Fish community composition and habitat use in the Eg-Uur River System
Abstract Mongolian rivers and their fi sh communities have suffered severe impacts from anthropogenic activities. However, the remoteness of some systems has allowed for the conservation of unique fi sh faunas, including robust populations of Hucho taimen. Conservation of H. taimen requires understa...
