From January 2022, NTT East, Ichii, and Okayama University of Science have been conducting a “demonstration experiment for the commercialization of a completely closed circulation land-based aquaculture.” They have succeeded in land-based sockeye farming for the first time in the world, and are conducting test sales at Ichii stores. At ICHII’S Rocinante MARKET Fukushima Nishi store, they provided raw edible sashimi (fillets and fences) and sushi. Through marketing activities such as sales, they will start considering full-scale commercialization. Sockeye salmon raised in land-based aquaculture in a completely closed circulation system using suitable environmental water generally takes about four years from juvenile to adulthood, but in a year and a half, they grow to a length of about 50 centimeters and a weight of 1.2 kilograms, making it a size that can be shipped and sold.
