Here in n/w Pa. we have very liberal limits on panfish. On my home lake we can keep 50 panfish, any combination. A lot of my friends will and do keep 8" crappies. This lake is full of nice panfish so it doesn't hurt the population of them. Some days i will keep a few 9.5" crappies but thats as small as i go. If i cant find the bigger fish, i dont take many home. 10 of those 9"ers will give up some nice fillets. If i have them in the livewell and i start catching the 10ers, i throw the 9ers back.
