I was on a website that strongly discouraged the use of grass carp. According to them, experience has shown that GC reduce BG numbers and hence LMB growth. They cited an old 1978 study to support this thesis, https://afspubs.onlinelibrary.wiley.com/doi/abs/10.1577/1548-8659%281978%29107%3C172%3AEOGCAC%3E2.0.CO%3B2


Comments? I guess I can see that if GC wipe out weeds entirely, this would be very bad on a number of levels. And it does make me nervous to think of them hogging the fish feed. But are more limited numbers that just reduce weeds somewhat really such a bad thing?
