I caught this bluegill earlier in the week, took a photo of it because it was more colorful than most I catch (though it only shows a little in the photo). When I got around to looking at the photo on my computer I noticed a couple of white spherical lumps under the gills and a couple on the bottom of the head that I somehow didn't notice when I caught the fish. Has anyone seen anything like this before? I presume it's some kind of disease but I'm not familiar with it.
