I think maybe I caught a 4 lber a few back when I first started crappie fishin... I just didn't have something to weight it , but I did measure it being some 18" long. Of all places I woukdnt had thought of catching such huge fish too,,,, It was at sheby farms,,,The year I caught it , it was loaded with hybred strikers and tons of shad,,,,l ever since that one year! all I have caught are dinks,,,,I think they shocked the lake that year and and rid themselves of all the hybreds stripers and big crappie,,,,,can't figure how that changed everything , but it did,,,,
