Strange fuzzy halos

[FlutterChin]

I don't have koi but I do have some large gold fish. I noticed this year that some of them have developed strange "fuzzy" white areas on their bodies. Almost like a stuffed animal loosing its stuffing. Are these injuries? or some sort of fungal growths? If its a parasite what can I do to get rid of it?
Thanks

Flutter I have no idea how we missed this post!!!! Sorry about that.

Fungus or Sap perhaps, better diagnosis with a picture.
