the dead fish and putting them on stringers.
The stunned warden then pulls the badge from his pocket and shows it
to the boy. "I'm the Game Warden. You're under arrest!", he says.

The boy calmly takes another stick of dynamite from his tackle box,
lights it, hands it to the Game Warden and says, "Are you going to
talk, or are you going to fish?"

Check "High speed pulse technology" by Frank Frungel
for a chapter on electric fishing..
