Perceptions on the genetic biocontrol of invasive carp

Common carp ( Cyprinus carpio ) is an invasive species that damages native aquatic ecosystems. Advances in genetic engineering have led to novel genetic biocontrol methods that have the potential to aid in the control of carp and other invasive species. Research and development of these technologies is proceeding in parallel with outreach activities which aim to inform and engage the public. Public perceptions on the ethics, economics, and policy decisions surrounding the possible application of genetic control technologies are important in decision-making processes. Here we report results from a survey of more than 1,300 adults that measures the perceptions of risks, benefits, and overall comfort with a panel of existing and proposed carp control methods. Our population sample largely agrees that carp control is an important issue that demands action. We observe trends suggesting that comfort levels with the possible future implementation of genetic biocontrol for common carp are strongly influenced by the perception of benefits compared to other methods, in particular effectiveness and environmental safety. No statistically significant correlations between comfort levels and river/lake use habits nor demographics are observed. There is a need for further research to identify how respondents from similar backgrounds come to different knowledge and attitudes on the matter.
