Summary: Reef manta rays (Mobula alfredi), the second-largest ray species, are found in tropical Indo-Pacific waters. Their curious nature and life history make them vulnerable to human threats, leading to global population declines due to exploitation, habitat loss, and degradation. This study examines the impact of environmental factors on Maldivian reef manta rays in the Baa Atoll to inform conservation efforts and understand their behaviour better.

Abstract

“Reef manta rays (Mobula alfredi) are a marine planktivore within the family Mobulidae, recognised as the second largest species of ray. This ray is spread across a vast oceanic range, distributed within tropical and subtropical parts of the Indo-pacific. However, due to their inquisitive nature and limiting life history M.alfredi have become susceptible to anthropogenic threats. Global populations of reef manta rays have seen steep declines, resulting from exploitation and human influences such as habitat loss and degradation. As a result, research into this vulnerable species provides a better understanding of behavioural patterns, allowing for beneficial guidance for the creation of conservation strategies. This study in collaboration with the Manta Trust, aims to assess the influence of various environmental factors on Maldivian reef manta rays around Baa Atoll.”
