Oysters In New York Harbor

In The Oyster Question, Christine Keiner utilizes environmental, agricultural, political, and social history perspectives to investigate the Maryland oyster industry and its decline throughout history to answer the question if the oyster industry should be privatized. She offers opposing viewpoints from scientists, politicians and local community members. She has managed to connect scientific history with environmental history with local history to bring together a comprehensive overview of the problems both past and present of the Maryland oyster industry. I think that Christine keener does an excellent job, not without its flaws, of laying bare how science and preservation is necessary to be understood as local phenomena, manipulated by

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

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.

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

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

Studies have repeatedly shown that as oxygen concentrations decrease, the abundance and diversity of fish decrease (Breitburg). Fish kills, in which large numbers of dead and dying fish float to the surface or wash onto shore, are probably the most dramatic and publicly visible manifestation of hypoxia and nutrient over-enrichment of coastal waters(Breitburg). In addition to mass mortalities that are easily observed, high mortality of fish lacking a swim bladder can occur leaving little or no visible evidence of fish at the surface or littering beaches (Breitburg). With no fish, shrimp, or crabs the Louisiana fishing market takes a huge hit that the economy feels in a major way. The gulf accounts for almost one-fifth of the countries fishing landings, which total to be three billion dollars (Petrolia). Fishing is not only a major part of Louisiana’s economy but also its culture. Without wildlife in our waters microorganism are given more opportunity to grow leading to bacteria infected waters. These bacteria infected waters could cause major health risks for those who come in contact with

When ever you go to the beach, do you ever think about what can happen to an animal and the water when you leave a wrapper in the sand or a plastic bottle in the water? If you think about it, even a small piece of plastic can harm a fish. The fish could mistake it for food. This could potentially kill the fish. There are other things that people d that pollutes the ocean. An oil spill from a boat can get fish sick (Doc.2). Also, solid waste, plastics, glass, and foam (OI). Marine life can get trapped in any of these items (OI). There are many things we can do to prevent this, like, reducing plastic waste in stream, improve solid waste management, and increase, capture, and reuse (Doc.1). These are just a few of the many things we could do to

The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and

The Chesapeake Bay is a 200-mile-long estuary extending from Norfolk, VA to Havre de grace Maryland. On average this bay contains about 68 trillion liters of water. This bay is the largest estuary in North America. It inhabits more than 3,000 species of plants, animals, and fish. “Since the early twentieth century, the Chesapeake Bay has experienced serious environmental degradation. Problems include large reductions in sea grass, reduced amounts of finfish and shellfish (especially oysters and crab), seasonal depletions in dissolved oxygen, and increases in sedimentation.” (Atkins & Anderson, 2003) These changes are brought on by pollution (Eutrophication and Toxic Contamination), development, deforestation, and agriculture. And according

Spanning lengths over 300,000 meters, this it is a watershed that extends over six states, the District of Columbia, and meets the needs of over 15 million individuals. With its high rate of productivity, its economic and social importance to the surrounding areas, and its close proximity to the U.S. capital, the Chesapeake has the recipient of significant attention for quite some time(Boesch, Donald). One of the issues that threatens this important estuary is eutrophication. For the majority of the 20th century, research, guidelines, and management activity were focused on other issues like wetland loss, over harvesting of fisheries, infectious wastes, etc (Davidson et al, 1997). It took until the final quarter of the century for widespread realization to hit that eutrophication had deteriorated the Bay, with extreme consequences for the Bay’s resources(Malone et al., 1993). After awareness of the impact of eutrophication on water bodies began to increase, when it came to making policies and managing the Chesapeake Bay, eutrophication reduction took precedence over any other issues. As the Bay remains a very important body of water, the significance of understanding one of the major processes responsible for its degradation remains as well. This paper aims to understand the contributing factors of eutrophication in the Chesapeake Bay, with a special focus on the effects of air and

The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. The well-being of the ocean is constantly being threatened and needs to stop. When dangerous substances go into the ocean, ecosystems suffer and become endangered along with the lives of people and marine life. The importance of protecting and preserving the quality and biodiversity of the world 's coasts must be recognized because they are truly irreplaceable. If humans are not educated , and become careless about what is thrown on the ground or sprayed on lawns, disastrous effects follow when it comes to the condition of the ocean’s ecosystems, which can endanger life itself, leading to a problem only we can correct. There is historical evidence of ocean pollution, although the problem still shadows us today.

Globally, economies and ecosystems have always depended on oysters (Crassostrea virginica) for many benefits such as enhancement of commercially important invertebrates and finfish, stabilization of shorelines, filtration of coastal water, and removal of excess nitrogen. Oyster population and growth has declined drastically, and in 2008 many commercial leases were abandoned because oysters were dying before reaching market size. This study focused on the correlation of oyster reduction with water salinity and conchs. Just before this decline there was an increase in the crown conch (Melongena corona), which is the oyster’s predator. A prolonged drought in southeastern United States at this time could be a factor because of reduced inputs

The Pacific Oyster (Crassostrea gigas) has fallen ill to a disease named POMS (Pacific Oyster Mortality Syndrome) which is caused by the pathogen Ostreid herpesvirus-1 micro variant. (OsHV-1 micro variant). (1). This virus does not kill an infected oyster rapidly, however with the help of environmental factors, is causes death within 8 to 10 days of infection. The disease causes mass mortality in pacific oysters of all ages, spat (oyster larvae), juveniles and adults (7). POMS is exclusively affects Pacific Oysters and causes no health concerns to humans.

In Canada, the Grand Banks habitat is in “environmental degradation” (Connor and Taitano) due to bottom trawlers tearing up the sea floor displacing and destroying the vegetation at the seafloor and therefore disrupting the habitat of the small fish the cod prey upon (Connor and Taitano). Bottom trawls also disrupt the “breeding patterns of the cod.. Damaging fertilized eggs.. And greatly reducing the amount of young born” (Connor and Taitano). In the United States, the Gulf of Maine provides evidence of a loss of the young and old cod due to predation (Connor). Farming atlantic cod, like many fisheries are doing to replenish the atlantic salmon populations, have resulted in a breakout of the disease Yersiniosis (Connor and Taitano).The disease affects the fish’s intestinal tract before spreading throughout its body. The mortality rate with this disease is low, about 5%, however the illness prevents the affected cod from being sold at a market due to health violations (Connor and

Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.
