FishPrince's point on "probability of getting caught" is an interesting one.

I continue to wonder how and where the best use of well trained volunteers could help the situation. I'm aware it's a complex and difficult issue, but with so many good folks out walking the rivers, why this approach isn't at least tried in a pilot program.

With just 50 volunteer "fishermen/jr. wardens" out there, odds of getting caught go way up.
