Livestock[edit] The raising of livestock, sheep (the traditional mainstay for generations of Icelandic farmers) and cattle (the latter grew rapidly in the 20th century), is the main occupation, but pigs and poultry are also reared; Iceland is self-sufficient in the production of meat, dairy products and eggs.

Icelanders eat mostly haddock, plaice, halibut, herring, and shrimp.ther local ingredients that form part of the Icelandic chef's store include seabirds and waterfowl (including their eggs), salmon and trout, crowberry, blueberry, rhubarb, Iceland moss, wild mushrooms, wild thyme, lovage, angelica and dried seaweed as well as a wide array of dairy products.
