I thought some here might be interested in this brief show on the Japanese national channel NHK; it is in English on NHK World and available here:
It profiles researcher Nakajima Ryuta who was actually an artist first (made some squid art), but went to a university in Okinawa and developed a system for cultivating oval squid (someone can ID this I hope).
The Art and Science of Squids: Nakajima Ryuta / Visiting Researcher, Okinawa Institute of Science and Technology Graduate University (OIST)/Artist - Direct Talk | NHK WORLD-JAPAN On Demand
In 2022, a research team at OIST announced that they had developed the world's first sustainable system for farming squid. Nakajima Ryuta, a member of this team, shares the secrets of their success.
