Perforated containers for shark maturation
Movable perforated containers hold Greenland-shark cuts during the modern Icelandic maturation of hákarl, letting liquid drain; the best-documented example is a wooden box used in a 2021 study.

Herring salting barrel
wooden herring barrel · herring-curing barrel
A coopered wooden barrel held herring and salt during northern European curing. Siglufjörður's early-20th-century station is one documented setting; barrel forms and processes varied.
A coopered barrel for salted fish
A herring salting barrel is a coopered wooden vessel assembled from shaped staves and held together by hoops, with fitted heads that close the ends. A 1792 harbor-side print by S. Vdr. Meulen depicts herring packing beside open upright barrels; it gives a direct visual record of the vessel's historical form in use, though it is an illustration rather than a technical drawing. The archive record does not identify the harbor, so it cannot place this barrel form in Iceland.
In use, the barrel could hold fish and salt together as contents settled and brine accumulated. Barrels made a substantial catch easier to store, move from shore and send to markets. The sources do not establish one standard capacity, timber species, hoop material or stave profile. The print cannot identify the maker or every material detail. The form shown here is a coopered herring barrel, not a large upright fermentation vat or a modern plastic tub.
The Icelandic station at Siglufjörður
At Siglufjörður in northern Iceland, Róaldsbrakki is a former salting station built in 1907. The Herring Era Museum now preserves the building and interprets the industrial fishery and processing work that shaped the town. Fjallabyggð describes dockside demonstrations in which herring is gutted and packed in barrels to recreate part of the historical working scene.
A contemporary demonstration is not a photograph of the original operation. It shows how the museum presents the task today, while the preserved station anchors the setting in the early-twentieth-century Icelandic herring industry. It does not prove that every barrel had the same profile, volume or construction.

Layers, salt and brine
The atlas describes open barrels packed with fish in ordered layers with salt, then covered. Keeping herring and salt together made the barrel useful for curing, storage and transport. A barrel’s opening also allowed workers to add fish or adjust the contents before closing it, but the sources do not provide a universal pack order or fixed amount of salt for this equipment entry.
A 1905 photograph in the Scottish Fisheries Museum archive shows a fisher girl topping up a barrel with brine. Its caption says that after ten days the barrels were topped up through a hole in the side. That is useful comparative evidence for barrel handling in North East Scotland; it is not a schedule or instruction for the Icelandic station.
Salted herring is not always fermented herring
The barrel is equipment, not a process label. Northern European barrel-salted herring could be salted and ripened, while products such as Swedish surströmming follow a distinct fermentation tradition. The review by Skåra and colleagues treats barrel-salted ripened herring across the region and discusses surströmming separately. A barrel photograph on its own therefore cannot tell a reader whether a batch was intended for ordinary salting, longer ripening or a specific fermented product.
The page links the vessel to the preparation record for salted herring because the archive describes layered herring and salt in open wooden barrels. This records a supported equipment relationship; it does not make the barrel exclusive to one recipe or imply that every herring cure is fermented.

History
A 1792 print by S. Vdr. Meulen depicts open upright barrels and a barrel on its side in a harbor-side herring-packing scene; its archive record does not name the harbor. It is an early attestation of use, not an origin claim or evidence that the pictured barrels were used in Iceland. Róaldsbrakki at Siglufjörður is a later documented station built in 1907; Scottish museum images provide separate early-twentieth-century comparison.
Equipment details
CapacityNo barrel capacity is established for the documented Icelandic station or the 1905 Scottish image.
SizeThe cited sources do not give a barrel size; dimensions varied by trade and period.
PowerNo power The barrel is an unpowered vessel; salting and brine handling were manual.
How you get oneNot established The sources document historical and museum use, not a current maker or a standard barrel for purchase.
CareThe sources describe historical salting barrels and museum demonstrations; they do not give current cleaning, maintenance or food-safety instructions.
Made of
- Wood — Staves forming the barrel body and heads
The source documents a coopered wooden barrel form; it does not identify a standard species for the Icelandic salting barrels. - Hoops — Hold the staves together
Hoops are visible features of the barrel form; the cited sources do not establish one material or pattern for every barrel.
Limits
A photograph of a barrel does not establish one standard shape, capacity, stave species or hoop material.
Source →The Scottish archive image is a comparison from North East Scotland, not proof that its pictured brine-topping schedule was used in Iceland.
Source →Barrel-salted herring and fermented herring products are not interchangeable; the vessel alone does not establish the process or degree of fermentation.
