Yes you are correct very subjective world we live in, however I'm just asking for an article where Grass Carp were a real success and helped a fishery become better, not where they saved money for homeowners who didn't want to pay for chemicals, not an article where they successfully managed the weeds, I would like an article if not numerous articles of where introduction of Grass Carp resulted in more and bigger fish being caught while maintaining a nice balance of weed growth. Most times I think what happens is certain homeowner says I want to "control" the weeds, lake manager says ok let's put some grass carp in, presto weeds are all gone every last one homeowner and lake manager look like heroes when now they have just set that lake up for massive algae blooms, stunted fish, dirtier water, did homeowner know that was he informed, I doubt it.
I'm not sure if anything would give you the conclusions you're wanting. "Not wanting to pay for chemicals"? What if a lake owner simply does not WANT to add a chemical? Chemicals have risks! Grass Carp have risks! YOUR version of success may be the same definition of total failure to another. If someone hires another to help control or manage a lake/pond, the person hired would (or should) determine as clearly as possible what that owner wants. EVERY lake and every owner are different...
If you want "larger bass growth", reducing weed cover chemically or with Grass carp will accomplish that, short term. Less plant cover means easier eating for LMB, BUT, it also means the forage fish have no place to hide and grow....so unless you spend big $$$ adding forage fish, that extra growth will be short lived and probably reversed soon. No ONE thing creates bigger fish for a sustained length of time.
