I have found a couple of lakes that have some big blue gill and redear in them. I was wondering how old and how long in length do this fish have to be before they are grown and spawn? I love eating them but I also want to protect them from over harvesting. Seems like 7-10 inch fish are what most people are keeping. I fish for catfish a lot and I know the age that they spawn and I try to use that info when I harvest them to eat. Thanks for any info
