Lake Oulujärvi is the central lake of the Oulujoki waterway and the fifth largest lake in Finland. It is also known as the 'Sea of Kainuu'. You can easily experience the maritime atmosphere at Ärjänselkä and Niskanselkä, which are Finland's largest contiguous inland water areas. The state-owned water areas (nearly 40,000 hectares) are located in these open waters. In addition, the Oulujärvi permit area includes smaller water areas in the surrounding region.
All fish species typical to the area are present and reproduce within the permit area. The lake has strong populations of perch, pike, pike-perh, and vendace.
1 January–31 December
Maximum catch during 24 hours in Lake Oulujärvi: a single boating party can catch a maximum of five (5) pike-perch.
Trout with an adipose fin is completely protected.
The need for an angling permit depends on the type of waterbody and how many rods and lures you will use.
In this permit area, you will need an angling permit when lure fishing in sections with rapids and running water. You will also be required to pay the fisheries management fee, unless you are under 18 years of age, over 70 years of age, or are 65 years of age or older as of 31 December 2023.
If you are lure fishing with only one rod and lure in still waters, such as on lakes and in river pools, payment of the fisheries management fee is sufficient. You will also require an angling permit when fishing with multiple rods or lures.
Hook and line fishing and ice fishing are fully prohibited in rapids and running sections of waters with migratory fish stocks. You can refer to Kalastusrajoitus.fi (Fishing Restriction Service) to check waters with migratory fish stocks. In still waters, hook and line fishing and ice fishing are permitted free of charge with one rod. If you are hook and line fishing or ice fishing with more than one rod, you are required to purchase an angling permit and pay the fisheries management fee.

Lake Oulujärvi is regulated to meet the needs of hydropower production. The water level in the lake therefore varies according to the season, which is important to keep in mind when moving on the lake.
The power company stocks whitefish, trout, and pike-perch to compensate for the disadvantages caused by the regulation of the watercourse.
