Sharks and Lionfish

This is an interesting National Geographic photo essay about the attempts of divers and scientists to train local Honduran sharks to prey on the invasive Red lionfish. It appears that the sharks need some coaxing, but once they 'figure it out', they'll hunt the lionfish on their own. As George Burgess accurately states, this learned behavior will help (a bit), but it will not ultimately rid the Atlantic of these "rats of the sea." From what I've read, lionfish cannot be caught by trawl but may take hook-and-line. The most effective form of irradication is by spearing. After that? Many now make their way to restaurants.
