Minor quibble, it was geese, not ducks, as I remember.  More to the point, I
don't think that anyone has demonstrated imprinting behavior in fish.  The
theory that a fish raised away from its' parents cannot properly raise its'
own offspring has been in the hobby for a long time, and probably originated
with Angel or Discus breeders.
My own feeling is that the ability of a pair to successfully raise its young
has more to do with conditions present at time of spawning than anything else.
Listening to others one the list relate their experiences tends to corroborate
that viewpoint.
Persuasive arguments can be made for other viewpoints, as well.  I guess until
someone does some good experiments and settles it once and for all you pays
your money and takes your chance.
