SMOLTPRO is a four-year strategic project funded by the Swedish Research Council Formas, aimed at developing ecologically and ethically sound methods for supplementary rearing of salmonids.

Salmonid fish is an important natural resource in Scandinavia. Large numbers of hatchery salmonids are therefore released to compensate for losses in natural production caused by hydroelectric power exploitation and other environmental impact. However, conventionally reared hatchery fish have difficulties adapting to natural conditions and therefore perform poorly after release.

New research shows that modifications of the conventional hatchery environment can have positive effects on the development of hatchery reared fish, but their long-term effects on performance in nature are poorly known.

Our ambition

Using a multidisciplinary approach, we will evaluate the effects of modified rearing methods on smolt migration and survival, and its socioeconomic value. Experiments will be conducted in a series of full-scale model systems to evaluate the generality of effects across the climate zones in the Baltic Sea, the Kattegat and the North Sea.

Following a dialogue with relevant stakeholders, the results will be used to produce new guidelines for sustainable smolt production. The project is in line with the new strategic research areas Sustainable use of natural resources and Development of aquaculture launched by the Swedish Government and Formas.




  • To develop ecologically and ethically sound methods for supplementary rearing of salmonids.
  • To increase the socioeconomic returns of hatchery-produced salmon and trout in Sweden and Scandinavia.
