Our research capitalizes on the unique opportunities provided by the relatively simple genetic architectures of several life history traits in fishes, combined with the strengths of commercially important fishes as models for functional genomic, ecological and evolutionary research. Our aim is to link genotype, phenotype and fitness of important life-history traits using approaches ranging from investigating the cellular-level processes in the laboratory to estimating reproductive success in completely natural populations. We also apply the knowledge we obtain for improving conservation and management of these species. Our research is funded by the ERC, the Academy of Finland as well as other local agencies.
