The Border Esk falls under the Environment Agency's salmon rules rather than the Scottish river gradings; check the current EA byelaws and the Esk and Liddle Fisheries Association's rules. Autumn salmon run September into November, though the rod season closes 31 October. The Border Esk responds quickly to rain and fishes best on the drop after spates. Night fishing for sea trout in summer is productive; day fishing works too, making this more flexible than purely nocturnal systems. Main pool system concentrates fish — focus effort here and fish through systematically.
