“…Studies on catfish species found that PMR was inflexible when darkbarbel catfish and southern catfish underwent training ( Li et al, 2010a , b , 2016 ). Though the precise reasons behind these different results are unknown, the change in PMR in cyprinids after exercise training may be partially due to the great flexibility of cardio-respiratory systems, which is the byproduct of natural selection on hypoxia tolerance in cyprinids during evolution ( Nilsson and Renshaw, 2004 ; Fu et al, 2011 , 2013 ). This is again supported by the observations that M. piceus of the 1 and 2 BL s −1 training groups had a higher postprandial PMR compared with the control fish in the present study, which suggests that sustained exercise training had a positive effect on maximum digestive metabolism in juvenile M. piceus .…”

The objectives of this study were to examine whether sustained exercise training at four water velocities, i.e. nearly still water (control), 1 body length (BL) s−1, 2 BL s−1 and 4 BL s−1, has effects on swimming performance and digestive metabolism in juvenile black carp (Mylopharyngodon piceus). The results demonstrated that fish subjected to sustained training at 2 and 4 BL s−1 showed significantly higher critical swimming speed (Ucrit) and maximum metabolic rate (MMR) over the control group. Fish subjected to sustained training at 1 and 2 BL s−1 showed a significantly (30 and 54%) prolonged duration, 14 and 17% higher postprandial ṀO2 increment (i.e. ṀO2peak), and 62 and 92% more energy expended on specific dynamic action (SDA), respectively, after consuming a similar meal over fish kept in nearly still water. These results suggest that (1) sustained exercise training at a higher speed (2 or 4 BL s−1) had a positive influence on the aerobic swimming performance of juvenile M. piceus, which may be associated with improved aerobic metabolism; and (2) sustained exercise training at a lower speed (1 or 2 BL s−1) resulted in elevated postprandial metabolic responses in juvenile M. piceus.

“…If fish were experiencing pain, and if pain was serving a protective function, then fish should respond to fin injury either by not using that fin or by altering swimming behaviour until the injury was repaired. However, after either partial or complete tail fin amputation, fish show no evidence of protecting their fins by reducing their swimming behaviour; they are instead quite capable of swimming continuously against a current (Fu et al 2013). These observations are also consistent with the normal behaviour of fish with bacterial tail or fin rot.…”

Fish do not feel pain and its implications for understanding phenomenal consciousness

Phenomenal consciousness or the subjective experience of feeling sensory stimuli is fundamental to human existence. Because of the ubiquity of their subjective experiences, humans seem to readily accept the anthropomorphic extension of these mental states to other animals. Humans will typically extrapolate feelings of pain to animals if they respond physiologically and behaviourally to noxious stimuli. The alternative view that fish instead respond to noxious stimuli reflexly and with a limited behavioural repertoire is defended within the context of our current understanding of the neuroanatomy and neurophysiology of mental states. Consequently, a set of fundamental properties of neural tissue necessary for feeling pain or experiencing affective states in vertebrates is proposed. While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.

“…A single drop of amoxicillin in 0.5 ppm of concentration was applied at the amputation site before the fish was returned to the holding tanks for ~48 h to recover before any experimental measurement. The whole amputation process was based on the previous protocol [ 11 ]. The experiment was performed in triplicates with a total n number of ~21 fish for each group.…”

“…Tucked pectoral fins along the sides of the body and axial movement alone can generate propulsive thrust [ 10 ]. In addition, the caudal fin is often observed to sustain damage because of predation, disease, or social rank [ 11 ]. In adult zebrafish, as in many other species, axial body bending, together with the fins, is used at all speeds to maneuver and stabilize [ 10 ].…”

The fin is known to play an important role in swimming for many adult fish, including zebrafish. Zebrafish fins consist of paired pectoral and pelvic with unpaired dorsal, anal, and caudal tail fins with specific functions in fish locomotion. However, there was no study comparing the behavior effects caused by the absence of each fin. We amputated each fin of zebrafish and evaluated their behavior performance in the 3D locomotion test using fractal dimension and entropy analyses. Afterward, the behavior recovery after the tail fin amputation was also evaluated, together with the fin regeneration process to study their relationship. Finally, we conducted a further study to confirm whether the observed behavior alterations were from pain elicited by fin amputation procedure or not by using lidocaine, a pain-relieving drug. Amputation in the caudal fin resulted in the most pronounced behavior alterations, especially in their movement complexity. Furthermore, we also found that their behavior was fully recovered before the caudal fin was fully regenerated, indicating that these behavioral changes were not majorly due to a mechanical change in tail length; instead, they may come from pain elicited from the fin amputation, since treatment with lidocaine could ameliorate the behavioral effects after the amputation procedure. However, lidocaine did not accelerate the behavior recovery process; instead, it caused the fishes to display some slight side effects. This study highlights the potential moderate severity of fin amputation in zebrafish and the importance of analgesia usage. However, side effects may occur and need to be considered since fin amputation is routinely conducted for various research, especially genomic screening.
