How do you build a cat fish stunner?  iceng3 years ago I do not
believe it is possible to only stun cat fish and leave other
kinds of fish unaffected !  sbushard iceng2 years ago It is very
possible. It works off the size of the fish. Since Catfish are
generally larger and bottom dwellers, the drag line stay on the
bottom and since to Voltage is low, the small fish aren't
effected by the small amount of current due to their size, the
larger catfish however absorb more current, stunning them
temporarily bringing them to the surface, how ever, since this
is a pulse of the current, you must be fairly quick as the
effect wears off rather quickly. It is the Dept. of Natural
resource in nearly every state's go-to method for checking fish
population on a yearly basis. However their device turns up the
voltage to stun all fish so they can account for large and small
alike. It is no more cruel than catch and release, which is fine
with me since I catch and eat. The fish in some of our mountain
stream in NC don't even
