Seeing lots of dead sunfish all within the same size class on a daily basis. I'm noticing about 3-10 new dead fish daily around the outside of the pond. I have all size classes of sunfish from fry, 1", 2, 3 and up to maybe 8/9" but only seeing that ~3" class floating around the edge.
Water has been down a little and its been warm but get plenty of wind across the pond for aeration.
I did see one sunfish in the shallow barely swimming and upon closer inspection it was missing an eye so I tossed it out. By the time I see these dead fish the eyes are usually missing but sometimes not.
When I see dead minnows with eyes missing, to me that means that the fish that are alive are hungry - pecking at the corpse, the softest part are the eyes.
