Industrial aquaculture parks an intensive alternative for land-based seafood production

Industrial aquaculture parks that employ hyperintensive culture technology are a promising alternative for further land-based seafood production. They offer wide siting options, efficient land and water resource use, and high-density, high-yield production output. In Project Raceways, a five-nation consortium is developing protocols for the culture of several highly valuable species of marine fish in raceway systems.
