Fish

There was only one fish listed in the original (1985) Red Data Book of the Kyrgyz SSR:

• Turkestan Catfish: A native fish to the mountain rivers of Central Asia.  It is found in the Kara Darya and Naryn Rivers and their tributaries - including the Toktogul Reservoir.  It usually grows up to 18cms in length, although specimens up to 25cms have been recorded, and weighs about 100-120g.  (The larger specimens recorded weighed up to 180g).  The female of the species is normally smaller than the male.  It has a flattened body, with four barbells on its head, and pectoral and pelvic fins for crawling along the sandy, gravel, bottom of the stream bed.  A small eye is placed high on the head.  It is coloured green, yellow and brown - sometimes with brown stripes, and is a light brown on the underside.  It spawns in June.     

In 2005 the list was expanded to include the following species:

• The Issyk Kul Marinka: A indigenous species with small scales arranged in irregular rows.  It sports an intense golden-bronze colour.  It inhabits both the lake and the rivers which feed the lake, and is also found in the Chui and Talas rivers of Northern Kyrgyzstan.  Gernerally it prefers the riverbed habitats of the freshwater rivers - but it has also been noted in parts of the lake which exhibit higher levels of salinity.  It is more common on the northern shores of the lake than the southern - where it can be found in the shallows (5-10m ... or possibly as deep as 25m) in the warm weather but retreating to greater depths (for example 40m) during the winter months.  A typical fish may weigh about 2kg - but specimens upto 80cm and weighing 8kg have been found.  Once important for commercial fishing, with about 15-20 tons caught each year before 1964, it is now a rare sight.
• The Pike Asp: An indigenous fish, native to the Naryn River and now found in the Toktogul Reservoir ... and there are some suggestions that it may also occur in the Chui River.  It resembles a pike with bright silver scales along its long "snake-like" body, a big head with a large mouth and protubing lower jaw.  A typical specimen grows to 80cm and weigh 5kg.
• The Naked Osman: There are several subspecies of this fish which are indigenous to Kyrgyzstan.  Found in both rivers and lakes, the river specimens tend to be smaller than their relatives inhabiting lake environments - about half the size.  The are called "naked" Osman because they exhibit scales only on their their sides and near the anal fin.  It is coloured dark brown on top, silver sides with spots of brown and grey-blue and a yellowish-white underbelly.  A mature adult, at 25 years, can measure 50cm in length and weigh 3kg.  It used to be fished commercially on lake Issyk Kul, with yields reaching 70-80 tons in the 1930's falling to just 5 tons in 1966.  One reason for the decline was that the fishing season coincided with the spawning period - and Osman spawn are poisonous.
• The Sharpray: This indigenous fish has a long, smooth spine along a pronounced dorsal fin - and resembles a Dace.  It "sparkles" a silver colour with a grey back, showing green-yellow tints, and silver white sides and belly, and yellow fins.  It is found in the steppe portions of the Chui River where it prefers river ruffles and pebble and sand beds.  This fish can grow to a length of 16cm and a weight of 55g - although a typical adult specimen is likely to be about 10-13cm and 20-30g.
• The Aral Barbel: Found mainly in lakes, this indigenous fish is pink in colour with dark grey fins, fine scales and barbells around the mouth.  It grows up to 1m long and over 20kg.  It used to be found in the Chui River up to Tokmok, but hasn't been observed in Kyrgyzstan since 1970.
• The Bultman Barbel: This fish is found throughout Central Asia, but has become very rare.  It has a yellowish body with darker, (golden) upper parts and brighter underbelly.  Younger specimens also sport dark spots.  There are two pairs of barbells around the mouth, one pair to the fore and another set back to the rear.  During the Spring and Summer it may be encountered in the Chui river up to Tokmok, but in the Autumn and Winter it inhabits water channels and floodplain lakes.  It can grow up to 1m in length and a weight of 16kg.
