You can catch it up there coddy mate, but I'd just take some with you. The tackle shops up there all sell frozen and obviuosly you can get fresh from the supermarkets.
If your gonna fish the shore the following day then you can't go far wrong if you fish the old church mark. With the church behind you fish to the right hand side,,,,there's a cracking hole there that holds thornies and spurs ;0)
A friend of mine was up a week or so ago and got one or two spurs but said it should fish much better as the summer kicks in...
Cheers
