The recreational fisherman keeping his/her limit every time they actually find the time to go fishing has no effect on the fishery. The guys I watch that go out EVERY day on Lake T, to their honey hole, and bring home a limit every time do.
You can not dictate ethics to someone based on YOUR perception.... based on what you see posted in their OFC threads. This may be the only trip, or one of a few for the whole season for them. So what if they keep their limit.... good for them!
Nothing gets my fur up more around here than people dictating what is "right", in their mind, to others that are within the law. And this is the opinion from someone that may keep 3 fish a year.... of course I only caught 4 !
