Laukaa research infrastructure

The modernization of the research infrastructure in Laukaa was completed in 2022. Four new halls with equipment will allow high quality aquaculture research and a selective breeding programme to coexist in Laukaa.

Laukaa's research infrastructure is located in central Finland.  Water for the infrastructure comes from the upper, very good quality Lake Peurunkajärvi, which is also slightly regulated for water intake. The main area of operation is the river basin districts of southern Finland, apart from the Vuoksi river basin. On the coast, the area extends from the Gulf of Finland to the Kvarken.

Research on recirculating aquaculture is being carried out in Laukaa. The recirculation infrastructure consists of a large recirculation unit, where all fishtanks share a common water treatment technology, and a recirculation research and learning environment with 10 separate recirculation units. These units are miniature models of an independently operating recirculation plant with their own water treatment system. In addition, there is a recirculation unit, where the effluent is discharged into outdoor water treatment fields, from which the purified water can be recycled back into the recirculation unit. Innovative mobile recirculation solutions are also being piloted.

In Laukaa, the endangered stocks of valuable fish in the area are preserved and their eggs and fry are produced for further cultivation and stock recovery. The main products are roe and fry, most of which are delivered to private fish farms and ponds for further rearing. The Fish health service of the Finnish Food Authority classifies the plant as P1 (roe and fry can be safely supplied throughout the country).

In addition to being a living genetic resource  of valuable fish stocks, the Laukaa facility is particularly known for its research on fish farming methods and new species of food fish. One of the main objectives is to improve the competitiveness of domestic companies.
