Alarming NEWS: sharks, rays and chimaeras face extinction risk from #overfishing. 3 species, including the Lost Shark, have not been reported for many decades and are now considered Possibly Extinct bit.ly/GlobalSharkSta… GlobalSharkStatus #GlobalSharkTrends#IUCNcongress
#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.
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 #GlobalSharkTrends study published in @ScienceMagazine reveals that #overfishing has more than halved shark & ray populations over the past 50-years causing widespread erosion of ecological function and exceptionally high extinction risk

New #GlobalSharkTrends analysis funded by @SharkRayFund serves as a #wakeupcall for urgent action to turn the tide for these extraordinary animals:
Chondrichthyans are an ecologically diverse and ancient lineage of over 1,199 fishes that occur in a wide range of estuarine, marine, and
even some freshwater habitats, dominating the higher trophic levels at the top of ecological pyramids
