Fishing districts may establish a closed area for up to ten years in waters where valuable fish species live, spawn or migrate. The decision to establish a closed area determines when and how fishing is restricted in the closed area.
A decision on a closed area may also restrict the so-called general fishing rights, meaning angling, jigging and lure fishing.
Decisions on closed areas are notified on municipal notice boards and in the Official Journal. Many fishing districts also have websites which provide information on closed areas.
Rapids and currents in waters rich in salmon and whitefish
According to the Fishing Act, angling, jigging and lure fishing based on the general fishing rights are prohibited in rapids and currents in waters containing salmon and whitefish.
Under the Fishing Act, a water body is considered to contain salmon or whitefish if these fish species migrate up or along it or if it has been stocked with them in significant numbers. Salmon species also include sea trout, lake trout, river trout and rainbow trout. When necessary, the Centre for Economic Development, Transport and the Environment decides whether a water body is considered to contain salmon or whitefish.
Nature conservation areas
Fishing may also be restricted under the Nature Conservation Act. Potential fishery restrictions vary from one nature conservation area to another.
Fishery restrictions concerning nature conservation areas are written down in decisions issued by the environment centre. The decisions are only available in the archives of the issuing centre.
