The best thing I ever done unintentionally to prevent unwanted fishing was to start Hosting the Disadvantaged / Handicap fishing event. Things changed after the word got out what was happening there.
It appears most People do not want to be labeled as TAKING or STEALING from HANDICAP CHILDREN. I no longer find the magical floating corks and unknown foot prints on a regular basis. Friends are no longer harassing me about fishing and taking fish as they know the fish go towards a good cause. The few people that do fish are generally very respectful and will only take enough for a meal.
By no means does it end every problem though, New problems present themselves in other ways. For example had a dad that brought a disabled child and I arrived to find him fishing and the child in the vehicle.
