They are used throughout Western Australia where they are typically fixed at a depth of about 6 meters and run just under 200 meters long. How could they think that when shark attacks are becoming more and more common? [41] 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? In fact, when shark culling was carried out in Hawaii, between 1959 to 1976, over 4,500 sharks were killed and yet there was no significant decrease in the number of shark bites recorded. On the surface it makes sense that few sharks in the water would result in fewer bites on human. Sure, sharks are dangerous and if they get you in their sights, they can destroy you in an instant. [39][41] 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". In 1949, diseases were ravaging and killing hundreds of Chinese. Sharks have gained an identity of the vengeful. However, sometimes they do not distinguish between the different types of bats. They are killed to protect surfers, swimmers and other people engaging in ocean water activities. 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. . A Brief Look at Shark Culling. The tags are attached to a small arrow-head and a short tether and are usually attached to sharks using a tag pole as they swim past a vessel. The emergence of HPAI was also attributed to Asian poultry flocks. Unfortunately, our government authorities aren't marine ecology experts and don't always understand the impacts of such a decision. 21-year-old Sarah Kate Whiley was attacked by as many as three sharks in Rainbow Channel. [18][27] The New South Wales Green party said they wanted all lethal nets to be removed. Use of colored and striped swimwear and equipment. The group of experts also add weight to other facets of the shark cull. "[1][65] A more recent analysis highlighted that there were three shark attacks, none fatal, at KwaZulu-Natal's "controlled" beaches between 1990 and 2011, while at unprotected beaches nearby there were 20 fatal attacks in the same period. That list can include any act that further endangers already threatened species, or adversely affects two or more listed threatened species. The traps with a baited hook that are used to attract and snare sharks instead trap them on the ocean floor, leaving them unable to swim. 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. However, it was later discovered that the major transmitters of the virus were daytime mosquitos, meaning they had been killing the wrong species. Shark culling or shark control is the act of deliberately killing sharks, thus reducing their population sizes, and preventing shark attacks. However, there are times when the culling of animals is driven by public hysteria and arbitrary reasons. CONS: Traditional drumlines are designed to kill sharks. We should always establish both the pros and cons of culling animals before imposing any culling measures on any species. Any contact with animals should always be humane.

Top on this list of pros and cons of culling animals are the economic benefits from culling. 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. The feral cats of Tasmania are a case in point. Shark-spotting programs using surveillance techniques, including drones, private helicopters, observation towers and even blimps, are being trialled in various locations across the globe. But even then, unintended consequences can arise, which affects biodiversity. Great Whites are an endangered species and therefore enjoy legal protection. But there has to be a plan in place to help achieve desired outcomes and mitigate the risks. At first, things went well, and the population of feral cats started going down. The 199798 outbreak of the Nipah virus in Malaysia, for example, claimed the lives of over a hundred pig farmers.

According to a spokesperson for WA's Fisheries Minister Ken Baston, in September 2014 the WA Government withdrew its proposal for the operation of drum lines for a further three years because the WA Environmental Protection Authority found there to be a: "high degree of scientific uncertainty about impacts [of drum lines] on the south-western white shark population". Chapter 29 In: M. L. Domeier (ed). "[21] Shark author and diver Hugh Edwards said, "We're the intruders in the ocean and the sharks have got a perfect right to be there. Depending on government policy, dangerous sharks can be euthanased or transported out to sea, while other non-target marine life can be released. You might be thinking that culling sharks would decrease the risk of attack, however, thats not the case. These large species of animals have low reproduction rates and take very long to mature. "[75], George H. Burgess, the former[76] director of the International Shark Attack File, "describes [shark] culling as a form of revenge, satisfying a public demand for blood and little else";[77] he said shark culling is a "retro-type move reminiscent of what people would have done in the 1940s and 50s, back when we didn't have an ecological conscience and before we knew the consequences of our actions.

Long term shark control programs using shark nets and/or drum lines have been very successful at reducing the incidence of shark attacks at the beaches where they are installed. Sharks have existed for over 450 million years, and there's a reason for that. [69][6][31] They also say that shark culling is "outdated, cruel and ineffective". Stanley Heritage Cooler Combo Competition, Mulloway released into Sydneys Georges River, Dean Butler inducted into IGFA Hall of Fame, Calls to include fish, crustaceans and cephalopods to South Australian Animal Welfare Act, Calls to include fish, crustaceans and cephalopods. CONS: No more swimming/surfing/kayaking etc. In South America, for example, vampire bats are responsible for the transmission of the deadly rabies virus. 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". Sonar devices known as Clever Buoys are said to detect all varieties of marine animals over two metres long, based on the way they move through the water. [2][3][4][5][6][7] Government officials often cite public safety (attempting to reduce the risk of shark attacks) as a reason for culling. And what effect do they have on the marine environment? This can perfectly illustrate the effects of shark culling on the ecosystem. They help regulate the population and distribution of the species below them in the food chain, thus maintaining the diversity undersea.
