 all tuna can be sushimi grade..  If it's looked after properly

The way we do it (probably better ways out there is you have a corer etc) 

Just behind the pectoral fin are some large scales (make a small cut behind each side) usually one side will pour out blood.

Spike the fish in the brain (if you want you can core the brain and feed a wire down the spine but I can't be farked) 

Remove gills and stomach,  including the heavy blood area in the stomach area around the spine..  

Pack on ice (we pack upside down) and fill stomach cavity with ice. You really need to chill the fish as fast as possible. 

Don't bother doing this to mack tuna (nothing you do is going to make that sushimi quality)

 if it's been frozen..  I wouldn't 

But if it's fresh it should be a pink colour (border line red)

If it's fresh and a deep red to almost black with blood I'd think twice 

You can always just slice a tiny sliver off (1-2mm thick)  and test it if it's fresh 

If the flesh near the skin has turned brown I'd cook it before eating as that's usually a sign it wasn't chilled fast enough

That was the way we used to do it from a commercial boat over east for the best chance of it being Japanese grade. I.e the core and wire through the backbone.

Not sure if you can tell from the fillet alone.

Taste it

Are you checking if you can eat it raw? 

Pretty sure all fish can be eaten raw, i've tried heaps, fresh whiting is great.

Another one i tried the other week was those little pippies in the sand, raw they are like a sweet little clam.
