Vat sushi

Hmmm:

 

Although I remain very skeptical of how beef or chicken meat grown from cells in a vat can be converted into something with the same texture as the muscle fibres we eat from those animals,  I can imagine how it should be easier to copy the simpler texture of raw fish with vat grown cells. 

This company is still just doing it experimentally.  I don't know if the nutrient broth the cells need to grow in is simpler than that needed for mammalian meat - but I presume it would be.   But I still have my doubts that it is ever likely to be a cheaper or better way of doing it than aquaculture.
