Like the lionfish, this prawn has been successfully turned into gourmet food, because it is similar to shrimp, Huffman said.
Similar practicalities can affect invasive plants. The Himalayan blackberry is known for crowding out other shrubs and reducing the size of pastures. Although it is delicious, it's also thorny and requires time-consuming hand picking that makes large-scale harvesting difficult.
Feral hogs can also be tasty, but they reproduce so quickly that hunting doesn't make a dent in the population.
Jean-Philippe Gaston, chef at Haven and Cove Restaurant in Houston, started serving lionfish because he wanted to help reduce its population in the Gulf. Now the taste alone keeps it on the menu.
