I think another way to avoid this is using live bait that is also given out as freebies. I fish off the dock with worms and crickets but also throw even more to these out with no strings attached. Maybe one out of ten crickets may have a hook in it so the fish are conditioned to think people=food. You spend a lot of time catching bait to offer as a free meal but having the fish swarm to you is worth it. I enjoy feeding as much as fishing.

Does the name Pavlov ring a bell?
