A study of killing of the sharks as a result of worldwide fear of sharks

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. Moving on the right direction, there has recently been a surge of laws to protect sharks. Dr Ryan Kempster also detailed the possible successes of chemical repellants, which have been used since the mid s "Some early testing revealed that the smell of rotten shark flesh appeared to be effective, presumably because the smell of rotten shark to a live shark may indicate danger and so the natural response is to flee," Dr Kempster said.

But McPhee said the Hawaii programme targeted a different species of shark and was therefore a poor comparison. In some eastern countries, shark fins are considered to be a delicacy and their cartilage is believed to have medicinal value. Chris Neff said earlier that this programme was the only one that could be compared to the WA shark cull because of the technical similarities.

However, the animal cruelty implications are not the only reason to stop this practice. Unlike most other fish, which have both bones and cartilage making up their skeletons, sharks have only a cartilage skeleton.

The finned sharks are often thrown back into the ocean alive, where they do not die peacefully: Eating shark meat exposes you to these potentially dangerous toxinsin particular, high levels of the methyl mercury.

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.

Sharks Turned Prey A fisherman holds a freshly cut dorsal fin from a scalloped hammerhead shark Sphyrna lewini. This is a problem because rampant overfishing is causing drastic worldwide declines in shark populations.

They include well-known species like the Blue Shark, Tiger Shark, Bull Shark, Oceanic Whitetip Shark, Blacktail Reef Shark, Houndshark and Hammerhead Shark, amongst others Advertisements The different shark species within these orders are extremely diverse in terms of their physical characteristics, distribution, diet and habits.

Will killing sharks save lives?

The Bull Shark is the most common predator for bathers as it frequents the same shallow waters in which the people usually choose to swim.

Responsible catch and release, use of circle hooks Get involved, tell your friends, write your congressional representatives.

Progress Around the world, people are realizing how critical sharks are to ecosystems and people, and officials are beginning to protect sharks on a variety of scales.

However, it is important that the animals as well as other fish, dolphins and turtles are able to swim over, under or around the nets if they are not to get tangled up in them and die, which is, sadly, what happens in some areas.

Some species, including the mammoth Whale Shark, swim through the waters with their mouths open, allowing plankton and other small creatures to enter through huge filters.

Some experts predict that if the killing continues at the current rate many species will be lost forever with potentially devastating implications for our ocean ecosystems. A variety of approaches may be the key to making progress in the future towards protecting sharks everywhere.

Some people support pdf increasing regulations on shark finning rather than banning it completely or using the whole shark so there is less waste and cruelty. The ocean ecosystem is made up of very intricate food webs. Of the 14 species of marine life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem.

As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes.Shark Control Programs result in the capture of a wide range of by-catch species including marine mammals, marine turtles, and sharks and rays not implicated in unprovoked attacks on humans.

• Information obtained from other shark control programs has documented that by-catch rates are often very high in the early years of a program.

In the "battle" between people and sharks, it's not even close. On average, around the world, humans kill some million sharks each year. And despite their fearsome reputation and often breathless media attention, sharks kill only about six people a.

Humans tend to feel scared of sharks first and then, at some later point, consider the actual risk that sharks pose (if the individuals consider this at all).

And this trend doesn't reverse over time. As a result, fishermen have a large incentive to gather and sell shark fins. Many fishermen prefer to practice shark finning instead of bringing whole sharks to the market because the fins are far more valuable than the rest of the body, sometimes selling for as much as $ a pound ($1, a kilogram).
