What is Sushi grade fish? Un-bruised fish that are thoroughly bled out then flash frozen. Japanese fishermen remove the brain of tuna with a coring tool then run a wire down the center of the backbone. They then cut a slit behind the pectoral fin on each side and slowly bleed the fish. (It’s heart continues to beat) Usually they cut out the gills also. To prevent initial bruising they give the live fish a shot of alcohol which the fish absorbs in about 3 seconds and passes out, with smaller tuna they just cover with a blanket and hold them down while they bleed them.
