Key Differences
Haddock is a North Atlantic fish known for its light flavor and slightly drier texture compared to other whitefish. Halibut, the largest flatfish, is found in both the North Pacific and the North Atlantic and is prized for its firm texture and mild taste.
The haddock is easily identified by its black lateral line and a distinctive dark spot above the pectoral fin. Halibut, on the other hand, is often recognized by its sheer size, diamond shape, and the fact that one side is typically white while the other is dark.
In culinary contexts, haddock is popularly used in British fish and chips due to its flaky texture. Halibut, being thicker and firmer, is versatile in cooking, suitable for grilling, baking, or pan-frying without falling apart.
Economically, haddock is generally more accessible and less expensive than halibut, which can be one of the most expensive seafood options due to its size and the demand for its high-quality meat.
Regarding nutrition, both haddock and halibut are excellent sources of protein and low in saturated fat, but halibut tends to have a higher content of healthy omega-3 fatty acids due to its larger fat reserves.
