Licence and rules
Licence and rules. Bosnia and Herzegovina issues fishing licences through cantonal fishing associations, and the Una is divided between the Una-Sana canton and, downstream, the Republika Srpska. A day ticket bought locally covers a defined stretch and is usually organised through a fishing club or a riverside lodge. Grayling are catch-and-release in most of the upper river; check the local rule, because enforcement is active on the popular stretches.
Season
Grayling from 1 May to 31 October; brown trout all season with a winter closure on some sections
Flow
600–3,000 cfs; the tufa barriers create long, deep pools
The Una is a karst river and stays clear for most of the year, but it responds quickly to rain in the surrounding hills: a summer storm can raise it half a metre in three hours and colour it for a day. The tufa barriers mean the pools stay deep even at low water, so the grayling fishing holds up through the summer when smaller Balkan rivers are too low.
