Would that be bad? it seems that all of us with ponds under 1 acre are trying to control numbers of both predator and forage at one time or another so a self limiting factor like ovarian parasites might just be the ticket?

I can't stop NBG or LMB because it is nearly impossible to keep the balance in a small pond like mine.

I have to remove YP eggs to keep things in balance which so far has been easy to do and helpful for the waters where the eggs end up being donated to.

I don't have GSF but I imagine it would be a bonus for those who wish they didn't have them.

I guess if you stocked a few SMB you would want some recruitment there.

I'm starting to get huge numbers of GSH so a little ovarian parasite would help me get them back in check.

Not sure I ever able to identify GSH eggs in order to do a positive ID on what color they were.
