About Us

Full Circle Aquaculture develops restorative aquaculture models that benefit people and ecosystems.

We specialise in community-centric sea ranching of the tropical sea cucumber species Holothuria scabra or Sandfish.

Sandfish are one of the most valuable tropical sea cucumbers in the world, and because of this they are also a longtime resident of the IUCN red list. A critically endangered species threatened by decades of overfishing.

These “earthworms of the ocean” are essential ecosystem engineers within the seagrass meadows they inhabit, enhancing the productivity, carbon sequestration and overall health of these threatened marine habitats.

Reintroduction of these animals to areas where their populations are threatened or already locally extinct has proven and meaningful ecosystem benefits, and the sustainable harvest of mature animals brings productive revenues into communities that were often entirely dependent on extractive fishing.
