DISTRIBUTION AND REPRODUCTIVE BIOLOGY OF AUSTROPOTAMOBIUS TORRENTIUM IN BAVARIA AND DOCUMENTATION OF A CONTACT ZONE WITH THE ALIEN CRAYFISH PACIFASTACUS LENIUSCULUS

Knowledge and Management of Aquatic Ecosystems, 2005
In Bavarian freshwater systems, the stone crayfish Austropotamobius torrentium is still present in many headwaters of Danubian tributaries. Since the 1960s an alien species, the signal crayfish Pacifastacus leniusculus, was introduced several times ...
