Fish Productivity

The article presents an overview of published materials for the period 1963-2020, containing information on the number of larvae and juveniles of fish in different types of water bodies of the Ob River basin (Western Siberia). Data on the fish productivity of rivers and lakes of the Ob basin for steppe, forest-steppe, taiga and tundra natural zones are presented. The Ob River is the main waterway of Western Siberia. The area of the Ob River basin is 2929,000 km2, the length of the river is 3680 km. The existing pronounced differences in the nature of the relief, climate, soils, waters, vegetation of the natural zones of the Ob basin determine the features of the hydrological regime and the living conditions of hydrobionts. Accordingly, the floodplain of the Ob river with its numerous backwaters, kuryami, lakes, sorami is the main places of spawning and feeding of fish. In the course of generalization of the published materials, information was obtained on the number and features of the distribution of juvenile fish in different types of water bodies (channel pits, floodplain lakes, old trees, sores) of the Ob River basin. The results of studies on determining the fish productivity of rivers and lakes of the Ob basin of steppe, forest-steppe, taiga and tundra natural zones are analyzed.

The data on the species diversity of representatives of the genus Teilingia Bourrelly are summarized. from the water bodies of Western Siberia, their distribution by zones and subzones. To date, 4 species and intraspecific taxa from the order Desmidiales are known for the region. Representatives of this family are found mosaically throughout the entire territory of Western Siberia. The largest number of taxa (3) was found in the middle taiga, in the tundra – two species. No species were found in the Irtysh floodplain, forest tundra, northern taiga, forest-steppe and steppe zones. In watercourses, including the Ob and Irtysh, as well as in lakes of different types, 3 taxa were identified, respectively. One species was found in swamps and in temporary reservoirs.

Ob River

Vegetation of the right bank of the Ob River in the limits of Novosibirsk area consists of southern taiga, subtaiga and forest-steppe elements. More over, in comparison with neighboring areas on the West Siberian Plain, it contains the significant amount of mountain elements (Kuminova, Vagina, Lapshina, 1963). Natural vegetation of the area belongs to the forest-steppe subzone of the West Siberian province (Il’ina, 1985). Low percentage of forest coverage is caused by anthropogenic deforestation and wide distribution of meadows (Lapshina, 1963). This is the most endangered vegetation in Novosibirsk area. Spatial vegetation structure was studied by using the model of the Ob River basin covered 184 square kilometers. Well-developed system of ravines and small creeks caused a presence of relatively large areas with very low anthropogenic impact which potentially could be the refuges of pristine zonal vegetation. Main vegetation type of this basin is forest which covered about 31% of the area. Forest diversity of model area consists of four syntaxa of association and subassociation ranks belonging to the Brachypodio pinnati–Betuletea pendulae class. Meadow vegetation is presented by five syntaxa from the Molinio-Arrhenatheretea class and mire vegetation — by two syntaxa from the Alneteae glutinosae class. Two subassociations and four variants are described for the first time. The ravine systems could be considered as low-level landscape structures which are the natural refuges with high level of biodiversity and habitats of rare and endangered species. The slope vegetation organized in ecological rows consists of three up to four syntaxa changing from the top to the ravine bottom. The Ob River Basin flora is characterized by insignificant amount of meadow steppe species, well-represented mire flora and a presence of mountain and taiga elements. The most specific floristic features are the presence of ephemeroid species, taiga species and Siberian tertiary nemoral relics (Polozhiy, Krapivkina, 1985). All these features allow us to refer the river basin vegetation to the low-mountain subtaiga type.

The confirmed fishes of Nizhnevartovsk district waters (Russia, Western Siberia, Khanty–Mansi autonomous okrug (district)) comprise 24 species in 19 genera, 10 families, 6 orders and 2 classes found in Middle Ob River basin. There are also 5 species whose presence in Nizhnevartovsk district waters needs confirmation by the described specimens. The most diverse order is the Cypriniformes with 11 confirmed species (45.9%) followed by Salmoniformes with 5 species (20.8%), Perciformes (3 species, 12.5%), Petromyzoniformes (2 species, 8.3%), Acipenseriformes (2 species, 8.3%) and Gadiformes with 1 species (4.2%). Of the 5 introduced species (including three require confirmation), the freshwater bream Abramis brama (Linnaeus, 1758) and the pike–perch Sander lucioperca (Linnaeus, 1758) naturalized and are constantly found.

First Time

The fauna of the rivers of the north of Western Siberia that do not belong to the Ob’ River basin is of particular interest from the point of view of zoogeography and understanding of the processes of formation of the freshwater malacofauna. Starting in the taiga zone, these rivers flow north and cannot serve as a way of interzonal dispersal of species from lower latitudes. However, information about the fresh-water malacofauna of these river basins is poorly presented in the scientific literature, some of the published species findings are doubtful or erroneous. The gastropod mollusks of the family Valvatidae of the Taz river basin (Western Siberia) are considered. The basin is located closer to the Yenisei than to the Ob’ River basin. The study was based on original authors’ material represented by both qualitative and quantitative samples. It has been found that eight species of mollusks of the genus Valvata occurs in the water reservoirs and streams of the Taz basin, an annotated list of species is presented, and a brief zoogeographic characteristic is given. Three species (Valvata helicoidea, V. sorensis and V. korotnevi) are for the first time recorded from the basin, one of them (V. korotnevi) is for the first time recorded from the Western Siberia waterbodies.

The "Sustainable Development Complex Policy in Mongolia 2030" document represents the "Nomadic Culture" as a tourist hub, indicating that nomadic lifestyle is the main attraction in tourism. One of the main issues of concern for tourism in Mongolia is to focus on the herder lifestyle that differs from each other depending on natural zones. Therefore, we aim to study the different types of farming and lifestyle in such regions, as the Gobi, arid steppe, steppe, forest steppe and high mountain zone and determine which types of tourism are more convenient in each region.

Recreation is the most important part of modern life. However, in Russia, there is still underdeveloped an internal and, especially rural (ethnographic) and archaeological tourism. The paper analyzes the possibility of organization of educational recreation for people in the territory of the Bolshechensky district - one of the most touristic regions in the Middle Irtysh. As a result, the author comes to the conclusion that there are several areas which are the most suitable for the specified activity: this is a chain of old Russian villages, the area of compact residence of Tatars - descendants of immigrants from Central Asia, unique places of archaeological heritage sites (the Batakakovo and Inberen meander core, Chigar meander core etc.). For these places, several types of routes are offered (linear radial, radial-ring, etc.). Being of various archaeological and ethnographic themes they make it possible to show the tourists the traditional routine of the rural population, archaeological sites of different types and archaeological excavations. Keywords: western Siberia, northern forest-steppe, left bank of Middle Irtysh, archaeological, rural (ethnographic) tourism, recreation
