I’m PhD student studying behavioral ecology of diadromous fish, bull shark (Carcharhinus leucas) and chum salmon (Oncorhychus keta). A lot of studies showed they have a potential ability that they can migrate between river and sea. However there are few studies examining their behavior in brackish area, where freshwater and seawater are intricately mixed. I am investigating their surrounding environment and their swimming behavior with bio-logging methods.
