Chesapeake Bay Blue Crabs
Maryland 's icon, the blue crab, has been fading away in Chesapeake Bay . Last year Maryland saw the lowest harvest (22 million pounds) since 1945. Just four decades ago the bay produced 96 million pounds. The population is down 70% since 1990, when they first did a formal count. There are only about 120 million crabs in the bay and they think they need 200 million for a sustainable population. Overfishing, pollution, invasive species and global warming get the blame.
