Yesterday I caught & filleted a bunch of bluegills and when I was down to the last 2 or 3 fish I noticed what looked like fat deposits in the fillet I was doing. I cut one of these spots out with the tip of the knife and when I put it on the bench it moved, looked like some kind of worm. Didn't keep that fish but brought the rest home and gave them a very good eyeballing. Many of them had one or two of these spots embedded in the flesh so we threw the entire batch out.
A Google search for bluegill parasites turned up this Q & A session from the Pennsylvania Fish Commission.

Anyone else ever see these parasites?
