In order to contribute to the taxonomy of “ayu” Plecoglossus altivelis which is considered to be closely related to Salmonidae, the hemoglobin (Hb) of this fish was examined by starch-gel electrophoresis. Results showed that “ayu” Hb is composed of 9-14 components, all of which migrate anodically. The electropherogram was found to depend on the ageing of “ayu”: With the growth of this fish, several components of larger mobilities decreased in relative proportions and some of them even disappeared completely, and correspondingly some slowly migrating components were reinforced. No significant dependence on other factors such as the locality and season of catch, sex, etc. was recognized. The above ontogenetic changes of “ayu” Hb seemed to give some support to our previous hypothesis on the evolution of Hb.
