Anglers know that there’s a reason it’s called fishing and not catching. Often times the fish can sense something is amiss and will avoid taking the bait. In this video something goes wrong with an underwater carp setup, see if you can decipher what happened.
Did you see how that carp spit out the bait? It looked like it had swallowed the bait whole, but somehow it was able to get it out of its mouth. Perhaps the fish could feel the tug of the line once it had the bait in its mouth, but who knows.
Nine times out of ten this hook would have set properly, and this might have been a fluke. Either way the lesson here is that if you don’t succeed try and try again especially when it comes to fishing.
