Significant progress has been made in advancing priority actions to conserve manta and devil rays, yet implementation and enforcement of protective measures often fall short, leaving most mobulid populations at risk of overfishing. Drawing on a literature review, fisheries databases, agency reports, and expert interviews, we assess global trends in mobulid catch and mortality. We examine both targeted and incidental catch, in small (<15 m, ‘SV’) and large (>15 m, ‘LV’) vessel fisheries to identify hotspots with the highest risk of fisheries-related mortality and population decline. We estimate global fisheries catch at 264,520 (184,407–344,987) mobulids per year, with SV fisheries accounting for 87 % of global mortality. The highest-risk hotspots, based on mortality and declines, are located in India, Indonesia, Sri Lanka, Peru, and Myanmar. Mobulid retention is driven by demand, with higher mortality rates observed in countries exporting gill plates, and to a lesser extent, in those trading meat domestically or internationally. We recommend urgent implementation and enforcement of mobulid listings under the Convention on International Trade in Endangered Wild Flora and Fauna (CITES), the Convention on the Conservation of Migratory Species of Wild Animals (CMS), and national...

La estructura de clasificación de la lista de especies Blue Five para la biblioteca digital ha sido elaborada siguiendo criterios tanto científicos como de accesibilidad para facilitar la búsqueda de información. En primer lugar, se organizaron las especies basándose en la taxonomía aceptada por la comunidad científica para garantizar precisión y coherencia. Simultáneamente, se han implementado categorías y subcategorías, considerando características morfológicas, su distribución y el uso de los nombres comunes, con el fin de optimizar la navegación y búsqueda de datos por parte de los usuarios. Esta metodología equilibrada asegura que la lista no solo sea científicamente rigurosa, sino también fácil de consultar para quienes necesiten acceder a información específica de manera eficiente.
