“This is the only place I have been where you put a 20-plus inch trout back as soon as you can as it’s not what you were after! If you dedicated time to the trout and grayling completely you could easily reach a triple digit day.”

Trout

With hundreds of miles of blue-ribbon water and phenomenal numbers of lenok and grayling, many guests have described our trout fishing as possibly the best in the world. Anglers often net more than 30 trout in a single day, all on dry flies. When fishing in a taimen sanctuary, a sunny afternoon drifting hoppers to dozens of 20-inch trout is an incredible bonus.

Lenok (Brachymystax lenok) are found throughout Mongolia. They are a beautiful fish, with silvery bodies, bright red bands, and black spots. These native trout feed aggressively on the surface throughout the summer and autumn. They wait along grassy banks to slurp grasshoppers, or in gravelly runs to sip mayflies and stoneflies or intercept nymphs. Larger lenok will happily destroy a mouse pattern skated across the surface. Their behavior reminds many anglers of cutthroat trout, charging up from the depths to take the fly.

Amur trout (Brachymystax savinovi) are found only in the Amur drainage. They have coppery flanks and big shoulders. They fight hard and will take terrestrials, mice, and streamers.

A typical fly-caught lenok ranges from 14 to 22 inches, while Amur trout average slightly larger. Both species can reach 25 inches or more. Because they are usually quite willing to take the fly, they provide a nice balance to the occasionally obstinate taimen.

Mongolia has several species of grayling, including Arctic grayling (Thymallus articus) and Amur grayling (Thymallus grubii). Trying to catch them all would require a fly-fishing odyssey around Mongolia. If you specifically want to target grayling, the river at Fish Mongolia hosts a more abundant population with a larger average size. 

In short

  • The typical lenok or Amur trout ranges from 14 to 22 inches, with some specimens reaching 25 inches or more

  • Anglers who focus on trout fishing often net more than 30 in a single day.

“I’ve caught at least a dozen big lenok that have attacked the mouse imitations intended for the taimen. I reckon this is a pretty good problem to have.”
