Innovative Aquaculture
We’re checking out the future of aquaculture at the Hawaiʻi Ocean Science and Technology Park at Keāhole Point, on Hawaiʻi Island — where unique seawater facilities support over 50 cutting-edge tenants!
We visit Blue Ocean Mariculture’s amazing open ocean, offshore fish farm and the hatchery that supports it. We explore Symbrosia, which is growing the native Hawaiian seaweed, limu kohu, as a supplement for livestock. And, we tour the huge outdoor culture ponds, where Cyanotech – Nutrex Hawai’i grows microalgae for human health supplements.
