In the eyes of society and the public, sharks are viewed as ruthless killers Millions upon millions are killed every year, and fear is a major contributor. The reality is that sharks are very complex creatures, and should be treated as such. They are an intricate part of the ocean’s ecosystem and the ecosystem would be completely thrown off without them. We need to realize that these creatures are invaluable, and that we must conserve these animals. If we do not realize this reality, we could lose sharks forever.
There is a huge problem with finning for shark steaks or shark fin soup. Because of this, some shark species have dropped by 90 to 50 percent (Choi). In the 80s commercial fisheries made the population of sharks go down even further. Approximately 20 to 100 million sharks are killed each year due to fishing (lovgren). This has caused the total shark population to drop 30 to 50 percent
Did you know that zebra mussels cost the economy 5 billion dollars a year? 5 billion!? The zebra mussels are an invasive species that came from Europe to the states. They attached to boats and traveled there. Zebra mussels are a big problem because they cost the economy lots of money, eat up almost all of the plankton, and they hurt aquatic life.
Sharks, dolphins, turtles, seals and seabirds all get tangled in these nets, as by-catch, with no way to get out. Some of the animals that are caught die, either while they’re being dragged along the bottom of the ocean or when the fishermen bring them on deck and don’t put them back fast enough. FAO experts assessment concluded that there are roughly 27 million tonnes of global by-catch for every 77 million tonne catch. This statistic means almost 1/3 of every catch is by-catch. Fish populations are on the decline, no thanks to carless fishermen and their pollution.
These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors. The impact of overfishing on shark populations has risen into the public eye over the recent years due to several documentaries and movies that have been released recently. Sharks are particularly vulnerable to over-exploitation due to their K-selected life strategy, having slow growth rates, long life spans and due to them reaching sexual maturity at relatively late age compared to that of other marine organisms (Stevens et al., 2000). Fisherman fish for sharks in order to get their fins, which is used to make shark fin soup (a delicacy in South-East Asia).
Fishery Management: RBM and Fishery Subsidy Over fishing around the globe has lead to a dire need in effective fishery management as it has led to fisheries depleting worldwide. Seafood is one of the more popular delicacies around the world and is also the source of income for millions of fishers globally. Lack of and poor fishery management has led to an exhaust of the fish stock in the ocean, which in turn has had a negative impact on biodiversity. Poor management has also been a factor economically as it leads to a loss of about $50 billion annually for fisheries around the world. If proper steps are taken the problem can be managed, Fishery Solutions Center believes that if management is improved then abundance of fish can increase by
Annual tolls because of sharks are much less than deaths resulted in meetings with crocodiles, tigers or elephants. Last two representatives of the huge terrestrial fauna kill around 100 people each year, while sharks have around five victims on their account. Meanwhile, tigers and elephants already had law protection, when the documentary was created, while sharks were treated as a source of valuable product (their fins) and a monster that should be killed before it would get an opportunity to attack. Numbers, mentioned by the film, created the impression the situation is totally unfair. As if officials today will forget about their efforts against the ivory black-market
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”.
Hunting in the 1900s by people hungry for whale oil drove the species toward extinction. More than 360,000 whale were killed during this period. In 1966 Blue Whales became protected with the International Whaling Commission, still their recovery has been minor. Nevertheless, Humpback Whales have not been effected to this extent. The Humpback Whale population has recovered since its stint on the endangered species list in the 1970s.
Offshore Drilling Every year, in the United States alone, 565 million barrels or oil are extracted as a result of offshore drilling; totaling a startling amount of roughly 1.5 million barrels a day. Consequently, these threatening practices are negatively impacting marine mammals, sea birds, sea turtles, and fish. Although drilling offshore provides access to expensive resources such as oil, it heavily contributes to the extinction and endangerment of animals, and the disruption of marine ecosystems, thus these practices should be prohibited and viewed as unethical. To begin, new techniques of horizontal drilling allow for even greater amounts of oil to be extracted from a single well, producing problems in infrastructure on land. Despite this issue being seemingly unrelated to wildlife, it is a detrimental issue placing animals in turmoil.
marine animal I’m researching is The Great White Shark. They are also known as, White Death and White Pointer. Great White Sharks are located off the coast of California, Australia, South Africa and the northern United States. Other continents and countries call them Tommy Sharks, Blue Pointer, Uptail, Maneater, etc. Great White Sharks are mostly infested in the USA and Australia and have caused 188 deaths in total.
