The Iijoki migratory fish spear project revitalised Iijoki salmon and sea trout populations. In the lower part of the river, the living conditions of the pelts and pigs were also supported. The project measures were: Promoting the construction of the fish road of the Raasakka power plant dam, down migration solutions for smolts (e.g. construction and installation of a smolt control fence in Haapakoski), planting of small chicks and measures on the old tracks of Raasakka and Maalismaa.
The project was funded by the Ministry of Agriculture and Forestry, PVO-Vesivoima Oy, Ii, Oulu, Pudasjärvi, Taivalkoski, Kuusamo, Metsähallitus, the Regional Assembly of Oulu Region and the Iijoki river basin fishing area. The Northern Ostrobothnia Centre for Economic Development, Transport and the Environment and the Natural Resources Institute Finland were also strongly involved in the project.
The project was implemented as part of the Government's nature policy spearhead project.
