Biology     Glossary (e.g. epibenthic)

Occurs in fast flowing streams and rivers with rocky bottom (Ref. 41236). Lives mainly in the middle of streams. Omnivorous. Feeds mainly on filamentous green algae, lesser on chironomid larvae, crustaceans and water beetles (Ref. 40961). Migrate upstream during the breeding season where spawning takes place on stones and gravel (Ref. 41864). Spawns from April to October with a peak in August to September. Male matures at 9 cm. Flesh is considered delicious and market demand is great.
