Blue Crab Essay

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

It is their home, their thriving place. According to the National WIldlife Federation, ¨The Bay supports 3,600 species of plant and animal life, including more than 300 fish species and 2,700 plant types.”. Not only does the wildlife depend on the bay, but humans do as well. The Chesapeake Bay contains a 64,000-square-mile watershed, this watershed provides large amounts of drinking water for us in Maryland, along with several other states. Everyday, the condition of the water declines, meaning the home for wildlife and our drinking water does too. The Chesapeake Bay Foundation pointed out that, ¨Toxic chemicals are constantly entering the Chesapeake Bay and its rivers and streams via wastewater, agriculture, stormwater, and air pollution. These harmful chemicals, such as mercury, PCBs, and PAHs, do not break down easily and persist in the environment for many years, impacting not just fish and birds, but humans as well.¨. How important does the restoration of the bay sound

Imagine living in a world where the weak are cast aside and you yourself are crippled, but your life is spared by love. Then your mother dies unexpectedly and there is no longer anyone protecting you. What will happen to you now? This is what Kira faced in the novel Gathering Blue written by Lois Lowry. Kira was born with a deformed leg and faces physical challenges because of it. At the beginning of the book, Kira’s mother dies from an unexpected illness and Kira is attacked by a group of women led by Vandara. Vandara claims that Kira should be taken to the field and left for the beasts, which the reader finds out later are not real. The Council of Guardian’s then spares Kira’s life and appoints her official threader of the Singer’s robe. She later meets Thomas, the Carver, and Jo, the

Have you ever thought about what it would be like not to be free? What would it be like not to be able to make choices? What would it be like not to be able to do what you want? It's scary to think about not being free, but even in the world today some people don't even have basic human freedoms. Lois Lowry shows us in her books The Giver and Gathering Blue what it would be like not to have freedom and how important it is that we have it.

of the food chain. This would cause their numbers to rise, which would lead to irreparable damage to the ever-fragile ecosystem.

The Bay is home to not only the Blue Crab but other forms of life from plants to small fish. If we do not restore the health of the Bay then the Blue Crab could actually go exscinded. Many animals cannot adapt to the human take over. Meaning they are un-able to live around and change to be able to live with the pollution that the humans have brought with us. Humans have causes the extinction of plants like the atamasco lily. If we do not restore the Bay's health the atamasco lily will not be the only thing that goes extinct. The Bay's health isn't just about the animals it's also about the water and the health it is in. Ph. levels in the soil have dropped causing the soil under the water to be less healthy due to

Ray McClain). The ‘farmed’ and the wild crawfish are both composed of the same species, the red swamp crawfish (Procambarus clarkii) and the white river crawfish (P. zonangulus). The more popular of the two crustaceans the red swamp crawfish, as it is caught more often is purchased more at the market. There are other crustaceans that are important to the basin besides crawfish, however. Blue crabs (Callinectes sapidus) are a vital resource in Louisiana’s seafood industry. The crabs are harvested by way of traps. In the case that the traps are lost or abandoned, they will continue to catch crabs. This is leading to a downturn in the blue crab population. Fish are also affected by the traps, as they are also caught. Despite the risked to the crab population, , the Marine Stewardship Council recognized the Louisiana blue crab fishery as the only sustainable blue crab fishery in the world in March of

California Blue is a novel about a seventeen-year-old boy named John Rodger. John is in his last year of high school in a small northern California town where the majority of the townspeople, including John's father, work in the lumber industry. As the youngest son of a father who was a champion athlete, John has always felt pressured to excel in his sport of choice, distance running. Because his father considers biologist's opposition to clear cutting of redwoods a threat to the timber industry and his livelihood, John's father also disapproves of John's interest in biology as a major area of study. John doesn't follow either of his father's wishes. In the middle of his senior year John learns that his father has leukemia and that

Temperature had a direct effect on oxygen consumption of crayfish, Orconectes propinquus. Crayfish acclimated to warm temperature (20 to 25 C) had a mean mass of 8.25g +/- 1.05. Crayfish acclimated to cold temperature (3 to 5 C) had a mean mass of 10.61g +/- 0.77. Oxygen consumption rates of 30-60 minute treatments were used and there was no significant difference between the two different treatments (t=0.48, df=58, P=0.70). The data from 0-30 minutes were not used because the crayfish were disrupted by transportation and the data were not normally distributed. The Q10 value was 1.05, representing that there was full compensation for oxygen consumption for the crayfish at two different acclimated temperatures. The oxygen consumption of crayfish was not affected significantly by two different temperatures (Figure 1).

Being considerate toward everybody and everything is the ideal goal that everybody hopes to achieve. Though the idea of being considerate is different depending on the person so reaching that point in the world is impossible to achieve since there is no baseline for that, we have many competing ideas as to what that could be. Some people see being considerate as being thoughtful of other people but others will see it as a deeper meaning with being courteous toward all living things on Earth and their belongings. There are so many different ways to be considerate and the readings of David Foster Wallace, Jessica Mittford, and Caitlin Doughty all have underlying messages of how people need to be more aware of what they are doing. Each piece

With the algae growing so close to the edge or shoreline they are constantly taking in the run-off or whatever may be on the shoreline. This makes it very bad for not just the algae but also the the water and species living down under. A lot of this pollution may come from the big city plants. Their disposals might just be fed right into the Chesapeake Bay and they probably do not care. This is a big problem all over the world, not just the Chesapeake Bay. (Decline of Submerged Plants in the Chesapeake Bay) Another reason to why there is such a decline in not just algae but other grasses is that the warming trend over the last 20 years, global warming. By the looks of it, the warming trend is not going to stop, so this may be a problem to deal with for a longer time. Natural diseases is another way the decline in algae and other grass plants is happening. Mostly dead organisms is the reason for these natural diseases. Once you get a bunch of bacteria and fungi, you will hope to get rid of the algae or grasses because it will most likely just end up making the Bay worse, and turning away species. The number of hurricanes the Chesapeake Bay takes does not help the cause. Hurricanes are affecting the salinity of the Bay. The salinity affects the growth and the amount that grows in a plant as well. (Decline of Submerged Plants in the Chesapeake Bay) The pollution can fall down into the water and you may find pollutants in the sediment. The sediment is home to many species. It can be very protective to large predators and large predators can possibly hide in there while they wait for an attack. Ways the pollutants are getting down there is carelessness by the fisherman and the people in charge of it to take

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 allusive bluefin tuna is one of the largest, fastest and highly sought after fish in the wild sea. The Bluefin tuna can weigh over half a ton, grow to over four metres in length, and dive to depths of 1,000 metres. They can reach speeds of 70 miles an hour and even raise their body temperature far above that of the surrounding water in order to traverse arctic waters. They are among the most ambitiously migratory of all fish, with some tagged bluefin being tracked swimming from North American to European waters several times a year. The bluefin tuna is unique, a perfectly adapted products of evolution. They are also dangerously close to becoming extinct (Brown). Today, the bluefin tuna has been fished out by 97 percent from pre-fishing

In the ecosystem organisms rely on each other for food and protection. The Food chain is like a pyramid you have the producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers. It’s an almost perfect balance and if any level were to just stop existing then the food chain would be destroyed. An example of organisms relying on others is an issue of isle royale were the wolves and moose population are in jeopardy. This relationship is important because without the other animal the population would die.

and green. Blue as discussed earlier was represented as the color of the God and other religious concepts, so the major incorporation of the color blue in the reliquary chasse indicated the spiritual significance it carried. Envisioning blue on the chasse unified people to Jesus Christ. Many of the reliquary chasse of the 12th century narrated a story; this individual one narrates the crucifixion of Christ. There are several key figures engraved throughout the exterior of the chasse, however since the crucial scene of the execution are shown on the front face of the chasse, that indicates that this chasse was primarily to be seen from the front rather than the sides. If viewed from the front, the top has three figures designed on it. In the center is the God the Father and on his either sides are two unknown saints. All three figures are represented in mandorlas however in different colors. The God of Father is displayed in the blue mandorla while the saints are shown in green mandorla. Here we can interpret a sense of hierarchy because the God of Father is shown in blue, which represents a divine color, however the saints are represented in green that is a mix of blue and yellow. So, blue still exists and represents divinity, yet the mixture of blue and yellow to produce a different shade of blue signifies that the God of Father is above and more important than the saints.
