Try contacting Amato publishing (the publisher of STS). They have published several articles relating to DNA testing of fish and may be able to point you in the right direction. Good luck.

On a side note, I must say I disagree with what I presume to be your ultimate goal of de-listing the "wild" fish you speak of. I personnaly believe even if they are inbred they still carry the genetic make-up, at least in part, of they're native ancestors. Given the proper protection and time, those superior genes will resurface.
