Overall, we reveal that A. astaci infection affects signal crayfish to a much greater extent than previously considered, which may not only have direct consequences for invasions, but could substantially affect commercially harvested signal crayfish stocks worldwide. Invading hyphae are surrounded by melanin, which is deposited as a result of the hosts immune system responding to the infection. Freshwater Crayfish, 12:303-312, Oidtmann B, Thrush M, Rogers D, Peeler E, 2005. Traditionally, five crayfish species have been considered indigenous to Europe: Of these, it is mainly Astacus astacus and Astacus leptodactylus that have been exploited for harvest.
