# Herring as food

Herring are forage fish in the wild, mostly belonging to the family Clupeidae. They are an important food for humans. Herring often move in large schools around fishing banks and near the coast. The most abundant and commercially important species belong to the genus Clupea, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of Clupea are recognized; the main taxon, the Atlantic herring, accounts for over half the world's commercial capture of herrings.
Herrings played a pivotal role in the history of marine fisheries in Europe, and early in the twentieth century, their study was fundamental to the evolution of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled.

## Nutrition

Raw Atlantic herring is 72% water, 18% protein, 9% fat, and contains no carbohydrates. In a 100 gram reference amount, raw herring provides 158 calories, and is a highly rich source (20% or more of the Daily Value, DV) of vitamin B$_{12}$ (570% DV). It also has rich content of niacin, vitamin B$_6$, vitamin D, and phosphorus (21-34% DV). Raw herring contains moderate amounts of other B vitamins and zinc, and is an excellent food source of omega-3 fatty acids.

### Contamination

Pacific and Atlantic herring are susceptible to contamination from environmental pollution, such as by PCBs, PBDEs, mercury, and listeria. There is a (rare) risk of harmful bacteria from eating raw herring eggs.

## Preparation

Herring has been a staple food source since at least 3000 B.C. There are numerous ways the fish is served and many regional recipes: eaten raw, fermented, pickled, or cured by other techniques.

### Raw

A typical Dutch delicacy is Hollandse Nieuwe (Dutch New), which is raw herring from the catches around the end of spring and the beginning of summer. This is typically eaten with raw onion. Hollandse nieuwe is only available in spring when the first seasonal catch of herring is brought in. This is celebrated in festivals such as the Vlaardingen Herring Festival and Vlaggetjesdag in Scheveningen. The new herring are frozen and enzyme-preserved for the remainder of the year. The herring is said to be eaten "raw" because it has not been cooked, although it has been subjected to a degree of curing. The first barrel of Hollandse Nieuwe is traditionally sold at auction for charity. Very young herring are called whitebait and are eaten whole as a delicacy.

### Salted

In Norway, salting herring is a significant business. Herring was traditionally salted in wooden barrels and constituted a significant food resource. Salted herring is the basis for a number of herring dishes, as spekesild.

### Fermented

In Sweden, Baltic herring ("Strömming") is fermented to make surströmming.

### Pickled

Pickled herrings are part of German (Bismarckhering), Nordic, British, Canadian, Dutch, Polish, Baltic and Jewish cuisine. Most herring cures use a two-step process. Initially, the herrings are cured with salt to extract water. The second stage involves removing the salt and adding flavorings, typically a vinegar, salt, and sugar solution to which ingredients like peppercorn, bay leaves and raw onions are added. Other flavors can be added, such as sherry, mustard and dill. The tradition is strong in Scandinavia, the Netherlands, Poland, Iceland and Germany.

### Dried

In the Philippines, dried herring is popularly eaten during breakfast, along with garlic rice and eggs.

### Smoked

A kipper is a split, gutted and cold-smoked herring, a bloater is a whole non-gutted cold smoked herring, and a buckling is a whole herring, gutted apart from roe or milt and then hot-smoked. All are staples of British cuisine. According to George Orwell in The Road to Wigan Pier, Emperor Charles V erected a statue to the inventor of bloaters.
Smoked herring is a traditional meal on Bornholm. This is also the case in Sweden, where one can get hard-fried/smoked strömming, known as sotare, in places like Skansen, Stockholm.

### Other

In Scotland, herrings are traditionally filleted, coated in seasoned pin-head oatmeal, and fried in a pan with butter or oil. This dish is usually served with "crushed", buttered, and boiled potatoes.
In Sweden, herring soup is a traditional dish.
In Southeast Alaska, western hemlock boughs are cut and placed in the ocean before the herring arrive to spawn. The fertilized herring eggs stick to the boughs, and are easily collected. After being boiled briefly the eggs are removed from the bough. Herring eggs collected in this way are eaten plain or in herring egg salad. This method of collection is part of Tlingit tradition.

## Foods and dishes

| Name | Origin | Description |
| Avruga caviar | Spain | Avruga is marketed by the Spanish company Pescaviar as a caviar substitute. It is made from herring (40%), salt, corn starch, lemon juice, citric acid, xanthan gum, sodium benzoate, squid ink and water. Unlike caviar, it does not contain fish roe. |
| Bloater | England | Popular in the 19th and early 20th centuries, bloaters are now rare. They can be contrasted with kippers. Kippers are salted and cold-smoked overnight while bloaters are salted less and not smoked for so long. Kippers are split and gutted before smoking while bloaters are smoked whole without gutting. Kippers are associated with Scotland while bloaters are associated with England. Bloaters have their own characteristic slightly gamey flavor and are called "bloaters" because they swell or bloat during preparation. |
| Brathering | Germany | A dish of fried marinated herring. A common recipe starts with fresh herrings with the head and gut removed that are breaded or turned in flour, fried and then pickled in a marinade of vinegar. The pickled herrings are then boiled briefly in water containing onion, salt, spices like pepper, bay leaves, mustard seeds, and a little sugar. The herring are served cold with bread and fried or jacket potatoes. |
| Buckling | European | A hot-smoked herring similar to a kipper or bloater. The guts are removed but the roe or milt remain. Buckling is hot-smoked whole, as opposed to kippers which are split and gutted, and then cold smoked. Bucklings can be eaten hot or cold. |
| Dressed herring | Russia | A layered salad of diced salted herring covered with alternating layers of grated boiled vegetables (potato, carrot and beet root) and chopped onions. Optionally includes a layer of fresh grated apple. The final layer is beet root covered with mayonnaise, which gives the salad a rich purple color. Often decorated with grated boiled eggs. Popular in Russia and other countries of the former USSR, where it is traditional at New Year and Christmas celebrations. Also known as herring under a fur coat or just fur coat. |
| Fischbrötchen (lit. fish sandwich) | Germany | A sandwich or roll made with fish and onions, sometimes also made with remoulade and pickles. Most commonly made with bismarck herring or soused herring, and eaten in Northern Germany, due to the region's proximity to the North Sea and Baltic Sea. |
