Jelly Fish Research Paper

People have always recognized jellyfish as that thing that will sting you while you are swimming, but now they will be known as a more severe problem than a simple sting. The jellyfish is causing problems with humans by disrupting electricity in Japan, Israel and Scotland as well as harming fisheries in the Black Sea. These issues are causing people to loose money that already have trouble just making enough to have simple necessities. These jellyfish blooms are a problem, but people have found a solution to the issues these monsters are

You may remember seeing the cute, seemingly harmless jellyfish in children TV shows when you were little. These innocent little creatures wouldn’t do a thing to harm anyone or anything. Right? While many people believe so, jellyfish are capable of electricity loss for days, and killing tons of people, due to an increase in their population. However, to stop these monsters in disguise, breeding another specific type of jellyfish, and taking away their resources will get rid of the overpopulation.

The most threatened region of the world is Southeast Asia where nearly 95% of the reef is affected. Countries in these regions use a couple different methods of harvesting fish for the food and aquarium market. The two most common destructive methods of overfishing are through the use of dynamite and cyanide. In fact, homemade bombs and dynamite are being thrown into the reefs killing, maiming, and stunning fish to be captured then sold. The blast radius from these small bombs are not only devastating the fish population, but are also shattering many large colonies of coral. Spraying or dumping cyanide into the reefs is also commonly used to capture fish. This fishing method is very wasteful, killing close to half of the fish before exportation. When the fisherman adds the cyanide to the water it not only harms the fish, but it is also poisoning the corals in the surrounding

The swarming populations of jellyfish are creating a problem for Commercial fishermen. Commercial fishermen used to have a thriving business. Although the jellyfish are eating all their profit, there may be a sweet solution

Jellyfish live mainly in the ocean, but they aren't actually fish -- they're plankton. These plants and animals either float in the water or possess such limited swimming powers that currents control their horizontal movements. Some plankton are microscopic, single-celled organisms, while others are several feet long. Jellyfish can range in size from less than an inch to nearly 7 feet long, with tentacles up to 100 feet long.

In 2014 it was acknowledged that the mid-Atlantic stock of tilefish was rebuild. That's just another way of saying the stock has increased in size to where the tilefish are safe from the dangers of the people who keep overfishing. Tilefish are the 36th stock to have been rebuild since 2ooo this just shows how many years its takes to fix something that we humans did.This is another reason why we should really stop overfishing even if not everyone can there should be less people doing

Blooms of Mnemiopsis jellyfish in the black sea are causing the loss of jobs for the local fisherman. These jellyfish are eating the eggs

As I researched how overfishing affects the ocean, I came across an article, from the credible source, World wildlife fund; titled “Overfishing”. As I read more about what it does to the ecosystem; there I learned that “More than 85 percent of the world 's fisheries have been pushed to or beyond their biological limits and are in need of strict management plans to restore them” ("Overfishing"). I thought to myself, that’s insane. As I continued to read I learned that most of the protein the world gets comes from those fisheries; most of the world depends on the ocean for the daily caloric intake ("Big-Fish Stocks Fall 90 Percent Since 1950, Study Says"). Illegal fishing is another culprit of the decline of the fish stocks worldwide. Illegal fishing can range from fishing fleets taking more than they can and ignoring protocols to recreational fishermen who don’t follow set regulations. All of these factors play a vital role in the declination of biodiversity not only at home but around the world ("Big-Fish Stocks Fall 90 Percent Since 1950, Study Says"). One specific way that fleet fishermen are using that destroys fish populations but also that actual ocean floor is, bottom trawling. Bottom trawling is when they rake the ocean floor to drive up the fish to the surface, thus annihilating the fish on all the levels of water ("Big-Fish Stocks Fall 90 Percent Since 1950, Study Says"). This is incredible affectful to the size of the haul, but it destroys the fishery and the

​One day you decide to go on a boat ride into the ocean. Once you are out you see hundreds of jellyfish. This can actually happen, it’s called a swarm. Jellyfish are very pretty but they can cause lots of damage. People and business are being affected by swarms of jellyfish but there are ways to control them.

There is a clear idea what the UBC study is trying to answer. The increase in jellyfish are interfering with many human activities. The first two articles describes UBC’s study on the jellyfish population growth and provided scientific evidence that human activity in marine habitats resulted in jellyfish abundance. The study mainly focuses on the increase in jellyfish population and states that 62 percent of the regions analyzed show this trend. At the end of the article however, they note that there was a decrease in the jellyfish population in 7 percent of coastal regions and the remainder of the marine ecosystem had no trend. This does not provide enough information to support the main idea that is jellyfish growth causes large problems. Neglecting this means that the article does not cover the relevant ideas fully. The

The overharvesting of marine organisms has been an ongoing issue since the mid 20th century, but has never been more prevalent until the present day. Fishing in the 20th century was a massively rapid-growing industry. Because of international efforts aimed at increasing the availability as well as affordability of foods rich in nutritional value, government intervention took place to increase the availability of fish species to the human population. With the implement of policies, government loans and support, there was a dramatically huge increase in industrial fishing—eventually making marine organisms the world’s primary source of protein-rich foods. This was good for a while, but obviously, good things never last too long. Overfishing, as defined by Pepjin Koster, occurs when more fish are caught then can be replaced through natural production (Koster, 2012). The balance of life in oceans is affected, and the social and economic well being of

There are concerns among environmentalists as the coral reefs around the world are dying. The reefs, which are one of the most diverse ones in the world, suffer from other factors such as overfishing and climate change. Scientists found that the waters contain ‘pulses’ of larval fish that restock the coastal fishes in the sea. They believe that since the South China Sea accounts for 1/10 of fish stocks for the world; the artificial islands should not be built as more than 1/4 of the world rely on it for food.

Even more shocking is the fact that one fourth of the fish caught are thrown back dead into the sea because they are either too small, or unwanted (Harris, Codur 1). This phenomenon is referred to as bycatch, uselessly killing millions of fish due to the indiscriminate fishing gear; take for example the estimated twenty eight million tons of bycatch left to rot in the ocean in 1994(Harris, Codur 1). Scientific statistics have shown that a sizable about of fish are being pillaged from our oceans to meet the demands of a few powerful consumers and with such shocking numbers, we can only assume that there will be repercussions.

Overfishing is a serious problem that often gets overlooked. In the article by Udy Bell, called “Overfishing: A Threat to Marine Biology,” Bell talks about how only 1 percent of the world’s oceans are marine protected areas (MPAs). MPAs not only help protect oceans by allowing habitats to recover from damage caused by overfishing but also allow fish to safely reproduce. Due to fishing fish faster then they can reproduce, many species of fish are going endangered or already endangered of being extinct. Species like whales, dungongs, sea cows, codfish, jewfish, sharks, and other marine vertebrates are examples of fish that are being overfished. Overfishing was addressed at the World Summit in Johannesburg, Africa in 2002 (Bell 17). At the World Summit, many experts in the field of overfishing agreed that the most effective way to battle overfishing is by creating and establishing more MPAs around the world. Although overfishing is a serious problem, there are ways to solve the problem like creating Marine Protected Areas.

Marine fisheries make up some of the largest ecosystems/habitats that span from the coastal regions all the way through the various oceans of the globe. In addition, the habitats and ecosystems of marine fisheries contain some of the most diverse groups of organisms worldwide just because of the sheer amount of the planet’s surface that the oceans cover. Although the range and diversity of marine fisheries are vast, they are declining at increasing rates. There are many factors that have led to this decline which include climate change, pollution, and the introduction of invasive species into particular habitats. However, the two largest factors behind the collapse of marine fisheries are directly correlated with human interaction with the marine fisheries. One is the overexploitation by the fishing industry, while the other is habitat alteration (mainly around the coastal areas) (Layman et. al 2011).
