Taimen Fishing: Mongolia or China?

If your goal is to fish for taimen, the honest answer is Mongolia. China’s Sichuan taimen is critically endangered and is never fished: it is a protected species, never a target. They are also two different species, and the mix-up distorts the whole comparison.

Mongolia or China for taimen? The short answer

For taimen fishing, it is Mongolia. Mongolian taimen (Hucho taimen) supports a legal fishery there, on strict catch and release, with permits and quotas. In China, the Sichuan taimen (Hucho bleekeri) is critically endangered: it is simply not fished.

China can be a superb fishing destination, but not for this fish. Conflating the two leads to asking the wrong question.

Two taimen, two species

Hucho taimen and Hucho bleekeri share a genus but are not the same fish. Hucho taimen, the largest salmonid in the world, is widespread across Mongolia and Siberia. Hucho bleekeri is endemic to China, confined to a few altitude rivers, and far more threatened.

This is not a taxonomic footnote: it separates a species you fish from a species you protect.

Why taimen is fished in Mongolia

Mongolia has built a regulated taimen fishery, fully catch and release, often cited as a model of sportfishing conservation. The strong season is autumn, on streamers and surface mouse patterns, on large taiga rivers.

Access runs through permits, quotas and specialist lodges. It is an expedition trip, but one where targeting taimen is entirely legitimate.

Why taimen is not fished in China

The Sichuan taimen is listed Critically Endangered by the IUCN and has been a first-class protected species in China since 2021, the only salmonid at that level. An estimated 2,000 to 2,500 mature individuals remain, after a steep decline driven by dams, habitat loss and illegal fishing.

Targeting it would be indefensible, and in many cases illegal. On every trip it is never a target, and any accidental catch is released immediately.

So why fish in China at all?

Not for taimen, but for what surrounds it. The Tibetan plateau of Sichuan offers Schizothorax (snow trout) and white-spotted char in nearly untouched altitude torrents, with no Tibet-style entry permit.

It is a completely different trip from Mongolia: less known, closer to a genuine fishing frontier. If that is what you are after, it is the subject of fly fishing Sichuan.
