Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1 - 3; Mjukstrålar i ryggfenan (totalt): 9-11; Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 5 - 9; Ryggkotor: 33 - 36. Distinguished by the presence of an adipose fin; small weak spines in the dorsal and anal spines; rough ctenoid scales; and pectoral fins reaching well behind the bases of pelvic fins (Ref. 27547). Gill rakers short, stubby mounds with small teeth; lateral line nearly straight (Ref. 27547). Pale yellowish to silvery, often almost transparent; with a row of about 10 dark spots along midline of back, 10 or 11 spots along lateral line, and another row of spots high on sides above lateral line; fins transparent (Ref. 27547).

Biologi     Ordlista (t.ex. epibenthic)

Occurs in lakes, deep flowing pools of creeks, and rivers (Ref. 5723). Usually found over sand (Ref. 5723). Moves into the shallows of lakes at night to feed and moves back to deeper water as dawn approaches (Ref. 1998). Feeds on insect larvae, amphipods and fishes (Ref. 1998). Important forage fish (Ref. 1998).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Spawning adults move inshore to shallow water or into shallow tributaries of lakes (Ref. 10348). Two or more males cluster with a single female near the surface. They press close to the female, often breaking the surface of the water, and eggs and milt are released (Ref. 27547). Some populations spawn exclusively at night (Ref. 10348), but others show no variation from daytime spawning (Ref. 10349). There is often, perhaps usually, heavy postspawning mortality (Ref. 27547).
