A worrying 51% of shark, ray and chimaera species in the Arabian Sea and its adjacent waters (Red Sea, Arabian/Persian Gulf) are threatened with a high risk of extinction, says a new study published last week by SOSF project leader Rima Jabado and her co-authors. The open-access paper: “Troubled waters: Threats and extinction risk of the sharks, rays and chimaeras of the Arabian Sea and adjacent waters” marks the first comprehensive assessment of the conservation status of chondrichthyans in the North West Indian Ocean.
The region is hugely important: it’s home to 15% of all described chondrichthyans, with 30 species that are endemic to the North West Indian Ocean (found nowhere else in the world). In spite of this, relatively little was known about how species were faring in these actively fished waters. Rima and her colleagues used the IUCN Red List of Threatened Species Categories and Criteria to assess the extinction risk for 153 chondrichthyans. We’ve highlighted a few of Jabado et al.’s key findings from the paper, published in the journal Fish and Fisheries:
What are the numbers?
Which species do we need to worry about most?
Why are sharks in such troubled waters here?
