Grayling. Part One
What we know about Grayling? I mean not our European and his family from Asia? What exists of their species and subspecies? Where can I catch the largest grayling, and where the least? Try to understand meise this topic ... So, according to certain sources, there are four types of grayling - Siberian, Mongolian, or hubsuhulskyy kosoholskyy and Europe. meise In the past three types subspecies there. But in the Siberian grayling is just 7 subspecies. However, according to other sources, mainly English-speaking, grayling not separated into species and subspecies. They have, for example, arctic grayling meise meet who lives in Alaska, Canada, in the upper Missouri meise River. Famous Russian ichthyologist Mikhail eunuch, in turn, identifies four main subtypes Siberian grayling: West Siberian, East Siberian, Kamchatka and the US (Alaska). Two forms of Siberian grayling, which are clearly different - black and white - living in the lake and its tributaries. He writes that they can be separate species. In addition, one akin form (kosoholskyy grayling) is found in Mongolia - in the lake Hovsgol and associated rivers.
West Siberian subspecies Siberian grayling is found in the basins of the Ob and Yenisei. meise It has a very short dorsal fin with a pattern in the form of spots and bright metallic luster. The body of grayling oblong, greenish or bluish-silver, black in spots on the back, silver, purple sheen on the sides and belly, upper fin large, colorful, bright, chest and abdominal meise red or yellow, purple anal and tail, small head . It reaches a length of 45 cm. And weight 1900 grams. Life expectancy - not more than 10 years. Grayling distributed throughout Teletskoye lake and rivers flowing into the lake. The growth rate depends on the availability of habitat and food base state waters: a seven-year Teletskoye lake specimens reach a length of 40 cm. With a mass of 760 grams in the lower reaches of the Katun - respectively 32 cm and 480 grams. Grayling in the diet is not legible. The basis of food are air insect larvae ephemeral, dragonflies, Caddisfly. Spawning takes place in May - June 8 at a temperature of - 10 degrees in the shallows of the rocky-pebbly soil. Fertility is 1000 - 8000 eggs.
If anyone is interested in additional information on West Siberian grayling, it can be gleaned from a thesis written meise on the subject ( http://www.dissercat.com/content/ekologiya-zapadno-sibirskogo-khariusa-thymallus-arcticus-arcticus-pallas-basseina-reki-lozva ). East Siberian subspecies living in the basin of the Arctic Ocean (from Khatanga and Lena - Ioniveyem to the river, which flows into Kolyuchinsku lip Chukotka). In addition, the East Siberian subspecies penetrated in the Pacific, it can be found in Chukotka - in rivers and Erhuveyemm Ihelhveyem, which flow into the Bering Sea. And it is found in mainland coast of the Okhotsk sea - in all the major rivers of Ulyi to the pits, but two (Tauy and Jan) in the region of Magadan. American (Alaskan, meise Arctic) Siberian grayling subspecies found only in some rivers and lakes Chukotka, near the village Whelan and Lawrence. The main area of his residence is beyond the Bering meise Strait - Alaska and Canada. These basic subspecies Siberian grayling well differ on the picture to dorsal fin, the shape of the head and body, as well as the specifics of biology. In large male East Siberian grayling huge dorsal fin can reach the caudal fin; in the back of the visible rays between 5 - 7 solid dark red stripes. In Alaska grayling meise on a relatively small dorsal fin visible rows of dots-points. In addition, Russian ichthyologists such as Mikhail eunuch and Alexander Antonov emit more grayling number of species that are not found in the references. In Kamchatka grayling meise fin on no solid bands, but there is elongated, merging spots. Kamchatka is different from the East Siberian grayling the relatively large size of the head. There is a difference in body shape: the East Siberian and more vysokotilyy humpback and Kamchatka - podovhuvatyy. Small fish of less than 25 inches harder to distinguish. In some basins (eg, river Gizhiga) live grayling populations with intermediate between Kamchatka and the East Siberian subspecies signs probably hybrid. Earlier the Amur grayling all attributed to the same species - Thymallus grubei. But now it turned out that in the rivers of the southern part of the Far East (south meise of the river and Kieran Uda, including a huge pool Amur and Primorye) lives several distinct species of this genus. Model Amur grayling is easy to distinguish by Bucket jaw and a relatively small dorsal fin with a red border and another parallel bright stripe. Typically, this fish is not large; its weight rarely exceeds 300 grams. In addition, the Amur basin there are other forms of grayling,
