In 2010 a global IUCN study of vertebrates found that of 1,044 cartilaginous (ray and shark) species examined, 345 or 33% were threatened with extinction. [6] [7] There are four orders of rays: stingrays, skates, electric rays and sawfishes. Like sharks, rays are relatively long living and thrive in stable populations.
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]

The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
The University of Florida’s International Shark Attack File finds that there were a total of 57 shark bites in 2022, marking a 10-year low Mapped: World’s shark attack hotspots revealed Skip ...
While it's a statistical fact that the shark population is shrinking (a 2021 global study published in Nature found the world’s population of oceanic sharks and rays has fallen by 71%) some ...
[128] [129] In 2021, it was estimated that the population of oceanic sharks and rays had dropped by 71% over the previous half-century. [7] Shark finning yields are estimated at 1.44 million metric tons (1.59 million short tons) for 2000, and 1.41 million metric tons (1.55 million short tons) for 2010.
With the rise in demand for shark products there is a greater pressure on fisheries. [29] Sharks experience a long interval between birth and sexual maturity, such that many sharks never reach maturity. In some species, populations have declined by over 90% over the past 20–30 years with decline of 70% not unusual. [30]
