The team at the Environmental Science Centre, Qatar University, supported by Coral Spawning International, are tackling one of the region’s most urgent environmental challenges: the rapid decline of coral reefs in the Arabian Gulf. Despite the remarkable tolerance of local coral species to extreme conditions, mass bleaching and mortality events – driven by climate change and coastal development – have devastated coral cover and diversity in recent decades. The project is dedicated to reversing this trend and supporting the recovery of Qatar’s coral reef ecosystems, which are vital for both marine biodiversity and the services they provide to people.
The project aims to develop innovative, locally adapted technologies to support coral reef recovery. Its focus is on enabling the sexual reproduction of native coral species within land-based coral spawning systems, while strengthening natural reef populations through the introduction of genetically diverse coral offspring.
To achieve these goals, the project is advancing methods to control the reproductive cycles of selected coral species and improve coral recruitment on degraded reefs. This includes directly seeding reefs with larvae reared in ex-situ systems, as well as outplanting juvenile coral colonies to help rebuild populations of threatened species.
CSI work is at the forefront of coral science. By manipulating environmental cues such as temperature, light, and lunar cycles, we can synchronise and control coral spawning in captivity. We are also addressing key bottlenecks in coral restoration, such as high post-settlement mortality, by experimenting with improved husbandry protocols – ranging from feeding regimes to co-culturing strategies that reduce competition and stress.
The expertise and infrastructure CSI provides not only advance restoration in Qatar but also provide a platform for future research into coral biology, disease, and resilience. This project opens the door to emerging fields like selective breeding, assisted gene flow, and microbiome manipulation, all of which could further boost coral survival in a changing world.
The team at the Environmental Science Centre has already mapped and surveyed Qatar’s coral habitats, identifying both the challenges and the opportunities for restoration. The coral spawning systems have been operational since 2022, and through training delivered by CSI the team are successfully inducing out of season spawning events and rearing juvenile corals. These efforts are laying the groundwork for large-scale restoration and for sharing our knowledge with the wider scientific and conservation community.
Looking ahead, we are supporting the project team as they prepare to launch thermal stress experiments to assess how different coral species and lineages respond to rising temperatures. By combining controlled breeding with environmental stress trials, the research aims to determine whether corals can be bred or conditioned to better withstand the impacts of climate change.
The long-term objective is to develop restoration techniques that can be implemented at scale, maximising impact for Qatar’s reefs and providing a model for coral restoration across the wider region.
