The more I learn about proper management of a lake, the more I know that we must harvest some bass from a body of water. Selective harvest is the key. I my home lakes I keep whites, hybrids and a few LM bass. Your state DNR is banking on people keeping bass from the lake. That is how management works. As you fish your lake you will see the size that needs to be removed from your lake. This will improve the overall catch even in a small body of water that is stocked.
My home lake is inundated with 12" bass this year. Next year we will have to take some 15"s out to grow a healthy population of larger fish in future years.
Let the big ones go, based on the norm for your body of water. Mortality of hooked fish is another factor; keep them.
