Discover How Cod Changed the History of Cooking
From frigid northern waters to bustling global markets, cod—known as “bacalao” in Spanish and “bacalhau” in Portuguese—has fed civilizations, shaped trade routes, and inspired iconic recipes. Explore where cod live, how they evolved, the differences among species, and why this humble fish transformed culinary history.
Where cod are found
- Atlantic cod (Gadus morhua): Cold-temperate North Atlantic—Barents Sea, Norwegian Sea, Iceland, Greenland, North Sea, and the Grand Banks off Newfoundland.
- Pacific cod (Gadus macrocephalus): North Pacific—Bering Sea, Gulf of Alaska, Sea of Okhotsk, and coastal waters of Japan and the U.S. West Coast.
- Habitat: Demersal (bottom-dwelling) fish favoring continental shelves, banks, and fjords; depth ranges typically 50–300 m, with seasonal migrations.
- Temperature preference: Thrive in cold waters (~2–10 °C), with regional stocks adapting to local currents and prey availability.

Evolution and species differences
- Family Gadidae: Cod belong to the Gadidae family, which includes haddock, pollock, and whiting—species that diverged to exploit different niches in cold-temperate seas.
- Atlantic vs. Pacific cod: Atlantic cod typically grow larger and have distinct barbel and lateral line patterns; Pacific cod mature earlier and show stock-specific growth rates.
- Adaptive traits: Buoyant swim bladders, sensitive lateral lines, and seasonal migrations optimize feeding on capelin, herring, and crustaceans.
- Human-driven selection: Centuries of fishing pressure influenced stock structure, spawning timing, and size-at-maturity in some regions.
Accurate facts and culinary impact
- Preservation power: Salted cod (bacalao) and air-dried stockfish enabled long-distance trade and year-round protein before refrigeration.
- Global dishes: Iconic recipes include Portuguese bacalhau à Brás, Spanish bacalao al pil-pil, Italian baccalà mantecato, and Caribbean cod fritters.
- Nutritional profile: Lean protein, omega‑3 fatty acids, vitamin B12, iodine—key for coastal and inland diets across Europe and the Americas.
- Trade routes: Northern fisheries supplied Mediterranean markets, shaping merchant networks and culinary traditions for centuries.
