Don't misinterpret what he means. We've had some pretty heated arguments in the past over this type of thing. Now he buys me beer at smallmouth seminars. LOL. He's a good dude and I definitely agree with what he said. He only means well.
I don't gig as much as I used to, but I just can't stand to ban something because of a few idiots. When I do take new folks, I make sure they have somebody experienced besides them. Another big thing to keep them from sticking illegal fish is to keep them in water that more than likely will not hold any game fish. Areas with current and not much cover are perfect. Suckers still like these areas, but your bass and other fish will most likely be in deeper water with cover. About the only game fish we may come across are a walleye or a catfish and those SHOULD be very obvious. Accidents are going to happen from time to time, but it's been a rare occurrence in the past several years when I've been gigging with folks.
I just wish the punishments were WAY more severe for people that purposely go out and poach fish and game. When all you lose is a couple hundred bucks and then you can get right back in the saddle and do it again, that's no much of a reason to worry about getting caught. A few hundred bucks is nothing to most folks. Make the punishment severe enough that people actually think twice before doing illegal activities.
