Recommended: Why should sharks be conserved
The future status of sharks is a concern for widespread conservation due to the decline of many species facing high levels of exploitation to meet market demands for products, especially fins.
The great hammerhead shark, Sphyrna lewini and s. mokarran s. zygaena, even in regions where management, substantial decline indicates that informed conservation measures are justified these distributed in kind occurs.
Despite the importance of evaluation of shark catches and trade on the basis of specific species for the possible exploitation of individual species, the achievement of this goal for sharks was difficult because the di ffi culties in identifying their products .
The development and implementation of multiple diagnostic test and polymerase chain reaction aerodynamic five-primer species specific primers based on nuclear ribosomal ITS2 three species of hammerhead shark throughout its global range.

Conservation measures for sharks reported planning require evaluation of their performance and the contribution rate of the single species hammer bring fin market. Here, we expand on the method Pank et al (2001) and Shivji et al (2002) and the report on the development and testing of a set of PCR primers specific species e ff ectively identify three species of hammerhead sharks, s. Hammerheads and s. zygaena s. mokarran
The Great Shark debate – to cull or not to cull, has been at the forefront of the minds of conservationists, as well as the general population for many decades now. The opinions of everyone are divided, according to their personal experiences, and views on what is right and wrong for the environment.
The bull shark may be responsible for many shark attacks in the world but I believe that we have no right to kill them. Sharks are very important to animals food cycles and if the food cycles get messed up it can greatly effect the world. In fact, the bull shark is more vulnerable to human impact due to their ability to live in fresh and salt water but many sharks that are killed are for either shark fin soup or their liver oil. The sharks liver oil has many uses now but it started as a machine lubricant. Another way that sharks die is by recreational fishing. The sharks can get caught up in the fishermen's nets and eventually suffocate and die. As an environmental community, I feel like we need to inform people about shark habits and how to keep sharks safe. The water is their home and we are
Information (sub-point): Shark finning also has also drastically negatively affected the entire shark population. According to SharkSavers.org, “Shark populations face the threat of extinction in every part of the world primarily due to overfishing driven by the high demand for shark fins” (SharkSavers, 2013). It is also found that the global shark population has decreased by a drastic 90% over the last 50 years, and if change does not occur quickly, the entire shark population could potentially disappear
Not only would one of the oldest living creatures on Earth become extinct, but humans would also be affected. Rob Stewart (Sharkwater’s filmmaker) and activist Paul Watson are leading the efforts to protect sharks. Because there are no international regulations to protect sharks, 1.5 million sharks were killed over the course of six days when long line fishing was legal in the Galapagos Islands. During the filming of the documentary, Stewart and Watson helped to make long line fishing in the Galapagos Islands

In addition to Western Australia’s targeted species being Great White sharks, Tiger Sharks and Bull Sharks, the QSCP contains a variety of additional target species, some of which have never been
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.
You are smelling the salty water around you and you suddenly feel something pass your leg.It`s a bull shark waiting to devour you.These species and the hammerhead are the two species of shark that you would not want to be noticed by.Both species are extremely dangerous and deadly.Bull and hammerhead sharks have many similarities and differences.The differences between these two species concerning apperance,diet,size and other important factors of the species` lives are important to know in case of close encounter and need of survival.It is important to know what they look like so it is easier to identify them and to know their special abilities so they will be easier to evade.Hammerhead sharks and bull sharks are very aggressive towards their prey and take over most oceans.These species are very important because if you want to study them for research,then you should know their normal personality traits for easier behavioral comparisons.
Shark slaughter has led to shark populations being rapidly decimated all around the globe. Fishermen report that sharks are also getting smaller because they are not being given enough time to fully mature. Although there are other fish that are targeted more than sharks, they are not exactly affected by the kind of endangerment that sharks are currently experiencin...
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
When most people hear the word "shark", the image of a vicious killing machine pops into their head. They picture something out of the movie Jaws, where a massive Great White shark terrorizes an entire beach and eats dozens of people. However, this fictional story is nothing more than Hollywood entertainment. In the real world, the tables are turned. Humans are the ones who kill sharks, and not just by the dozens. It has been estimated that over 100 million sharks are killed every year by humans (http://www.iflscience.com). Some estimates claim that the actual number of sharks killed every year could be as high as 273 million (http://www.iflscience.com). In this research paper, I will inform you of the many ways that sharks are being killed,
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the

Introduction One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus; it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans.
