PROS: Guaranteed to avoid a shark encounter by staying on land. The problem is that they float and dont connect with the shoreline or the surface, so its possible for sharks to swim over and under them. [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. Also, the removal of some animals creates more space and food for those left, leading to a higher rate of survival and reproduction. 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. 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. [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. Legal shark culling is mainly practiced in four locations: New South Wales (Australia), Queensland (Australia), KwaZulu-Natal (South Africa), and Reunion Waters (France). Environmentalists have proposed the banning of shark culling and the use of drum lines because they are threats to endangered species. But there has to be a plan in place to help achieve desired outcomes and mitigate the risks. They are literal nets that are designed to prevent sharks from getting near humans. These diseases can decimate large animal and human populations if not well handled. For example, bison are being culled in Yellowstone National Park. You might be thinking that culling sharks would decrease the risk of attack, however, thats not the case. These include electrical, magnetic, acoustic and spray repellents. [80] The NSW prawn trawling industry alone results in 64 tonnes of shark as bycatch each year,[64] with two thirds dying. Its a knee-jerk reactionpeople get bitten, people die, the government starts killing sharks. Marketed as 'eco friendly' having become artificial habitats for marine life. This helps to improve the overall genetic quality of the herd. Not only do the methods trap and harm other marine animals, but by removing large numbers of major predators, they create a knock-on effect that impacts all marine life. Intentionally reducing the number of sharks have more negative effects on the ocean than we can comprehend. The group of experts also add weight to other facets of the shark cull. A similar incident happened in New York in 1999 with the West Nile virus. Cape Cod voters, tourists and commercial fishermen are all likely to recognize sharks as an important, beneficial piece of the local marine ecosystem, but when it comes to seals, the groups have more divergent views, according to newly published data. '"[34], In October 2018, the Queensland state government proposed a policy which would ban the photography of shark culling in Queensland; Lawrence Chlebeck of Humane Society International said the following about this proposal: "The Queensland Government's plan to put exclusion zones around shark control equipment is simply a measure to keep the slaughter of sharks and marine wildlife hidden from public view. PROS: Provide a complete barrier between swimmers and sharks. Lifetime cow studies were conducted at a USDA experiment station in Montana. Professor Colin Buxton of the University of Tasmania told the ABC: "the use of shark nets and drum lines is a proven way of reducing shark attack, however the public need to understand and acknowledge that this works by killing sharks". Sure, sharks are dangerous and if they get you in their sights, they can destroy you in an instant. This should serve as a warning to those culling elephants. Acoustic tagging is the primary method used to tag white sharks in Australia. Bottom Line "[15], Jane Williamson, an associate professor in marine ecology at Macquarie University, says "There is no scientific support for the concept that culling sharks in a particular area will lead to a decrease in shark attacks and increase ocean safety. There are several creatures, as small as microscopic infectious viruses to as big as hippopotamuses, that had befallen death on our loved one. Will smart drum lines actually prevent shark attacks? They have been trialled in Western Australia. There is also the financial cost of installation and personnel to monitor the nets for bycatch. This makes sense, because sharks are mindless killing machines, and will take anyone's life if they get a chance. Shark culling or "shark control" is the act of deliberately killing sharks, thus reducing their population sizes, and preventing shark attacks. A range of commercial products that claim to deter sharks from humans are available. CONS: Further testing needed, including to see if large fish and non-target marine life are picked up by the buoys. On the surface it makes sense that few sharks in the water would result in fewer bites on human. To add to the insult, all of the victims were from near-threatened tiger shark species instead of the targeted great white shark. You would have to kill a lot of sharks to create the level of depletion needed to result in a measurable drop in the risk to humans". These large species of animals have low reproduction rates and take very long to mature. The price of shark culling is too high with other marine life getting caught on the lines 4. Culling offers many potential benefits, as highlighted below. The rationale for culling was a widely-held belief that tiger sharks were site-attached . Among the advocates was the world-renowned surf champion and climate activist, Kelly Slater. In case of an outbreak of HPAI, one way of controlling the spread of the disease is through the culling of infected poultry. If another way of controlling animal populations is not developed, very soon, many species might be wiped off the face of the earth. In spite of such efforts no significant decrease in .

But contrary to what you might think, shark attacks are incredibly rare. It is a disservice to the public. A drum line consists of a large, baited hook suspended from a large plastic float, which in turn is anchored to the sea bed. Natalie Banks, testified the statement saying that the use of shark hooks has never proven to work. 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. Every year, thousands of seals are hunted down and killed as a way of controlling their population. The same happens in North America, where tourists pay as much as 500 dollars to hunt White-tail deer. Protecting humans from sharks: What are the options?

Top on this list of pros and cons of culling animals are the economic benefits from culling. 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. Every animal entangled suffers when shark culling, Australia-wide. Sharks regulate the behaviour of prey species, and prevent them from over-grazing vital habitats. [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. The feces would also contaminate waterways leading to the risk of diseases. In Hawaii, sharks were culled during the 1960s and '70s with no reduction in bites; recent tagging research implicates habitat preference as the primary driver of shark density, with new sharks moving into preferred areas upon the elimination of other sharks. [49], From 1959 to 1976, a government-funded program killed 4,668 sharks in Hawaii. 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. Follow the action from the third Test between India and Australia in Delhi in our live blog, Former government services minister Stuart Robert is being questioned at theRobodebt inquiry. As a result of many insectivorous bats, which help to reduce crop pests, have been killed in the process. [19], The government of Queensland currently kills sharks in the Great Barrier Reef using 173 lethal drum lines; in 2018, Humane Society International filed a lawsuit (court challenge) requesting that the drum lines be removed there. If a shark is sighted in the area leave the water as quickly and calmly as possible. Those in opposition argue on the lack of scientific evidence for the approachs efficiency and moral grounds. Fact Check: Are smart drum lines just a PR exercise? "[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.

Instead, other marine animals like seals, turtles and dolphins can get caught on the hooks, resulting in their death or serious injury. [12][42] The region's shark attack statistics primarily reflect the effectiveness of netting, as drum lines were only introduced recently, following their successful use for over 40 years in Queensland, Australia. Sharks are more use alive than dead This is a difficult time. In Northern Australia, tourists are offered an opportunity to hunt crocodiles that have been earmarked for culling. So culling only hastens the process of extinction. What Is The Purpose Of Shark Culling? The attack occurred in an unpatrolled area. 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. They help regulate the population and distribution of the species below them in the food chain, thus maintaining the diversity undersea. "[74] Kelly Wang of One Green Planet said, "Australia's attitude towards its sharks is truly horrific. More about how we earn money as an affiliate. A range of brightly coloured and striped wetsuits are currently being marketed as shark deterring outfits. Well, heres a detailed list of all the benefits and drawbacks that come with this practice.
