Overfishing has halved populations of chondrichthyan fishes – sharks, rays, & chimaeras – since 1970. Target fisheries & incidental capture (bycatch) has resulted in over 1/3 threatened with extinction.

@iucnshark.bsky.social red list assessments & is widely used to report on status of terrestrial biodiversity & conservation, yet there is no equivalent for the oceans

New global analysis, experts calculate aquatic RLI for 1,199 sharks, rays & chimaeras from 1970 to 2020.
👉 over 1/3 qualify as Critically Endangered, Endangered, Vulnerable
👉 Red List Index has worsened by 19% since 1970
