Comparison of zymograms of myogen and 13 enzymes exhibited that the presence or absence of the six loci, among 26 loci examined, encoding sorbitol dehydrogenase, adenylate kinase, malate dehydrogenase, malic enzyme, tetrazolium oxidase, and phosphoglucose isomerase can be the key characters for identifying the five species of the abalones: Haliotis discus hannai, H. discus, H. gigantea, H. sieboldii, H. japonica, and their hybrids sampled from the coasts of Japan. No. difference, however, was seen between H. discus hannai and H. gigantea with these characters. While, a marked difference was found between specimens of H. japonica collected from Aki, Kochi and those from Yuki, Tokushima with regard to presence or absence of at least one locus, suggesting a necessity of further systematic work in the future. On the basis of observations on hybrids of wild origin, possible overlapping of spawning seasons of H. discus and H. discus hannai was noted in the waters of Oga, Akita and Yuki, Tokushima sampled so far.
