Can US eliminate invasive species by eating them? So far, most Americans aren't biting

It seems simple: American lakes, rivers and offshore waters are filling up with destructive fish and crustaceans originally from other parts of the world, so why not control these populations by getting people to eat them?

The idea gained momentum recently from the lionfish, which invaded the Gulf of Mexico but was successfully marketed to restaurants and today appears to be in decline.

Businesses and scientists have struggled to repeat this apparent triumph with other species. Some, such as Asian carp, are not appetizing to Americans. Others, like feral hogs, reproduce too quickly.

Laura Huffman is the Nature Conservancy's director in Texas. She says eating invasive species "is not a silver bullet," but the idea can still "get people engaged in the topic and in the solution."
