I don't like frozen fish so I only keep what I'm goin to eat the next day or so if it hits the freezer I give it away to the relatives that being said if it's a slow day I keep everything over 15" if it's a good day I'll be picky and throw some back I like the cheeks on the bigger fish so ill keep a 20" plus once in awhile but mainly 15-19" hit the frying pan it's pretty much how I feel that day and if they are biting good
