Identification
The world's largest salmonid — a thick-bodied torpedo-built river giant capable of explosive surface predation on rodents and ducks.
- Olive-green head fading to reddish-brown flanks with small dark cross-shaped spots scattered across the body
- Dark red-orange tail and lower fins
- Broad mouth with the upper jaw extending well past the rear edge of the eye
- Small fine scales giving a smooth almost scaleless appearance
- Small adipose fin between back fin and tail
Where it holds
- Rivers
- Lakes
Behaviour
An apex ambush piscivore famous for explosive surface strikes on rodents, ducklings, and birds drinking at the river's edge. Solitary and territorial — large adults defend kilometres of river. Holds in deep pools, log-jam scour holes, and current seams behind boulders, launching long-distance pursuits in clear water. Peak feeding 8-14°C (46-57°F); activity continues into the day on overcast or turbid water but collapses over 18°C (64°F). Dawn and dusk dominate the bite.

How it's caught
Fly Fishing
Streamer
The defining destination method. Strip giant articulated streamers (15-20cm Game Changers, T-Bones, Pole Dancers) and oversized mouse patterns through deep pools, log-jam scour holes, and current seams. Riffle-hitched mice and surface poppers waked across slow tailouts draw explosive aerial strikes. Heavy 9-12wt switch and double-hand rods, 9-18kg fluorocarbon shock tippet, and aggressive long-strip retrieves are standard. Fish chase from a distance in clear water — keep stripping until the fly is at the rod tip.
Line Fishing
Spinning
Cast big jerkbaits (15-20cm), oversized spoons (40-80g), and large inline spinners across pool tailouts, current seams, and structure edges. Aggressive erratic retrieves with hard pause-and-go cadences trigger reaction strikes. Heavy braid (14-23kg) and a hard fluorocarbon shock leader are essential — these fish run through and into log structure. Common locally throughout Mongolia and Russia where it complements fly tackle.
Live Lining
Drift large dead lenok or grayling on a free-running rig through the deepest pool holds. Free-spool the bait so the fish takes without resistance — taimen mouth and turn before swallowing, so feed line on the take. Used by local subsistence anglers and increasingly restricted in sport-fishing zones; check regulations before deploying.
