Fishing in Scotland
You do not need a licence to fish with rod and line anywhere in Scotland apart from in the Border Esk region.
You only need permission from the landowner or an angling club.
As the Border Esk flows into England you need to buy a rod fishing licence for England and Wales to fish any part of it. This includes the parts of the river and its tributaries that are in Scotland.
Fishing in Northern Ireland
You must have a rod licence and angling permit from a Northern Irish agency to fish in Northern Ireland.
