IBF,
I would first check with T,P,& W. They have excellent, reasonable fish biologists who if they say it's ok, then it is ok. I'm guessing they will say okay, because the Peacock will not survive Texas winters.
The Peacock does not survive at temps below 60F. Unless you have external source of heat, they probably are not for you. South Florida, Dade County, is, I believe, the only area in the U.S. that has a Peacock fishery.
If raising a predator, it does not seem very practical to re-stock every year, but folks in Texas ponds (myself included) stock rainbow trout for a very brief season, so it is not out of the question, in my opinion. If you pursue this dream, please let us know how it goes.
