Description: The project was dedicated to preserving and managing the sustainable exploitation of white sea cucumber (Holothuria fuscogilva) species in French Polynesia through advancements in aquaculture practices. It aimed to comprehensively understand the species’ habitats and populations. Conducting surveys and identifying juvenile habitats in the Vairao lagoon were pivotal components, with collaboration from the Marine Resources Directorate and Pacific Community experts in defining sampling protocols for adult stocks. Local engagement played a crucial role in pinpointing suitable sites, particularly for juvenile sea cucumbers, ensuring community participation. Outcomes involved the comparison of three stock assessment methods across a 48-hectare coastal area, providing insights into cost-effectiveness, population counts, and equipment requirements. Collaborative efforts with local fishermen resulted in mapping 10 specific sites totalling 0.5 km2 within the lagoon, where adult sea cucumbers were located. Recorded stock densities ranged between 65 to 73 individuals per hectare, contributing valuable information to ascertain the technical feasibility of aquaculture, sea ranching, and sustainable exploitation of the species. The findings also highlighted potential areas for juvenile sea cucumber reseeding in Polynesian lagoons.
