Identification of Anguilla japonica and A. mavmovata elvers by allozyme electrophoresis

In Taiwanese waters, the morphologically similar elvers of Anguilla japonica and A. marmorata can be distinguished easily at the following loci examined: CK-D *, LDH-B *, sMDH-A * and sMDH-B *. Among these, CK-D * and LDH-B * have fixed allelic differences which can be used as a synoptic key for easy discrimination of the elvers of these two species.
