Mudminnow (Umbra krameri) fish species information

Scientific Name
Umbra krameri

Common Name
Mudminnow

Biology
Inhabits small irrigation canals and slowly flowing and stagnant waters with dense vegetation (Ref. 26183), usually in small ditches, oxbows, backwaters and shallow lakes (Ref. 59043). Territorial in shallow pools and swamps. Feeds on larger crustacean plankton and invertebrate larvae (Ref. 26183). This species is under threat due to habitat destruction, irrigation works and disappearance of shallow ditches as suitable habitats, restrictions of river inundation, pressure from introduced fish species and chemical pollution (Ref. 26183).
