Don't know nuthin' about the subject or the condition in question. I got a buddy who catches fish in an Urban area in East Memphis, more like Collierville in a private lake. Showed me photos of worms in his fish, the locals explain it to what cane just mentioned, runoff from fertilizers and lawn spray. Who knows, but worms are prevalent in Urban community lakes, doubt the two are connected, but food for thought. And BTW, I ain't eating no crappie with a large growth on their persons, or well guess fishes??
