I'm gonna have to say a seaforllean on that one. That fish looks to have a square tail, usually a dead give away of a brown. From what I've heard the way you can tell the difference between a seaforllean and an atlantic, is an atlantic has more of a forked tail as opposed to the browns which have a square tail. The story of that fish was posted on the Wi reports on the steelheadsite, and was caught in a Wi trib.
