Salmo ezenami is a critically endangered freshwater salmonid fish, endemic to Lake Kezenoi-Am (Lake Eizenam) in Northern Caucasus. The only native occurrence, in Lake Kezenoi-Am in Chechnya at the border of Dagestan, is in a cold alpine lake (area 2.4 km2, maximum depth 74 m, 1870 m altitude). In addition, the species has been introduced to another lake in Dagestan, , probably successfully. Salmo ezenami used to be the only fish species in Lake Kezenoi-Am. However, two other species, the European chub and Caspian gudgeon have been introduced, and present a threat by eating the fry of Salmo.
