Hello.
I don't know if I am afraid for nothing, but in my main pond friends and family was fishing, so one day I was afraid, if they catch to much or all the females or all the males.
So I made a little pond 50x100 feet and I put Yellow perch in it.
Now everybody can catch all they want in the main pond.
I want to put Smallmouth bass in the main pond, I thing I will have to do the same thing, make a little pond for the smalmouth genitor.
Like I said perhaps I am afraid for nothing

A+
