I am 60 and all the old timers I have fished with have said since I was born "Keep ever white perch you catch or they will take over".
There are slow days that I wish they would have taken over. I do release all 13-14" females in the spawn. Other than that I keep what I can eat fresh, never frozen from the lake. Keep what you choose and just have fun. BTW, a 3lb will go on my wall if I live long enough to catch one.
