Just curious. When salmon return to our east-coast rivers do they take different routes? For instance, do fish returning to the Tay come round the top of Scotland and turn south or thru the English Channel then head north. I take it that the buy-out of nets off the Northumberland coast means that Tweed fish would be taking the latter route. I would guess that Spey.Dee.Deveron. Findhorn etc..would be coming round the north coast. As I said, just curious.
Cheers

I think all the east coast fish come around the top of Scotland. I imagine that if the Tweed run went up the English channel there would be a netting station at Dover! The reason Tweed fish ended up in Northumberland nets was that some overshoot the Tweed and then head back up north along the coast. I don't know where I've got this idea from, maybe someone can confirm.
A similar sort of thing is said to happen on the South Devon rivers. The fish enter Lyme Bay and then go around anti clockwise picking up their home rivers as they head back west along the coast, although how anyone knows this is beyond me.

Ian,
I would imagine that they would take different routes. I'm not sure that the removal of drift / coastal nets would change this, maybe after they have been back and forth a few times to sea.
How they navigate back to their home river is truly amazing when you think of all of the obstacles they have to avoid. Nets, Predators, Contamination / Pollution, Speyducers Flees, Gooies Pink Tomics.

I don;t know about other east coast rivers, but I am reliably informed that fish destined for the Tyne and Tweed travel down the north sea as far as Whitby, then turn towards the coast and then proceed back up north hanging off about six miles out till they get off thier home river. I might be completely wrong, but this was the way it was explained to me.

Yes tweedgillie that is what I have heard also, it is around about Whitby and Flamborough Head that the incoming tide from the English CHannel and the Pentland Firth meet in the North Sea. Might have something to do with it. tweedsider

It's quite fascinating this. I take it that ALL Atlantic salmon, whether originating in Russia, Norway, UK, Ireland or wherever migrate to the same area, (off Greenland somewhere...Is that correct??)Do they head off there at the same time of the year or is it substantially different for each individual area??

Iain,
I think we would need to ask some of the scientist boys who may have put GPS trackers on hatchery fish to see where, when and how they manage this.
