100 Dram Sevan Trout

Issued as part of Armenia's long-running wildlife conservation series, this coin commemorates the Sevan trout — known locally as ishkhan — a species endemic to Lake Sevan that was driven to commercial extinction by the mid-20th century through a combination of deliberate water diversion projects and the Soviet-era introduction of competing fish species. The lake's surface level dropped nearly 20 meters between the 1930s and 1990s as water was siphoned for irrigation and hydroelectric generation.

Captive breeding programs have made partial progress since independence, but wild self-sustaining populations remain critically low.
