Where are the perch???

So went out on the ice today with a nice spread of small to large bait. got lots of larrys, a couple smallies, and a ton of pickerel but no perch, which was odd. Then I realized i haven't nabbed a perch in weeks, even with multiple trips. Anyone know why this might be? I was thinking they could have already spawned so now they aren't eating?? Thanks!

Btw, for anyone interested, Flint pond still has good ice but getting broke up at the boat ramp by guys on snowmobiles so you have to jump!
