The Nissan runs from the Småland highlands to the Kattegat at Halmstad — a compact granite-gneiss river with a responsive spate character that puts fish on the move within hours of rain. Atlantic salmon run from late June; sea trout are present through summer. The water fishes well at medium height on the drop after a lift, with salmon holding in the deeper pool heads and sea trout distributed through the runs. Less celebrated than the great northern Swedish rivers, which in practice means fewer rods on the water and more time in the pools. Atlantic salmon are managed under national rules (Havs- och vattenmyndigheten) — quotas, size limits and catch-and-release apply and differ between Baltic and west-coast rivers; check current rules before fishing.
