FWIW, our general consensus on GSF is that they are either a manageable problem or a non-problem. Worst case with GSF would be a pond where they have been the only (or the far-and-way dominant) species for some time, and have taken up virtually all the pond's available biomass with little stunted Greenies. One can manange one's way out of even that scenario successfully (without renovating).

In your case, they have a year (at most) head start on your CNBG. The Coppernose will out reproduce them, the bass will eat them (first, probably, since they are slenderer than CNBG), and, for your own personal information, they taste just like BG. Some of our PMs here operate or strive for trophy GSF ponds, and they wouldn't consider them any kind of problem.

P.S. Check out some of the threads on GSF (looking under "Jeff has a pond" would be a good start) and that should help you decide whether or not to pursue your GSF with extreme prejudice.

P.P.S. What are your management goals for the pond?
