Can US eliminate invasive species by eating them?

HOUSTON (AP) — It seems like a simple proposition: American lakes, rivers and offshore waters are filling up with destructive fish and crustaceans originally from other parts of the world, many of them potential sources of food.

So why not control these invasive populations by getting people to eat them?

The idea has 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.

But 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 to make a dent. And then there's the question of whether turning them into sought-after cuisine undermines the larger goal of eliminating them.
