Fewer devil rays in the sea: Evidence of declining mobulid populations off India's coast
Conservation Science and Practice, Volume 8, Issue 8, August 2026.Manta and devil rays are declining globally due to targeted and incidental capture, but species‐specific assessments are limited by unmonitored fisheries. Using morphometric, demographic, and fishery metrics, we show for the first time in India long‐term (2013–2023) declines in Mobula mobular, Mobula tarapacana, Mobula birostris, and Mobula thurstoni ...

Fisheries Management and Ecology, Volume 33, Issue 4, Page 719-732, August 2026.ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters
Global Change Biology, Volume 32, Issue 8, August 2026.Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.
