Grayling is recognizable by its large flag-like dorsal fin. It measures between 25 and 60 cm in length and has no teeth. The skillful swimming, displayed by the acrobatic jumps out of the water when trying to get away from the anglers, makes it one of the most popular catches in Central Europe. Besides Soča, it also inhabits other Slovenian rivers like Sava, Unica, and Savinja.
