Overview

Clupeinae is a subfamily of small, oily, schooling fish within the family Clupeidae. It includes herring, sardines, and sprats, all characterized by a single dorsal fin, a forked tail, and a laterally compressed body covered in large, silvery scales. These fish are prized for their rich, oily flesh and are consumed fresh, cured, smoked, or canned across virtually every coastal cuisine.

Origin and history

Clupeinae species are found in temperate and tropical waters worldwide, with major fisheries in the North Atlantic, North Pacific, and Mediterranean. Herring (genus Clupea) has been a staple of Northern European diets. Sardines (genera Sardina and Sardinops) take their name from the Italian island of Sardinia, where large fisheries operated by the 15th century [2]. Sprats (genus Sprattus) are closely related and are often processed similarly, particularly in the Baltic and Black Seas. The canning of sardines in oil was perfected in early 19th-century France, notably in Nantes, and spread globally as a method of preserving the highly perishable catch [3].

Varieties and aliases

  • Atlantic herring (Clupea harengus): The dominant herring species in the North Atlantic.
  • Pacific herring (Clupea pallasii): Found in the North Pacific; also harvested for roe (kazunoko).
  • European pilchard (Sardina pilchardus): The true sardine of the Mediterranean and Eastern Atlantic.
  • Pacific sardine (Sardinops sagax): Also called pilchard; found in the Pacific and Indian Oceans.
  • European sprat (Sprattus sprattus): Also called bristling; common in the Baltic.
  • Japanese sardine (Sardinops melanostictus): A key species in Japanese cuisine.
  • Sardine is a general term often applied to any small Clupeinae fish canned in oil, regardless of species.

Culinary uses

Clupeinae fish are prepared in a wide range of ways. Fresh sardines are grilled, fried, or baked, often with little more than salt, lemon, and herbs. Herring is commonly pickled in vinegar or brine (rollmops, soused herring), salted and dried (salt herring, surströmming), or smoked (kippers, bloaters). Sprats are frequently smoked and canned in oil or tomato sauce. In Japan, ma-iwashi (sardine) is grilled, simmered in soy-based sauces, or dried as niboshi for dashi stock. The high oil content of these fish makes them well suited to preservation by salting, smoking, and canning [3].

Notes for cooks

  • Fresh sardines and herring are highly perishable. Look for bright, clear eyes, firm flesh, and a clean sea smell. Any fishy or ammonia odor indicates spoilage.
  • The small bones in Clupeinae fish are edible when cooked, especially in canned or fried preparations. For pickled herring, the bones soften during the curing process.
  • Substitution: In most recipes, sardines and herring can be used interchangeably, though herring is generally larger and firmer. Sprats are smaller and more delicate.
