KAUST researchers, in collaboration with WHOI, studied whale shark movement patterns near the Shib Habil reef in the Red Sea over six years using visual census, acoustic monitoring, and satellite telemetry. The study monitored 84 sharks and found the aggregation to be highly seasonal, with sharks most abundant in April and May, returning yearly. The site may serve as a nursery for the wider Indian Ocean population, attracting juvenile females, which is unique to Shib Habil. Why it matters: Understanding whale shark behavior and critical habitats like Shib Habil is vital for future conservation efforts of this endangered species in the Red Sea and the broader Indian Ocean.
KAUST marine scientists, led by Dr. Michael Berumen, tracked 47 whale sharks near Al-Lith in the Red Sea using satellite tags. The study, published in PLOS ONE, identifies the area as a significant nursery for the species. The research provides valuable insights into the movement patterns of whale sharks. Why it matters: Understanding these patterns is crucial for effective conservation efforts for this vulnerable species in the Red Sea.
An international team including KAUST researchers tracked nearly 2,000 sharks using satellite tags to map their movement and space use. The study found that 24% of shark habitats overlap with pelagic longline fisheries, with higher overlap for commercially exploited species. For North Atlantic blue and shortfin mako sharks, the overlap was 76% and 62% respectively. Why it matters: This research highlights the vulnerability of sharks to industrial fishing and underscores the need for targeted conservation efforts in critical habitats.
A global census, with KAUST participation, assessed reef shark populations using Baited Remote Underwater Video Systems (BRUVS). The study found reef shark populations thrive where there are marine conservation policies and fishing regulations. However, they are scarce in areas with overfishing and poor resource protections, with sharks absent on nearly 20% of surveyed reefs. Why it matters: The research highlights the importance of conservation management for reef sharks, key apex predators and indicators of reef health, especially in the Red Sea region.
KAUST doctoral student Royale Hardenstine is conducting whale shark research in the Red Sea. The research is captured in a video produced by KAUST. Why it matters: This highlights KAUST's ongoing research efforts in marine biology and Red Sea ecosystems.
