New #GlobalSharkStatus analysis published in @CurrentBiology finds that #overfishing is driving one-third of shark, ray, and chimaera species toward global extinction: bit.ly/GlobalSharkSta… #HealthyOcean #IUCNcongress

New 8-year long #GlobalSharkSatus analysis warns of rising extinction risk for 391 sharks, rays and chimaeras bit.ly/GlobalSharkSta… #GlobalSharkTrends #Overfishing #BiodiversityCrisis #IUCNcongress

New #GlobalSharkStatus analysis funded by @SharkRayFund benefited from a doubling of scientific output over the last ten years. #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress bit.ly/GlobalSharkSta…

👉17 workshops,
👉353 participants
👉from 71 countries #GlobalSharkStatus

This study is based on 1,199 @IUCNRedList assessments which are scientific papers, DOIs;
👉supported by 21,000 citations,

New #GlobalSharkStatus analysis funded by @SharkRayFund is the 2nd global assessment of sharks, rays and chimaeras. Results: Twice as many species threatened with extinction as found in the 2014 analysis #biodiversity #GlobalSharkTrends #IUCNcongress

Alarming NEWS: sharks, rays, and chimaeras face unprecedented extinction risk from #overfishing. New study finds that 391 species of the 1,199 assessed are threatened: bit.ly/GlobalSharkSta… #GlobalSharkStatus #GlobalSharkTrends #IUCNcongress

In a new global analysis, experts:
👉assessed 1,199 shark, ray, and chimaera species against @IUCNRedList criteria
👉1/3 qualify as Critically Endangered, Endangered, Vulnerable

New #GlobalSharkStatus Fact: The second global assessment of chondrichthyan fishes finds twice as many species threatened as found in the first analysis in 2014 #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress bit.ly/GlobalSharkSta…

New #GlobalSharkStatus analysis finds that rays are the most threatened of the 3 chondrichthyan fish groups.
Threatened Assessed Species:
➡️ Rays: 41%
➡️ Sharks: 35.9%
➡️ Chimaeras: 9.3%

New #GlobalSharkStatus Fact: One-third of chondrichthyan fish species (sharks, rays, and chimaeras) are threatened with extinction; three may well be already gone. #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress bit.ly/GlobalSharkSta…

#Overfishing is THE problem:
➡️ Almost all (99.6%, 1,093 of 1,199) chondrichthyans affected by fishing.
➡️ Overfishing is main risk for all (100%) of the 391 threatened chondrichthyans.
➡️ About one-third of threatened species are also imperiled by habitat degradation.

#ClimateChange compounds #overfishing for 10% of threatened shark and ray species through two pathways: loss and degradation of coral reefs #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress bit.ly/GlobalSharkSta…

Poleward shifting distributions of sharks and rays combined with #overfishing result in steep declines at the warmer range edge #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress #ClimateChange bit.ly/GlobalSharkSta…

#ClimateChange compounds #overfishing resulting in steep declines at the southern range edge of the Thorny Skate, while more northerly populations are stable or increasing. Improved fisheries management will reduce #ClimateRisk #GlobalSharkStatus bit.ly/GlobalSharkSta…

It’s not all doom & gloom. New #GlobalSharkStatus analysis documents significant rebuilding for several species of skates achieved through science-based fishing limits; time is running out for a growing number of threatened sharks and rays! bit.ly/GlobalSharkSta… #IUCNcongress

New #GlobalSharkStatus analysis finds that the population status of three species (all skates) improved with the help of conservation action. #GlobalSharkTrends #GlobalSharkStatus #IUCNcongress bit.ly/GlobalSharkSta…

New #GlobalSharkStatus analysis funded by @SharkRayFund serves as a #wakeupcall and calls for urgent action to turn the tide for these extraordinary animals: bit.ly/GlobalSharkSta… #EndOverfishing #GlobalSharkTrends #IUCNcongress

#PressRelease: Experts classify one-third of shark, ray and chimaera species as threatened and urge conservation action to turn the tide for these extraordinary animals #GlobalSharkStatus #GlobalSharkTrends #Biodiversity #IUCNcongress bit.ly/GlobalSharkSta…

New #GlobalSharkStatus Fact: Depletion of shark and ray populations not only risks extinction and ocean imbalance, but squanders opportunities for sustainable fishing, tourism, and food security over the long term #GlobalSharkTrends #IUCNcongress bit.ly/GlobalSharkSta…

New #GlobalSharkStatus analysis warns that conservation action is urgently needed to:
➡️ Reverse declining trends
➡️ Prevent further extinction, ecosystem damage, and food insecurity
