The construction of Finland’s most modern trap and transport facilities for migrating fish was started in Montta at the beginning of May.
The work has now advanced to the setting of the cornerstone. A cornerstone setting event was held at the construction site adjacent to the Montta power plant on 31 May 2016.
The cornerstone was set by representatives from Fortum, the Muhos, Utajärvi and Vaala municipalities, and the North Ostrobothnia ELY Centre, who are jointly responsible for the funding of the project, as well as representatives from Kreate Oy, which is responsible for construction of the facilities.
Fortum, regional municipalities and the North Ostrobothnia ELY Centre decided to build the fish trap and transfer facilities in conjunction with the Montta hydropower plant because of the challenging environmental conditions for revitalising migrating fish populations in the River Oulujoki. The river is fully harnessed and produces the regulating power necessary for society’s energy supply.
In the trap and transport process, the fish migrating upstream swim into the trap and are guided (human touch-free) into a transport tanker truck. The truck transports the fish, now in good, rested condition, past several power plants to tributaries where breeding grounds have been restored.
“The Montta trap and transport facilities will give us experience with what can be done in highly constructed waterways using the new type of trap and transport process,” says Timo Yrjänä, Head of Water Resources Unit, North Ostrobothnia ELY Centre.
The trap and transport facilities at Montta is one of the Government’s spearhead funding projects. The trap and transport facilities together with the modernised fish farm facility make the Montta region an excellent target for studying the management of migrating fish populations in constructed rivers and for revitalising the migrating fish populations in the River Oulujoki. When needed, brood fish and roe for the fish farm can be sourced from the salmon swimming into the trap and transport facilities. This will further improve the quality of the obligatory stocking of fish in the Oulujoki water system. The trap and transport facilities will also support the studying of migrating fish behaviour. The information gained from the use of the trap and transport facilities can be applied in the planning of migrating fish projects in constructed water systems.
