Comments: Ranges from the Pacific to Atlantic coasts through the Canadian Arctic (Ref. 58426). Originally ranged in the Atlantic coastal drainage, from Labrador southward. Landlocked populations occur in inland waters of New Brunswick, Nova Scotia, insular New Foundland, Labrador, Quebec, and eastern Ontario. Occurs in the Great Lakes (Ref. 119192). Introduced into Lake Superior in the early 1930s. Reached commercially harvestable levels by 1952 and eventually replaced lake herring as the dominant planktivore. In 1970, its decline led to the increase in lake herring population (Ref. 9041). Major fishery in New Brunswick. In Lake Erie, large catches mainly taken with otter trawls. The Atlantic smelt commands a high price and are sold whole or in the round. The Great Lakes smelt are usually mechanically processed and sold fresh, frozen, and precooked. Some stockes have also been introduced (Ref. 74657). Also Ref. 6793, 7251, 85409, 86798, 96339, 119194. Status of threat of New Brunswick dwarf population in Lake Utopia: threatened; status declined since 1989. Criteria: 5 (http://fisc.er.usgs.gov/afs/) (Ref. 81264).

Sinh học     Tự điển (thí dụ epibenthic)

Nerito-pelagic (Ref. 58426). Inhabits cool clear lakes, medium to large rivers, and coastal waters (Ref. 86798). A schooling species that occurs in midwater of lakes or inshore coastal waters (Ref. 1998); at temperatures ranging from 7.2-15.6°C. Coastal population are anadromous (Ref, 86798). Migrates up to 1,000 km upstream in rivers (Ref. 6793). Occurs possibly to 425 m (Ref. 2851). Feeds on invertebrates such as amphipods, ostracods, aquatic insect larvae and aquatic worms (Ref. 1998); food also include copepods, euphausiids, mysids and small fishes (silversides, mummichogs and herring) (Ref. 5951, 10294). Headed, gutted, sold fresh, frozen and precooked. Eaten sautéed and fried (Ref. 9988).

Life cycle and mating behavior Maturities | Sự tái sinh sản | Spawnings | Egg(s) | Fecundities | Ấu trùng

Spawning runs occur when temperature is between 8.9-18.3°C, may last for 3 weeks, peak for 1 week. Lengths of both sexes decrease as spawning progress. Two or more tuberculated males maintain position against a female in swift water, eggs released in clusters and presumably milt released simultaneously. Spawning usually takes place at night, spawners move downstream to the lake during daytime.
