Since 2006, the tropical multi-species aqua-farm has contributed to food security by providing sustainable supplies of organic oysters, milkfish and tilapia. Now they are also cultivating and harvesting micro-algae as livestock feed for the fish. Fish are co-farmed with shellfish and micro-algae in inland ponds, drawing on the tropical climate, natural nutrient cycles and new harvesting technologies. By providing locally-made, algae-based feed, the project is tapping into an under-served market of 8,000 seafood-loving residents and 90,000 visitors in the Cook Islands.
