Can You Freeze Bluefin Tuna?
Bluefin tuna will keep well, box it airtight, consume it before it fades.

Lean white fish is kind in the freezer — little fat to go off — but the flake structure is fragile, and thawing splits what the ice pried apart. After thawing, think seared steaks, grilling, or poke rather than serving plain.
