I'm very curious to find out what caused the wounds. I have caught 3 or 4 sunfish with these same bumpy/oozy marks. Some came from creeks, but at least one came from a hole in the ground (pond) no bigger than two hot tubs. The lamprey theory, while possibly true for the pictured fish, doesn't hold for my catch.

By the way, the pictures are nice for showing the details. Good job to both of you.
