North America: Utah Lake and its tributaries in Utah, USA. Two subspecies were recognized: Chasmistes liorus liorus from Utah Lake; and Chasmistes liorus mictus may have arisen as a hybrid between Chasmistes liorus liorusand Chasmistes ardens and replaced the original form of Chasmistes liorus.
Length at first maturity / Tamaño / Peso / Age
Maturity: Lm 46.5, range 44 - 49 cm
Max length : 60.0 cm TL macho / no sexado; (Ref. 35393); edad máxima reportada: 40 años (Ref. 35393)
Formerly most common in deep waters of Utah Lake. Used tributaries of lake for spawning (Ref. 5723, 86798). Adults are pelagic and feed on aquatic invertebrates in the mid-water column. Juveniles inhabit emergent vegetation, apparently as refuge from predators (Ref. 35293).
