(2009) Movements of (time-series horizontal position) and
habitat use by adult Formosan landlocked salmon (Oncorhynchus masou formosanus) were
examined in a Taiwanese stream, (Chichiawan
Stream) using nano-tag telemetry in summer (typhoon
season) 2007. A great flood caused by a typhoon occurred during
the tracking period in this study, but the flood did not change the
positions or habitat use by the adult salmon. Ten tagged fish
predominately used microhabitats near boulders and made frequent short
movements of < 200 m between habitats.
Key words: Oncorhynchus
masou formosanus, Nano-tag telemetry, Movement, Typhoon flood.
