Clupeidae (Herrings, shads, sardines, menhadens)
Etymology: Sprattus: Old German, sprotte (1611) = a small fish, Clupea sp. (Ref. 45335).
More on author: Linnaeus.
Taxonomic Remarks
The subspecies were not characterized well enough, that unless there is more evidence presented in the future, Sprattus sprattus should be considered as one species with several known populations (S.Kullander, pers.comm. 07/09).

Usually inshore schooling, sometimes entering estuaries (especially the juveniles) and tolerating salinities as low as 4 ppt. Shows strong migrations between winter feeding and summer spawning grounds. Moves to the surface at night. Feeds on planktonic crustaceans (Ref. 9900). Spawns at depths of 10-20 m producing 6,000-14,000 pelagic eggs (Ref. 35388). Some spawn almost throughout the year, mainly in spring and summer, near the coast or up to 100 km out to sea, the young drifting inshore. Sold as 'brislings' to canneries. Sprat are used in the production of fish meal and as mink food, less for human consumption (Ref. 9900). Utilized fresh, smoked, canned and frozen; can be pan-fried and broiled (Ref. 9988).
Some spawn almost year round but mainly in spring and summer, near to the coast or up to 100 km out to sea, the young drifting inshore. Individual period of spawning takes about two months (Ref. 92054).
