"I have NOT found this particular parasite anywhere else and I have fished and closely inspected fish from numerous places"
I agree totally. After you reported this for the first time last year, I have been looking for these as well and have found none elsewhere. Additionally, as I stated before, I have filleted a lot of Rock Cliffs perch the past 2 yrs. and haven't found any there either. (I fish Rock Cliffs a lot, but rarely Hailstone) Since there are an abundance of aquatic birds in all of our lakes and they obviously are very mobile, I can't help but think that the cause of the apparent high infestation in the Hailstone area might be a factor affecting the first intermediate host (snails) such as water temperature, certain type of mud bottom, or some other factor that causes the snails to do well or to get eaten heavily by the perch. I do know what you mean about the sqeamishness when you see one of these heavily infested fillets. Oh well, it has been fun to help work this up.
Moby Dick, the "grubs" are light tan colored, round to oval and are deeply embedded into the meat. The fish externally look fine. There were about 50-60 cysts in the fillet I submitted to the pathologists.
