SUSHI GRADE means it was bleed and iced down soon after boating it, nothing else. damn near any local fish properly cared for will qualify as SUSHI GRADE. NON-SUSHI GRADE means it sat in the sun beating itself to death.
the sushi you get in restaurants/fishmarkets is 3+days old on the ice and properly cared for. what you catch and ice is the best available hands down.
