Fewer devil rays in the sea: Evidence of declining mobulid populations off India's coast

open access: yesConservation 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 ...
