Abstract

May Cherax destructor contribute to Aphanomyces astaci spread in Central Europe?

Highlights

  • Increasing numbers of commodities traded all over the world result in deliberate or unintentional introductions of non-native species outside of their natural ranges (Hulme 2009)

  • The potential interactions of Cherax destructor with three Aphanomyces astaci genotype groups occurring in Central European freshwaters were assessed for the first time

  • As suggested by Unestam (1975), we confirmed an elevated resistance of C. destructor to the crayfish plague pathogen in comparison to European Astacus astacus

Summary

Introduction

Increasing numbers of commodities traded all over the world result in deliberate or unintentional introductions of non-native species outside of their natural ranges (Hulme 2009). Freshwater ecosystems are vulnerable to biological invasions (Ricciardi and Rasmussen 1999; Shea and Chesson 2002), with the key drivers of non-native species introductions being aquaculture and the associated trade of live organisms for direct consumption, ornamental purposes, or even research (Copp et al 2007; Gozlan 2008; Peeler et al 2011). All these pathways contribute to the introduction of exotic pathogens (Peeler et al 2011; Rodgers et al 2011). Even though import and stocking of North American crayfish are nowadays illegal in many European countries, additional non-indigenous crayfish species have been introduced through illegal introductions, garden pond escapes, and releases of aquarium or bait specimens (Chucholl 2013 and references therein)
