Semantics and 5 pages of BS.
The sport of fishing with a hook and line is defined by certain rules. Fooling a fish into acting on a natural instinct (biting at food) is one of them IMHO. Once you depart from that you are no longer fishing. Im sure arguments could be made out of context to defend a different position, but who cares? Might as well call it catching or takedowning and not fishing at that point.
