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 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.
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 study published in PNAS quantifies the potential for increased food supply through coral reef restoration. Analyzing over 1,200 reef sites, the research estimates that rebuilding depleted fish populations could increase sustainable yields by nearly 50%. For Indonesia, this could translate to 162 million additional servings of reef fish annually. Why it matters: The study provides crucial evidence for governments to strengthen food security and ecosystem resilience through fisheries management, especially in regions facing high malnutrition.
KAUST and the Saudi Ministry of Environment, Water and Agriculture (MEWA) are collaborating on the Aquaculture Development Program (ADP) to advance Saudi Arabia's food security goals under Vision 2030. The ADP aims to increase domestic seafood production to 530,000 tons annually by 2030 through sustainable aquaculture practices. KAUST is employing a multidisciplinary team and innovative approaches like Integrated Multitrophic Aquaculture (IMTA) to optimize resource use and minimize environmental impact. Why it matters: This partnership aims to transform Saudi Arabia's aquaculture sector, reducing reliance on imports and promoting economic diversification while preserving marine biodiversity.
KAUST researchers are exploring the link between nutrition and brain-energy metabolism to address cognitive decline, dementia, and Alzheimer’s disease. Dr. Pierre Magistretti and Dr. Johannes le Coutre are collaborating on ways to merge brain-energy metabolism research into the field of nutrition. They published an article entitled “Goals in Nutrition Science 2015-2020” in the journal Frontiers in Nutrition. Why it matters: This research could lead to nutritional interventions to hinder or prevent cognitive decline, offering a new approach beyond traditional drug treatments.
KAUST researchers have discovered how sea anemones recycle nitrogen waste, allowing them to thrive in nutrient-poor ocean environments. The study used laser microdissection and single-cell RNA-sequencing to analyze tissue-specific gene expression in Aiptasia. They found that anemones distribute glucose received from symbionts across tissues to recycle nitrogen waste. Why it matters: This research enhances understanding of coral reef ecosystems and their resilience, which is particularly relevant for Red Sea biodiversity and Saudi Arabia's environmental efforts.
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.
