How to fish it · for Hucho
When
April–June (trout/grayling); autumn (hucho)
Where
The Sana is a big river by Dinaric standards — wide, cold, and clear enough in its upper reaches to sight-fish rising trout along the limestone edges above…
Why this works
Excellent — water temperature is working for you, but time of day is the limiting factor today. Hucho peak season — cold-water predation at its most active.
Likely species
Gammarids
