Icelandic Cod: A Guide to Iceland’s Most Famous Fish

From drying racks along shorelines to restaurants in Reykjavík, Icelandic cod is woven into the fabric of life in Iceland. For centuries, this valuable fish helped sustain communities through harsh northern winters and shape the country’s trading economy. Today, cod remains an important part of the North Atlantic marine ecosystem and a cornerstone of cuisine in Iceland.

What Is Icelandic Cod?

The term Icelandic cod does not describe a distinct biological species. Instead, it refers to Atlantic cod (Gadus morhua) that live, feed and reproduce in the cold, nutrient-rich waters surrounding Iceland.

Cod are demersal fish, meaning they live and feed primarily near the seabed. They have long, muscular bodies with mottled greenish-brown or grey colouring that helps them blend into their surroundings. Beneath the lower jaw is a small, sensitive barbel, a whisker-like organ that helps locate prey on or near the seabed. Adult cod are apex (top) predators and well adapted to feed on variable availability of prey such as capelin, herring and crustaceans being the most important ones.  In turn, their juveniles form part of the diet of other marine predators.

Atlantic cod are among Iceland’s most iconic marine animals. Adults commonly measure between 50 and 100 centimetres (20–39 inches). Exceptional individuals can even exceed 1.5 metres (5 feet) in length and weigh more than 40 kilograms (88 pounds).

Why Is Cod Important to Iceland?

It is difficult to overstate the role of cod in shaping Icelandic culture and commerce. From the settlement period until well into the 20th century, survival on the island depended on farming and seasonal fishing. Alongside livestock such as sheep, cows and horses, coastal communities relied on cod for food and as a valuable commodity for trade.

Historically, Icelandic cod was preserved by wind-drying it on wooden frames known as hjallar or by salting it. These methods allowed the fish to be stored for long periods and exported as stockfish or saltfish (saltfiskur). Fishing seasons broadly followed the movement of cod towards their spawning grounds. Historically, much of this activity took place during late winter and spring.

Nowadays, Iceland’s waters support an interconnected community of fish, marine mammals, various marine invertebrates as well as seabirds. Within the marine ecosystem, cod remain major predators as well as one of Iceland’s most important commercial fish. Scientific stock assessments, catch limits and long-term management plans are essential to maintaining healthy, sustainable populations for future generations.

Where Do Icelandic Cod Live?

Rather than gathering at fixed locations, Icelandic cod range widely across the continental shelf surrounding the island. They inhabit both coastal and offshore waters, commonly found in temperatures between 2°C and 7°C (35°F and 45°F). Adult cod are frequently found at depths of around 100 to 250 metres (328 to 820 feet). However, they can occupy much shallower or deeper waters depending on age, season and availability of food.

Different groups of cod move between feeding and spawning grounds throughout the year. The main spawning areas lie off Iceland’s southern, southwestern and western coasts, where relatively warm Atlantic waters influence the environment. Spawning takes place mainly in March and April, although smaller regional groups reproduce in other areas around the country.

When Is Icelandic Cod Fishing Season?

Commercial fishing for Icelandic cod now takes place throughout the year rather than during one fixed season. However, fishing locations and catch volumes vary according to weather, cod movements and the availability of quota.

Late winter and spring form the main spawning season. Temporary closures are introduced in certain areas to protect spawning cod, with restrictions sometimes applying to particular fishing methods or vessels. Overall catch limits are based on scientific stock assessments and advice from the Marine and Freshwater Research Institute.

Visitors can join seasonal sea-angling tours from Reykjavík and several other coastal communities. Cod are commonly caught on these excursions, but success depends on sea conditions, location and movements of the fish.

Eating Icelandic Cod

Fresh Icelandic cod is celebrated for its mild, slightly sweet flavour and firm, flaky white flesh. Its versatility makes it suitable for everything from simple pan-frying to traditional stews and preserved foods.

Popular ways to enjoy cod in Iceland include:

• Pan-fried cod: Often served with butter, potatoes and roasted root vegetables.
• Plokkfiskur: A traditional Icelandic fish stew or mash made with flaked whitefish, potatoes, and onions.
• Harðfiskur: Air-dried fish, often cod or haddock, eaten as a protein-rich snack and commonly spread with Smjör (Icelandic butter).
• Cod specialities: Cheeks (kinnar) and the fleshy muscles (“cod tongues”) known as gellur are often pan-fried or prepared in other simple ways.
• Salted cod: Salted and dried cod (“saltfiskur”, “bacalao”) is usually soaked and boiled and eaten with boiled potatoes and butter or used in making fish stew.
