Description
The eulachon or candlefish is a small smelt of the family Osmeridae from the north-eastern Pacific. The species grows to about 34 cm and has a slender, silvery body. It is an anadromous fish: as an adult it lives in the sea and coastal inlets and in spring runs up rivers in masses to spawn, after which most die. It is so rich in oil that a dried specimen with a wick can burn like a candle, hence the name candlefish. As a plankton feeder it feeds on zooplankton. The eulachon is of great cultural and food importance to indigenous peoples of the Pacific coast. It is harmless to humans.
