ewest - where was the location of that study?
This year in NW OH the spring warming temps after ice out have been earlier than usual. Air temp was 80 today Apr 1, a record. Ice out was Mar 11 and first YP eggs were laid eight days later Mar 19 - water temp 50F. Usually first eggs are similar to that mentioned my ewest above Mar 27-Apr 1. I do have a few YP that are exceptions and spawn several days earlier than the main group. Yesterday Mar 31, I removed 5 gallons of YP eggs. Another pondowner 45 mi directly west of me also removed 5 gallons of eggs earlier this week. I expect the main spawn in my pond to occur this week. My records show normally the main spawn for YP in my pond is Apri 2-10. When I hear the toads trilling, my YP spawn is basically done.
No aquashade in my pond. I have found blue dye in other ponds slows the water temp warming, esp deeper, and delays the spawn several days to a week or more which is not necessarily a bad thing.
