[1], In Recife, Brazil, the number of shark attacks was reduced by 97% when long lines and drum lines were deployedin the Recife program, some of the sharks were caught on drum lines and then moved away from the shoreline. What are the pros and cons of culling animals? [4] The "imminent threat" policy was canceled in March 2017. In New Zealand, for example, after WWI, the emus had multiplied so fast that they were a danger to farmers. Dr Daniel Bucher from Southern Cross University told the ABC: "Great whites are a threatened species and the existing population is already low. The RSPCA does not support killing sharks as a response to shark incidents involving humans. The WA Fisheries minister highlighted the need to concentrate and invest in new and emerging technologies that offer real protection for the people who are most at risk, i.e., surfers and swimmers. The giant nets are also problematic because other small creatures get trapped and are then killed. [12] The current shark cull in KwaZulu-Natal has been criticized by environmentalists, and has been called "archaic" and "disastrous to the ecosystem". [31] From 2001 to 2018, a total of 10,480 sharks were killed on lethal drum lines in Queensland. You can be a voice for sharks and other marine life by signing the petition to end 84 years of shark culling, remove the nets and drum lines and opt for more non-lethal alternatives to shark mitigation. The shark population has, d significantly in the number over the past few decades in Australia. Shark culling or "shark control" is the act of deliberately killing sharks, thus reducing their population sizes, and preventing shark attacks. From 1959 to 1976, the state of Hawaii culled 4,668 sharks (at an average cost of $182 per shark), including 554 tiger sharks, in a series of shark control programs. CONS: Associate Professor Adam Stow, of Macquarie University told the ABC that: "Killing sharks risks disruption to the ecology of the ocean". [16] Humane Society International calls the nets a "knee-jerk reaction". [22] Jessica Morris of Humane Society International calls shark culling a "knee-jerk reaction" and says, "sharks are top order predators that play an important role in the functioning of marine ecosystems. When bats are culled in South America to prevent rabies, for example, care must be taken to remove overabundant vampire bats, rather than insectivorous bats that typically do not interact with.

There is also the financial cost of installation and personnel to monitor the nets for bycatch. "Shark culling is a relic of the past. [22][21][11][39][40][70][71][72][73], The Sea Shepherd group said, "Politicians responsible for the shark cull policy have displayed an unwillingness to explore other shark mitigation strategies". [51], The impact of shark culling is minor compared to bycatch from commercial fishing. What Is The Purpose Of Shark Culling? Sharks regulate the behaviour of prey species, and prevent them from over-grazing vital habitats. Both domestic and wild animals can contract diseases when they come into contact with bacteria in soil, plants, or water. For example, between 1967 and 1994, South Africa culled a total of 14,562 elephants. Because were looking at the pros and cons of culling animals, it is important to address the question; is calling animals bad? [11][12][13][14], Carl Meyer, a researcher at the Hawaii Institute of Marine Biology, calls the disagreements about shark culling a "philosophical" debate, about "whether it is ethical to kill large predators in order to make the natural environment a safer playground for humans. [62], Environmentalists, conservationists, scientists, animal rights activists and shark experts oppose shark culling. They confuse humans for defenseless animals (which, arguably, we are in the eyes of a shark), and most of the time, they dont really care what were doing. China has taken a 'dramatic' lead in critical technologies used for military power, report says, Former minister takes 'absolute responsibility' for Robodebt, admits defending scheme despite knowing it could be unlawful, Aussies collapse in dramatic fashion to be all out for 197, MP Monique Ryan and chief of staff Sally Rugg fail to settle dispute after four-week mediation, 'Sickening, callous and brazen': Sydney man dies in hail of bullets in front of 12yo son, Evelyn worked three jobs when she was in her 20s to build up her super. Here, culling is done based on factors affecting cow performance, such as milk production, reproductive status, and diseases. The Grom Life is an independent publisher. Of these animals, 7 were dolphins, 7 were green sea turtles, and 10 were grey nurse sharks, which are critically endangered. The use of nets and baited drum lines is an outdated and ineffective approach against shark attacks. One of the solutions focused on the culling of four pests that were carriers of this disease; rats, sparrows, flies, and mosquitoes. Many tourists are willing to pay thousands of dollars to go on hunting expeditions aimed at culling animals. Sharks: they're some of the most majestic and wondrous animals in the ocean. In total, more than 8,000 marine species with some level of protection status have been caught by the Queensland Shark Control Program, including 719 loggerhead turtles, 442 manta rays and 33 critically endangered hawksbill turtles. The program is based largely on claims by the WA government that the cull will a) increase ocean safety, b) not. In Australia, white sharks had caused several human fatalities. As a result, the government started culling them. [32] It has been argued that killing sharks in the Great Barrier Reef is "vastly inconsistent with the Great Barrier Reef Marine Park Authority's main objective, 'to provide for the long-term protection and conservation of the environment. [80] Australia's commercial shark fishing industry catches over 1200 tonnes of shark each year,[64] 130 of which being great white sharks. 21-year-old Sarah Kate Whiley was attacked by as many as three sharks in Rainbow Channel. Sharks are so crucial for the, A marine biologist from the School of BioSciences, University of Melbourne, Robert Day, says, the top predators of the trophic levels in any ecosystem are critical because they, decide on whether other species thrive or not, Sharks prey on old, diseased, or weak creatures, thus maintaining the, If the number of sharks in the ocean declines, then other predatory fish species will become abundant that. PROS: Provide a complete barrier between swimmers and sharks. They set up traps to catch and kill the cats. [81] Tuna and swordfish longline fishing off the coast of South Africa reported 39,000 to 43,000 sharks killed each year between 1995 and 2005. Culling also helps to manage animals without natural predators. Will smart drum lines actually prevent shark attacks? "[34], "[Data] reveals the ecological carnage of [Queensland's] shark control regime. PROS: Statistics support their efficacy, with one fatality at a netted beach between Newcastle and Wollongong in the past 70 years and an overall drop in shark interactions with humans since nets were installed around Sydney and Queensland. [2][3][4][5][6][40][68] They say sharks are important to the marine ecosystem and that killing them harms the marine ecosystem. Sparrows helped to regulate the population of locusts and other insect pests in rural China. Below are five reasons why the practice is not 100% foolproof. This means they have to be culled. So instead of becoming the solution, culling compounds the problem. [49], From 1959 to 1976, a government-funded program killed 4,668 sharks in Hawaii. CONS: Contractor required to check drumlines and relocate the sharks, contractor needs to reach the caught shark in a timely manner, other marine life may be caught. During that period, about 114 sharks and other animals died. Instead, other marine animals like seals, turtles and dolphins can get caught on the hooks, resulting in their death or serious injury. "[17], A drum line is an unmanned aquatic trap used to lure and capture large sharks using baited hookssome (such as those in Queensland) are designed to kill sharks. Environmental Protection Authority of Western Australia, the French Overseas Department of Runion, "Can governments protect people from killer sharks? This makes sense, because sharks are mindless killing machines, and will take anyone's life if they get a chance. Shark culling and shark hunts, as an acceptable. These diseases are highly infectious and fatal for both animals and humans. has been looking into available options to minimize the risk of shark attacks. The efficiency of the shark nets and drum lines as deterrents is also questionable. Sharks have gained an identity of the vengeful. [47] George H. Burgess called the killings "an archaic, knee-jerk reaction that seems more borne of vengeance than of science. As northern New South Wales residents continue to debate the best way to deal with shark attacks in the region, we take a look at the pros and cons of the most popular options available to protect people from ocean predators. Bottom Line Mr Barnett says commercial fishermen . The culling of ferrets led to a doubling of their population. These diseases can decimate large animal and human populations if not well handled. Shark nets are also used in New South Wales, which includes major cities like Sydney and Canberra. The Premier says such behaviour has damaged the standing of the environmental movement. Shark sightings and reports from the public as well as from government and emergency services are recorded, with alerts sent out to user's smart phones and via social media. [36] Queensland Fisheries Minister John McVeigh has described the longevity of the netting and drum line program as being "a good indicator that it had the support of most Queenslanders". For an ocean with sharks is a healthy ocean and one that stands a greater chance in mitigating against the climate emergency we are in. Unfortunately, instead of the yields increasing, they went down, causing greater losses. The nets are submerged near high-population areas and are designed to trap, entangle, and kill the shark. Demonstrable effectiveness means a measurable decrease in shark bite incidents in response to culling activities. One of the best examples of this took place in China. Those in opposition argue on the lack of scientific evidence for the approachs efficiency and moral grounds. Maybe we should have a cull on mattress stores. The same happens in North America, where tourists pay as much as 500 dollars to hunt White-tail deer. First introduced in the 1930s at a time when we didn't know much about biodiversity, shark behaviour or sharks' vital role in ocean ecosystems. Shark culling is a term used to describe the blatant killing of sharks and is also used by some to describe the use of traditional drumlines. About half of the shark species caught in Queensland's nets and drumlines pose very little risk to humans. Five nets were deployed off Seven Mile Beach off Lennox Head; Sharpes, Shelly and Lighthouse beaches off Ballina; and Main Beach at Evans Head. "[46] Runion authorities currently kill about 100 sharks per year. Cant we co-exist peacefully using appropriate measures that keep us safe and sharks alive? Pollution Types, Shark Nets trap other small creatures as turtles (via Unsplash), The ocean plays an integral role in sustaining our environment and climate, so do sharks and every other creature that lives below the surface. Given the legal status sharks enjoy, the benefits to humans would have to be especially high to justify culling as an ethical option. Below are the 10 important pros and cons of culling animals. Films like Jaws have given everyone the false impression that sharks are out there waiting for humans to bob by so they can snap and feast. CONS: Can not be everywhere at once, possible visibility issues when water clarity is not ideal, financial cost of hiring aircraft and/or personnel to conduct surveillance, water-users may ignore warnings. [18] Shark experts and conservationists also say there is no evidence that drum lines prevent shark attacks. [32] From 1962 to 2018, roughly 50,000 sharks were killed by Queensland authorities.[33]. Unfortunately, our government authorities aren't marine ecology experts and don't always understand the impacts of such a decision. It is estimated that up to 100 million sharks are caught globally each year. In the three decades since nets were installed, there have been no fatal attacks at those beaches and only four resulting in serious injury. . [51] A non-lethal Shark Spotters program in Cape Town, South Africa has been in use since 2006. Before we take a closer look at shark culling, lets address the prevalence of shark attacks. Billions of them were killed. However, there are times when the culling of animals is driven by public hysteria and arbitrary reasons. But contrary to what you might think, shark attacks are incredibly rare. This shows that the benefits of shark tourism have a cascading effect on the entire ecosystem. PROS: Ability to sight sharks from the air and potentially give warning to water-goers through the use of sirens or signals. What do the Public Think About Culling Sharks? [11] More than 5,000 marine turtles have been caught on the nets. To put that into perspective, jellyfish kill 40 people a year and in the United States alone, over 400 people die from falling out of bed. And what effect do they have on the marine environment? Eventually, the state government decided to cull them, which solved the problem. Valerie Taylor is a competitive spear fisher turned shark conservationist who is adamantly opposed to shark culling and the methods used. So culling only hastens the process of extinction. But be aware of their limitations many devices haven't undergone independent testing, and no device will protect you in all circumstances". There was no difference in number of shark attacks on humans recorded in the Hawaiian islands during the time the program was active or immediately after the closing of the program. He adds:" killing endangered species to boost public confidence or to show government action is not workable. Any contact with animals should always be humane. "[35], About 360 baited drum lines have been placed off the coast of Queensland, including 78 along the Sunshine Coast, 54 near Townsville, 27 near Mackay and 38 near Cairns. [54] This "imminent threat" policy was criticized by Senator Rachel Siewert for killing endangered sharks. Shark culling or shark control is the act of deliberately killing sharks, thus reducing their population sizes, and preventing shark attacks. PROS: Guaranteed to avoid a shark encounter by staying on land. Removal of large ocean predators causes a meltdown in the delicate oceanic ecosystem that influences the carbon emissions, and thats exactly whats happening in Australia, said Dr Peter Macreadie, co-author of the paper. "Sharks keep oceans and reefs healthy," Banks said. [59] Organisations that support shark control programmes include the Queensland State Government,[41] NSW State Government,[1] Surfing Australia,[60] Surfing NSW,[61] Surf Life Saving Queensland,[62] several politicians within the Liberal National Party of Queensland,[41] the French Overseas Department of Runion,[63] and the KwaZulu-Natal Sharks Board. [21], There are also reports of shark attack survivors being harassed and abused on social media, presumably by extreme environmentalists. The KwaZulu-Natal Sharks Board (KZNSB) says, "Both types of equipment function by reducing shark numbers in the vicinity of protected beaches, thereby lowering the probability of encounters between sharks and people at those beaches." The decision was condemned by the environmentalist, conservationist, and native Australians alike, with. Also during this period, a total of 15,135 marine animals were killed in the nets, including whales, turtles, rays, dolphins, and dugongs. Overfishing, shark finning, climate change, black market trade, and habitat loss have had a massive effect on sharks. [1] "From 1900 to 1937, 13 people were killed off New South Wales surf beaches by sharks; over the next 72 years, the death rate fell to eight, only one of which was at a meshed beach. Furthermore, theres a massive potential to offset carbon emissions by maintaining aquatic ecosystems and seagrass. Natalie Banks, testified the statement saying that the use of shark hooks has never proven to work. Acoustic pulses from tags are detected by underwater receivers also known as listening stations but sharks need to swim close (typically within 500 metres) to a listening station for its acoustic tag to be detected. Put simply, shark culling is a deliberate government action to kill and reduce the numbers of sharks in our oceans, which is usually an unthoughtful, knee-jerk reaction to a shark attack. Without sparrows, the locusts and pests destroyed a lot of grain, contributing to the Great Famine of China that killed millions of people. [1] From 2013 to 2014, 667 sharks were killed on Queensland's drum lines and in shark nets, including great white sharks and critically endangered grey nurse sharks. As stated earlier, culling should be based on solid facts and a well-thought-out plan of action. The KZNSB also states that there were seven fatal attacks at Durban from 1943 until the installation of shark nets in 1952, and that no fatalities or incidents resulting in serious injury have occurred since nets were installed. Black wetsuits have been criticised by some for making swimmers and surfers look like seals. Those with undesirable traits are culled, allowing farmers to drive profitability. Great Whites are an endangered species and therefore enjoy legal protection. the effectiveness of SMART drumlines were in question, Is Deep Blue The Largest Great White Shark, Sharks and Surfers: Risks, Tips, and More, Yum Yum Yellow, Surfing, Surfboards & Sharks, The Best Surfing Movies From The 80s, 90s & 2000s. Posted on Last updated: November 18, 2022. Just as we cannot scare our kids that they cannot go in the water or theyll get chopped in half, we dont have control over the oceans; thats their home. Read the full story at: http://ab.co/19EtXgZ. From 1959 to 1976, the state of Hawaii culled 4,668 sharks (at an average cost of $182 per shark), including 554 tiger sharks, in a series of shark control programs. Not only are shark attacks still common at beaches that have shark nets installed, and not only do they lead to a slow and painful death for the shark, but they kill other marine life as well.
