Recommended: Shark decline and its effects
With such booming fishing industries, there are several species of fish out there that can handle the effect of human influences with proper regulations. Although, sharks are not one of these species. Shark finning is an act of catching sharks and harvesting the fins off of them while they are still alive. After the process, they are let back out to either drown or die of bleeding out, and it’s beginning to become out of control. Shark finning should be more heavily regulated due to the increase of illegal demands in the economy for shark fins, the drastic decrease in shark populations, and the negative impacts the low number of sharks cause to the ecosystem around the species. Early on since the 14th century, shark fin soup has been a …show more content…
With the increased demands due to the large paycheck, this correlates to how well these poachers are actually doing their job. Over the years, research has estimated, “Approximately 100 million sharks are killed globally each year,” and also that, “some shark populations have decreased by 60-70% due to human shark fisheries,” (Fairclough 4). In addition to the increased rates of shark finning over the years, the low rate of reproduction within the shark population does not help their case. It causes a hardship in the species; not being able to replenish their numbers nowhere near the rate they are being diminished could lead to a rate of endangerment that wouldn’t be able to be reversed. Although at the rate that’s happening right now, it may be sooner than later. Multiple researches have come together at Planet Save to summarize the possible end result of sharks if tendencies were to keep up. With outnumbering death rates, and the huge boom in the market for shark fins, sharks could face extinction in a mere few decades. (Ayre 2). With over a dozen species already holding the label of endangerment, action needs to be taken now. Especially with such a small window for reproduction rates to pick up, they would need much more time than what they have now to get back to the point the rates were at almost two decades
Fishery Scientist are constantly working on ways to protect shark species and reduce shark bite incidences. Others have proposed that sonar waves are placed on nets to try and keep sharks away. Researchers are also collecting data from the sharks that are caught by the fishermen to be in a position to better understand sharks, and how we can live in unity with them. A shark tagging programme to try to better understand shark movements and patterns could also assist instead of culling. Statistics show us that there have been drastic reductions in fatal shark bites since nets have been installed in NSW and Qld.
Every year hundreds of sharks get killed just because people fear them. Western Australia has brought in the Shark Culls after a series of fatal attacks. Most of these people attacked are usually surfers, swimmers or shark haters. Now imagine this, what if you were a shark swimming and suddenly someone tries to hunt your down, how would you feel? We wouldn’t like it very much if the sharks did the same thing to us. In the following paragraphs, I would give you three reasons on why Shark Culling should be abolished not only in Western Australia but also all around the world.
As they are at the top of the food chain, sharks play a very important role in the oceans in a way that an average fish does not. Sharks keep populations of other fish healthy and in proper proportion for their ecosystem. By preying on the old, sick or slower fish in a population, they prevent the spread of disease and prevent outbreaks that could be devastating. According to Ransom Myers from Shark savers, “sharks may be gone within the next decades if we continue to kill them, resulting in the loss of important foods that we depend on for survival, causing a marine ecosystem imbalance.” At the same time, I accept that shark nets could be useful, especially in shark infested areas that have been renowned as spots where many attacks have occurred, but I still believe, as you would, that scientists should spend more resources on working out why it is becoming more common for sharks to be entering shallower waters, looking for food – namely seals, who just happen to look like
One of the governments main reasons for culling the sharks is because they are coming in too close to the shores and becoming a potential threat to swimmers. But why is this happening? This is due to a change in shark feeding habits, but because they are eating more human of course not! Rather because us humans are over fishing and eliminating the fish/food sources of which sharks normally feed on. This is forcing sharks to come in closer to find food. Us as humans have forced sharks to come in closer and are now killing sharks because of our a...
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
How many more fatal shark attacks will it take for someone in authority to acknowledge the damages, economically and socially, caused to human beings by sharks? We must legalise the culling of sharks. Sharks do not only brutally attack us humans but they also kill us. Culling sharks may not be the most pleasing way to find a solution but it is the most effective, quickest and easiest method. Scientists have argued that culling sharks will bring the ecosystem crashing down but this in fact is not true.

Sharks have been on this earth for nearly 450 billion years. To put that into perspective, the first modern humans date back to about 60,000 years ago ("Our Mission: To save Sharks and Mantas”). Since then, both humans and sharks have evolved into the predatory mammals they are today. However, with the quick development of humans, civilization and technology, humans have not been able to fully understand the ways of sharks, although the motives of other human celebrities have been easy to understand and decipher. Because shark attacks have been becoming more televised, and sharks have been known to be more of a “threat” to humans, shark research foundations, such as the Shark Research Institute and the Pelagic Shark Research Foundation, have been created to help give an understanding to these creatures. Over 100 million sharks are being killed each year, and there is a counter on the Bite-Back Shark and Marine Conservation website. As one spends more time on the home page, the number on the counter is constantly increasing, showing how many sharks are slaughtered in the year to come (“Bite-Back – Shark and Marine Conservation”). Even with research to show that sharks are valuable to the ocean and vulnerable, there are people that think otherwise (“The Pelagic Shark ...
Scientist are trying to find a way to keep the petrifying creators called sharks from harming their self’s and people. For instance, researcher found out magnets and electricity mess with these overgrown fish’s Ampullae of Lorenzini, which are special sense organs that assist with them finding their pray. Sharks are causing problems for humans and two ways to effectively solve this problem is with magnets and electricity.
Sharkwater is a documentary. Just like many documentaries it puts forth a strong message by using relevant facts and captivating footage. Sharkwater explores the nature of sharks, how misconception and ill treatment is driving them to the edge of extinction, and how some people are taking a step towards protecting them. The creator of this document did an excellent job went it came to using primary sources and proper facts. In some places of the world shark finning is a full-blown industry that is being protected by the government and was killing thousands of sharks everyday just for the sake of money. In that point of the film you could say a bias opinion was presented. But when the streets of Puerto Rico began to flood with angry protesters
Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
Every year, there are about 100 million Sharks killed, ultimately for its commercial success. Their fins are used as the main ingredient for a dish so-called Shark soup. However, many are unaware of the actual importance of Sharks' existence on Earth. They do a number of things to control and balance aquatic life down below, which in return affects how we live on the surface. Sharks have existed in our world for over 400 million years, if they were to suddenly disappear for industrial purposes, much problems will be encountered throughout the world. We must preserve the lives of Sharks, for many reasons most importantly that shark hunting is morally wrong, it may provide economic failure in a given time, and it may serve a critical unbalance of a healthy environmental state.
Shark slaughter is a cruel and violent act, to say the least. Granted that there is economical profit to be had from shark finning, the massive loss incomparably outweighs the profit. Most, if not, all humans would not enjoy having their limbs cut off and being left to die. It is simply inhumane and brutal. However sharks are experiencing this very thing, and the fact that they cannot express or protect themselves, is leading to the death of hundreds of millions of innocent sharks annually. Odds are that as you are reading this, a shark was killed. While sharks may not be the most adorable animals on the planet, they certainly are living creatures, and they feel pain just like us.
Back in the dynasty the Emperors would serve the dish to honor the guest, because they believed it had healing benefits from the concurring of a shark (Fairclough, Caty). Fin soup still occurs today even when not on special (Fairclough, Caty). In addition the shark fins for can sell for a pretty penny anywhere from $500 a pound or even $1,000 a kilogram (Fairclough, Caty). As a matter of fact, fishermen in Melbour, Segal would export $1300 pounds worth of shark fins a week. It was recorded that a single adult fin sells for $80 and a two-meter monster can sell for $300. Additionally, 1 out of every 100 sharks reported killed between 2000-2008 comes from these fisherman(Hinshaw, Drew). (commentary) about Its question that fisherman practice “unsustainable finning” because it does pay nice , but the amount of money gained by finning isn’t comparable to how much sharks are worth to our economy. The global value of shark finning is around $630 million but is declining, while shark tourism is worth $312 million and promises to be worth $780 million in 20 years ( source 8). Human activity of finning isn’t the only reason to the decline of Great White sharks, human protection is another
So if shark finning is such a horrible practice, then why does it still continue? The reason is quite simple: money. It 's mind boggling to see what people will do for a simple piece of paper, and shark finning is no exception. It is estimated that the fins of a shark can sell for up to $500 per pound! With these kind of profit margins, it 's no wonder that restaurants in China still sell shark fin soup.
