“…Changes in DO showed no significant effect on U fast, which was consistent with previous studies on European sea bass Dicentrarchus labrax and golden grey mullet Liza aurata (Lefrançois et al 2005, Lefrançois & Domenici 2006. The absence of a DO effect on U fast is easily understood because the faststart movement occurs within seconds and is mainly limited by ATP and PCr in muscle tissues, and thus may be largely independent of DO levels.…”

“…U crit ) than the other 2 swimming performances. A depressed U crit under lower temperatures and DO concentrations has been widely documented (Pang et al 2011, Zhao et al 2012; however, little work has been performed on U fast and U cat (Lefrançois et al 2005, Lefrançois & Domenici 2006, Wang et al 2012. Furthermore, no study has investigated the effects of different environmental changes on the different swimming capacities within a single fish species.…”

Changing environmental conditions may affect the swimming performance of fish by affecting energy sources through changes in temperature and concentration of dissolved oxygen (DO). It has become increasingly important to investigate the effect of temperature and DO on the swimming performance of fish species as hypoxia in aquatic environments worldwide is increasing due to the effects of anthropogenic global warming. To test how different swimming modes respond to thermal and DO changes, 3 measures of swimming performance were tested: critical swimming speed (U crit ), constant acceleration speed (U cat ), and maximum speed during a fast-start (U fast ). The changes in these 3 aspects of swimming performance in juvenile crucian carp Carassius carassius were quantified at 2 different temperatures (10 and 20°C) and 3 different DO concentrations (2.5, 5, and 9 mg l −1 ). U cat was ca. 110 to 156% of U crit , whereas U fast was ca. 394 to 472% of U crit , depending on the experimental conditions. Temperature had a significant effect on all 3 measures of swimming performance, whereas DO had significant effects only on U cat and U crit (U crit but not U cat decreased in the 2.5 mg l −1 DO group). The active metabolic rate (MO 2active ) under the different experimental conditions suggested that the decrease in U crit at a lower temperature and DO level could be partially explained by a decrease in oxygen uptake capacity. These results indicate that all 3 swimming measurements should be used when addressing how temperature affects swimming performance.

“…The U CAT in the present study was approximately 60% higher than U crit measured in similar-sized sea bass at similar temperatures (Claireaux et al, 2006). The observed U CAT (~150cms -1 ) is still appreciably lower than the velocity of 200cms -1 achieved during a single startle response (Lefrançois and Domenici, 2006) or of 205cms -1 in an aquatic 'drag strip' (Claireaux et al, 2007). Performance in the CAT was independent of size across a fairly broad range, mirroring the previously determined size independence of sprint performance (Nelson and Claireaux, 2005;Claireaux et al, 2007).…”

SUMMARYStudies of inter-individual variation in fish swimming performance may provide insight into how selection has influenced diversity in phenotypic traits. We investigated individual variation and short-term repeatability of individual swimming performance by wild European sea bass in a constant acceleration test (CAT). Fish were challenged with four consecutive CATs with 5min rest between trials. We measured maximum anaerobic speed at exhaustion (U CAT ), gait transition speed from steady aerobic to unsteady anaerobic swimming (U gt ), routine metabolic rate (RMR), post-CAT maximum metabolic rate (MMR), aerobic scope and recovery time from the CATs. Fish achieved significantly higher speeds during the first CAT (U CAT 170cms -1 ), and had much more inter-individual variation in performance (coefficient of variation, CV18.43%) than in the subsequent three tests (U CAT 134cms -1 ; CV7.3%), which were very repeatable among individuals. The individual variation in U CAT in the first trial could be accounted for almost exclusively by variation in anaerobic burst-and-coast performance beyond U gt . The U gt itself varied substantially between individuals (CV11.4%), but was significantly repeatable across all four trials. Individual RMR and MMR varied considerably, but the rank order of post-CAT MMR was highly repeatable. Recovery rate from the four CATs was highly variable and correlated positively with the first U CAT (longer recovery for higher speeds) but negatively with RMR and aerobic scope (shorter recovery for higher RMR and aerobic scope). This large variation in individual performance coupled with the strong correlations between some of the studied variables may reflect divergent selection favouring alternative strategies for foraging and avoiding predation.

“…The actual reaction time of blind cave fish is likely to be greater than this assumed reaction time as the startle response measured by Weiss and colleagues (Weiss et al, 2006) is mediated by the Mauthner cells, which are adapted for extremely fast reactions and represent an extreme for the minimum possible reaction time. However, the reaction times of fish for responses not mediated by the Mauthner cells are of the same order (Eaton et al, 1984;Lefrancois and Domenici, 2006) and would lead to an extension of the detection distance of the order of a few millimetres. For example, a reaction time of 40 ms would lead to a detection distance of 6.5 mm.…”

SUMMARYBlind Mexican cave fish (Astyanax fasciatus) lack a functioning visual system, and are known to use self-generated water motion to sense their surroundings; an ability termed hydrodynamic imaging. Nearby objects distort the flow field created by the motion of the fish. These flow distortions are sensed by the mechanosensory lateral line. Here we used image processing to measure detailed kinematics, along with a new behavioural technique, to investigate the effectiveness of hydrodynamic imaging. In a headon approach to a wall, fish reacted to avoid collision with the wall at an average distance of only 4.0±0.2 mm. Contrary to previous expectation, there was no significant correlation between the swimming velocity of the fish and the distance at which they reacted to the wall. Hydrodynamic imaging appeared to be most effective when the fish were gliding with their bodies held straight, with the proportion of approaches to the wall that resulted in collision increasing from 11% to 73% if the fish were beating their tails rather than gliding as they neared the wall. The swimming kinematics of the fish were significantly different when swimming beside a wall compared with when swimming away from any walls. Blind cave fish frequently touched walls when swimming alongside them, indicating that they use both tactile and hydrodynamic information in this situation. We conclude that although hydrodynamic imaging can provide effective collision avoidance, it is a short-range sense that may often be used synergistically with direct touch.
