How to fish it · for Hucho
When
April–October
Where
Sister stream to the Bistra, separately permitted, and carrying the same karst-spring character: brown trout, grayling, rainbow, pike, with huchen present.
Why this works
Excellent conditions for huchen. Baitfish present across pool heads and slower runs — cover both systematically.
