I am considering putting a small number of koi in my 1.3 acre pond. Since my visibility gets up to 10+ feet, i think it would be fun to have a few high visibility pets. At the moment my pond has about 330 RBT in the 13-15" range. If the trout don't make it through the summer, I plan to try HSB in this pond next. The pond was finished last fall and has no other fish except some minnows that already existed in the spring that fuels the pond.
My question is this: how likely is it that the trout or HSB will basically eliminate the koi yoy? My hope is I can stock larger koi and not have any meaningful survival of the offspring. Do you think it would matter if there were HSB or RBT as the primary occupant?
What do you think?
