Fishing hunting vacation in Karelia

Karelia is often called the land of lakes and rivers. The abundance of freshwater bodies, it is much superior to other areas of the Soviet Union and such foreign countries as Finland, Sweden and Canada, also famous for its abundance of lakes. On the territory of Karelia over 60 thousand big and small lakes with a total area of over 42 thousand square km, including the largest lake in Europe — Ladoga and Onega.

Only one third of the Karelian lakes — waste, the other ows have. Closed to include numerous forest ponds, usually with peat marshy shores, called Lambada. Large, medium and small lakes are part of the flow and often form lake-river systems, connected by rivers and canals. The flowage lakes is a positive one for living in them fish, because it reduces the likelihood of a fish kill caused by lack of oxygen in water in the winter.

The depth of the lakes that are important in fish life is quite varied. The greatest depths are typical for large lakes: Ladoga (260 m), Onega (120 m), Segozero (97 m). On small lakes depths usually do not exceed 3-5 m Deep places often alternate with underwater rocky bottom or shoals, called Lud.

Annual fluctuations of levels that are essential for spawning and juvenile fish life, for most of the Karelian lakes are relatively small and do not exceed 0.5—0.6 m. As for many rivers, natural reservoirs, the lakes provide a uniform flow throughout the year, which gives the opportunity to avoid significant changes of the level regime of rivers in different seasons — level fluctuations of the rivers of Karelia does not exceed 1.5—2 m. For comparison, on the Northern Dvina river they reach 14 m, and on the Lena—even 16 m.

The network of rivers in Karelia, too, is highly developed — its total length is 55 thousand km, but the vast majority is owned by small rivers and streams. Only 7 of the Karelian rivers have length more than 200 km and Many rivers flow through lakes, their connecting channels. Saturation of the Karelian lakes of the river are unmatched in other areas of the country.

A characteristic feature of our rivers — their strong rapids — they have many rapids and waterfalls.

The origin and configuration of most of our lakes are connected with the activity of the glacier that covered 10 to 15 thousand years ago the whole territory of Karelia. In tectonic cracks and depressions, treated by a glacier and filled with glacial waters, as global warming for many centuries formed the hydrographic network, which is characteristic for the modern landscape of our Republic. And with the direction of movement of the glacier is connected with the elongation of many lakes from the North-West to South-East.

In General settling ponds on the territory of Karelia and the formation of modern fauna of fish (in the Quaternary) was due to both the fauna of the basin of the Baltic sea (mainly), and by fauna of the basin of the White sea. Interestingly, some fish species in lakes in Karelia (smelt, vendace) combine the characteristics of the Baltic sea and levitanskij subspecies, suggesting the possible settlement at the time of the same waters the fish from both basins of the seas.

The temperature regime of water bodies of Karelia is formed under the influence its climatic conditions. Summer in shallow lakes, the water gets to the bottom, and the temperature of the surface layers is about 25°C. In deep lakes, low water temperature in the bottom layers is kept during the whole year.

The lake in the North Karelia freeze of about half a month earlier than in the South. Rivers open up earlier than the associated lake to the North, usually in early may in the South in the first half of April. Strong floating of ice on our rivers does not happen, as ice breaks up on numerous thresholds.

Forage resources for fish in lakes in Karelia in General small. This is due to their Northern location and low nutrient content in the water, primarily nitrogen-phosphorus compounds. However, biomass of food organisms in the course of the year varies considerably: in the summer months, many benthic invertebrates (mollusks. larvae of caddisflies, mosquitoes, mayflies), crustaceans and fishes intensively wyedelta, winter activity of fish feed is significantly reduced and the number of these organisms increases.

All the lakes and rivers of Karelia in its flow belong to two marine basins – the Baltic and the white sea.
