Osmeridae (Smelts)
Etymology: Mallotus: Greek for fleecy, derived from mallos = wool, and -otus = a Greek adjectival suffix referring to property; referring to the shape of the scales along the side of breeding males, appearing hairy or fleecy (S.Kullander, pers. Comm.).
Environment: milieu / climate zone / depth range / distribution range

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 10 - 14; Anale stekels: 0; Anale zachte stralen: 16 - 23; Wervels: 62 - 73. Adipose with long base, about 1.5 times as long as the orbit or longer, outer margin only slightly curved (Ref. 6885). Olive green on dorsal surface, merging into silvery on sides and ventral surface (Ref. 6885).
Oceanic species found in schools (Ref. 2850). Nerito-pelagic (Ref. 58426); however, reported at 1086 m Davis Strait to southern Baffin Bay (Ref. 120413). Adults feed on planktonic crustaceans, copepods, euphausiids, amphipods, marine worms, and small fishes (Ref. 6885, 35388). Mature individuals move inshore in large schools to spawn (Ref. 2850). In the spring large spawning shoals migrate toward the coasts, males usually arrive first. Often entering brackish and freshwater (Ref. 37812). Semelparous (Ref. 51846). Produces 6,000-12,000 adhesive eggs. Females are valued for their roe, males are utilized as fishmeal. Marketed canned and frozen; eaten fried and dried (Ref. 9988). Possibly to 725 m depth (Ref. 6793).
Reproductive strategy: synchronous ovarian organization, determinate fecundity (Ref. 51846). Experimental testing suggests facultative semelparity, with offshore-spawning capelin being absolute semelparous (death of both genders) and beach-spawning capelin being iteroparous irrespective of sex (Ref. 92136). Also Ref. 92150.
