Ty -To suppliment Dave's good data, here is some perch growth information from my Yellow Perch article. Data are from only my experiences with YP in NW Ohio. Keep in mind that the males generally grow slower than the females, thus the lengths have a fairly wide spread in each group. Also these data have not be adjusted for the record breaking fast growing perch that Cecil caught this winter. The table and columns didn't align very good when they were finally posted and I had to improvise a little bit with dashes.
