Why do you have to reduce the GSF population?
Although they don't get as large as a BG or CNBG, they will outfight them every time. It's OK to try to cull them but I doubt that you can really make a difference.
BTW, this weekend, if I can get a friend to help, I will seine my forage pond. I will toss the BG, RES and GSF all into the same pond. I really don't have a problem with them. The BG will out spawn them every time and, over time, the GSF will be gone. With their limited fecundity they can't hold up to predation or competition for food.
