Iranian Samples of Brown Trout Salmo trutta or Rainbow Trout Oncorhynchus mykiss: Comparison of Evidence from Allozyme and Mitochondrial DNA Control Region Sequence Analysis

摘要

According to analysis of mitochondrial DNA (mtDNA), in brown trout Salmo trutta five principal phylogeographic groups are discerned (Bernatchez et al., 1992; Bernatchez and Osinov, 1995; Osinov and Bernatchez, 1996; Bernatchez, 2001). The area of theAtlantic group comprises an enormous area from the Atlas Mountains in northern Africa and farther to the north along the Atlantic coast of Europe to the White Sea basin inclusive. The basins of the Black, Caspian, and Aral seas are inhabited by populations of the Danubian group (Bernatchez and Osinov, 1995; Osinov and Bernatchez, 1996). According to analysis of nucleotide sequences of nuclear genes, the populations of brown trout of these three marine basins are the most ancient phylogenetically (Antunes et al, 2002; Presa et al.,2002).
