Salmo dentex is a trout, a species of fish in the Salmonidae family. It is originated in Bosnia and Herzegovina and also found in Albania, Croatia, Macedonia and Montenegro.

Zubatak (Salmo dentex)

Zubatak (Salmo dentex), trout species is poorly studied due to lack of samples for detailed analyses, hybridisation and diverse and multiple designation of the same trout in different areas. Hutovo blato wetlands are situated in North West of the Neretva river estuary in southern part of Bosnia and Herzegovina. Mediterranean wetland would normally be considered highly productive, shallow warm water area with a high degree of biodiversity. This definition doesn't match Hutovo blato wetlands which have several shallow lakes and channels filled with clear and cold water (around 13° C whole year) creating unique living conditions suitable also for salmonids. And indeed, Salmo dentex is known to inhabit this area. In 2001 was performed a comprehensive ichthyological survey on Hutovo blato: All caught dentex trout specimens were above 20 cm in length, which suggest that they migrate to Hutovo blato in their advanced life stage. According to survey and talks with sport fishermen in the area, the spawning grounds of dentex trout are in deep and fast water flow in the rocky canyon of the Neretva River close to Mostar. These grounds are 40 km from Hutovo blato wetlands, and based on these findings it could be predicted that S. dentex lives in Neretva river during juvenile period, and then started to enter nursery grounds, such as Hutovo blato wetlands.

Zubatak (Salmo dentex) is endemic and extremely endangered, mostly due to destruction of the habitat and hybridisation with introduced trouts and illegal fishing as well as poor management of water and fisheries (dams, overfishing, mismanagement).
