The European green crab is classified by the International Union for Conservation of Nature as one of the world’s 100 worst invaders. Between their ability to eat 40 juvenile soft-shell clams per day, their practice of ripping up seagrass when burrowing, and their potential to produce 160,000 eggs at a time, green crab populations are exploding and decimating salt marshes, seagrass meadows, and other rocky intertidal ecosystems that support multimillion dollar shellfish industries. And climate change may make green crab invasions even worse. Today, we explore what problems green crabs create, why the issue is escalating, and a variety of solutions (including green crab whiskey!) that could help get populations under control. With special guest Dr. Alyssa Novak: Research Assistant Professor of Earth & Environment at Boston University.
