Morphological differences between four populations of the soft-mouth trout Salmo obtusirostris

We determined the morphological characteristics of Salmo obtusirostris (Heckel, 1851), from the Jadro and Vrljika Rivers (Croatia), the Neretva River (Bosnia and Hercegovina) and the Zeta River (Montenegro). S. obtusirostris is an endemic salmonid of the eastern Adriatic Basin. Historically, its populations were divided into four subspecies. Detailed measurements included 42 morphometric measures and 8 meristic measures. Diagnosis was based on 8 specimens from the Zeta River, 20 from the Jadro River, 20 from the Vrljika River and 20 from the Neretva River. The results of analysis were compared with those from literature as well as with recent results of molecular analysis. Marked differences between the obtained results and literature data were found. The results will be used in the planning of conservation measures for recovery of some populations of S. obtusirostris.
