In 2010, the National Oceanic and Atmospheric Administration campaigned for people to "eat lionfish" to counter their introduction to the Caribbean.
Eating invasive species has been suggested by people such as ecologist Joe Roman as a way of reducing their numbers. This is a list of cases where this has been suggested, tried and/or is now established.
