''Salmo ezenami'' is a critically endangered freshwater salmonid fish, endemic to Lake Kezenoi-Am (Lake Eizenam) in Northern Caucasus.〔(【引用サイトリンク】title=Salmo ezenami )〕 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, Lake Mochokh, probably successfully.〔Freyhof, J. & Kottelat, M. 2008. (''Salmo ezenami''. ) In: IUCN Red List of Threatened Species. Version 2010.1. Downloaded on 5 April 2010.〕 ''Salmo ezenami'' used to be the only fish species in Lake Kezenoi-Am. However, two other species, the European chub and ''Gobio holurus'' 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 gammarids and chironomids; adults also eat molluscs and fishes, after the introduction of nonnative species.〔 ==References==
