<p>A genetic analysis of wild-caught tetsugyo from Yutori-numa Pond, Miyagi Prefecture, a long-finned fish of uncertain origin designated as a National Natural Monument in Japan, demonstrated that some specimens were hybrids of goldfish (<i>Carassius auratus</i>) and crucian carp (genus<i> Carassius</i>). Phylogenetic analysis of sequences from part of the D-loop region of mitochondrial and nuclear DNA of 87 Yutori-numa tetsugyo indicated that 66 belonged to the goldfish group and 21 to the Japanese crucian carp group, subsequent PCR-RFLP analysis of c-<i>myc</i> gene revealing three different restriction fragment digest profiles, 21 and 60 specimens possessing goldfish or Japanese crucian carp genes, respectively, and the remaining 6, both genes, indicating their hybrid origin.</p>
