宮城県鳴瀬川水系における国内外来ヤリタナゴTanakia lanceolataの確認と遺伝的特徴

抄録

Non-native populations of Tanakia lanceolata were found in the Naruse River system, Miyagi Prefecture (Northern Honshu), Japan. Examination of nucleotide sequences of the mitochondrial DNA cytochrome b region indicated that the population was a genetic lineage of those naturally distributed in Western Honshu, Japan. In particular, a haplotype present in the Naruse River populations was consistent with one identified in populations in the Asahi and Kurashiki River systems, Okayama Prefecture.
