Abstract
Cellulose-acetate membrane electrophoresis was performed for the muscle protein of two brackish water amphibious fishes, “mutsugoro” Boleophthalmus pectinirostris and “tobinhaze” Periophthalmus cantonensis, together with “warasubo” Odontamblyopus rubicucndus which inhabits in brackish water but is non-amphibious, and two fresh water fishes, Joach Misgurunus anguillicaudatus and carp Cyprinus carpio for comparison.
Results showed that the patterns are species specific through the five fishes, and that the patterns of both amphibious fishes remarkably differ from those of the three other fishes. No in-traspecific differences were recognized in mutsugoro specimens collected from Ariake Bay, Isahaya Bay, Yatsushiro Bay, and also from Moppo, Korea.
No similarith was observed between the protein patterns of mutsugoro and warasubo, both of which belong to the same family.
