Thanks for all those comments, especially Mike with the photo examples, Sandy and Hamish's comments - Hamish, I think they may have stocked with Loch Leven strain - as you know don't tend to have red spots either !
I have other less good photos of it which I will upload tonight. I am adamant it is a Brown Trout on this evidence:
1) Brown tinge's to gill plates, extensive on lower maxilla and also that butter-brown evident on belly line (just visible). The fish's back was brown in hue, not terribly clear in the photo I posted, but there are others. A typical Sea Trout (kelt) would have much less spotting, not extending below lateral line and belly would be pure white.
2) The spotting is not typical of sea going trutta - it is extensive, well marked and extends well below the lateral line.
3) As Iain alluded, it was caught on a size 14 Dry in April - not a clincher, but how many 5 lb Sea Trout Kelts are caught on the dry fly ?
4) Male fish - kype present ? Do most sea going trutta males not die after spawing ?
5) It is not a Sea Trout it is a river adapted trutta !
Yes, there can be exceptions but I am still really bealing about this. It was put he would check with "his people" and let me know ! Well thanks very much but I already know and it seems opinion on here from "my people" shows parity with my own view.
Hope Paul P gets back on this as he possibly has most experience across UK and in Scotland.

PS I still can't seem to upload photos due to a Java prob.
