Herring is an oily fish of the genus Clupea, found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea.[2] Two species of Clupea are recognized, the Atlantic herring (Clupea harengus) and the Pacific herring (Clupea pallasii), each which may be divided into subspecies. Herrings are forage fish moving in vast schools, coming in spring to the shores of Europe and America, where they are caught, salted and smoked.

[edit] Morphology
The two species of Clupea belong to the larger family Clupeidae (herrings, shads, sardines, menhadens), which comprise some 200 species, which all share similar features. They are silvery colored fish that have a single dorsal fin, which is soft, without spines. They have no lateral line and have a protruding lower jaw. Their size varies between subspecies: the Baltic herring (Clupea harengus membras) is small, 14 to 18 centimeters, the proper Atlantic herring (C. h. harengus) can grow to about 46 cm (18 inches) and weigh up 700 g (1.5 pounds), and Pacific herring grow to about 38 cm (15 inches).
[edit] Predators
Predators of herring include humans, seabirds, dolphins, porpoises, striped bass, seals, sea lions, whales. Sharks, dog fish, tuna, cod, salmon, halibut and other large fish also feed on adult herring.
[edit] Diet
See Atlantic herring for videos of feeding juvenile herring, catching copepods.
Young herring feed on phytoplankton and as they mature they start to consume larger organisms. Adult herring feed on zooplankton, tiny animals that are found in oceanic surface waters, and small fish and fish larvae. Copepods and other tiny crustaceans are the most common zooplankton eaten by herring. During daylight herring stay in the safety of deep water, feeding at the surface only at night when there is less chance of predation. They swim along with their mouths open, filtering the plankton from the water as it passes through their gills.
[edit] Economy
Adult herring are harvested for their meat and eggs, and they are often used as baitfish. The trade in herring is an important sector of many national economies. In Europe the fish has been called the "silver of the sea", and its trade has been so significant to many countries that it has been regarded as the most commercially important fishery in history.[3]
Environmental Defense have suggested that Atlantic herring (Clupea harengus) are one of the more environmentally responsible fish.[4]
[edit] Cuisine
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. The fish was sometimes known as "two-eyed steak".
[edit] Nutrition
Herring are very high in the long-chain Omega-3 fatty acids EPA and DHA.[5] They are a source of vitamin D.
Large Baltic herring slightly exceeds recommended limits with respect to PCB and dioxin, although some sources point out that cancer-reducing effect of omega-3 fatty acids is statistically stronger than the cancer-causing effect of PCBs and dioxins,[6]. The contaminant levels depend on the age of the fish which can be inferred from their size. Baltic herrings larger than 17 cm may be eaten twice a month, while herrings smaller than 17 cm can be eaten freely.[7]
[edit] Pickled herring
Pickled herring is a delicacy in Europe, and has become a part of Baltic, Scandinavian, German, Eastern Slavic and Jewish cuisine. Most cured herring uses a two-step curing process. Initially, herring is cured with salt to extract water. The second stage involves removing the salt and adding flavorings, typically a vinegar, salt, sugar solution to which ingredients like peppercorn, bay leaves and raw onions are added. In recent years also other flavors have been added due to foreign influences. However, the tradition is strong in Denmark, Sweden and Germany. Onion, sherry, mustard and dill are some of the traditional flavourings. Very small quantities of the exotic flavourings are sold. An overwhelming majority of Scandinavians prefer the traditional flavourings.[citation needed]
In Scandinavia and Germany, once the pickling process is finished and depending on which of the dozens of classic herring flavourings (mustard, onion, garlic, lingonberries etc.) are selected, it is eaten with dark rye bread, crisp bread, sour cream, or potatoes. This dish is common at Christmas, Easter and Midsummer, where it is eaten with akvavit (Scandinavian schnapps).
In the 19th century, people in Berlin developed a special treat known in English as soused herring or rollmops.[8][9]
Pickled herring is common in Russian cuisine, where it can be served as simple as just cut into pieces seasoned with sunflower oil and onions, or can be part of herring salads, which are usually prepared with vegetables and seasoned with mayonnaise dressing.[10]
Pickled herrings are common in Ashkenazi Jewish cuisine, perhaps best known for forshmak salad known in English simply as "chopped herring". In Poland it is known as "śledzie".
Pickled herring can also be found in the cuisine of Hokkaidō in Japan, where families traditionally preserved large quantities for winter.
Rollmops are pickled herring fillets rolled (hence the name) into a cylindrical shape around a piece of pickled gherkin or an onion. The word is borrowed from the German.
[edit] Fermented
In Sweden, Baltic herring ("Strömming") is fermented to make surströmming.
[edit] 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 first barrel of Hollandse Nieuwe is traditionally sold at auction for charity.
Herring is also canned and exported by many countries. A sild is an immature herring that is canned as sardines in Iceland, Sweden, Norway or Denmark.[citation needed]
[edit] Dried
In the Philippines, dried herring is popularly eaten during breakfast, along with garlic rice and eggs.
Very young herring are called whitebait and are eaten whole as a delicacy.
[edit] Other means
In Scotland the herring is traditionally filleted and after being coated in seasoned pin-head oatmeal is fried in a pan with butter or oil. This dish is usually served with "crushed" buttered boiled potatoes. A kipper is a split and smoked herring, a bloater is a whole smoked herring and a buckling is a hot smoked herring with the guts removed. All are staples of British cuisine. According to George Orwell in The Road to Wigan Pier, the Emperor Charles V erected a statue to the inventor of bloaters.
Smoked herring is a traditional meal on the Danish island in the Baltic Sea, Bornholm. This is also the case in Sweden where one can get hard fried/smoked "Strömming" named "Sotare" in places like Skansen, Stockholm. In Sweden, herring soup is also 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.
