I don't think we have to agree to disagree at all.
I can only speak to my local situation. I am one of the founding directores of our local club and in our constitution we have a "sportsman" clause. Part of that clause deals with the treatment of live fish even if you are fishing outside of a tournament. When you join our club you have to agree to this. If you are caught mistreating any fish,in any way, you're membership can be revoked and you may even be reported to the authorities depending on what you've done.
We have a lot of lakes locally and out tournaments are set up with great care so that there is minimal effect on the resourse. We work closely with DNR on this and they have done extensive testing on the resource.
Basically what I'm saying is that it is up to each member of each club to do their best to "protect" the resource, not to exploit it. We have heard the stories(all the way up here) about lakes being virtually wiped out by the high profile trails. This, I agree is just wrong and I don't understand your local DNR putting up with it. We have to apply for permits for each tournament and if DNR feels that a certain lake has seen too much pressure they will pull the permit.
As far as the inventive angle goes there have been many inventions done under the pressure of "competition". Medical as well as mechanical. This type of competition is no different.
Don't get me wrong here; I'm not upset with your posts; I'm just stating my opinions and thoughts on the matter. I'm a great believer in you get what you create.
