I was at Stinky Corner this evening watching a number of very substantial fish swirling in the shallows as the tide came rushing into the pools next to the road. They were large - I would estimate 18 inches to two feet long, and looked dark on top, and reddish orange below. The concave nature of the tails would suggest salmon, as would the level of activity in broad daylight - sea trout are mainly nocturnal. Fresh-run salmon are silver however - but the colouration I saw may well have been the colour of the bottom reflected on their bodies.
They made an impressive sight - with their dorsal fins regularly breaking the surface as they made big splashy 'rises' and surging up and down creating big bow waves as they went.
