Found on hill top - presumed prey remains from White-tailed Eagle.
No interactions present.
I'd go with pollachius pollachius on this one based on the significantly longer lower jaw. That and the colouration.
Many thanks Cathal
You were spot on with the common name. Its a very distinctive mouth on a pollack, quite different from that of a coley(P. virens).
