Koghak is a type of endemic Armenian freshwater trout inhabiting Lake Sevan, a high-altitude freshwater lake in the Gegharkunik Province. Also known as capoeta sevangi or Varicorhinus capoeta, this fish is used in some of the traditional Armenian fish specialties, including roasted koghak, and koghak steamed with vegetables.
This Armenian fish specialty is available at fancy restaurants around Lake Sevan and on the beaches surrounding it, where the freshly-caught fish is being grilled right away. Along with other native species found in this lake, Sevan koghak production has long been significantly decreased and is now under threat of becoming extinct.
