Untangling a Manta Ray

ALT Infographic (in English, Sinhala, and Tamil) highlighting the key messages from the publication. This includes the 6 mobulid species found in Sri Lanka (Oceanic Manta Ray; Bentfin Devil Ray; Spinetail Devil Ray; Sicklefin Devil Ray; Longhorned Pygmy Devil Ray; and the Shortfin Pygmy Devil Ray). It highlights that Blue Resources Trust have conducted 1,246 surveys between 2011 and 2020 and that results show declining body sizes (1-2% per year) in 3 species, declining annual catches of mobulid rays since 2010, that total annual captures by Sri Lankan artisanal fleets exceed estimated total annual capture in all global industrial purse seine fisheries combined, and that estimates of spinetail devil ray mortality exceed their growth rates. All indicate unsustainable fishing of manta and devil rays in Sri Lanka. Recommendations include fully protecting them, implementing CMS and IOTC conservation measures, encouraging proactive fisheries management, and implementing best handling and release
