Varicorhinus barbatulus, Acrossocheilus paradoxus, and Zacco platypus, are fishes that are commonly found in the mid-stream of rivers in the western Taiwan. To understand their swimming behavior and capacity, a circular tank with a high-speed video camera system was used in the study. The result showed that tail beat frequency of those fishes was linearly increasing with the swimming speed. However, the tail beat amplitude of the fishes had only minor changes, ranging from 0.14(BL) to 0.18(BL), 0.16(BL) to 0.18(BL), and 0.14(BL) to 0.18(BL), respectively. Wave transmitted from the nose tip to the tail end along the body axis. The wave caused by the swing of body had a phase lag. For the fishes, the largest amplitude of body axis occurred on the tail end and the smallest amplitude occurred on a quarter of the body length.
For Varicorhinus barbatulus, the maximum sustained swimming speed was increasing with water temperature and the speed reached maximum at 16℃. As water temperature was over 16℃, the maximum sustained swimming speed declined. For Acrossocheilus paradoxus, the critical water temperature occurred at 19℃. For Zacco platypus, the maximum sustained speed was between 22℃ and 25℃ for body size under 15 cm and between 25℃ and 28℃ for body size over 15cm. The ratio of red to white muscle was increasing on the positions between 25% and 28% of the body length for the fishes. On the position of 85% of body length, the Varicorhinus barbatulus had the highest ratio of red to white muscle with averaged at 10.1± 0.2%, Acrossocheilus paradoxus had a ratio at next with averaged at 9.7± 0.1%, and Zacco platypus had the smallest ratio value with averaged at 7.8± 0.2%. These values positively correlated to their sustained swimming speed.
