For your 3 small perch; 56mm/30days = 1.8mm/day and 77mm/30days = 2.5mm/day. Ice off Mar 20. If eggs were laid under the ice in 39F water (laid on March 15-20 temperature water it will take close to 12-14 days to hatch that puts it at March 27-30. When eggs hatch at around 46F, it takes at least 2-3 days for them to begin swimming. Small perch were captured April 27th - 27days. IMO it is not feasable for them to grow 2.5+mm/day in early spring temperatures to grow to 77mm by April 27. Maybe you have a super strain of yellow perch; if so fishery science should hear about it.
