GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet.
According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly. Sharks rely on their fins to swim and allow water to

I have swum with Caribbean reef sharks in the Bahamas and have seen how beautiful and strong they truly are first hand. Sharks are a vital part to every ecosystem they are in and currently being killed at a rate that they cannot reproduce at. Alpha predators are a necessary component of eco-systems because they keep the populations of every trophic level below them in check. You can compare an eco-system to a skyscraper; you need every single part so the entire building does not fall apart. Sharks have the task of killing the wounded, old, and sick fish in schools to keep the stocks of fish healthy and plentiful. Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth. Most sharks only have one or two pups every time they give birth. These factors make the time-period
The hammerheads have an unusual behavior of forming schools that can have as many as 500 sharks. They stay together in the daytime and separate at night. This practice provides protection against larger predators. Hammerheads do not have mates for life. The female gestational period is 12 to 18 months and they can produce 10 to 17 offspring at a time!
Hammerhead sharks are carnivore because they eat meat much as fish species. They will eat fish to regain their energy because they use most of it swimming. They also use energy by using their sense of smell that allows them to detect blood. When a shark reaches a point when they can’t use any more energy, they will go deep into the ocean and stay there. Their preys won’t spot them as easily when they are deep in the ocean.
These three sharks appeared from 190-95 million years ago. They were the first offshore-deepwater predators. Before that, most shark were small, near shore predators, who lived in very shallow waters. Then during the Tertiary Period, which was 65-35 million years ago, the so-called “filter-feeders” came along. These are the types of sharks who evolved away from being predators, and fed on plankton and other small marine
To conclude, the ocean is ultimately the sharks home and it has been for millions of years and we are intruding on it though all of the point brought forward you can clearly see that rouge sharks should be let go sharks kill barley any people compared to a lot of others, they don’t go out of their way to eat humans and the general public is convinced by the media that sharks are evil man eaters this leads me to believe that sharks should be let be evacuate the beach and let the shark move on, once the shark has moved on think of shark prevention tactics such as nets, shark shields, extra patrols
The bull shark (Carcharhinus leucas) or also named Zambezi shark. The bull shark starts its life when its mother gives birth to about one and thirteen per liter. The mothers give birth around between late spring and early summer. When mating the male nips at the back of the female and grasps one of her pectoral fins in his mouth, this usually leaves a scar for the female called courtship scars. They are immediately on their own and separate from each other.
A shark net is a submerged net placed around beaches to reduce sharks attacks. on swimmers It does not always stop shark attacks, but it does help reduce them. A shark net is normally about 6m tall and 200m wide and floats below the surface of the water. They stop and capture the sharks in the net. I believe that we should use shark nets more, because it keeps people safe and also keeps the sharks away from the swimming beaches.
Over time, the rate in which they reproduce decline because they didn't have worry about their offspring being able to survive. Compare to a rabbit who is at the bottom of the food chain, they have to reproduce quickly in order for some of their offspring to survive to maturity. For the great white sharks, the gestation period takes around 12 to 18 months. Great white sharks are ovoviviparous, which means they produce their babies in eggs than the eggs are hatched within the body. It is an estimate that a great white shark is able to produce two to ten pups.
Provided that sharks have not been fished out of certain areas it is reasonable to assume that their disappearance would be a result of the destruction of a suitable habitat. The fact that shark species are so diverse and inhabit every ocean on the planet makes them key players essential to the ocean environment. Yet despite their importance in the marine food-chain they remain a low conservation priority. For all their evolutionary success and apparent menace, sharks are incredibly fragile, unable to withstand the increased pressures forced on them by the voracious world fishing industries. This is partly due to the fact that sharks are slow growing animals that mature late, live long, and have a low reproduction
Although sharks are dangerous, they only kill for food. They bite their prey from below taking only 1 bite and leave them for dead. When attacking prey, since they have no eyelids, they roll their eyes into their sockets whites biting (Hammond 15). Sharks are not picky eaters and use their ability to swim up to 35 miles per hour (“Great Animal”) to catch large animals such as sea lions, tuna, other sharks (Socher 376), small toothed whales, and sea turtles (“Great National”). Considering how sharks truly are not picky whatsoever no one would doubt that they ate some crazy things including license plates, paper cups, reindeer antlers, or anything else they find that humans have left or dropped in the ocean (Candelaria 9).
Jake/lamb 7-8/ Mrs. Peeper Shark Information Paper Qualities of Sharks Hammerhead shark or blue sharks could save your life one day!!.These species have unique characteristics that could hold the cure for human diseases. Other benefits are, they keep our oceans clean and they could help us discover the origins of our past. Hammerhead sharks are very unique and here some characteristics about them. Hammerhead sharks are found in ecosystems in temperate and tropical oceans.
These predators will eat fish, dolphins, turtles, birds, and other sharks. Bull sharks have a specific technique when they stalk. It is called the bump and bite method, and begins with the shark bumping its prey to disorientate and/or kill. They will then impale its lower jaw into its target, and then swing its head side-to-side with its upper jaw to take tissue from its victim(sharks.org). Sometimes, the sharks will hunt in groups.
Human beings can be attacked by sharks. Most shark attacks are caused by particular shark species. They include Carcharodon carcharias, Galeocerdo cuvier, and the Carcharhinus leucas. Historically, shark attacks are on the decline following increased global awareness on the menace. Shark attacks are most common in the United States waters than the rest of the world because of difference in climatic
In the article about the shark attack in South Africa by ESPN, the article talks about surfing professional Mick Fanning’s unbelievable escape from a great white shark attack. Mick Fanning and Julian Wilson were competing in the J-Bay Open in Jeffrey’s Bay in South Africa. As the men were swimming out into the bay on their surf boards Fanning’s board was attacked by the great white shark. The shark grabbed the cord by Fanning’s ankle. Fanning was dragged off the board and into the water, but he kicked, punched and screamed at the shark and took his ankle cord off.
The movie “Jaws” is actually why a great number of people are afraid of sharks. This movie has also greatly impacted great white sharks and their numbers. The movie created this false notion that great white sharks were human-killers that wanted nothing more than to eat humans. Because of this false notion there was a lot of hatred formed and lots of fisherman were targeting the great whites. There was even “shark tournaments”.
What is shark finning you inquire? Shark finning is the evacuation of a shark 's balance then the remaining parts being tossed over the edge alive. The shark is frequently still alive when it is tossed into the water, finless. They can 't swim without balances thus they will sink to the sea depths to be eaten alive by other fish. Finning of sharks happens adrift as it is just the blades they require, shark meat is a low esteem and is unneeded.
