Pond Boss Forums INTRO Questions & Observations Placing branches down for YP spawn

No ribbons here in SE Michigan, the air temperature hasn't been 50 or over but for a few days. I have only seen 2 ribbons since stocking YP a few years ago and no recruitment. My pond is like DonnoBBD, rocks all the way around (no veg.) and a Christmas tree tied to shore. I have an abundance of minnows and a few walleye. This year I'm keeping my aerator off until I think the perch are done to eliminate the silt part of the equation. I may have too many of one size class or maybe too many WE for the amount of perch.
