Boneless Fish is a fish-based frozen food brand and grocery product, the process in the production of which was invented by Dairei Corporation (大冷株式会社) of Japan in 1998. It is essentially a fish that has been scaled, gutted and deboned by a skilled worker before being reassembled with a transglutaminase to look like a dressed fish (fish gutted and with its head and fins removed). The fish is then flash-frozen and packaged, remaining uncooked. It is possible to manufacture a boneless fish with head and fins intact, but it had been found to be impractical.
