Limiting factors: construction of Tashat-Kul Weir and fishing in the spawning period. It wasn’t a fishery species in Kyrgyzstan because of small number. Neither bred nor protected. It is offered to reacclimatize this species in water reservoirs in Tchu Valley.
Possible limiting factors: construction of Tashat-Kul Weir, water pollution, invasive enemies and competitors (sleeper, snakehead etc.). Neither bred nor protected in Kyrgyzstan at present time. It is necessary for the species conservation to prohibit amateur fishing, prevent water pollution, as well as to specify the abundance and distribution.
Limiting factors: lateness (long ontogenesis), unordered excessive fishery, deterioration of spawning conditions and probably impact of introduced predatory fish. In 1965 Ton fish-farm was created, for the artificial support of natural propagation of the species; there is elaborated technology of breeding, at present time the species isn’t bred. It is recommended to conserve this species, resume breeding, prohibit fishery for five years, protect sites of spawning and feeding.
Limiting factors: legal fishery and poaching, deterioration of conditions for the natural renewal and introduction of predatory fish species. There is experience of breading of the species in Kyrgyzstan. At present time it is out of any protection. To conserve the species, it is necessary to prohibit amateur fishing and industrial fishery, organize breeding, protect sites of natural propagation as well as to continue study of causes of small abundance.
Limiting factors: poaching, destruction of natural regime of river flows as a result of hydro-building. It is neither bred nor protected in Kyrgyzstan. It is necessary to prohibit the poaching as well any fishery in the spawning period; additional study of distribution for elaboration artificial rehabilitation is also offered.
Limiting factors: construction weirs that completely interrupt migration ways to the territory of Kyrgyzstan. It is not bred in Kyrgyzstan, as well not protected. To conserve the species, it is necessary to prohibit amateur fishing, to protect sites of spawning and feeding, and to specify the abundance.
Limiting factors: unsteadiness of river-grounds, water pollution, destruction of natural regime of river flows as a result of hydrobuilding, amateur fishing. The species is unknown in captivity in Kyrgyzstan; included into Red Book of the Kyrgyz SSR in 1985. To conserve the species it is essential to prohibit amateur fishing, protect sites of spawning and feeding and specify the abundance

Cyprinidae | SisoridaeCyprinidae
Aral Barbel / Barbus brachycephalus
CR: It is extinct in Kyrgyz, locally distributed Aral endemic subspecies of Aral-Caspian species, one of two congeners in fauna of the country. The subspecies is naturally spread in Amudarya River (in the past), Kashkadarya, Zerawshan, Syrdarya and Tchu Rivers; in Kyrgyzstan it is known from Tchu River in the past. This is large fish, up to 90 cm length and 22.5 kg weight, using for food the bottom-living invertebrates and young fish. Spawning period: the last of April-early in June. Age of the reproduction ability: 4 years, fertility: 8 kg female has 180 thousand eggs. It was always rare in the country, sometimes spawners were observed upstream Tokmak town in insignificant number.Limiting factors: construction of Tashat-Kul Weir and fishing in the spawning period. It wasn’t a fishery species in Kyrgyzstan because of small number. Neither bred nor protected. It is offered to reacclimatize this species in water reservoirs in Tchu Valley.
Eastern Ostroluchka / Capoetobrama kuschakewitschi
CR: It is critically endangered in Kyrgyz, narrowly distributed subspecies of Amudar-Syrdarya endemic representative of the monotypic relic genus. The subspecies is spread in Tchu River from downstream Georgievka village; in Amudarya, Surkhandarya, Kashkadarya, Zerawshan and Syrdarya Rivers – different subspecies. This small bottom-feeding fish (up to 18 cm length) populates shallows and backwaters with pebbly and sandy grounds; no value for fishery. Spawning period: the last of April-the last of July, fertility: 20-40 g female has 2.4–8.8 thousand eggs. Stock in the country is extremely small, no records over last years.Possible limiting factors: construction of Tashat-Kul Weir, water pollution, invasive enemies and competitors (sleeper, snakehead etc.). Neither bred nor protected in Kyrgyzstan at present time. It is necessary for the species conservation to prohibit amateur fishing, prevent water pollution, as well as to specify the abundance and distribution.
Issyk-Kul Scaleless Osman / Diptychus dybowskii lansdelli
CR: rare critically endangered subspecies (limnicolous form) of Tien Shan sub-endemic species. The subspecies is endemic for western, northern and southern parts of Issyk-Kul Lake and corresponding inflows. It is large fish, up to 60 cm length and 16 kg weight; young use for food the filamentous algae, stonewort, zooplankton, mature fish prefer zoobenthos (shellfish and crustaceans). Spawning period: April-May. Males achieve sexual maturity at 4–5, with body length 18–22 cm, females – at 5–6 year, females weighing 0.2-2.0 kg have the fertility 4.000–32.700 eggs. In first half of last century amounts of take were 0.7–0.8 tons annually; in 1960-s 0.02 tons, despite of prohibition of fishery for Scaleless Osman in Issyk-Kul Lake in 1966 the stock is declining; last decades the species is very rare.Limiting factors: lateness (long ontogenesis), unordered excessive fishery, deterioration of spawning conditions and probably impact of introduced predatory fish. In 1965 Ton fish-farm was created, for the artificial support of natural propagation of the species; there is elaborated technology of breeding, at present time the species isn’t bred. It is recommended to conserve this species, resume breeding, prohibit fishery for five years, protect sites of spawning and feeding.
Issyk-Kul Marinka / Schizothorax issykkuli
EN: It is rare endemic Issyk-Kul species with declining number, one of four congeners in fauna of the country. The species is valuable for fishery. It populates all offshore waters in Issyk-Kul Lake but prefers northern shores, usual inhabitant of desalinated zones in Tyup, Jergalan and Pokrovsky Bays. It migrates in winter time to deeper places 40–60 m down. It eats both animals and plants (mainly shellfish and stonewort), large individuals also piscivorous. Spawning period: May- the middle of July, 10–20 % individuals spawn by stages. Fertility: 1,200–93,000 eggs, spawn is large, sticky, toxic, laid on stony eminence. Number is insignificant, 50 years ago ratio of this species in general was 3 %, at present single individuals were registered.Limiting factors: legal fishery and poaching, deterioration of conditions for the natural renewal and introduction of predatory fish species. There is experience of breading of the species in Kyrgyzstan. At present time it is out of any protection. To conserve the species, it is necessary to prohibit amateur fishing and industrial fishery, organize breeding, protect sites of natural propagation as well as to continue study of causes of small abundance.
