Oysters filter water for the rest of the community. They can filter up to 2 gallons (8 liters) of water in an hour. They are the most effective filtration system in the Chesapeake Bay. Before Europeans/ Americans started to harvest the oysters in this region, the amount of oysters in the Bay could filter the 18 trillion gallons of water in the Chesapeake in a matter of days, while the current population takes over a year.
An issue that was present in few specific cities in Maryland have now expanded throughout the entire state. The Chesapeake Bay, a large estuary that has an extremely complex ecosystem that is vital to important habitats and food webs in this area. The Chesapeake bay is arguably one of the most productive environments in the United States. Over the years, this bay has been in a decline of wellness. Pollution, contaminants, and many other factors are destroying the overall well being of these waters, and completely messing up the important ecosystem that has been built there. Although there is an extreme amount of Marylanders fighting for the restoration of the Chesapeake, there are also who are not.
The Chesapeake Bay, which derives from the Algonquin word Chesepiooc meaning “great shellfish bay”, has been around for a very long time. Approximately 35 million years ago, a rare bolide (a comet- or asteroid-like object) hit what is now the lower tip of the Delmarva Peninsula, creating a 55-mile-wide crater. The bolide created what geologists call the “Exmore Crater,” which they believe was as large as Rhode Island and as deep as the Grand Canyon. Although this bolide did not create the Chesapeake Bay, it helped determine that a bay would eventually be located there.
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 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
A fishery by definition, is “the occupation, industry, or season of taking fish or other sea animals (shrimp, squid, clams) and selling them for profit” (Webster Dictionary). Atlantic Cod used to be considered as one of the richest fisheries in the world. Atlantic Cod, scientifically known as,Gadus morhua, are heavily bodied, blunt snouted fish that are typically brown or grayish in color with a series of spots located on their bodies along with a pale lateral line. This species of fish have a schooling behavior when feeding but remain isolated when traveling. The Atlantic Cod once densely populated the waters of the Atlantic ocean, from Greenland to North Carolina. Despite the wide range in location, Atlantic Cod are a nonmigratory species
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.
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
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
Using a model they projected the outcomes of a 10-fold increase in existing oyster biomass. This resulted in a system wide reduction of surface chlorophyll, increased dissolved oxygen in summer-average deep water, and added to summer-submerged biomass by removing nitrogen. The influence on pelagic waters was limited. They recommend this de-nitrification method as a supplement to nutrient load reduction. (Cerco CF, Noel MR. 2007.)
Oyster Bay, Long Island, New York: a small community located on the north shore of the famous long island has been the set for many films and television shows, home to many historical people, a vacation spot with a rich and sophisticated night life, as well as much more, but more importantly it is my hometown. Being situated on a map at 40.7594° N, 73.5028° W, it can be found between Oyster Bay Cove and Mill Neck on the “Gold Coast”, miles off of Oyster Bay Sound. The town of Oyster Bay is roughly 170 square miles and the highest elevation of the town is around 180 feet.
In times of droughts the USACE’s top priority would be continuing the water supply for Atlanta residents which created panic for people dependent on the river flow (Pittman). Over the course of two years which had some drought periods, the amount of oysters harvested in Apalachicola Bay dropped by two million pounds (Lawns…). Florida’s governor in 2013 filed a lawsuit for Atlanta to use as much as water as it did in 1992 even though the city population has increased by two million. Georgia answered back saying that the oyster harvesting is low due to “drought conditions and illegal overharvesting” (Lawns…). Because of Georgia’s claim about the low oyster harvest, the Federal Department of Commerce awarded the Apalachicola Bay area $6.3 million dollars to restore oyster reeks and retrain the
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
Our watershed, the chesapeake bay stretches more than 64,000 square miles and is home to about 18 million people.The bay provides us with a lot of things like fishes,salt and water for farming etc. But, the bay is starting to get polluted and many organisms in the bay are dying because of sediments, algae blooms etc.
I just started working at Oyster Harbors Club a few weeks ago, but my experience there has been wonderful. It has been an honor life guarding on the beach, and getting to know all the families and the children attending camp. I enjoy working in such a friendly family environment, and I am excited to work next summer as well. My educational plans for the future consist of acquiring my bachelors degree in biology that would help me in pursuing a medical career as a doctor. My passion has always been helping others whether it is at work, making sure people are safe, or giving back to my community. After becoming a certified doctor, I plan on specializing in dermatology. I am a very hard
