I went out crappie fishing the other day and I noticed in the shallows there were three fish sitting there and I could not distinguish what they were. They looked like they were silverish/blueish tint almost like a fish you would see in a fish tank; like a jack dempsey. I thought someone had released fish from their fish tank into the lake. I dropped my jig down and hooked one, when I got it out of the water I noticed it was a bluegill. It was covered in white bumps all over the fish it almost looked like snail larva or lice (black bumps) except these were white? Anyone have any idea what this could have been or has anyone seen this before?
