Ecology
Habitat
Amur River Benthopelagic Habitat
This taxon is one of a number of benthopelagic species in the Amur River system. Benthopelagic river fish are found near the bottom of the water column, feeding on benthos and zooplankton
The persistence of mercury contamination in Amur River bottom sediments is a major issue, arising from historic cinnabar mining in the basin and poor waste management practises, especially in the communist Soviet era, where industrial development was placed ahead of sound conservation practises.
Other large benthopelagic river fish of the Amur Basin is the 200 cm yellowcheek (Elopichthys bambusa) and the 122 cm Mongolian redfin (Chanodichthys mongolicus)
