Several species and subspecies are currently considered as junior synonyms of Schizopygopsis younghusbandi. The taxonomic status of these should be re-examined as they might be distinct species.[1]
Etymology edit
The Etyfish Project states that the patronym was not identified but clearly in honor of Lieut.-Col. Francis Edward Younghusband (1863-1942), who led a 1904 British expedition to Tibet, during which the type specimen was collected.[3]
Habitat and ecology edit
Schizopygopsis younghusbandi inhabits swift rivers with a rocky substrate, and mountain lakes. It is locally common.[1]
Schizopygopsis younghusbandi has been found to be the prey species that contributed most to the diet of Oxygymnocypris stewartii, a large predatory cyprinid. On average, Schizopygopsis younghusbandi made 59% of Oxygymnocypris stewartii stomach content weight, more so among larger individuals than smaller ones.[4]
Fishery edit
Schizopygopsis younghusbandi is heavily used as a food fish and is among the most important commercial species in the area.[1]
