Narrow-clawed crayfish in Finland: Aphanomyces astaci resistance and genetic relationship to other selected European and Asian populations
The narrow-clawed crayfish (Pontastacus leptodactylus) is an alien species in Finland with only a few populations reported from the southeastern region during the last century. We discovered a productive population in the lake Jängynjärvi, which is upstream from the previously reported wild narrow-c...

The narrow-clawed crayfish (Pontastacus leptodactylus) is an alien species in Finland with only a few populations reported from the southeastern region during the last century.

Preliminary studies indicated that this population is not infected with Aphanomyces astaci. We collected narrow-clawed crayfish samples from the lake Jängynjärvi population for both infection challenge and genetic studies, in order to investigate possible A. astaci resistance among this Finnish population and to evaluate their phylogenetic position that would enable us to speculate different scenarios of distribution pathways or origin of the population.
