Lessons Learned
• Exercise illustrated the successful implementation of the Mutual Aid Agreement and overall dedication to regional AIS response efforts
• Grass carp eDNA results exhibited temporal variation – time lag of sample processing made planning for traditional
gear sampling difficult
• ICS was an effective framework for planning and implementing an AIS response effort, but need to tailor framework for fisheries response
