Like most sushi fish (3)
I believe the answer is:
raw
'like most sushi fish' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for raw that I've seen before include "Untried (of recruit) - uncooked (of meat)" , "Red and inflamed" , "Like a recruit" , "Naked" , "Not cooked" .)
