What We Do

Training and support

We offer training on reef-restoration principles, ex situ spawning and rearing, disease/parasite management, water-chemistry management, live-food culturing, broodstock selection for thermal resilience, juvenile feeding regimes, and in situ spawn / post-settlement survival techniques

Bespoke spawning systems for restoration and research

We have designed systems for coral spawning, embryo-rearing, thermal stress experiments, and complete containerised / modular lab solutions. All systems can be customised to meet specific species, environmental, and project-scale requirements.

Our systems offer unlimited access to coral gametes for aquaculture, research, and reef restoration projects worldwide

International collaboration

Through collaborations with leading organisations and institutions worldwide, we’re deploying advanced coral-spawning systems and restoration technologies that empower local partners to revive fragile reefs at scale.

Recent collaborations include a landmark reef-regeneration facility in the Seychelles with Nature Seychelles, bringing ex situ coral-breeding and reef-recovery capabilities to the Western Indian Ocean for the first time

About us

Coral Spawning International works to restore the balance between people and the ocean by pioneering new approaches to coral reef recovery and resilience.


Our focus is on harnessing science, technology, and collaboration to ensure that coral ecosystems — and the communities that rely on them — can thrive for generations to come.

Through cutting-edge spawning research, large-scale restoration programmes, and global partnerships, we transform knowledge into action with lasting impact.

Building on Dr Jamie Craggs’ pioneering work, we have developed ground-breaking methods for the ex situ sexual reproduction of broadcast corals, making predictable spawning in captivity possible and enabling multiple spawnings per year. This innovation turns a once-a-year natural event into a reliable laboratory process — giving researchers and restoration practitioners consistent access to coral gametes and larvae and enabling genetically diverse, science-driven reef restoration at scale.

By unlocking year-round coral spawning and distributing scalable spawning systems globally, we expand who can participate in coral restoration — not only institutions located near living reefs. These advances support greater genetic diversity, selective breeding, and the development of potentially more resilient coral generations, while extending conservation impact across both tropical and temperate reef systems.
