PIKE FISHING
Common Pike: The common pike is found in the lower sections of the Selenge River and its tributaries, as well as in Ugii Lake and Terkh Lake. The species has been intentionally introduced to the Duruu Lake in Western Mongolia.
Amur Pike: The Amur pike is distributed across the Kherlen, Onon, Orshuun, Khalkh rivers, and Buir Lake.
LAKE UGII
A 25-square-kilometer lake located in the Ogiinuur soum of Arkhangai aimag. 7 kilometers long and 5 kilometers wide. At its deepest point, it is about 15 meters. It is 1,337 meters above sea level and is part of the Arctic Ocean basin. Ogiin Lake is fed by the Old Orkhon River from the west, and the Khooloin River flows into the Orkhon River from the northwest. It is covered with ice from November to May. Researchers have determined that there are 14 species of fish, 27 species of floating plants, and 48 species of floating animals in the Orkhon River basin, including red bream, pike, bream, perch, rudd, bream, silver bream, and pike. This feature is a lake where about 150 species of waterfowl gather. Because of its rare birds such as the common goose and spoonbill, it has been registered in the International Network for the Conservation of Geese and Ducks of Northeast Asia. To protect the wetland ecosystem of Lake Ugii, it was registered under the Ramsar Convention at an international meeting held in 1971.
ONON RIVER
The Onon River is the first major tributary of the Black River, originating in the Khentii Mountains of Mongolia. Its catchment area is 94,010 km². It flows northeastward for 298 km through Mongolia, crosses the border of the Russian Federation, and flows through the Inner Baikal region of Siberia. It flows for 445 km through Mongolia, and for a total of 818 km, it merges with the Ingoda River to form the Shilka River. The Onon River freezes from the end of October until it freezes in the second half of November, and is covered with ice for 150-170 days. The average thickness of the ice reaches 1.2-1.5 m. Since it is a fast-flowing mountain river, the autumn freeze lasts for relatively long days (14-25). As April warms up, the river ice thaws and the snow melts, causing spring floods, so the river is not so clear for long. The Onon-Shilka-Khar River is one of the top 10 longest rivers in the world (818 km + 560 km + 2874 km). The Onon River is a mountain river, so it has a high gradient and a fast flow. In some places, the flow speed reaches 1.5-2.0 m/s, but below the Balj confluence it decreases to about 1.0 m/s. The major tributaries of the Onon River, the Agats, Balj, Eg, Barkh, and Jargalant rivers, flow through mountainous terrain with steep slopes.
BALJ RIVER
The Balj River is the largest tributary of the Onon River. It originates from the Khumul Saridag Mountain, located between Burkhan Khaldun and Sokhond, a continuation of the Khentii Range in Russia, and flows for more than 40 km in Russia and about 180 km in Mongolia, before joining the Onon River at Ishin Mountain and Khadyn Uvur in Dadal Sum. The river valley widens towards the end, and its flow branches off into several dense islands. Major rivers such as Khyurkhan, Khumul, Amgalant, Galttai, and Tengeleg flow into the Balj River.
