Rob,
Apparently Tuna are regularly seen feeding off of Orkney and the Shetlands.
Really ? I don't think so . Any Bluefin there are chance encounters mate from the fast dwindling eastern stock's oceanic wanderings. You would have a long time waiting .
These fish are known to be Atlantic ocean wanderers ,migrating from the eastern seaboard of America to the north of Shetland , even over to the Norwegian coast then sometimes down into the North sea ,crossing over to the North East English coast (following the clockwise North sea counter current) .The fish were probably attracted to herring in the drift net fishery there. This was the reason for the Scarborough fishery in 50,s. In some years the herring pair trawlers off our coast right here encounter one odd one or two but it's been a few years now that the last one was landed. I remember seeing one at Peterhead many moons ago that was over 1000 pounds , absolutely massive.
They reckon that the world's Bluefin stocks have been reduced in the past thirty years to around 5% of their former total. Something to think about .
There was a guy set up a tuna business off the West Coast of Ireland ,I don't think he survived though such was the unpredictable nature of the tuna shoals.
One on a fly rod certainly would be quite an experience Sandy !! Incidentally , do you know if the tuna in the piccies were chummed up or was it just right place right time for a blitz?
By the way ,best of luck with your 10 wt Rob !! Hmmm match wood comes to mind !
. You are talking about fish in the 600 to 1200 pounds weight class here.
Paul.
