Deteriorating environmental conditions
In the 1970s, the Chesapeake Bay contained one of the planet's first identified marine dead zones, where hypoxic waters were so depleted in oxygen they were unable to support life, resulting in massive fish kills. Large algae blooms, nourished by the runoff of farm and industrial waste throughout the watershed, prevent sunlight from reaching the bottom of the bay. The resulting loss of marine vegetation has depleted the habitat for many of the bay's animal creatures. One particularly harmful algae is Pfiesteria piscicida, which can affect both fish and humans. The depletion of oysters due to overharvesting and damaged habitat has had a particularly harmful effect on the quality of the bay. The bay's oyster industry has also suffered from two diseases: MSX and Dermo. Oysters serve as natural water filters, and their decline has further reduced the water quality of the bay. Water that was once clear for metres is now so turbid that a wader may lose sight of his feet before his knees are wet.
Efforts of federal, state and local governments, working in partnership through the Chesapeake Bay Program, and the Chesapeake Bay Foundation and other nonprofit environmental groups, to restore or at least maintain the current water quality have had mixed results. One particular obstacle to cleaning up the bay is that much of the polluting substances arise far upstream in tributaries lying within states far removed from the bay itself.
The Chesapeake Bay, shared by Maryland and Virginia, is famous for its blue crabs, and they are one of the most important economic items harvested from it. In 1993, the combined harvest of the blue crabs was valued at around 100 million US Dollars. Over the years the harvests of the blue crab dropped; in 2000, the combined harvest was around 45 million dollars. In 19__needed] the Maryland Department of Natural Resources created stricter guidelines for harvesting blue crabs to help increase populations. These include raising the legal size from 5 to 5¼ inches (from 12.7 to 13.3 cm) and limiting the days and times they may be caught. While blue crabs remain a popular food in the Chesapeake Bay area, the bay is not capable of meeting local demand, so crabs are shipped in from North Carolina, Louisiana, Florida and Texas as well.

I admit that they are only running medium so far this season,very few #1's compared to last summer. We caught over 2 bushels in Annapolis ,Maryland a few miles from the Bay bridge 2 weekends ago in 6 1/2 hrs. The prices at Seafood/Crab houses here in Maryland are ridiculous though..$156-$190 a bushel for #1 males and $110 for females...Virginia south of the Chesapeake Bay isn't doing any better according to the commercial crabbers I've talked to.
