Project summary

Edit project overview to modify the project summary.

Construction of the fishway in the Merikoski brook was the first step restoring the Oulujoki river for migrating fish. Merikoski water power plant was the lowest obstacle for fish migration before the fishway was constructed in 2003. The constructed fishway now enables salmon and other migtating fish to rise up 40 km to the lower reaches of the Oulujoki river. Migratory fishes are planted into the Merikoski into the upper and lower parts of the rapid every year. Also the fish migration, the amount and types of the fishes are monitored with the help of underwater videocamera and fish counter.
