KAUST researchers are developing an AI tool to classify fish species based on economic value and population growth rate, aiming to aid sustainable fisheries management in Saudi Arabia. The tool will help identify species at risk of decline, supporting marine conservation and food security goals outlined in Saudi Vision 2030. Saudi Arabia aims to increase self-sufficiency in seafood production amid declining Red Sea fish populations. Why it matters: This initiative could significantly improve fisheries management and conservation efforts in the Red Sea, informing policy decisions and supporting sustainable food production in line with national objectives.
A KAUST-led research team used acoustic readings to reassess fish populations in the ocean's mesopelagic zone (200-1000m depth). Published in Nature Communications, their findings indicate that mesopelagic fish quantities may be ten times greater than current estimates. The study also suggests that open-ocean ecosystems are as efficient as coastal regions in nutrient cycling. Why it matters: This discovery assigns mesopelagic fish a potentially significant, previously unrecognized role in the global carbon cycle and highlights KAUST's contribution to marine science.
KAUST's VP for Research, Donal Bradley, discovered a new species of sea bream near Thuwal, Saudi Arabia, named *Acanthopagrus oconnorae* or Bev Bradley’s Bream. Bradley noticed unique features like a shallow forehead and black gill patch and collaborated with the Red Sea Research Center for genetic analysis. The discovery involved multiple researchers and even the KAUST Fishing Club to collect more specimens. Why it matters: This highlights the biodiversity research happening in the Red Sea and KAUST's role in advancing marine science in the region.
KAUST and MEWA's Aquaculture Development Program (ADP) showcased achievements at the 6th International Saudi Aquaculture Development Workshop. New fish nutrition formulations developed by KAUST Beacon Development (KBD) could save Saudi Arabia $417 million per year in aquaculture production costs by 2030 through improved feed conversion ratios. KBD has also established complete production cycles for Sobaity and Gilthead seabream under Red Sea conditions. Why it matters: These advancements boost Saudi Arabia's food security and promote sustainable aquaculture, reducing reliance on imports and diversifying the economy in line with Vision 2030.
A KAUST article highlights the threats to Saudi Arabia's coral reefs from pollution, rising ocean temperatures, and overfishing. Prof. Michael Berumen notes an imbalance with too many fish in markets and not enough on reefs, advocating for sustainable fishing. Saudi Arabia's reefs benefit from a relatively low population along the Red Sea coast and the absence of large river systems. Why it matters: Protecting these reefs is crucial for preserving marine biodiversity and ensuring the long-term health of Saudi Arabia's coastal ecosystems.
KAUST's Bluefin, a fish wearable technology developed by Professor Muhammad Mustafa Hussain, won the CES Innovation Award. The device measures water temperature, pressure, depth, and pH levels, functioning for a year at a depth of 2km while weighing only 2.4 grams. Bluefin will be available to scuba divers, naval forces, and fisheries for marine life tagging. Why it matters: This award recognizes KAUST's contributions to marine research technology and positions the university as a global leader in applying advanced engineering to ecological monitoring.
A KAUST-led study tracked coral grouper movements in Australia's Great Barrier Reef over 20 years. Researchers genotyped thousands of coral grouper to map larval dispersal patterns from no-take zones. They found that no-take zones ensure a consistent supply of fish stocks, benefiting both conservation and fisheries. Why it matters: The study demonstrates the value of marine protected areas for biodiversity and fisheries management, providing insights for effective reserve design.
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.
