You're right. Sorry, I wasn't thinking of this. The fish growers do seem
to have that as another motive. I guess a snail in the gut is food, but a
cyst in the tissue is another matter, so even if the trematode could
potentially ruin the edibility of the flesh, the snail population would be
decreased or eliminated if the fish being cultured were black carp.

It's hard to be supportive of the aquaculture industry on this matter,
especially when you consider the potential devastating effects on native
mollusks should the fish escape (and they will escape). It seems funny that
the AFS Fish Culture section is seemingly pro-black carp (the author of the
article is from Mississippi State Univ), even though the AFS itself is
calling for the elimination of black carp stocks across the continent.
