BREAKING: new study led by Brit Finucci finds that 1 in 7 species of deepwater sharks and rays are threatened with extinction, driven by shark liver oil markets and the meat trade.

It was a massive assessment, and we couldn't have done it without the most generous help of Cassie Rigby & the team at IUCN SSC Shark Specialist Group. Finally, it is Published. All sawfish species are now Critically Endangered, designated by IUCN Red List. The time for action is now.

Have common declined in abundance and body size in response to fishing? 🦈🎣

Have they shifted their distribution northwards in response to ? 🔥❄️🌎

We explore this in the paper below⬇️

Despite an increase in the total number of stingray records over time in Britain, the last common stingray recorded in the waters of Scotland and northern England (> 53°N) was 1991 and 1998, respectively.

Angelshark (blue) showed a very similar decline in reports at the start of the observation period, while the uptick in records and the sightings at the end of the observation period was very limited compared to the common stingray (black).

We reconstruct the population trajectory and distribution of the common stingray Dasyatis pastinaca around Great Britain, using opportunistic records, mostly obtained by recreational anglers from Sea Angler magazine

Catches reported by anglers showed no long-term trend over 50 years, but decreased from 1970 to 1995 and an increase in abundance since 1995. While records were found around much of Great Britain, nearly all were from south of 54°, and have contracted southwards since 2000.

Ryan Charles 🦈 presented some interesting updates from Important Shark and Ray Areas - ISRAs. As work continues on their designation, some general patterns are emerging: coastal and charismatic species are receiving more attention in ISRA proposals, whilst chimaeras are underrepresented
