The Chesapeake Bay watershed spans six states and the District of Columbia. Within this watershed are several large cities, including Cooperstown, N.Y.; Harrisburg, Pa.; Baltimore, Md.; Washington, D.C.; and Norfolk, Richmond and Charlottesville, and the bay supports more than 2,700 species of plants and animals.
Five years after the Chesapeake Bay blue crab fishery was declared a federal disaster an annual scientific survey shows the population is far below the previous year, but scientists are not too worried.
Scientists from Virginia and Maryland conduct the so-called "winter dredge survey" while crabs are burrowed in the mud. Last year a baby crab boom led to the highest count in 20 years.
