Research Paper On Overfishing

This happens when they become overly stressed especially when exposed to warmer than normal temperature and excessive sunlight” (“Coral Bleaching- Essential Facts”). Although the coloring of the coral may not seem too important, it is. The Great Barrier Reef is home to more than “1,500 species of fish, 411 types of hard coral, one- third of the world’s soft coral, 134 species of sharks and rays, six of the world’s seven species of threatened marine turtles, and more than 30 species of marine mammals” (“Australia’s Great Barrier Reef under Threat”). The coloring of the fish species correlates with the coloring of the corals in terms of survival for the species. Gradually, certain species of the marine life that live in the Great Barrier Reef have adapted to the colors of the reefs to camouflage themselves which ultimately helps them survive and decrease the threat of predators. With the coral turning to a white, dead looking color, those fish that have adapted to the color now stick out predators become a stronger, more direct threat to them. Over time, this will change the Great Barrier Reefs ecosystem because certain fish populations will sharply decrease, in some cases even go extinct, while other populations will

A food web consists of all food chains of an ecosystem. A food web is a diagram which shows the transfer of energy between species. Energy is transferred through food; therefore, food webs basically show which fauna eats which. Food webs are organized into layers of who eats who called trophic levels. The bottom trophic level of a food web is the producers, the second being the primary consumer, then the secondary consumers, tertiary consumers and the final trophic level being the decomposers. The ecosystem of the Great Barrier Reef is a fragile balance, with a food chain that has several points, in which each one is reliant on one another. The Great Barrier Reef’s coordinates are 18.2871° S, 147.6992° E. The Reef has a huge amount of flora

When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely. Thus it is much better to prevent coral bleaching than to accomplish its recovery which may take many

Coral Bleaching is caused when elevated seawater temperatures result in extensive coral loss. When the water becomes too warm coral will expel the algae living in their tissue, causing the coral to turn completely white. Pollution from urban or agricultural run-offs, sedimentation from undersea activity like dredging, and changes in the salinity are other contributors to coral bleaching. Although coral can survive the bleaching they are under more stress and are subject to mortality. This issue is not a new problem; coral bleaching has had a substantial effect on coral for many years. “In 2005, the U.S lost half of its coral reefs in the Caribbean in one year due to a massive bleaching event”(National Ocean Service). Another article states that in January 2010, cold-water temperatures in the Florida Keys caused a coral bleaching event that resulted in some coral death. Researchers have evaluated the cold-stress of the water will make coral more susceptible to disease, in the same way warmer water impact coral. Luckily there are things that we can do to help stop this

It would effect everything on the planet, plants would be less able to produce the suns energy and living organisms would be in big trouble. A short term effect would be decreasing plant populations and a long term effect would be a decreasing population of every organism on the planet.

As predators in their ecosystem, Great White sharks help maintain the coral reefs and seagrass habitats. Recently, because of the downturn of sharks, those coral reefs and seagrass

The Great Barrier Reef is actually the largest living thing on Earth. In fact, it can even be seen from space. The only problem with reefs is that they can only survive under a certain temperature range. If the temperature is too low or too high for the reefs, this causes the algae, which gives the coral their beautiful and bright colors, to leave the coral, and therefore causing the coral to become bleached (National Ocean Service). This is exactly what has happened this year. Data has recently been released that El Niño has caused complete bleaching of the Great Barrier Reef (The New York Times). Let that sink in, the World’s largest living thing, that has been around for about 500,000 years, is dying this year. People need to realize that

When we are children we grow up watching movies that transport us to another world. Take Disney movies, typically Disney movies transport you to a faraway land with interesting individuals that tend to on adventures; take Disney’s motion animated picture The Little Mermaid, within this movie we are given the opportunity to see how living underwater is “better”. That if you living on land there are many problems you generally would not find under the sea. Although this is an animated motion picture utilized to promote happiness in younger generations something interesting to note is that not everything under the water is better. Even though we have words such as: “calm”, “gentle”, “rebirth” etc. that are associated with the sea; within recent years the sea and everything within it are changing. There has been an increase in the demand for fish, with such high demand the fish industry are utilizing extensive measures in order to meet said high demand.

The FKNMS is located off the tip of Florida containing over 1700 islands. These chains of islands are coral reefs that are just south from the Key Biscayne and extend southwest for approximately 126miles. These islands end about 90 miles north of Cuba. These islands are not suitable for people to live on because of there size. The FKNMS covers over 2800 square nautical miles. The FKNMS was established due to the demise of the coral reefs in the Keys. Low water quality, decline in coral reef habitats, and oil drilling eventually lead President George H. Bush to establish the FKNMS on November 16, 1990. FKNMS also contains the Key Largo and Looe Key sanctuaries, which were facing the same environmental challenges.

Coral reefs are communities of living organisms. They are made up of fishes, plants, and many other creatures. They have been around for millions of years: less than the 0.1% of the world’s ocean floor Is covered by coral reefs, however they grow very slowly, from 0.3 cm to 10 cm per year. The reefs we see today have

Overlooked and often forgotten, wilderness is surrounding the envionments humans live in. Wilderness does not have to be a untarnished and completely protected. Just as families have a place to call home, wilderness provides a home and a place of refuge for animals and plants and other non human living organizims. They make up the balance needed to sustance the wilderness. How humans and wilderness intact is what will cause florecment or produce neglect. Neglect will lead to long term negative consequences that would impact both humans and the wilderness. On the surface in most wilderness areas in may seem that life in the wilderness in well and with continues protection will go on. Although, an area of wilderness has been forgotten and is being abused. Thoughforgotten that wilderness needs a home just has much has humans.

Zooxanthellae’s response to thermal stress conditions and the effects it has with its symbiotic relationship with Coral Reefs

The coral was so weak and brittle, with only a little movement of water it withered away into a fine dust of calcium carbonate shells and skeletons. The acidic water wiped out of all the coral to almost extinction. Bothered by what I saw on this trip I headed up to the boat to report my findings to the unesco.

In order for a coral reef to be productive and healthy, the water quality in the ocean should be maintained. Water quality not only affects coral reefs, but the other organisms that live on it and are involved with the natural food chain. Some of the factors that can influence water quality are nutrients, temperature, salinity, dissolved oxygen, turbidity, light, and chlorophyll present. Water is essential to every living organism because it helps with respiration, maintaining body temperature, digestion and provides energy. This experiment involved taking water samples from Ferry Reach off the BIOS dock and analyzing different factors to determine general conclusions about how water quality affects reef ecosystems.

Therefore, the impact of overfishing and illegal collecting of coral may destroyed the social and economic well-being of the coastal communities who depend on fish for their way of life. Beside, it is also direct overexploitation of fish, intertebrates, and algae for food and the aquarium trade, removal of a species or group of species impacting multiple trophic levels, bycatch and mortality of nontarget species, and change from coral to algal dominance due to reduction in herbivores (Reef Resilience Organisation,
