Yea, I'm really scratching my head on this one. If it's BG then I have to deal with them tainting the genetics of the new ones I will be putting in. If it's GSF, then they will compete for the food sources with stocking anything new. Either one makes it a not-so-ideal situation. I was planning on letting my pond "brew" for a whole year, building up the forage base. Now, I feel I have to act quickly with a stocking plan to quell this uprising.

I don't want to consider a kill off. Mainly beacuase of cost, but I also would find it hard to do personally. Any ballpark ideas of cost for a 1.25 acre pond 10' deep? I imagine it would have to be handled by professionals.

Thanks for the help so far, ..........Jim
