South America: southern Argentina and Río de La Plata. Introduced into Europe and Asia.

Biology     Glossary (e.g. epibenthic)

Found in shallow coastal waters (Ref. 27363). Reported to inhabit coastal lagoons and near estuaries, usually in freshwater (Ref. 59043). Maximum length estimated from the fact that the congeneric Odontesthes incisa has a common length of 10 cm TL. This species is a cool water predator that has affected the abundance of other species native to the lakes (Ref. 1739). Feeds on zooplankton (Ref. 59043). The fisheries has now flourished especially in lakes and reservoirs, in Peru, Argentina, southern Brazil and Chile.
