What Is a Group of Herrings Called?

Cran is the term most closely tied to herrings, and unlike most collective animal nouns, it didn’t start as a poetic flourish, it started as a unit of trade. Glean is a rarer, more regional term that turns up occasionally in older fishing writing. Shoal is the general fish-grouping word that applies to herrings just as it does to countless other species, describing the loose, drifting gatherings they form. Army is the most dramatic of the four, evoking the sheer scale of a herring gathering large enough to blot out the water beneath a boat.

Where Did the Name Come From?

Most English collective nouns for animals trace back to medieval hunting terminology, particularly the Book of Saint Albans (1486), but “cran” has a very different, and much more concrete, history. A cran was a genuine standard measure used in the British and Scottish herring trade, roughly 37.5 gallons of fresh fish, used at ports to gauge and price a boat’s catch before it went to market or the curing sheds. Over time the measurement itself became shorthand for the mass of fish it described. “Glean,” “shoal,” and “army,” by contrast, sit closer to the older, more descriptive tradition of animal-grouping words, chosen for how a herring gathering looks and behaves rather than how it was sold by the barrel.

Herring Facts

• Enormous schools: Herrings form some of the densest schools of any fish, sometimes stretching for miles and visible on sonar as a single moving mass.
• An economic backbone: For centuries herring fisheries shaped entire coastal economies in Northern Europe and the North Atlantic, earning herring the nickname “silver of the sea.”
• Filter feeders: Herrings feed mainly on zooplankton, including copepods and other tiny crustaceans, straining them from the water as they swim.
• Cold-water range: Atlantic herring (Clupea harengus) and Pacific herring (Clupea pallasii) are found in cold, temperate coastal waters on either side of the globe.
• Long-lived for their size: Despite their small size, herrings can live well over a decade, with some northern populations reaching 15 to 20 years.
• Talking in the dark: Researchers have documented herrings producing bursts of clicking sound at night, a behavior some scientists suspect helps keep large schools coordinated after sundown.

Example Sentences

• The trawler’s sonar lit up as a cran of herring surged beneath the hull, dense enough to look like solid seafloor.
• Coastal fishing logs once described an army of herring arriving each autumn as a sign the season’s catch was secured.

Other Names for a Group of Herrings

Cran remains the term most specifically and historically tied to herrings, thanks to its roots in the fishing trade itself rather than in folklore. Shoal is by far the most commonly used word today, since it’s the standard general term for schooling fish and needs no special context to be understood. Army shows up in older or more colorful writing, emphasizing scale and spectacle, while glean is the rarest of the four, largely confined to historical or regional usage.
