Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 6 - 7; Afterflossenweichstrahlen: 11 - 12; Wirbelzahl: 36 - 38. Distinguished from its congeners by possessing a unique combination of the following characters: 36-38 vertebrae, strongly elevated neural spines of the last 2-3 preanal and first 6-7 postanal vertebrae, length of adipose-fin base 26.8-30.4% SL, pelvic fins reaching the base of the first anal-fin ray and the presence of pale spots on the body (Ref. 55391).
Body shape (shape guide): elongated.
Found in broad and shallow, well-oxygenated riffles with swift water velocities over rocky substrate (Ref. 55391). Feeds on aquatic insects (Ref. 55391). May spawn in upper reaches of rivers, then migrate downstream following spawning season (Ref. 55391).
