About Us
At Coral Spawning International, we utilise cutting-edge science and technology to drive effective conservation efforts. Our approach enables us to make informed decisions and implement targeted strategies for the preservation of coral reefs and marine ecosystems.

Selective Breeding for Resilient Corals
Our long-term ambition is to develop selective breeding methods that produce coral strains with greater resilience to environmental stress. We are actively building the research foundations and technical capacity to achieve this
Advanced Research & Monitoring
Building on over two decades of coral reproduction research, our team uses controlled environmental systems, precise monitoring tools, and refined spawning techniques to better understand and optimise coral reproduction
Accelerating Reef Repair
By cultivating coral gametes and larvae in controlled settings, we aim to accelerate reef recovery and improve restoration outcomes in regions where coral ecosystems are declining
International Collaboration
We work with global research institutions, aquaria, NGOs, and community-led conservation groups to expand access to coral spawning technologies and accelerate reef restoration at scale
Public Education & Awareness
Through storytelling, outreach, and media engagement, we help broaden public understanding of coral biology, reef decline, and the pathways to recovery

How Our Work Helps Coral Reefs
Buying Time for Nature
By increasing the reliability and scale of coral propagation, we help reefs better withstand current climate pressures while long-term mitigation efforts progress
Kickstarting Reef Recovery
Controlled spawning and larval rearing offer a critical boost to natural recovery processes, especially in areas where wild coral reproduction has become unreliable
Enhancing Natural Resilience
By refining spawning protocols and improving larval survival, we support the development of corals better able to withstand a changing ocean environment

Our Story
​Coral Spawning International was founded by Dr Jamie Craggs and Kate Craggs, a husband and wife team combining world-leading coral reproductive science with the partnerships and systems needed to deliver restoration at scale.
​
Dr Jamie Craggs
Jamie is an award-winning coral reproductive biologist and a global pioneer of ex situ coral spawning techniques. His career began as a coral aquarist, where hands-on experience with coral husbandry led him to tackle one of coral science’s greatest challenges: understanding and controlling coral spawning.
Through the creation of Project Coral, Jamie achieved the first predictable broadcast spawning of corals in controlled environments, transforming a rare natural event into a repeatable scientific process. This breakthrough fundamentally advanced coral reproductive science and enabled new pathways for research, aquaculture, and reef restoration based on genetic diversity and resilience. Today, Jamie’s methods underpin coral spawning systems and programmes used by leading aquariums, research institutions, and conservation organisations worldwide.
​
Kate Craggs
Kate brings the strategic and operational perspective that turns pioneering science into real-world impact. With a background in project coordination, relationship management, and collaboration across conservation and industry, she plays a central role in shaping CSI’s direction and delivery.
Kate leads the development of partnerships with conservation organisations, technology providers, suppliers, and sponsors, ensuring coral spawning innovation is matched with practical implementation. Her focus is on building strong, trusted collaborations that allow complex scientific projects to function, scale, and endure.
​
Together
Together, Jamie and Kate founded Coral Spawning International to bridge the gap between scientific discovery and applied reef restoration. Their shared mission is to advance coral spawning as a core tool for reef resilience—combining innovation, collaboration, and evidence-based practice to support reefs now and into the future.

Restoring reefs through science, innovation, and global collaboration
Our Mission
Coral Spawning International’s mission is to advance innovative, science-driven strategies for coral reef restoration. We work to make coral reproduction predictable, accessible, and scalable — empowering researchers, practitioners, and communities worldwide to rebuild resilient reefs. By uniting cutting-edge technology with practical restoration solutions, we aim to secure a sustainable future for marine ecosystems and the people whose livelihoods depend on them.
Our Vision
Our vision is a world in which coral ecosystems — and the communities that rely on them — can thrive for generations to come. Through the power of science, technology, and global collaboration, we strive to restore reef resilience at scale, expand who can participate in coral conservation, and safeguard the biodiversity that underpins healthy oceans and coastal societies.
