Males reach maturity at 2–3 years and females in 5–7 years in females. They spawn in the lake in June–July, but there are also populations in the major rivers draining to the lake. The fish feed on detritus and as adults also on aquatic vegetation.B.

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Lake Sevan
Lake Sevan ( hy, Սևանա լիճ, Sevana lich) is the largest body of water in both Armenia and the Caucasus region. It is one of the largest freshwater high-altitude (alpine) lakes in Eurasia. The lake is situated in Gegharkunik Province, at an altitude of above sea level. The total surface area of its basin is about , which makes up of Armenia's territory. The lake itself is , and the volume is . It is fed by 28 rivers and streams. Only 10% of the incoming water is drained by the Hrazdan River, while the remaining 90% evaporates. The lake provides some 90% of the fish and 80% of the crayfish catch of Armenia. Sevan has significant economic, cultural, and recreational value. Its sole major island (now a peninsula) is home to a medieval monastery. Sevan was heavily exploited for irrigation of the Ararat plain and hydroelectric power generation during the Soviet period. Consequently, its water level decreased by around and its volume reduced by more than 40%. Later two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sevan Trout
The Sevan trout (''Salmo ischchan'') is an endemic fish species of Lake Sevan in Armenia, known as ishkhan (իշխան, ) in Armenian. It is a salmonid fish related to the brown trout. The fish is endangered, because various competitors were introduced into the lake during the Soviet period, including common whitefish (''Coregonus lavaretus'') from Lake Ladoga, goldfish (''Carassius auratus'') and narrow-clawed crayfish (''Astacus leptodactylus''); and because of lake level change. On the other hand, the Sevan trout itself has been successfully introduced to Issyk Kul lake in Kyrgyzstan. A resolution by Armenia's Council of Ministers in 1976 stopped the commercial fishing of Sevan trout and organized Sevan National Park. The fish are nowadays also reared in hatcheries. The Sevan trout has fourGabrielyan, B.K. (2001An annotated checklist of freshwater fishes of Armenia ''Naga'' vol. 24, 23–29.

Capoeta
''Capoeta'', also known as scrapers, is a genus of fish in the family Cyprinidae found in Western Asia. The distribution extends from Turkey to the Levant, to Transcaucasia, Iraq, Turkmenistan , in Armenia,particularly in lake Sevan and northern Afghanistan. This genus is most closely related to ''Luciobarbus'' and in itself is divided into three morphologically, biogeographically and genetically distinct groups or clades: the Mesopotamian clade, the Anatolian-Iranian clade and the Aralo-Caspian clade.Ghanavi, H.R., Gonzalez, E.G. & Doadrio, I.

Fish Described In 1865
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...
