Salmo ezenami is a critically endangered freshwater salmonid fish, endemic to Lake Kezenoi-Am (Lake Eizenam) in Northern Caucasus.
The only natural habitat where this species occurs is in Lake Kezenoi-Am in Chechnya at the border of Dagestan. This lake is situated 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, Lake Mochokh, probably successfully.Freyhof, J. & Kottelat, M. 2008. Salmo ezenami. In: IUCN Red List of Threatened Species. Version 2010.1. Retrieved 5 April 2010.
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.
Salmo ezenami spawns in the lake, close to underwater springs. Adult fish also probably migrate to tributaries. There are separate small-sized (adults 160–260 mm) and large-sized forms (380–1130 mm). Young prey on and ; adults also eat molluscs and fishes, after the introduction of nonnative species.
