Description

Onychostoma gerlachi is an Asian cyprinid from fast-flowing mountain streams of Southeast Asia. The species reaches about 30 cm and has a streamlined, silvery-grey body and an inferior mouth with a sharp, horny edge on the lower jaw. With this it scrapes algae, periphyton and detritus from stones in the current. Adults live in the rapid flow of clear, oxygen-rich mountain water. The species is regularly eaten and is locally under fishing pressure; the IUCN assesses it as near threatened.
