Lou,
In Texas, we can only stock the Mozambique Tilapia. I have testified here to their benefits from first hand, personal experience.
I just read a magazine article about flyfishing for bass in Mexico and the professionals there attribute their fantastic bass fishing to the Tilapia...but they also say that local commercial fishing (ie gill netting) is needed to keep the Tilapia population in check, because they do not die out in winter there and they will reportedly eat small bass fry when they (Tilapia) reach a larger size. I guess that is a possible down side.
If this winter is any indication....water temperature 62 degrees...even East Texas may in the future be able to carry these fish over in the winter.
