As a sport activity, fishing is very popular on River Sana as it is abundant in different fish, the most famous and appreciated being the Danube salmon.
The Sana springs are near the village of Vrbljani, Ribnik municipality. Those are three very strong springs forming this river course.
The River Sana flows through Ribnik municipality with its upper part and represents a very significant tourist potential. The river is inhabited by salmonid fish (grayling, trout and Danube salmon), which indicates how unpolluted the river is.
