Bending back the curve of shark and ray biodiversity loss
Sharks and rays are sentinels of the state of the ocean. Since the mid-twentieth century, overall abundance has declined by nearly 65% and over one-third (37.5%) of species are threatened, causing widespread changes in community structure. This crisis stems from unregulated fisheries expansion coupled with inadequate catch-and-trade monitoring that fail to account for the complexity of shark and ray products, their use and global trade flows.
