The jellyfish is a horrible everyday monster that is very threating to everyone. As Rosalind Fonem stated, "For an animal that does not have a brain, a heart, or blood, jellyfish have a negative impact in many places in the world." It seems silly that it could cause this much damage but Rosalind Fonem explains many ways jellyfish cause damage in her article Jellyfish Take Over. Jellyfish may look interesting but they create much damage. This everyday monster causes fishing industries a lot of money each year because they are eating the larvae and eggs of local fish. This action from the jellyfish affects all local fishing industries and their families. This could be solved by using the Bereo species, this fish will eat the Mnemiopsis jellyfish creating a more fair and balanced …show more content…
Although they swim in the ocean, the jellyfish do not have many other characteristics of fish, which makes it unique. The tentacles are used to paralyze small animals. The tentacles contain a poison which is ingested into other fish and people. In the long run these jellyfish are unique yet damage lots of things.
The jellyfish cause fishing industries much money each year because they are eating the larvae and eggs of local fish. The Mnemiopsis jellyfish is located in the Black Sea and causes millions of dollars in problems. These jellyfish reproduce in large amounts and multiply into larger groups called blooms.This is why fishing industries lose millions of dollars each year.
Jellyfish also clog the cooling water filters. According to Steve Hays, a Plankton ecologist, the power plants had to be shut down because of the clogged nuclear power plants. This has occurred in Japan, Israel, and Scotland. Steve Hays quotes "Science data shows that over the past few years there has been an increase in swarms of jellyfish." Therefore, the increase in the amount of jellyfish created more chaos due to the amount of clogged water
Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,
Due to the demand many packaging for the fish can find its was back to sea, or when fishermen are out at sea they can leave their garbage. Many nets from the boats and gears can also be found in the water, that fish can later see as food, eat it, and die; this ties back to extinction in fish. There is much pollution and decline stocks in fish because it is very hard to regulate the seas. To fulfill the growing demand for seafood, many companies are forced to fish beyond areas that are supposed to be non-fishing zones. This is because there are hardly any laws or restrictions telling them where they can and cannot fish. Sally Driscoll and Tom Warhol report in, ‘Overfishing’, that itt wasn’t until 1956 where we saw our first regulation, the United Nations organized the first UN Convention of the Law of the Sea or the NCLOS which helped promote rights of all countries by establishing boundaries off shore. Meaning that some seafood fished in certain areas of the ocean cannot be sold in certain countries, and in some areas it is illegal to fish unless you have a permit from that country. Economy also helps make it harder to regulate the seas, in ‘Overfishing’ it is explained that Preisdent Barack Obama brought up Antiquities Act of 1906, that let fishermen expand their fishing areas. The United Nations FAO estimates that 25 percent of all fish trapped in nets are labeled unusable or not licensed for fishing by the
Scorpaenidae are mostly marine fish,very few found in fresh and brackish water. The family have around around 45 different genera and 380 different species. They are mostly found in the India Ocean and the Pacific Ocean. Most of them lives in coral, tropical reefs and shallow waters, warmer areas. Not all of the family fish lives in the shallow water, small portion of the Scorpaenidae live deep as around 7,000 feet. Just like most of the coral reef fish are, Scorpaenidae have camouflaged body. Their characteristic reflects their name, they have sharp spine that can sting other organisms. Their spine are covered with venomous mucus just like how some other kind of fish are covered with the venomous mucus. Their body are covered with scales. Generally speaking, the Scorpaenidae family fish have different number of spines over the course of the body. Most known type pf Scorpaenidae are lionfish and scorpionfish. Lionfish have preorbital bone with 3 spines, spines and third below the diagonal; , big mouth, end position, oblique fissure. Mandible, vomer and jaw bone with villiform teeth group. Gill openings are wide, tetrabranchiate membranes without the isthmus, pre-opercular margin with 5 spines. Body are ctenoid scales, round head. On the side, there are about eight to nine dorsal fin, fin spines and rays of an anal fin; five to six pectoral fins, they are large, round, and are branched from the upper fin rays. There are about one to five pelvic, sub thoracic; caudal fin rounded truncate. Reef stonefish are extremely camouflaged, they could look exactly like a rock when hiding for predation. The spines of Scorpaenidae are hard and rough, some of their fin spines have poison, can cause serious pain, swells and fatal wounds. Some of ...
The Red Lionfish (Pterois volitans) is an invasive saltwater predator that is increasing exponentially in the tropics of the western Atlantic (Benkwitt, 2013). The Lionfish invasion is causing a dramatic decline in native marine reef species due the gluttony of the lionfish.
Simply, overfishing depletes fish stocks. The consumer demand for fish has risen dramatically over the past decade or so, so much that fisheries are designing new and innovate ways to catch more fish, and at a faster rate to meet consumer demands. What fisheries do not realize, though, is that their removal of fish from the oceans is too great and far too fast for new fish stocks to be made. So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)
A documentary is an informative film that aims to position readers to accept one version of the events or topics expressed. All documentaries posses the ability biased and present an altered version of reality to persuade audience positioning. ‘Blackfish’ is a captivating and inspired documentary released in 2013 concerning the inhumane captivity and domestication of Orcas at SeaWorld for pecuniary advantage. The film, directed by Gabriella Cowperthwaite positions viewers to adopt a dominant reading position on the topic of whale subjugation. The documentary utilises techniques such as expert verification, emotive language and the humanisation of whales to position dominant viewers to accept the ideology that captivity is deleterious

Since nearly the beginning of human history fishing has been an integral part of the culture and survival of coastal communities. These coastal communities and cities have always been some of the most prosperous and successful because of the added resource of the ocean. In the beginning many areas were so densely populated with fish and shellfish that often a day’s worth of food could be caught by simply wading into the shallows. For example, some of the first English settlers to see the Chesapeake Bay described “The abundance of oysters is incredible. There are whole banks of them so that the ships must avoid them. . . . They surpass those in England by far in size, indeed, they are four times as large. I often cut them in two, before I could put them into my mouth” (Miller). This abundance had every appearance of being as infinite as the ocean that produced it but the reality was far different. Many fish stocks, including the oyster, stayed near these high levels even into the beginning of the industrial era. However the new rapid pace of technological advancement proved too much for many stocks to handle. Close shore stocks took most damage as they were the easiest to exploit. Those same oyster colonies that were once an obstacle for boats were nearly eradicated by “the 1890s harvests began to decline. Many oyster beds were destroyed and reefs had been mined away. By the 1920s, the boom was over…” (Miller). While catastrophes like this inspired many sustainable practices there are still fisheries worldwide that are headed for a similar end. Through ignorance and misinformation from the fishing industry most of the general public does not know that this is occurring. The following will serve to inform about the t...
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.
There’s No Real Good Guy In the movie, “Blackfish” we are exposed to the fact that the way orcas are treated at SeaWorld is worse than we are lead to believe. We see how they are forced to swim in tiny pools and how they can only be fed if they preform well. After seeing this it makes you feel like the only way to help these poor creatures is to jump on the animal activist wagon and to free all the whales like in “Free Willy”. But is that really the right way to go?
Many of the methods used in commercial fishing are very destructive to the aquatic systems. Industrial ocean trawlers scrape the bottom of the water, often dragging up the seafloor with them. This destroys the habitat and kills many of the bottom dwelling organisms that are vulnerable to these practices. There is also a large amount of marine animals that are unintentionally caught by the large nets. These animals are considered bycatch, having no value to fishermen and are usually killed. These large fishing vessels also add a significant amount of pollution to the water. Fishing vessels cause oil spills as well as discharging chemical elements and wastes into the water. The thousands of of trawlers that pass through Japanese waters create large quantities of water pollution that can devastate aquatic life by changing the chemical composition of the water and affecting all the organisms that inhabit these
Clincher: Unless we change the way we view our oceans, jellyfish might be the only seafood on the menu in the near future.
Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
The first cause of the marine extinction is coming from over-fishing and commercial fishing. According to Marine Extinction and Conservation, commercial fishing has
