(Heckel, 1852)

Salmo dentex is a variety of

monophyletic unit that could be distinguished from other salmonids as a separate species.[5]

Salmo dentex has been reported to inhabit the

Livanjsko field in Bosnia and Herzegovina[9] and in river Alfeios in Greece.[10]

The status of S. dentex, locally known as the zubatak, long remained unclear due to lack of samples for detailed analyses, hybridisation with other trout lineages and diverse and multiple designations of the same trout in different areas. One of the inhabited areas, the Hutovo Blato wetlands, is situated North West of the Neretva river estuary in southern part of Bosnia and Herzegovina. This is an atypical type of wetland, characterized by several shallow lakes and channels filled with clear and cold water (around 13 °C whole year) creating conditions suitable also for salmonids.[4]

Recently the genetic structure of S. dentex and its relations to other co-existing salmonids in the Neretva and Skadar river systems have been studied using

marble trout (S. marmoratus) formed a genetically unified cluster, while Skadar S. dentex ("strun") was "genetically distinct from S. marmoratus in the same river system and indistinct from local brown trout (S. trutta)". Thus the Neretva and Skadar S. dentex are not closely related but rather "S. dentex [is] a particular life history form of S. marmoratus in the Neretva basin and of S. trutta in the Skadar basin". "These results clearly demonstrate that S. dentex does not represent a monophyletic lineage and should not be considered a distinct species."[5]
