I think a lot of the trout spawn throughout the summer. And part of the reason for CPR is to allow the big trout to grow even bigger, not only to produce more eggs.
Do you realize how many people catch a 5 pound trout and think it weighs 8 or 9? It's obvious by the estimated weights we see every day on these fishing forums. I would think that a ton of the fish that are weighed in were not put on a scale on the water first.
Please keep in mind I'm not trying to tear down CCA.
