his study examines interspecies differentiation by comparing the morphometric and meristic
characteristics of two endangered trout species (Salmo opimus Turan, Kottelat and Engin, 2012
and Salmo plathycephalus Behnke, 1968) and a species with the potential to be endangered
(Salmo okumusi Turan, Kottelat and Engin, 2014). The research was conducted between 2014
and 2016 in the upper tributaries of the Ceyhan, Seyhan, and Euphrates basins in Türkiye. A
total of 25 morphometric and 24 meristic characters were examined, and the measurements
influencing interspecies differentiation were analyzed using the Random Forest model. The
results indicate that S. plathycephalus exhibits significant differentiation in metric
characteristics. In particular, variables such as predorsal length, head length, and body height
are key distinguishing factors for this species. Among the meristic traits, the number of red
spots and black markings on the operculum are critical for species identification. This study
enhances understanding of species’ environmental adaptations and informs conservation
strategies, laying a foundation for sustainable management. Future research should focus on
habitat conservation efforts.
