Hello! I realize without any pictures or (more helpful) specimens,
this is a tough one, but I am interested in any ideas. I am
wondering if someone has any idea who/what the parasite is that
causes black cysts in small local stream fish, especially bluntnose
minnows? The black cysts occur all over the body of the fish and all
of its fins. I have looked at it under a microscope and they
certainly are embedded in the flesh, but other than looking like
cysts, I don't see any distinguishing characteristics. Dissecting
them out wasn't too illuminating either. My guess is that they are
some sort of fluke (trematode) or glochidia (clam) larvae, but I
thought glochidia only infected the gills. If it is a fluke, any
idea what genus? Thanks for any help/suggestions you can provide.
