Wild yellowfin, bigeye, and albacore.

The vast majority of tuna we consume at even high end sushi restaurants are labeled wild but are actually “ranched”.
Few if any of the sushi places I’ve been to (high-end or otherwise) say wild or otherwise. They just say maguro, hamachi, kihado, or whatever. Most likely the bluefin I’ve had at high-end places was “ranched.”
Sushi places that aren’t high-end either don’t have bluefin.or it costs twice or more what anything else does. If it says “maguro” but costs the same as yellowfin, it’s not bluefin.
