FWIW, the "sushi" option for "white meat" isn't a good one for 2 reasons.  One, the taste is very bland and has all the palette pleasure of a rotten apple.  Two, the parasite factor.  May as well cook it.

OTOH, lake trout can inspire a decent sushi - particularly on a cracker with some flavor (triscuits, etc...) or even rolled in rice wrapped in a birch leaf.  Yeah, a birch leaf.  Get out the wassabi!
