For Crappies and Bluegills there isn't a bag limit...I am not sure how the Wild-life biologists monitor the ponds and how often, but the majority of them are very good fishing....for panfish, not many people fish for them here why.... I don't know...they just ain't right, in my opinion...they don't know what they are missing which is good for me, they are big into trout, salmon, stripers, bass...
