The specific research of our working group is focused on genetic aspects of aquaculture as well as the characterisation and evaluation of aquatic genetic resources in order to conserve their genetic diversity for a sustainable utilisation. To achieve this, the genetic structure and differentiation of cultured and wild populations of fish species that are already utilised or have the potential for future utilisation in aquaculture are analysed applying a variety of genetic marker types (mainly microsatellites and DNA sequence polymorphisms of mitochondrial and nuclear genes). The species range studied in former and current national and international projects is mainly comprised of common carp (Cyprinus carpio), tench (Tinca tinca), pike-perch (Sander lucioperca), Atlantic salmon (Salmo salar) and other cultured salmonids as well as sturgeon species from the Danube river basin.
