Public risk perceptions associated with Asian carp introduction and corresponding response actionsBiological invasion pathways are strongly influenced by human behavior. This research aimed to build new understanding about public perceptions and expectations for possible management responses that might be used after detection of Asian carp in the Laurentian Great Lakes. Although the species are as yet unestablished, our research worked to inform communication that could be publicly responsive in the event of an invasion. Our objectives were to: 1) determine public risk perceptions associated with Asian carp; 2) determine public risk perceptions associated with different types of management responses to an Asian carp invasion; and 3) identify types of risk-related information and communication that would influence community support for different types of eradication or control approaches. Objectives were achieved by using a two-phase approach. Phase one utilized an online, voluntary, self-administered survey with 2788 responses received from a convenience sample of Laurentian Great Lakes Basin residents. Phase two included three "Thinkshops" of fishing and boating stakeholders in southern Michigan. Across all hypothetical Asian carp invasion scenarios, the application of rotenone to a large area was the most frequently selected management response. When impacts from Asian carp and their management were discussed, study participants supported framing risks in terms of environment and economy. Insights herein provide new evidence that can help narrow the gap between how invasion risks are perceived and responded to by natural resource managers to reduce social conflicts over, and potentially address, invasive species threats more rapidly.
