IUCN global study 2010 [1]

IUCN) is the world's oldest global environmental organization.[2] It evaluates threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened:[3]

Vulnerable species
Endangered species
Critically endangered species

The term threatened strictly refers to these three categories (critically endangered, endangered and vulnerable), while vulnerable is used to refer to the least at risk of these categories.

red-listed species, as they are listed in the IUCN Red List of Threatened Species.[4]

In a milestone decision in 2013, CITES prohibited international trade in the fins of the scalloped hammerhead (pictured) and four other shark species.[5]

Shark species are increasingly becoming threatened because of commercial and recreational fishing pressures, the impact of non-shark fisheries on the seabed and shark prey species, and other habitat alterations such as damage and loss from coastal development and marine pollution.[6] Rising demands for shark products has increased pressure on shark fisheries, but little monitoring or management occurs of most fisheries.[7] Major declines in shark stocks have been recorded over the past few decades; some species had declined over 90% and population declines of 70% were not unusual by 1998.[8] In particular, harvesting young sharks before they reproduce severely impacts future populations. Sharks generally reach sexual maturity only after many years and produce few offspring in comparison to other fish species.[9]

Conservationists estimate that up to 100 million sharks are killed by commercial and recreational fishing every year.

pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by high-seas fisheries were threatened with extinction.[16][17][18]

In 2010, the Convention on International Trade in Endangered Species (

dogfish sharks. The majority, but not the required two-thirds of voting delegates, approved the proposal. China, by far the world's largest shark consumer, and Japan, which battles all attempts to extend the convention's protections to marine species, led the opposition.[19][20]

In 2013, CITES member nations overcame the continued opposition led by China and Japan,[21] and reversed course.[22][23] In what CITES has called a "milestone", the oceanic whitetip, porbeagle, and three species of hammerheads will now join the great white, basking and whale shark on CITES Appendix II, effective September 2014.[24] International trade of these species is thus prohibited without CITES permits, "... and evidence will have to be provided that they are harvested sustainably and legally."[5]

In 2014 the state government of

drum lines are deployed near popular beaches using hooks designed to catch the vulnerable great white shark, as well as bull and tiger sharks. Large sharks found hooked but still alive are shot and their bodies discarded at sea.[26] The government claims they are not culling sharks, but are using a "targeted, localised, hazard mitigation strategy".[27] Barnett has described opposition to killing the sharks as "ludicrous" and "extreme", and said that nothing can change his mind.[28]

According to a 2021 study published in the journal

fishing pressure in the oceans has increased by a factor of 18 since 1970.[29] This overfishing has resulted in the number of oceanic sharks and rays declining globally by 71%, and has increased the global extinction risk to the point where three-quarters of these species are now threatened with extinction. Precautionary science-based catch limits and strict prohibitions are now needed urgently if population collapse is to be avoided,[30][31] if the disruption of ecological functions is to be averted,[32] and if a start is to be made on rebuilding global fisheries.[33][29]
