Abstract

Reef manta rays (Mobula alfredi) are large, filter-feeding elasmobranchs that are currently undergoing global population declines. Here, I use a combination of photo-identification techniques, stable isotope analyses, and acoustic and satellite telemetry to examine the movement patterns arid feeding ecology of M. alfredi in Seychelles. Manta rays displayed restricted movements away from aggregation sites, and occupied a unique trophic role at D'Arros Island. Collectively, my findings broaden our understanding of the biology of this vulnerable species in the Western Indian Ocean, and provide support to the establishment of Marine Protected Areas at two manta aggregation sites in Seychelles.
