Sanctioned killings of sharks
Shark culling is the deliberate killing of sharks by government authorities, usually in response to one or more shark attacks. The term "shark control" is often used by governments when referring to culls. Shark culling has been criticized by environmentalists, conservationists and animal welfare advocates—they say killing sharks harms the marine ecosystem and is unethical. Government officials often cite public safety (attempting to reduce the risk of shark attacks) as a reason for culling. The impact of culling is also minor compared to bycatch with 50 million sharks caught each year by the commercial fishing industry.
Shark culling mainly occurs in four locations: New South Wales, Queensland, KwaZulu-Natal and Réunion.
Methods.
Shark nets.
Shark nets such as those used in New South Wales are designed to entangle and kill sharks and other animals that pass near them.
Christopher Neff, a Ph.D. scholar at the University of Sydney notes, "Internationally, shark nets have been labeled a 'key threatening process' for killing endangered species." He adds:" ... killing endangered species to boost public confidence or to show government action is not workable. It is a disservice to the public."
Drum lines.
A drum line is an unmanned aquatic trap used to lure and capture large sharks using baited hooks—some (such as those in Queensland) are designed to kill sharks.
Drum lines have been criticized for being environmentally destructive and speciesist, and have sparked public demonstrations and vocal opposition, particularly from environmentalists, animal welfare advocates and ocean activists. Conservationists say killing sharks on drum lines harms the marine ecosystem. In addition, Western Australia Fisheries Minister Dave Kelly said "there is currently no scientific evidence to show that drumlines reduce the risk of a [shark] attack". Shark experts and conservationists also say there is no evidence that drum lines prevent shark attacks.
Current shark culling locations.
New South Wales (Australia).
The government of New South Wales has a program that deliberately kills sharks using shark nets. They were first installed in 1935. The current net program in New South Wales has been described as being "extremely destructive" to marine life, including sharks. Between September 2017 and April 2018, more than 403 animals were killed in the nets in New South Wales, including 10 critically endangered grey nurse sharks, seven dolphins, seven green sea turtles and 14 great white sharks. Between 1950 and 2008, 352 tiger sharks and 577 great white sharks were killed in the nets in New South Wales. Also during this period, a total of 15,135 marine animals were killed in the nets, including whales, turtles, rays, dolphins, and dugongs. More than 5,000 marine turtles have been caught on the nets. Sixty-five percent of shark attacks in New South Wales occurred at netted beaches.
The current net program in New South Wales has been called "outdated and ineffective", and has been criticized by environmentalists, who say nets harm the marine ecosystem. They say there is no science showing that nets make the ocean safer for people. Humane Society International calls the nets a "knee-jerk reaction". The New South Wales government prohibits people from rescuing entangled animals—this prohibition has been called "heartless and cruel".
Following 11 shark attacks along the New South Wales north coast between 2014 and 2016, including two fatalities, shark nets and "smart" drum lines were deployed in December 2016 to cover five additional beaches along the New South Wales North Coast in a six-month trial. Five nets were deployed off Seven Mile Beach off Lennox Head; Sharpes, Shelly and Lighthouse beaches off Ballina; and Main Beach at Evans Head. No shark attacks occurred at the netted beaches during the trial, and the trial was continued for the 2017-18 summer.
In August 2018, it was announced that the nets in northern New South Wales would be removed, but that the nets in Sydney, Newcastle and Wollongong would stay. The New South Wales Green party said they wanted all lethal nets to be removed.
Queensland (Australia).
From 1962 to the present, the government of Queensland has targeted and killed sharks in large numbers by using drum lines and shark nets, under a "shark control" program—this program has also killed large numbers of other animals such as dolphins; it has also killed endangered hammerhead sharks. Queensland currently operates the largest shark culling program in Australia. In the first 11 months of 2013, 633 sharks were captured in Queensland—more than 95% of those sharks were killed. 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. From 2014 to 2015, 621 sharks were killed in Queensland. From 2017 to 2018, 218 sharks were killed, including 75 tiger sharks and 41 bull sharks; at least 64 sharks were shot and killed during this period. From 2001 to 2018, a total of 10,480 sharks were killed on lethal drum lines in Queensland. From 1962 to 2018, roughly 50,000 sharks were killed by Queensland authorities.
The following was said about Queensland's use of lethal drum lines:
"Lethal drum lines in Queensland are used to catch and kill sharks. They are set with baited hooks to ensnare these sharks, leaving them to die in agony. Those who don't die immediately on these lines are shot by a contractor who is employed by the Queensland Government."
Afd.org.au stated the following in 2015:
"[Data] reveals the ecological carnage of [Queensland's] shark control regime. 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. More than 84,000 marine animals have been ensnared by drum-lines and shark nets since the program began in 1962 [...] Nearly 27,000 marine mammals have been snared. The state's shark control policy has captured over 5,000 turtles, 1,014 dolphins, nearly 700 dugongs and 120 whales, all of which are federally protected marine species."
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.
Since the policy was implemented there has only been one recorded death, at Amity Point in January 2006. 21-year-old Sarah Kate Whiley was attacked by as many as three sharks in Rainbow Channel. The attack occurred in an unpatrolled area. 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". However, a 2014 poll indicated that 80% of Australians did not approve of shark culling in Australia.
The shark-killing program in Queensland has been criticized by environmentalists, conservationists, and animal welfare advocates—they say Queensland's shark-killing program is unethical and harms the marine ecosystem. Queensland's shark-killing program has been called "outdated, cruel and ineffective". The Australian Marine Conservation Society said, "the ecological cost of drum lines is high, with 97% of sharks caught since 2001 considered to be at some level of conservation risk."
In September 2018, the government of Queensland began culling sharks with drum lines in Cid Harbour in the Whitsunday Islands in response to two non-fatal shark attacks—six sharks (including five tiger sharks) were shot and killed, and their bodies were dumped at sea. The killings have been called a cull. Environmental groups criticized the cull; Shark Conservation Australia called the killings a "disgusting knee-jerk reaction" and said it was "a very shameful day here in Australia". The cull was also called a "farce". Jonathan Clark of the Sea Shepherd group said culling sharks would not make swimmers safer. "National Geographic" cameraman Andy Casagrande said the following about the cull: "When will basic intelligence and respect for the planet be a requirement for highly paid supposedly educated government officials?" Most Whitsunday locals resisted the cull.
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. 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.'"
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. This is not about public safety, rather it's a blatant tactic to reduce public scrutiny by a government under increased public pressure to end its archaic culling program."
KwaZulu-Natal (South Africa).
Shark nets and drum lines are utilised to kill sharks in a "shark control" program in KwaZulu-Natal, South Africa which has been occurring in KwaZulu-Natal since the 1950s. 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. 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 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. According to the KZNSB, "from 1940 until most of those beaches were first netted in the 1960s, there were 16 fatal attacks and 11 resulting in serious injury. In the three decades since nets were installed, there have been no fatal attacks at those beaches and only four resulting in serious injury."
In a 30-year period, more than 33,000 sharks have been killed in KwaZulu-Natal's shark-killing program. During the same 30-year period, 2,211 turtles, 8,448 rays, and 2,310 dolphins were killed. Although shark species such as the great white shark are protected in South Africa, the KwaZulu-Natal Sharks Board is allowed to kill these sharks (an exception was made for them). Shark nets are currently installed in Marine Protected Areas, and kill animals there. The current shark cull in KwaZulu-Natal has been criticized by environmentalists, and has been called "archaic" and "disastrous to the ecosystem". Shark Angels states, "It is hard to believe with all we know about sharks, including their dwindling numbers, their critical role in our oceans, and the small risk they actually pose to us, that the archaic process of killing these animals for bather “protection” still exists. But in KwaZulu-Natal, hundreds of harmless sharks - as well as turtles, dolphins and rays - still meet an untimely death every year as a result of the 28 kilometers of shark nets installed by KwaZulu-Natal Sharks Board (KZNSB)."
Réunion (France).
The prevalence of shark attacks at Réunion Island—there were 19 attacks between 2011 and 2016, including seven which were fatal—prompted Réunion island's government to carry out a range of systematic long term activities utilising "smart" drumlines and longlines. In 2013, 24 sharks were killed in Réunion. In the five years to August 2016, more than 170 sharks were killed as part of the cull. George H. Burgess called the killings "an archaic, knee-jerk reaction that seems more borne of vengeance than of science." Réunion authorities currently kill about 100 sharks per year.
Previous shark culling locations.
Dunedin (New Zealand).
Shark nets were installed in Dunedin, New Zealand for roughly 40 years, and were removed in 2011. The nets were found to be detrimental to the environment—700 non-target species were killed.
Hawaii.
From 1959 to 1976, a government-funded program killed 4,668 sharks in Hawaii. The program did not change the rate of shark attacks in the waters of Hawaii. Some Native Hawaiians are against shark culling because of the significance of sharks in Hawaiian culture (sharks are viewed as "aumakua", or personal-family gods).
Western Australia.
In 2014, a shark cull in Western Australia killed dozens of sharks (mostly tiger sharks) using drum lines, until it was canceled after public protests and a decision by the Western Australia EPA; from 2014 to 2017, there was an "imminent threat" policy in Western Australia in which sharks that "threatened" humans in the ocean were shot and killed. This "imminent threat" policy was criticized by Senator Rachel Siewert for killing endangered
