Biodiversity and conservation

A rich biodiversity increases an ecosystem's ability to cope with change and is absolutely central if our oceans, lakes and watercourses are to be able to deliver their ecosystem services. SLU Aqua works with questions about how biodiversity can be preserved; such as fisheries regulations and restoration, but also with threats to it; as invasive species, climate and human impact.

Pink salmon in Sweden

Pink salmon is an alien species in Sweden. SLU is mapping its distribution. Help us by reporting pink salmon sightings!

Genetics of Baltic salmon

By DNA-analyzing salmon scales, we investigate the genetic effects of the large-scale salmon restocking that has taken place in the Baltic Sea from the beginning of the 20th century.

Save the noble crayfish

In Sweden there are two species of freshwater crayfish: the noble crayfish (Astacus astacus), and the introduced signal crayfish (Pacifastacus leniusculus). We work to preserve the noble crayfish.
