REALLY good point, Spark. For me personally, I'd prefer managing HBG than FA. But, I don't think it necessarily has to come to that ultimatum. I have found [again in my personal situation] that high density population of apex predators allowed to grow to sufficient size/gape will eventually get on top of the BG and manage the population, despite the abundant cover my rooted vegetation provides. I have no other structure/cover in the pond, so in the Winter while vegetation dies back it's literally a bathtub from November to April. I suspect a very significant number of YOY BG and YP get hammered during this spell with no refuge. Now, consider that HBG are far less fecund than BG, and 97% offspring are male, I think Wann is facing a far more manageable situation than someone like myself, Banks, or Yolk who manage cool water species fisheries with BG present. If Wann can assist management efforts with some angling and trapping, my guess is he can keep on top of the HBG.
