This study aims to enhance the knowledge on endurance swimming capacity and speed of Asian redtail catfish (Hemibagrus nemurus)(Body Length (BL)) 16.13 1.14 cm Average SD) observed in swimming channel of flume tank for development of fishing and aquaculture methods. Swimming speed was negatively correlated to the endurance time. The endurance time decreased when the swimming speed increased. Sustained swimming speed was less than 2.5 BL/s corresponded to 40.3 cm/s and burst swimming speed was recorded up to 10.5 BL/s corresponded to 169.4 cm/s whilst the prolonged speed was recorded at 2.5-10.5 BL/s (40.3-169.4 cm/s). The tail beat frequency of Asian redtail catfish was positive correlation on the swimming speed. The tail beat frequency increased when swimming speed increased. At sustained swimming speed the tail beat frequency was low at 2-4.5 HZ and dramatically increased to reach 10 HZ at prolonged swimming speed.

Abstract

This study aims to enhance the knowledge on endurance swimming capacity and speed of Asian redtail catfish (Hemibagrus nemurus)(Body Length (BL)) 16.13 1.14 cm Average SD) observed in swimming channel of flume tank for development of fishing and aquaculture methods. Swimming speed was negatively correlated to the endurance time. The endurance time decreased when the swimming speed increased. Sustained swimming speed was less than 2.5 BL/s corresponded to 40.3 cm/s and burst swimming speed was recorded up to 10.5 BL/s corresponded to 169.4 cm/s whilst the prolonged speed was recorded at 2.5-10.5 BL/s (40.3-169.4 cm/s). The tail beat frequency of Asian redtail catfish was positive correlation on the swimming speed. The tail beat frequency increased when swimming speed increased. At sustained swimming speed the tail beat frequency was low at 2-4.5 HZ and dramatically increased to reach 10 HZ at prolonged swimming speed.
