Cover Story: Whale sharks seasonally aggregate in Djibouti, supporting ecotourism activities. However, environmental factors influencing their relative abundance at this site are not well understood. This study analyses the environmental drivers of immature whale shark surface sightings in the Gulf of Tadjoura across a five-year period using GAM and Hurdle model. Based on 111 sightings and 83 photo-identified individuals, sea surface chlorophyll-a (SSC) concentrations and sea surface temperature (SST) significantly affected whale shark relative abundance, while wind strength showed weaker effects. Understanding how environmental factors influence prey availability and, consequently, whale shark surface sightings is essential for effective management and conservation of this species within this area. View this paper
