Overview

Observational analysis documents population demographics and residency patterns of whale sharks in Bird's Head Seascape, indicating threats from fisheries.

Key Points

  • The population of whale sharks exhibits a strong male bias, with a ratio of 8.8:1.
  • Over half of the whale sharks were re-sighted at least once, highlighting high re-sighting rates in key habitats.
  • Lagged Identification Rates showed significantly higher residency times in Cenderawasih Bay compared to Kaimana.
  • Scarring was present in 76.9% of individuals, indicating ongoing interactions with fisheries and tourism.
