The European sprat (Sprattus sprattus), also known as brisling, brisling sardine, bristling, garvie, garvock, Russian sardine, russlet, skipper or whitebait, is a species of small marine fish in the herring family Clupeidae. [3] Found in European, West Asian and North African waters, it has silver grey scales and white-grey flesh. Specific seas in which the species occurs include the Irish Sea, Black Sea, Baltic Sea and Sea of the Hebrides. [4] The fish is the subject of fisheries, particularly in Scandinavia, and is made into fish meal, as well as being used for human consumption. When used for food it can be canned, salted, breaded, fried, boiled, grilled, baked, deep fried, marinated, broiled, and smoked.
This fish was first described by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae. He called it Clupea sprattus, but it was later transferred to the genus Sprattus . [2] Three subspecies are recognised; S. sprattus balticus from the Baltic Sea; S. sprattus phalericus from the Mediterranean, Adriatic and Black Seas and S. sprattus sprattus from the eastern Atlantic. [5]
The European sprat is a small fish growing to a maximum length of 16 cm (6.3 in), but more often in the 8 to 12 cm (3 to 5 in) range. It is fairly elongate and somewhat laterally compressed, with a keel-like row of sharp scales along the belly. The lower jaw projects slightly, there are seldom any vomerine teeth on the roof of the mouth and the hind edge of the gill covers is smoothly rounded, without any fleshy protuberances. The dorsal fin has no spines and 13 to 21 soft rays while the anal fin has no spines and 12 to 23 soft rays. The origin of the pelvic fins, which have seven (occasionally eight) soft rays, are immediately below or in front of the origin of the dorsal fin. This fish has a bluish or greenish back and silvery flanks, with no dark spotting. [5] [6]
The European sprat is native to the northeastern Atlantic Ocean. Its range includes the Baltic Sea, the North Sea, southern Norway and Sweden, round the coasts of the British Isles, the Iberian Peninsula, Morocco, the Mediterranean Sea, the Adriatic Sea and the Black Sea. It occurs both in open water well away from the coast and in bays and estuaries, being able to tolerate salinities as low as 4 parts per thousand. It is a schooling fish and migrates between its winter feeding grounds and its summer breeding grounds. It also makes vertical migrations, rising to near the surface at night to feed. [7]
Adult sprats feed on copepods such as Calanus , Pseudocalanus and Temora while juveniles feed on the eggs and larvae of these crustaceans, and on diatoms. Breeding takes place at any time of year but peaks between December and April in the Mediterranean and between April and August in the Baltic and northeastern Atlantic. Spawning may take place in inshore waters or up to 100 km (60 mi) off the coast. [5]
This fish is sometimes parasitised by a copepod, the sprat eye-maggot (Lernaeenicus sprattae) which burrows into its eye and causes loss of visual acuity or even blindness. Heavy infestations can kill the fish.[ citation needed ]
There are substantial fisheries for this fish in various parts of its range. It is mostly caught by trawling and is made into fish meal, canned, smoked, and eaten fresh; cooking methods include pan-frying and broiling. It is used for feeding mink and juveniles are used for fish bait. [3] Young sprats are commonly known as brisling. Canned sprats (usually smoked) are available in many north European countries, including the Baltic states, Scandinavia, Ireland, Germany, Poland and Russia. The fish has about 10.5% fat in its flesh and is a rich source of vitamins and minerals. [8]
This fish has large swings in its population size, particularly in the Mediterranean Sea and Black Sea. These may in part be due to the increasing dominance of the comb jelly Mnemiopsis leidyi which in turn may be related to increases in sea temperature[ citation needed ]. Landings by commercial fisheries in the Mediterranean and Black Seas fell in the 1990s but recovered in the next decade. The population size and trend of this fish is unknown and the International Union for Conservation of Nature is unable to assess its conservation status, listing it as "Data deficient". [3]

Cod is the common name for the demersal fish genus Gadus, belonging to the family Gadidae. Cod is also used as part of the common name for a number of other fish species, and one species that belongs to genus Gadus is commonly not called cod.
Herring are forage fish, mostly belonging to the family of Clupeidae.
Atlantic herring is a herring in the family Clupeidae. It is one of the most abundant fish species in the world. Atlantic herrings can be found on both sides of the Atlantic Ocean, congregating in large schools. They can grow up to 45 centimetres (18 in) in length and weigh up to 1.1 kilograms (2.4 lb). They feed on copepods, krill and small fish, while their natural predators are seals, whales, cod and other larger fish.
Sprat is the common name applied to a group of forage fish belonging to the genus Sprattus in the family Clupeidae. The term also is applied to a number of other small sprat-like forage fish. Like most forage fishes, sprats are highly active, small, oily fish. They travel in large schools with other fish and swim continuously throughout the day.
Merlangius merlangus, commonly known as whiting or merling, is an important food fish in the eastern North Atlantic Ocean and the northern Mediterranean, western Baltic, and Black Sea. In Anglophonic countries outside the Whiting's natural range, the name "whiting" has been applied to various other species of fish.
The Atlantic horse mackerel, also known as the European horse mackerel or common scad, is a species of jack mackerel in the family Carangidae, which includes the jacks, pompanos and trevallies. It is found in the eastern Atlantic Ocean off Europe and Africa and into the south-eastern Indian Ocean. It is an important species in commercial fisheries and is listed as a Vulnerable species on The IUCN Red List of Threatened Species.
The school shark is a houndshark of the family Triakidae, and the only member of the genus Galeorhinus. Common names also include tope, tope shark, snapper shark, and soupfin shark. It is found worldwide in temperate seas at depths down to about 800 m (2,600 ft). It can grow to nearly 2 m long. It feeds both in midwater and near the seabed, and its reproduction is ovoviviparous. This shark is caught in fisheries for its flesh, its fins, and its liver, which has a very high vitamin A content. The IUCN has classified this species as critically endangered in its Red List of Threatened Species.

The Australian sprat is a sprat fish whose habitat ranges in the waters surrounding Australia including Tasmania. It is a pelagic fish which is found in anti-tropical, temperate water. It is a part of the Clupeidae family. Other members of the Cluepeidae family also include herring, menhaden, sardines as well as shads. It is currently a relative unknown species of Sprat compared to the other members of the family. In total, there are five different types of True Sprats. What makes Australian Sprats different from the rest is their location and appearance. Sprattus Novaehollandiae have a dark blue back and a protruding lower jaw. They are found in the Southern regions of Australian such as lower Victoria and Tasmania were there are colder climates. On average, Australian Sprat grown up to 14 cm and live in the range of 0–50 meters deep in the ocean. They will lay between 10,000 and 40,000 eggs per year and live for approximately 5–7 years. Other names for the Australian Sprat include Clupea Bassensis and Meletta Novaehollandiae.
The common ling, also known as the white ling or simply the ling, is a large member of the family Lotidae, a group of cod-like fishes. It resembles the related rocklings, but it is much larger and has a single barbel. This species is unrelated to the pink ling, Genypterus blacodes, from the Southern Hemisphere. The common ling is found in the northern Atlantic, mainly off Europe, and into the Mediterranean Basin. It is an important quarry species for fisheries, especially in the northeastern Atlantic, although some doubts exist as to the sustainability of the fisheries. As an edible species, it is eaten fresh, frozen, or dried, but also preserved in lye, while the roe is a delicacy in Spain.
Mullus barbatus is a species of goatfish found in the Mediterranean Sea, Sea of Marmara, the Black Sea and the eastern North Atlantic Ocean, where its range extends from Scandinavia to Senegal. They are fished, mostly by trawling, with the flesh being well regarded. The International Union for Conservation of Nature has assessed their conservation status as being of "least concern".
The European flounder is a flatfish of European coastal waters from the White Sea in the north to the Mediterranean and the Black Sea in the south. It has been introduced into the United States and Canada accidentally through transport in ballast water. It is caught and used for human consumption.
The European anchovy is a forage fish somewhat related to the herring. It is a type of anchovy; anchovies are placed in the family Engraulidae. It lives off the coasts of Europe and Africa, including in the Mediterranean Sea, the Black Sea, and the Sea of Azov. It is fished by humans throughout much of its range.
Chromis chromis, the damselfish or Mediterranean chromis, is a small species of ray-finned fish of the family Pomacentridae from the Eastern Atlantic and Mediterranean.
The European pilchard is a species of ray-finned fish in the monotypic genus Sardina. The young of the species are among the many fish that are sometimes called sardines. This common species is found in the northeast Atlantic, the Mediterranean, and the Black Sea at depths of 10–100 m (33–328 ft). It reaches up to 27.5 cm (10.8 in) in length and mostly feeds on planktonic crustaceans. This schooling species is a batch spawner where each female lays 50,000–60,000 eggs.
Merluccius merluccius, the European hake, is a merluccid hake of the genus Merluccius. Other vernacular names include Cornish salmon and herring hake. It is a predatory species which was often netted alongside one of its favoured prey, the Atlantic herring, thus the latter common name. It is found in the eastern Atlantic from the Norway and Iceland south to Mauritania and into the Mediterranean Sea. It is an important species in European fisheries and is heavily exploited with some populations thought to be being fished unsustainably.
Clupea is genus of planktivorous bony fish belonging to the family Clupeidae, commonly known as herrings. They are found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea. Two main species of Clupea are currently recognized: the Atlantic herring and the Pacific herring, which have each been divided into subspecies. Herrings are forage fish moving in vast schools, coming in spring to the shores of Europe and America, where they form important commercial fisheries.
Sardines ("pilchards") are a nutrient-rich, small, oily fish widely consumed by humans and as forage fish by larger fish species, seabirds and marine mammals. Sardines are a source of omega-3 fatty acids. Sardines are often served in cans, but can also be eaten grilled, pickled, or smoked when fresh.
