Innovative Weaponry in the Fight Against AIS

In the fight against alien animals that invade and overrun native species, the weird and the wired sometime win.

Invasive species are plants and animals that thrive in areas where they don’t naturally live, usually brought there by humans, either accidentally or intentionally. Sometimes, with no natural predators, they multiply and take over, crowding out and at times killing native species.

Fighting Invasive Species

A new underwater robot is targeting the stunning but dangerous lionfish.  The robot, called Guardian LF1, uses a gentle shock to immobilize the lionfish before they are sucked alive into a tube. In its first public outing this month, the robot caught 15 lionfish during two days of testing in Bermuda. Top chefs competed in a cook-off of the captured lionfish which sells for nearly $10 a pound.

Asian Carp

U.S. Fish and Wildlife officials are using souped-up old technology to catch Asian carp, a fish that’s taken over rivers and lakes in the Midwest. They use a specialized boat – the Magna Carpa – with giant winglike nets that essentially uses electric current as an underwater taser to stun the fish, said biologist Emily Pherigo. At higher doses, the fish are killed and float to the surface. In just five minutes, they can collect 500 fish, and later turn them into fertilizer.
