Description

<p>Acheilognathus tabira, which was has 5 recognized subspecies, was reported in the Takasegawa and Iwakigawa river systems in Aomori. Few studies have examined the classification to the subspecies level and their respective origins in this region. We collected several adults from both river systems. Based on the color of the dorsal fin in nuptial males and the ratio of the long axis to the short axis of the egg, it was confirmed that A. t. erythropterus is occurring in the Takasegawa river system within its range northern-limit. Based on the color of the dorsal fin in nuptial males and the ratio of body depth to standard length, it was confirmed that A. t. tabira is occurring in the Iwakigawa river system. The natural range of this subspecies is the Kansai region (west part of main island of Japan). Therefore, A. t. tabira occurring in Iwakigawa river system is suggested to be an introduced population.</p>
