Samsun Bölgesi’nde Yaşayan Salmo Populasyonlarının Genetik ve Morfometrik Yapısının Belirlenmesi: Karadeniz Bölgesi için Yeni Bir Kayıt

Abstract

This study aimed to determine genetic and morphometric characteristics of trout population in Terme Stream, a southern coastal Black Sea drainage. A total of 50 samples were used in morphometric studies and 29 traditional morphometric measurements were taken from all samples with a digital caliper. In addition to morphometric evaluations, mtDNA (cyt b and Control region), and nDNA (Gh2c1) markers were used in molecular studies, too. For molecular studies, DNA was extracted from caudal fin tissue of 10 samples. A total of 991 bp long consensus length of cyt b gene, 974 bp of Control Region and 538 bp of Gh2c1 were obtained (the accession numbers MW871594 for cyt b, MZ055401for Control Region, and MZ055402 for Gh2c1). However, Salmo species from the GenBank database, and also Salmo salar (LC012541-outgroup) were used in phylogenetic analyses. According to the results of this study, a new record, Salmo fahrettini, from Black Sea Region (Terme-Salıpazarı) were described with molecular and morphometric analysis.
