Nissui cracks full farming cycle for octopus

The company hopes to ship fully farmed octopus to retailers and restaurants as early as 2020.

Japanese seafood giant Nippon Suisan Kaisha (Nissui) has successfully figured out how to farm octopus throughout the life cycle and plans to ship the product across Japan by as early as 2020, reports Nikkei Asian Review.

Nissui announced on June 8 it succeeded in April in hatching eggs of fully farmed octopus at its Oita Marine Biological Technology Center in Saeki, Oita Prefecture, in western Japan.

The seafood company confirmed a hatch of about 140,000 eggs produced by octopus conceived by artificial incubation.

Nissui will check the growing conditions, hoping to ship fully farmed octopus to retailers and restaurants across Japan as early as 2020.

Full-cycle aquaculture refers to artificial incubation of eggs produced by marine animals that were themselves conceived by artificial incubation.

There has been no full-cycle aquaculture technology for octopus, as they have a low survival rate of about 30 days after being hatched.

Other major seafood companies are making their own breakthroughs. Maruha Nichiro will next spring spend about JPY 500 million (€4.1 million/$4.6 million) to build a new hatchery for eggs of greater amberjack in Minamisatsuma, in the southern prefecture of Kagoshima.

The seafood company currently grows and ships juvenile fish imported from China.

The new hatchery will enable the company to incubate eggs in Japan. Young greater amberjack will be shipped to its own farms and to other farmers. The company expects to ship 300,000 greater amberjack a year.

Maruha Nichiro hopes a new hatchery will make a full-cycle aquaculture commercially available.

The company now imports juvenile fish to farm yellowtail, but plans to switch to aquaculture in Japan in the future.
