Improved aerobic and anaerobic swimming performance after exercise training and detraining in Schizothorax wangchiachii: Implications for fisheries releases

Effects of Aerobic Exercise Training on the Growth, Swimming Performance, Antipredation Ability and Immune Parameters of Juvenile Rock Carp (Procypris rabaudi)

“…However, there are few reports about aerobic training on the anaerobic exercise and metabolic ability of fish. A recent study found that continuous aerobic training can improve the anaerobic exercise ability of Schizothorax wangchiachii (10 cm/s for 6 and 12 h per day for 30 days) [10]. In this study, the results showed that there was no significant difference in U cat between the control group and the training group (6 weeks of training at a velocity of 1-4 bl s −1 ).…”

“…Aerobic exercise training usually occurs in a continuous, uninterrupted manner. The duration ranges from 2 weeks to 1 year, and the energy for aerobic metabolism is mainly provided by red muscles during training [7,10,11]. Studies have found that aerobic exercise training can have significant effects on the growth performance, spontaneous behavior and swimming ability of fish [7,[12][13][14].…”

Continuous flow stimulation had no significant effect on the growth rate but was conducive to the swimming performance, spontaneous behavior, and nonspecific immune parameter of juvenile Percocypris pingi

“…Poor swimming capacity in farmed fish reduce their antipredation ability, which in turn leads to low survival rates when they are transferred to natural waters (Davison, 1997; Miller et al, 2004). Therefore, flow stimulation before release into the wild may be beneficial to the improvement of swimming capacity in farmed fish and may potentially increase the survivability of released fish (Lu et al, 2020; Shi et al, 2012).…”

“…Anaerobic exercise is powered by anaerobic metabolism and is closely associated with fish behaviors such as crossing rapids, hunting and avoiding predators (Baldwin et al, 1995). This type of exercise has a shorter duration and is often evaluated through the constant acceleration speed ( U cat ) and the swimming endurance time at water velocities above U crit (Hou et al, 2022; Lu et al, 2020). Anaerobic exercise‐related anaerobic metabolism depletes adenosine triphosphate, glycogen, and phosphocreatine, and consumes energy during postexercise recovery period which generally expressed an excess postexercise oxygen consumption (Cordero et al, 2019; Kieffer, 2000).…”

Many studies have found that the influences of continuous flow stimulation on swimming performance of fish may be positive, negative or absent, which are associated with the regime of exercise training and fish species (Davison, 1997; Hou et al, 2022; Li, Pang, et al, 2017; Li et al, 2018; Lu et al, 2020).…”
