You guys don't know jack. Making up more rules and regulations which aren't being called for.
I am so glad that some of you people are not involved with the decision making of our fishing regulations.
You wouldn't know flossing if I ran my leader b/w your legs and hook your jewels, head first.
If you are so much concerned with ethics, then just quite the fishing. Don't you know that these fish are in the river to spawn? Why are you harassing them during this critical stage of their lives? You say they bite out of aggression.
I say leave them alone. Let them do their own aggression among themselves as nature intended them to do. Stop stressing them out by tossing spoons, spinners, jigs, or whatever at them. Its just unethical and unnatural for us to interfere with their spawning process don't you think. There, take this ethic and stick it up your ethical reservior.

Shoot, I've seen guys flossing fish in 4ft of water using egg clusters. They don't know it, but I was on opposite side of them actually seeing the fish mouthed the leader first.

It all boils down to who is catching more fish doen't it.
A fisherman catching more fish than you, he is landing fish after fish in the mouth while you're trying your very best to read the water and attempting to harrass teh fish to be aggressive. This guy is not breaking any laws. Hell, he releases all of his catch. You are doing everything RIGHT, loosing gear every cast, switching lure every 5 minutes, and can't get a head shake. What is this guy doing wrong? Now your true feelings come out, jealousy and all. Its got to be THE ETHICAL FISHERMAN CODE that he is breaking. He is breaking YOUR LAW, "HE IS CATCHING MORE FISH THAN YOU."
The gammies can't help you. If you had your way and no body is looking, you send this guy floating down river face down.

Do what you got to do, but please stop trying to protect me from myself. Sick and tired of the homo, liberal, do gooders pushing uncalled for ethics to the world.
