Abstract
Sinogastromyzon puliensis was observed climbing above the water surface on the wall of the fishway of the Jiji Weir in Taiwan. From observations of the annual and daily movements, we conclude that the species migrates in the middle reach of the Choshui River. Juveniles of S. puliensis migrate 24 hours a day mainly from August to November, with peaks in counts between 15:00 and 20:00 h. © 2008 by Verlag Dr. Friedrich Pfeil, München, Germany.
