Cobia
Cobia is a firm, relatively fatty white fish that grills without falling apart and eats well raw — an unusual combination. It is the sole member of its family, related to nothing else on the counter. Farmed cobia reaches market size in around a year, which is why it is available at all.

The only member of its family, and one of the fastest-growing fish anyone farms.
Buy it if
You want white fish that behaves like a steak on the grill and doesn't need a basket to survive.
A family of one. Rachycentron canadum is the only species in Rachycentridae. It is not a bass, a snapper or a cod, and every name it is sold under — ling, lemonfish, black kingfish — borrows from a fish it is not related to.
Fatty for a white fish, firm for a fatty one. Most white fish are lean and flake apart under heat; most oily fish are soft. Cobia has enough fat to stay moist and dense enough muscle to hold together on grill bars, which is why the same fish turns up over live fire and as sashimi.
It grows absurdly fast. In warm water a cobia can reach around ten pounds inside a year, one of the few marine species where farming produces a large fish quickly. Nearly all cobia on the US market is farmed for exactly that reason.
Cook it to 130–135°F. The fillet is thick and keeps cooking after it leaves the heat, so judge it with a thermometer in the center rather than by what the surface is doing.

Common questions
What does cobia taste like?
Clean and mild, with more richness than cod or halibut — closer to a lean piece of swordfish or a firm mahi. It isn't fishy, and the fat carries seasoning, so it stands up to smoke and assertive marinades better than most white fish.
What else is cobia called?
Ling, lemonfish, black kingfish and crab-eater, depending on the coast. None of those names describes a real relationship — cobia is the only species in its family.
Can you eat cobia raw?
Yes, and it is common in sashimi and crudo, where the fat reads as soft and faintly sweet. As with any fish served raw, whether a particular piece is suitable depends on how it was frozen and handled, not on the species.
How do you keep cobia from drying out?
Pull it at 130–135°F. It has more fat than cod so it is more forgiving, but a thick fillet carries a lot of residual heat — the surface will look underdone while the center is already there.
