Enforcement!! Ignorance of the law is not an excuse. All the money raised via the Columbia Endorsement should be used for enforcement! The VAST majority of those killing wild fish know EXACTLY what they're doing. Stick them with a huge fine and lost licensing for a few years and the problem will go away. Serious consequences are a much better motivator than online training/education, etc. Edit: PT beat me to it. The best solution demands the highest cost to the violator.
