2011 Switzer Fellow Kelsey Jacobsen's research focuses on Chile's Salmon Aquaculture Industry. Hear how she is working with local governments to ensure safe aquaculture practices for years to come.

But Beal says he has come up with a better way to grow lobsters in captivity. Through trial and error over several years, he has learned how to grow lobsters in a protected environment until they are several inches long — not big enough to be sold, but big enough to settle to the bottom when they are released and possibly to improve their survival rate.

Though the global economy has accelerated the process in recent decades by the sheer volume of ships, most from Asia, entering West Coast ports, the marine invasion has been in full swing since 1869, when the transcontinental railroad brought the first shipment of East Coast oysters packed in seaweed and mud to San Francisco, said Andrew Cohen, director of the Center for Research on Aquatic Bioinvasions in Richmond, Calif. For nearly a century before then, ships sailing up the coast carried barnacles and seaweeds. Read the full story

The prime culprit in all this is the green crab. And as Brian Beal explains, green crab populations can be hard to control. He's professor of marine ecology at the University of Maine in Machias. "Nobody really eats them and that's the problem," Beal says. "They're just so highly fecund, they have lots of eggs, there's no real predator that can keep them in check." Listen to the full story
