New enriched rearing method developed at the station
In cooperation with Helsinki University researchers we have indicated in several experimental tests carried out at the station that simple improvements in normal hatchery tanks are essentially improving the skills of stocked fish to succeed in the nature. Read more
Enriched rearing improved survival
The migration and survival of radio tagged salmon smolts was monitored with automatic listening stations and by manual tracking using a boat along a 290 km migration route in River Tornionjoki. Enriched rearing improved the survival of hatchery fish compared to fish reared in normal tanks but wild smolts still had the highest survival rates. Read more
Regulated Rivers Research
Finland has about 159 000 kilometers of rivers, of which more than 90 % are regulated or otherwise modified. Thus, changes of these river systems must be taken into account in the management of riverine fish populations. Read more
Combining harvesting and conservation: the case of adfluvial brown trout populations
Finnish adfluvial brown trout stocks are endangered. One of the most viable populations lives in the Oulankajoki river system, Northern Finland - a joint water course between Finland and Russia. The ongoing research project is attempting to develop joint management and conservation actions between Finland and Russia to assure the wellbeing of these unique brown trout stocks. Read more
Farming of Eurasian perch in Kainuu Fisheries Research Station
The ongoing pilot project surveys the prospects of Eurasian perch farming in Finland, and aims to establish aquaculture methods for the efficient production of fish to marketable size. Read more
