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 is the importance of the oysters?
Oysters are a crucial component of global ocean health. These animals filter and clean the surrounding water and provide habitat, food, and jobs. In some places, oyster reefs can serve as barriers to storms and tides, preventing erosion and protecting productive estuary waters.
How do oysters help the ecosystem?
Oysters are natural filter feeders. This means they feed by pumping water through their gills, trapping particles of food as well as nutrients, suspended sediments and other contaminants. In doing so, oysters help keep the water clean and clear for underwater grasses and other aquatic life.
What do oysters do in the Bay?
The reefs oysters form provide important habitat for the Bay's fish, crabs, worms, and other organisms. Oyster are also prolific filter feeders that remove light-blocking algae from Bay waters, facilitate removal of excess nutrients, and improve water quality for other organisms.
Are oysters good for the ocean?
Oysters pull sediment from the water, making it less murky; they process nutrients like nitrogen and phosphate, which runs into the water after nearby farms are fertilized; and they reduce the growth of algae and plankton, keeping the water clear and healthier for other marine life.
Why do oysters spit water?
Unsurprisingly, this antic spitting is part of the oyster's ablutionary routine. Like most bivalves, the oyster draws water in and across its gills, directing any food particles into its well-hidden mouth.
What are oysters Chesapeake?
An oyster labeled simply Chesapeake is a wild oyster that could have been harvested from anywhere in the bay, but most likely in the upper Maryland end, which is where most wild harvesting still happens. It will likely be low in salinity, owing to the Chesapeake's huge freshwater load, and skimpy in size.
Are Chesapeake Bay oysters safe to eat?
Oysters commercially harvested from approved waters, packed under sanitary conditions, and properly refrigerated are usually safe to eat raw or cooked by healthy individuals but cooking oysters to an internal temperature of 140° F or greater for 4 to 6 minutes destroys the common microorganisms of public health concern …
Can oysters save Chesapeake Bay?
A single oyster can filter 50 gallons of water each day, significantly improving the health of the surrounding waterway. They're considered a keystone organism in the Chesapeake Bay, and without them, other species – including humans who rely of the bay for their livelihoods – would suffer.
Do oysters make water clear?
Oysters also make the water clearer as they clean. Clear water lets in more sunlight, and helps more plants grow on the seabed, encouraging life there.
