Increasing human demand for fish has led to a serious global problem of fisheries exhaustion, especially in small island states like Kiribati. This project is a pavilion design near Betio Port in capital city of Kiribati: Tarawa, to sustain fish-human-ocean relations. Submergence creates a shared experience, bring together Kiribati islanders, tourists and local fish species. The pavilion comprises a snorkeling space, seaweed farm, vegan ocean snack spot and shelter for juvenile fish. It encourages fish to safely share space with humans, and supports new oceanic crops by developing more-than-human environments, spatial practice can reduce the impact of overfishing, provide new livelihoods for local islanders, and spread ecological awareness.
