There are about 2 000 fishing areas, also known as FVO, in Sweden. Most have been formed since 1981, when a new law was adapted to fisheries management. This form of managment has been very succesfull in lakes and streams. The fishing area is managed by a Fishery Conservation Association. The area is the geographical unit. The association consists of all owners of fishing in the area. The fishing grounds are rural and agricultural properties of a third resource, the forest and cultivated land.
