Fish Genetics Laboratory (FiskGen)
At the fish genetics laboratory (FiskGen) we perform genetic analyses of fish and crayfish, as part of environmental monitoring, within research projects and on behalf of others. FiskGen is situated at the Institute of Freshwater Research at Drottningholm where we focus mainly on identifying the genetic population structure of resource species and endangered species. The Swedish Agency for Marine and Water Management, county administrative boards, municipalities, fishing associations, fisheries conservation area associations and fish hatcheries, engage FiskGen. Welcome to contact us!
Most fish and shellfish species are divided into genetically distinct populations (local stocks). Knowledge of species’ genetic structure is important both for long-term sustainable fish management and for preserving genetic diversity in our fish fauna.
Effects of fish stocking
We also study genetic and ecological effects of fish stocking, and investigate how fishing may affects important traits such as growth and age at reproduction. We further monitor the genetic status of endangered species and cultivated stocks, together with our clients and in collaboration with our ageing laboratories.
At FiskGen, we primarily use so-called microsatellites as genetic markers. Species analyzed so far are salmon, trout, pikeperch, grayling, catfish (wels), char, whitefish, vendace, eel, crayfish, eelpout and flounder. Often there is access to genetic reference data sets from previous studies, which provides increased opportunities to study various questions.
