My opinion is that many of those warnings were overblown. Just as Barry
has pointed out that blackworms are host to no known fish pathogens, I
have never traced any disease to use of wild-caught Daphnia.
Feeding richer live foods (wild Daphnia, as opposed to yeast-fed) will
foul the water more quickly as the richer nutrients make for more
ammonium and other nitrogenous wastes. That allows opportunistic
diseases a chance to invade. Post hoc, ergo propter hoc...
You won't collect many Daphnia in water containing any substantial fish
population, IMHO. [The main (rare) exceptions are where differential
reproduction rates allow a Daphnia "bloom" that the fish eventually

I had the vague feeling that my artificially-fed Daphnia were a crunchy
laxative for my fish, but didn't seem to add much rapid growth. YMMV.
