Finally got around to dragging the plankton net again. Nowhere near as much plankton as I get in the late spring and summer (water temp is only about 45 degree F this time of year... increasing to a "sizzling" 56 or so in summer). I did find a fair number of these eggs
(at least I think that is what they are), but no idea what they are from. I thought Franz had posted something like this a while back but I could not find it.
Typically there were 3 or 5 eggs in each circular mass. In a profile (side view) each egg mass was shaped sort of like a derby hat (or UFO

) Each individual egg was just about 150 micron in diameter.
