For anyone who’s been “perching” in a lake with big pike and muskie present will also find the perch are a flavorful favorite of those fish as well! In fact, I dare say, they eat more perch than the walleye! However, there is a fry relationship ratio between walleye and perch. If a lake is run over with perch, it’s usually had to get walleyes started to any great numbers. Also, a lake that has an abundant walleye presence has the same effect on perch………..the more walleye, the less perch.
