Short description Morfología | Morfometría

Espinas dorsales (total): 6; Radios blandos dorsales (total): 9; Espinas anales 1; Radios blandos anales: 18 - 22. Body bluish brown dorsally, silvery ventrally. A broad silvery band with dark blue upper margin running from pectoral fin base to caudal fin base along midbody. Upper surface of head, pectoral and caudal fins blackish (Ref. 27363). Scales in the lateral line series above the lateral band 52-60; predorsal scales 28-35 (Ref. 47314).

Inhabit coastal lagoons and near estuaries, usually in freshwater (Ref. 27363, 59043). Gregarious. Adults feed on zooplankton. Mature adults spawn for the first time at 1-2 years. Eggs are deposited among aquatic vegetation (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). The fisheries has now flourished especially in lakes and reservoirs, in Peru, Argentina, southern Brazil and Chile.
