Nerito-pelagic (Ref. 58426). A schooling species that occurs in midwater of lakes or inshore coastal waters (Ref. 1998); at temperatures ranging from 7.2-15.6°C. 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).
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.
