To investigate the effects of exhaustive chasing training and detraining on the swimming performance of juvenile darkbarbel catfish ( Peltebagrus vachelli Richardson), we performed exhaustive chasing training daily for 14 days and subsequently detrained fish for 7 days. Chasing training resulted in significant increases in critical swimming speed ( Ucrit), post-chasing peak oxygen consumption rate ( VO2 peak), and heart and gill indexes compared with non-trained controls. Both resting oxygen consumption ( VO2 rest) and excess post-chasing VO2 (EPOC) were unaffected by exhaustive chasing training. Fish that underwent chasing training had lower levels of whole-body lipid content and reduced food intake and growth compared with non-trained control fish; however, condition factor was not affected by chasing training. Seven days of detraining reversed the effects of exhaustive chasing training. Overall, these data suggested that short-term exhaustive chasing training improves aerobic swimming capacity in darkbarbel catfish, but the training effects are reversible over a short period of time.
