Body elongate, laterally compressed, greatest depth at anterior of dorsal fin origin. Head moderate; eye moderately large; snout elongate, pointed. Mouth large; lower jaw protruding, maxillary extending to middle of eye or beyond, well toothed on vomer, palatine, pterygoid, basibranchial, dentary, maxillary, and tongue. Teeth specially enlarged on tongue and front of vomer. Body color is pale green on back, with purple, blue, and pink iridescent reflections on the side when freshly caught.

Biology     Glossary (e.g. 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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.
