TOKYO — Fisheries giant Kyokuyo and Nippon Formula Feed aim to begin shipments in 2017 of farmed bluefin tuna hatched in captivity, helping to provide stores and eateries with a stable supply amid tighter restrictions on tuna catches.
Together, they aim to ship about 200 tons a year — the most ambitious project yet by any Japanese fish-farming company.
The goal of full-cycle aquaculture, the method used by the companies, is to reduce dependence on natural sources of fish. Eggs taken from the wild are artificially inseminated and hatched in captivity. First-generation farmed fish are then bred to produce the second generation, and so on.
