Where did you get the mouth gape data for YP? I don't think their mouth size is greater than LMB at least the way I measure mouth gape. Here are some of my measurements of horizontal mouth width for yellow perch: 3"=0.27", 5"=0.59", 6"=0.70", 7"=0.86",
8"=0.94", 9.0"=1.08", 10.0"= 1.10", 11"=1.18". 12"=1.3".
