Scientists have long sought to farm the scarce seafood staple, but critics say animals are not suited to intensive methods

Scientists in Japan say they have developed a groundbreaking method of farming squid that could solve shortages of the seafood staple, amid warnings from environmental groups that aquaculture is incompatible with the animal’s welfare.

Researchers at the Okinawa Institute of Science and Technology (OIST) say their system produced a reliable supply of squid and has the potential to be commercialised.
