TFS are wonderful SMB forage.
I have not had any luck in introducing them or establishing them in ponds up to 3 acres with SMB--probably because they are such ideal forage that they are preferentially consumed.
Even in a new pond, with really large 4-5" TFS introduced right before spawning in the spring, a relatively small population of SMB was able to nearly eradicate them by late fall.
They might do better in a heavily fertilized pond; these had visibility of up to 5'.
Would love to hear from others who have been successful in their efforts to introduce/maintain TFS in smaller waters.
