Buddy:
You raise two interesting points; limiting ourselves to a reasonable number of fish a day and actively participating in reporting violators. I'm a Leave No Trace educator and at one extreme LNT may be interpreted to discourage all hunting and fishing. However,since it is a program of principals and not rules, a reasonable accommodation would be to limit ourselves to a set number of fish (suitable to species and environment) regardless if we catch and release or not. In this case we would stop fishing when we have caught what we might think a creel limit would be. I think this would be an ethical solution and I am going to practice it in the future and suggest it in my presentations.

We have a TIP (Turn In a Poacher) program here in Indiana. I'm sure it is in other states and countries too. To me, it is a responsibility to turn in a poacher. It is unethical to not turn in a poacher.

Thanks for the suggestion.
