The capelin or caplin (Mallotus villosus) is a small forage fish of the smelt family found in the North Atlantic, North Pacific and Arctic oceans. In summer, it grazes on dense swarms of plankton at the edge of the ice shelf. Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid and seabirds prey on capelin, in particular during the spawning season of the capelin while it migrates southwards. Capelin spawn on sand and gravel bottoms or sandy beaches at the age of 2–6 years, and have an extremely high mortality rate on the beaches after spawning, for males close to 100%. Males reach 20 cm (8 in) in length, while females are up to 25.2 cm (10 in) long. They are olive-colored dorsally, shading to silver on sides. Males have a translucent ridge on both sides of their bodies. The ventral aspects of the males iridesce reddish at the time of spawn.

Capelin migration

Capelin Capelin Calendar newfoundsander

Capelin in the Barents Sea and around Iceland are stocks that perform extensive seasonal migrations. Barents Sea capelin migrate during winter and early spring to the coast of northern Norway (Finnmark) and the Kola Peninsula (Russia) for spawning. During summer and autumn capelin migrate north- and north-eastward for feeding.

Icelandic capelin move inshore in large schools to spawn and migrate in spring and summer to feed in the plankton-rich oceanic area between Iceland, Greenland, and Jan Mayen. Capelin distribution and migration is linked with ocean currents and water masses. Around Iceland, maturing capelin usually undertake extensive northward feeding migrations in spring and summer and the return migration takes place in September to November. The spawning migration starts from north of Iceland in December to January. In a paper published in 2009, researchers from Iceland recounted their application of an interacting particle model to the capelin stock around Iceland, successfully predicting the spawning migration route for 2008.


As an r-selected species, capelin have a high reproductive potential and an intrinsic population growth rate. They reproduce by spawning and their main spawning season occurs in spring, but can extend into the summer. The majority of capelin are three or four years old when they spawn. The males migrate directly to the shallow water of fjords, where spawning will take place, while the females remain in deeper water until they are completely mature. Once the females are mature, they will migrate to the spawning grounds and spawn. This process usually takes place at night. In the North European Atlantic spawning typically occurs over sand or gravel at depths of 2 to 100 m (7–328 ft), but in the North Pacific and waters off Newfoundland most spawn on beaches, jumping as far up land as possible, with some managing to strand themselves in the process. Although some other fish species leave their eggs in locations that dry out (a few, such as plainfin midshipman, may even remain on land with the eggs during low tide) or on plants above the water (splash tetras), jumping onto land en masse to spawn is unique to the capelin, grunions and grass puffer. After the female capelins have spawned, they immediately leave the spawning grounds and will potentially spawn again in the following years if they survive. The males do not leave the spawning grounds and will potentially spawn more than once throughout the season. Male capelin are considered to be semelparous because they die soon after the spawning season is over.

Capelin is an important forage fish, and is essential as the key food of the Atlantic cod. The northeast Atlantic cod and capelin fisheries therefore are managed by a multispecies approach developed by the main resource owners Norway and Russia.

In some years with large quantities of Atlantic herring in the Barents Sea, capelin seem to be heavily affected. Probably both food competition and herring feeding on capelin larvae lead to collapses in the capelin stock. However, in some years there has been good recruitment of capelin despite a high herring biomass, suggesting that herring are only one factor influencing capelin dynamics.

In the provinces of Quebec (particularly in the Gaspé peninsula) and Newfoundland and Labrador in Canada, it is a regular summertime practice for locals to go to the beach and scoop the capelin up in nets or whatever is available, as the capelin "roll in" in the millions each year at the end of May or in early June.

Commercially, capelin is used for fish meal and oil industry products, but is also appreciated as food. The flesh is agreeable in flavor, resembling herring. Capelin roe ("masago") is considered a high-value product. It is also sometimes mixed with wasabi or green food coloring and wasabi flavor and sold as "wasabi caviar". Often, masago is commercialized as ebiko and used as a substitute for tobiko, flying fish roe, owing to its similar appearance and taste —although the mouthfeel is different due to the individual eggs being smaller and less crunchy than tobiko.
