Lynnhaven River Oysters Research Paper

The author of American Catch, Paul Greenberg starts us on a journey through america's seafood industry from the early days of abundant seafood to the present condition of our fisheries. America has about 94,000 miles of coast and about 3.5 million miles of rivers, but about 91 percent of our seafood is imported. Here in America 39 percent of citizens call themselves coastal folk, but Greenberg argues we have lost touch with the complex ecosystems of the nation’s shorelines. Estuaries and salt marshes are strange crossroads where salt and freshwater currents meet to be home for oysters, shrimp, and crab. They are also home of dozens of varieties of fish. Greenberg complains about our nation’s destructive relationship with its own shoreline and tells Americans they must desire to “build a bridge back from the plate back to the estuary. This requires us to not just to eat local seafood. It requires the establishment of a working relationship with salt marshes, oyster beds, the natural flow of water from river to sea, and the integrity of the ocean floor.”.

The Chesapeake Bay is the largest estuary in the United States. About half of the Bay’s water volume comes from salt water from the Atlantic Ocean. The other half drains into the Bay from its enormous 64,000-square-mile watershed. Estuaries are among the most productive environments on earth, creating more organic matter each year than similarly-sized forests and agricultural areas. Estuaries also provide diverse habitats for wildlife and aquatic life, protect our communities against flooding, reduce pollution of waterways, and support local economies through commercial and recreational activities. Thousands of species

The word Chesapeake, although there is some scholarly dispute, likely means “Great Bay of Shells” or “Great Shellfish Bay” in the language of the Algonquian Native Americans (“Oyster History”). This translation is appropriate and accurate to anyone familiar with the Chesapeake Bay and its rich history of oysters. The Chesapeake Bay is the largest estuary in the United States with over 150 rivers and streams flow into its basin. It measures roughly 200 miles in length, 3.4 to 35 miles in width and stretches across six states. The bay is home to over 2,700 plant and animal species, making it one of the most complex and productive estuary systems in the world (“Facts and Figures”). However, one species

Oyster reefs, giant populations of oysters, provide habitats for many other types of organisms such as worms, snails, sea squirts, sponges, small crabs, and fishes.

Do you know that Maine is famous for lobsters because it harvests the majority of lobsters in the United States? The population reached to 1.336 million people living in the state of Maine. And the total area of Maine is 35,385 square miles, also known as the biggest state with the most land from the original 13 colonies.

With oxygen levels in the dead zone being so low during the summer months marine life is almost nonexistent. This not only hurts the wild life of Louisiana’s coast but, also its economy and fishing based culture. In the future with the normal levels of oxygen returning to our gulf we can hope to see wild life slowly but surely returning. Also there is hope for the conservation and growth of the wetlands through the nutrient rich canals developed, enhancing Louisiana’s economy, culture, and

The native oyster of the Chesapeake Bay is the Eastern oyster; also known as the Crassostrea Virginica. One of the many diseases found in the Eastern oysters are: Dermo disease and multinucleated sphere X disease (Graczyk, et al, 2006). Fayer, et al (2010) found that even if frozen oysters were contaminated with feces they could still survive. As stated by Graczyk, et al (2006), the oysters contain human enteric pathogens. Oysters contain a bacterium that can clean the bay naturally by itself. Since the oyster’s population decreased dramatically it takes longer for the bay to be cleaned. Strickland (2009) stated “the oysters used to be able to clean the water in the bay with in three days but now it takes up to an entire year to get the job done”. Graczyk, et al (2006) stated that “due to over harvesting in the Chesapeake Bay Eastern oysters are becoming at a point of

Apalachicola Bay is located on the Northwest coast of Florida and has been called the heart and soul of North Florida. The oysters produced at the bay are undoubtedly superior and are considered the finest in the nation, according to New York Times (New York Times, 2002). In addition, the bay is one of the most productive estuaries in the country. However, the total harvest dropped to around 1 million pounds in 2013 and the National Oceanic and Atmospheric Administration declared a fishery disaster on the bay (Alvarez, 2015). The effect on oystermen's life is even worse. They complained that they are not able to pull out enough oysters to pay for their boat gas.

Eelgrass beds in particular are being harmed where European green crabs are abundant, because they are the primary habitats for this invasive species. The European green crabs invade these eel grass beds when they are searching for prey in the matter that has settled at the bottom of the water or excavating to make burrows, this is done by cutting the roots of the eelgrass, which destroys this ecological habitat. European green crabs have preyed on various marine life such as species of mollusks, crustaceans and fish. The primary species that European green crabs prey upon being shellfish. Shellfish (oyster, clam and scallops) being their primary source of nutrition (GOV, 2016) is an issue because they then create competition for food amongst other species such as lobster and crabs which are native to the habitat the European green crab has invaded. Their secondary source of nutrition comes from crustaceans such as crab, crayfish, lobster, prawns or shrimp. Additionally, Studies have shown that European green crabs will prey upon Dungeness crabs of equal or lesser size (Peters et al. 2004). This means that European green crabs are capable of displacing other crabs in the competition for space, food and habitat. Recently, a study was conducted which showed a 40% drop in Manila clam harvest since the European green crabs’ arrival in North America (pleus, 2017). Carcinus maenas

Today’s eastern oysters range from 3 to 5 inches in length, sometimes as much as 8 inches, although the oysters present during the colonization of the New World were documented to grow much larger (“Oyster History”). Oysters have many great characteristics in regard to their utility for humans as well as wildlife. The build ups of oyster bars, reefs, and beds provide habitat for many aquatic lifeforms and the filtration capabilities they possess is quite remarkable; as filter feeders, oysters feed on phytoplankton and small organisms while removing nutrients from the waters the inhabit, leaving them clear and pristine; just one oyster can filter more than 50 gallons in a day (“Oyster History”). Alas, it was a palatable constitution that made the eastern oyster so popular, creating an extensive economy based on its harvest. Unfortunately, this considerable popularity would ultimately bring the oyster’s

Chesapeake Bay, the largest North American estuary, where many watermen have successfully made a living by harvesting the plentiful amounts of seafood. Each year, millions of people are attracted to the bay for the different recreational activities that include hunting, fishing, and boating; this alone greatly contributes to the economy of Maryland. The professional fishermen here rely on large populations of these sea creatures to thrive, and remain large in number. If these numbers were to drop due to lack of food, caused by water pollution, then the fishermen that capture these creatures for a living, would begin to struggle to support their families. One way that the food source of these animals would dramatically decrease, would happen

The Annmarie Sculpture Garden and Arts Center, more commonly called “Annmarie Gardens”, plays host to numerous cultural events in Calvert County. The sculpture garden itself covers over 30 acres of woods and fields beside a creek stemming from the Patuxent River. While the various, annual events often feature works from various local artists, local musicians, or even local businesses, Annemarie Gardens also plays host to a wide array of permanent pieces that have become treasured works to the residents of the area.

The population of Virginia River Snails (Elimia virginica) living in the riffle microhabitat is less than the estimated population living in pools. The t-test between the riffle and the pool snail populations resulted in a t-value of 2.39, which is larger than the accepted value of 1.96, which means there is a discernable difference in the two population sizes. The density of snails in the pool was calculated to be 1.21 snails m-2, while the riffle density was 0.55 snails m-2 (Table 1).

. As seen in the video, an oyster’s ability to filter feed gives them the helpful ability to clear up murky waters. In the experiment, the oysters started reducing the turbidity of the water within minutes of being placed in the tank. Although these result would most likely not occur this quickly on the large scale, in is indisputable that the oysters would reduce the turbidity of the water; allowing the plants to photosynthesize once again.

Benefited from the South Town has a high quality of inner bay waters including salt and fresh water, oysters here is rich and fresh. Generally oyster will be sent to the
