Negative Effects Of Aquaculture In The Mediterranean Sea

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

Shellfish require nitrogen to grow and while growing, filter the water, improving water clarity and removing biomass (Bricker et al., 2018). Harvesting the shellfish makes the removal permanent and in the case of the blue mussel in Sweden, a 10 by 200 m by 6m deep farm grows 140 to 180 metric tons of mussels removing almost 1400 to 1800 Kilograms of Nitrogen in 18 months (Lindahl et al., 2005). This same farm can filter about 50,000 square meters of surface water over the course of a year improving water clarity (Lindahl et al., 2005). Considering that the LNB encompasses over 500 ha of water, which provides plenty of space for aquaculture without conflicts with other users. Approval for a project like a mussel farm or other shellfish would require a purpose or business plan plus a variety of permits. Aquaculturists in Long Island Sound already grow oysters, which provides the same benefits as mussels, but takes a little longer to grow. Connecticut DEEP manages the permitting process in this area, providing a single organization to work with. The nitrogen removed from a single farm would go a long way towards mitigating the 88000Kg of nitrogen added every year, see figure 1. While some challenges do exist in getting started, LNB size provides ample space for an activity like shellfish aquaculture, which would start eutrophication reduction immediately, increase water clarity and provide a usable

Have you ever thought about what you are eating? You should do that from now on, as all seafood (with an exception of jellyfish) will be extinct by 2050. Seafood is becoming scarce, and humans continually do things that make matters worse, such as overfishing, illegal fishing, and more. In this essay I will merely state four of those many issues and how to fix them. One of the many issues is pollution.

This article, “Oceans of Pollution” is written by Dahr Jamail. He presents this article with many details to support his argument. Two main topics with support are used, which is how plastic is causing a great pollution affecting the fertility rates of the fish because fish can ingest tiny sizes of plastic therefore harming the creatures. As well, another topic in this article is the dead zone affecting the ocean, caused by natural environment, climate changing the temperature and human factors. This article mainly presents this article to the government to suggest for change and to humans, many who are biologists, who care about this huge problem. With the intensity of the ocean’s pollution, the article uses three rhetorical topics, pathos,

The habitats that are exploited to farm fish are becoming ineffective, as a result of disappearing mangroves. Humans should be protecting wild fish instead of over farming them. The issues caused by aquaculture are rendering the ecosystem unsustainable. In this chapter, we learned about aquaculture and all the various problems that come with it.

The ocean makes up nearly three-quarters of the planet 's surface and contains about eighty percent of the life on earth. Millions of people all over the world depend on seafood heavily as a primary source of food. Americans alone consumed as much as 15.8 pounds of seafood per person in 2009 (NOAA). This is a lot of fish. In fact, it is so much that many populations of fish are going extinct. At this particular rate according to National Geographic, scientist predict that the earth is expected to lose all of its current fisheries by the year 2048 (Roach). The overfishing of our oceans leads to unmanageable practices that will eventually cause many species of fish to become extinct.

People often take the ocean for granted due to its vastness since it makes up over seventy percent of the Earth, however the integrity of the ocean is deteriorating. One of the major, worldwide threats to the wellbeing of the ocean and its inhabitants is overfishing. Overfishing affects not only the ocean, but also the land dwellers. Many countries around the world depend on fish as their main source of food. Tons of fish are caught out of the sea daily, however, the rate that fish are being hauled is far too high where fish stocks are incapable of naturally recovering. There is a decline in population size of affected fish and some species have even faced extinction. Overfishing is the leading cause of ecological extinction, foregoing any other human disruptions to marine ecosystems, such as pollution, water degradation, and climate change (Jackson, et al). Overfishing causes an overwhelming devastation upon the oceans because it depletes food resources, disrupts the food web, and destroys habitats of aquatic organisms, due to this, overfishing causes an oceanic ecological collapse worldwide.

The food and aquaculture organisation of the United Nation’s (FAOUN) define Aquaculture as the farming of aquatic animals, which includes fish, molluscs, crustaceans, reptiles and aquatic plants for food and aquariums. Farming implies some form of interference

Can you predict the outcome of food or medicine resources if ocean pollution is not prevented or minimized? Throughout this research paper the different categories of pollution will be explained more in depth. Also there will be ideas or things we can all do to minimize ocean pollution and stop causing so much stress to the ocean’s ecosystem. It will also specify the importance of minimizing pollution in the ocean and how much damage it can cause. The ocean 's ecosystem is under much stress and many sources of pollution that is causing much harm.

The definition of aquaculture is simply the farming of fish, plants and shellfish as well as many more aquatic organisms. Aquaculture refers to the cultivation of freshwater and marine species, and includes land based and opens ocean production. Aquaculture can be compared with commercial fishing, aquaculture involves cultivating of fresh and saltwater populations under controlled conditions, while commercial fishing is the harvesting of wild aquatic creatures and can be seen more as a form of “hunting and gathering”.

Commercial Fishing has always been a means of making a lucrative living. So much so, that is one of the reasons that concerns have risen today. With the increase in the number of commercial fisherman within the U.S., it requires more fish to be fished from the seas. Over the years, changes in the fish stock population has become a serious concern. Commercial Fishing is also destroying our sea beds and marine life that lives on the sea floor of the oceans. Many times, the threats to marine life due to commercial fishing are not detected until the marine life has suffered a significant decline in numbers. Unless other practices are put in place, the impacts of regular fishing spots, bottom trawling and pollution will have a catastrophic

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.

Another global effect of overfishing is fish farming or aquaculture. It was first started to help preserve the ocean and hoped to help people to obtain a reliable fish source. Unfortunately, what many came to realize is the downside of fish farming. One example is water contamination, where consequently waste products such as foods eaten, feces and other dead fish, are all dumped into our main water supply which contributes to water pollution. Moreover, chemicals that are used to treat the fish farms like antibiotics and algaecides are all released into the ocean; which is a real cause for concern for our oceans. Fish that come from the fish farms are pumped full of drugs, to prevent sickness in the fish but this is not healthy for us to eat. There is also a great environmental impact which includes the fact that to sustain fish farms, portions of

Many people tend to not realize what goes on with the everyday life with oceans. Not just what occurs in the oceans, but what humans are doing to the oceans. One of the multiple negative impacts that humans have to the oceans include overfishing. Everyday, fish are caught by the hundreds because of humans, which plays a major impact on marine life. As the the days, months, and years go by, marine life within the oceans becomes less healthy due to overfishing by humans. Overfishing has been occurring for decades and if it continues to happen at such a great rate, fish in the ocean will become endangered or even extinct. “Close to 90 percent of the world's marine fish stocks are now fully exploited, overexploited or depleted” (“Time is

The demand for food across the globe continues to increase as the human population continues to increase. For human populations, particularly people in the poorest countries across the globe, fish is an important source of nourishment and food given the increase in the demand for food. As a result, fisheries catches represent a huge export of energy and mass that can no longer be utilized by trophic levels that are higher than those fished. Since fishing has been used one of the major ways by humans to meet the ever-increasing demand for food, it has contributed to widespread overfishing. The widespread overfishing has in turn resulted in the decrease in the global catch of fish. Furthermore, increased overfishing has become a huge threat to every species in the ocean and has largely contributed to the huge migrations by marine mammals in their quest for the left over fish. While the use of fish by human beings is not wrong, the whole eco-system in the ocean can be severely impacted when human take too much. In order to deal with this issue effectively, it's important to examine its causes, effects, and proposed solutions.
