Mongolia is one of the world's great remaining freshwater fisheries. Asia's continental watershed runs through Mongolia, splitting the country's more than 4000 rivers. Our crystal clear rivers host a number of sportfish including the Taimen, the world biggest salmonid. Taimen often reach 30 kilos. Other target species include the Lenok, Grayling, Pike, Sturgeon and Asian water fish.
The most wide spread local fish species is the Lenok (or Siberian trough). According to locality, it can reach up to 80 cm of length and 4 to 5 kilos of weight. A wonderfully colored, pugnacious fish, it can be handled with all types of bait, streamers offering the most attractive option. Local specimens of the Grayling, normally reach 40 cm of length and being remarkably plentiful, represent a highly distinctive feature of most of Mongolian's rivers. Other species suitable for angling include th Pike, reaching locally up to 130 cm adn averaging around one meter on catching: the Butbot (speciment measuring over one meter have been cought); the perch; the sockeye; the omul and the Amur region, the Amur Pike, the Uskuch Trout, which can reach up to 80 cm; and the Mongol variety of the Silver Salmon.
More than 4000 rivers and more than 30 lakes of Mongolia are distributed into 3 basic water drainage basins.
I. Central Asian Close Drainage Basin
II. Arctic Drainage Basin
III. Pacific Drainage Basin
In the rivers an lakes of the above drainage basins, there are fishers of 76 species of more than 40 families.
