Even with population growth, however, some areas continue to experience overfishing. Virginia’s total wild oyster harvests have remained stable at around 600,000 bushels for the past several years, partly due to a rotational harvest system.
How many oysters are left in the Chesapeake Bay?

How are scientists trying to help the oyster population in the Chesapeake Bay?
But over-harvesting, disease, pollution and habitat loss have led to a severe drop in oyster populations. Scientists and resource managers are working to manage harvests, establish sanctuaries, overcome the effects of disease and restore reefs in an effort to bring back the bivalve.
Why are oysters important to the Chesapeake Bay *?
Oysters are an important part of the Chesapeake Bay. They filter and remove excess nutrients like nitrogen from the water and they grow in reefs that provide habitat for fish and crabs. Oyster reefs support not only the ecosystem, but the economy.
What happened to the oysters in Chesapeake Bay?
But decades of overharvesting, pollution, and disease have contributed to the decline of oyster populations in the Bay.

What will happen if oysters go extinct?
Oysters improve water quality and clarity, preventing large scale algal blooms and the potential consequences of mass fish mortality and deadzones due to depleted oxygen. Removing oyster reefs increases wave energy and erosion of saltmarshes and the corresponding coastline.
What country eats the most oysters?
France is the No. 1 consumer and exporter of oysters in Europe producing 150,000 tonnes every year. King Henri IV (1553-1610) was said to eat 300 of them at a time, his grandson Louis XIV had them delivered fresh daily to Versailles or wherever he was and was known to eat six dozen at a time.

What percent of oysters is in the Chesapeake Bay?
By 2011, the oyster population in the upper Chesapeake Bay was estimated to be 0.3 percent of population levels of early 1800s due to overfishing, habitat loss, and disease, according to a study led by Mike Wilberg, a fisheries scientist with the Chesapeake Biological Laboratory.
Why are oysters making a comeback?
Oyster reefs are making a comeback–by protecting coasts from the ravages of climate change. Oyster reefs are natural barriers that protect shorelines from erosion, tides and storm surge. They knock down the height and force of waves, but they’ve been decimated by a century of overharvesting and worsening water quality.
