Determining Effective Strategies for Invasive Crayfish Management in Switzerland

Non-indigenous crayfish species (NICS) cause widespread ecological damage throughout European waterways. They negatively impact native species through competition, predation, and disease transmission. The Swiss Coordination Office for Crayfish was formed in 2014 to address this issue in Swiss waterways by conducting research, informing local governments, and informing the public. This office evaluated the effectiveness of different control methods through literature review, lab testing, and field barrier construction and testing.
