Dave i know about how a certain species of panfish can decimate another. Our lake seems to have WAY to many small blue gill...most sem to be in the 4 inch slot. I do remember about 15 years ago the yellow bass population EXPLODED on wonder seems every cast landed a 8 inch yellow... since than never caught another!! I didn't take it personal i taught my 3 kids catch and release and they now know a picture is better than killing a good (spawner?) if you do ice fish the chain if its no bother maybe we could hook up (lol) sometime or maybe show you wonder lake im in the stage of buying ice fishing gear again.... sold all my stuff years ago?? Power auger, tent,poles and tackle for only 100$ didnt know my youngest boy would take into ice fishing shame on me!
