Mongolia ranks among the world's premier fishing destinations, drawing anglers from around the globe to its over 4,000 rivers and 30 lakes—pristine, unpolluted waters where fish populations thrive in remarkable health. The species found here are comparable to those in Europe, yet far more abundant and considerably larger.

The Fish

Among the common species you can fish for in Mongolia are the Siberian whitefish, Siberian grayling, lenok trout, omul, and perch.

Trout fishing is arguably Mongolia's finest offering to the angling world, with skilled fishermen expecting to land at least 30 fish per day in prime rivers—often reaching even higher numbers. The lenok trout thrives throughout the country's waterways, and you needn't venture far to find success (Terelj National Park, Orkhon Valley, Arkhangai, Gun Galuut Nature Reserve). Recognizable by its brilliant crimson-red flanks and downturned mouth, this species is abundant. The Amur trout, rarer and more elusive, boasts a robust body gleaming with gold and dark spots, paired with an aggressive temperament. Average trout length ranges from 45 to 55 cm, with exceptional specimens exceeding 65 cm. They strike readily and with vigor.

For sport fishermen seeking the ultimate challenge, taimen—the largest of the salmonids—is the trophy to pursue. A typical taimen measures between 75 cm and 1 meter, weighing around 5 kg. Above one meter, your catch becomes a true trophy, as these fish can reach up to 150 cm. Pursuing taimen is a pursuit that rapidly becomes all-consuming. These are fierce apex predators, powerful and commanding their freshwater domains. A battle with a taimen is exhilarating—arguably the most demanding struggle you'll experience with a freshwater fish. Seasoned anglers may land one or two per day, though taimen remain stubbornly elusive and notoriously difficult to hook.

We insist that all guests practice catch and release fishing. For fly-fishing, please use single, barbless hooks exclusively. The taimen is a protected species, reaching sexual maturity around seven years of age. A taimen exceeding one meter may be over 25 years old. Even in the healthiest river systems, their populations remain sparse, making it essential to respect these magnificent creatures.

Seasonality

Mongolia's fishing season legally opens June 15th and closes November 1st. The June opening coincides with the post-spawning period, when taimen hunt aggressively and fishing is exceptional. From mid-July onward, river water levels frequently rise excessively, making fishing challenging. Autumn, from August 20th through October, represents peak season. Conditions turn dry and sunny, fish become voracious, and they migrate toward deeper waters in preparation for the freeze.
