Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 13.2 range ? - ? cm
Max length : 50.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 12187); 最大年齡: 4 年 (Ref. 59043)
背棘 (總數) : 6; 背的軟條 (總數) : 9; 臀棘: 1; 臀鰭軟條: 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).
身體藍色的褐色背面, 銀色的腹地。 一條寬的銀色條紋用從胸鰭基底到尾鰭基底延續的深藍色上緣沿著身體中央。 頭部的上表皮, 胸鰭與尾鰭鰭黑色的.(參考文獻 27363) 在側面的條紋 52-60 上面的側線系列中的鱗片; 前背的鱗片 28-35.(參考文獻 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.
也發現於沿岸淺水區。 (參考文獻 27363) 最大的長度估計自同屬的 切齒牙漢魚〔Odontesthes incisa〕 有一個 10 公分 TL 的普遍長度的事實了。 這種是原產於湖的已經影響其他種的豐度的一個冷的水掠食者。 (參考文獻 1739) 在祕魯，阿根廷，巴西南部與智利,漁場現在已經在湖與水庫活躍尤其。
