Kainuu Fisheries Research Station (KFRS) infrastructure

In Kainuu Fisheries Research Station (KFRS) in Paltamo, a wide range of cutting-edge research is carried out to promote the conservation, diversity, management and sustainable use of fish stocks and river ecosystems through extensive national and international cooperation. The research is carried out on research platforms simulating aquatic nature, combined with modern observation and monitoring equipment. In addition, production-scale fish farming research can be carried out. There is no comparable infrastructure anywhere else in Europe.  Kainuu Fisheries Research Station in Paltamo is part of the European AnaEE research infrastructure.

In Paltamo, a wide range of cutting-edge research is carried out to promote the conservation, diversity, management and sustainable use of fish stocks and river ecosystems through extensive national and international cooperation. The research is carried out on research platforms simulating aquatic nature, combined with modern observation and monitoring equipment. In addition, production-scale fish farming research can be carried out in Paltamo. There is no comparable infrastructure anywhere else in Europe. Kainuu Fisheries Research Station platform in Paltamo is part of the European AnaEE research infrastructure. 

Paltamo is partly stocked with, or can be stocked with, farmed fish species of different ages needed for studies. If necessary, wild fish caught in the wild can also be brought in for research purposes. The property will house the indoor and outdoor research facilities, offices and technical support facilities, research process water and residential wastewater treatment units, and accommodation for visiting researchers. Fish habitat adaptation will be studied on a stream research platform where biodiversity and stocking studies can be carried out. 

There are several hundred different types and sizes of test units available, both indoors and outdoors. The water for the experimental units is taken from nearby Lake Kivesjärvi, but spring water is also available for studies. The water can also be heated or cooled if necessary. The indoor experimental rooms are equipped with artificial lighting that follows the natural light rhythm, the intensity and rhythm of which can be adjusted to suit the needs of the study. The study also has access to a pond of about 7 hectares, which can be drained if necessary. The pond can also be used for fish farming as a natural feeding pond. 

According to the existing environmental permit decision, the plant is allowed to use water at a monthly average rate of 0.63-0.75 m3/s. According to the Finnish Food Safety Authority's fish disease monitoring, Paltamo is a P1 plant. 

Kainuu Fisheries Research Station (KFRS) infrastructure is a part of the EU-funded Research Infrastructure project 'AquaServ - Research services for sustainable aquaculture, fisheries and blue economy', through which Luke's infrastructure is available for international researchers and developers.

Riffle-pool ponds and outdoor flumes

Riffle-pool ponds offer a wide range of opportunities for controlled studies in a natural habitat for stream fish. They are basically concrete units where the flow and the bottom structure can be controlled, for example by means of different types of protection such as natural stone and other materials. Fish in the ponds are provided with natural food, such as insects, from the ponds or from the inflowing water. The equipment also includes the possibility of monitoring fish behaviour using cloud-based RFID (PIT telemetry) and video monitoring.
