Why Mongolia

The river wolf's last stronghold

The Onon holds one of the world's largest wild taimen populations, a fishery so scarce that Mongolia issues roughly five hundred permits a year across just four river systems. We fish it the way it deserves: barbless, single hook, and slowly.

Conservation

Every trophy swims away

Taimen take decades to reach trophy size and exist nowhere else at this scale. Our permits fund river wardens and habitat protection in the Onon-Balj National Park. Luxury here is measured by what we leave untouched.
