After listening to the video from the 20th. This is about the Forks guides association drumming this up to keep guides from afar off the West end rivers. Its ok for them to catch and release the same fish day in and day out but not Joe from the other side of the mountain.
If a fish has a 5% mort rate when c and r'd. What if its caught 10 times? I garentee the same fish get caught over and over.
