“…Our finding that mummichog fast‐starts speed up with acute increases in temperature is consistent with previous work on this species and other fishes (reviewed in Domenici, and Wilson et al ., ). At higher temperatures, white muscle fibres of axial myotomes exhibit shorter contraction times (Johnson & Bennett, ; Wakeling et al ., ) and produce greater power for rotating the body and pushing against the water (Wakeling et al ., ; Wakeling & Johnston, ).…”

“…The temperature dependence of fast‐starts has been investigated in a variety of fishes, and performance generally increases in warmer environments because turning rates are limited by muscle power (Wakeling & Johnston, ) and muscle power increases with temperature (Johnston & Temple, ; Wakeling et al ., ). There are, however, two exceptions to this trend: performance decreases as temperature nears a fish's thermal maximum (Johnson & Bennett, ; Wilson et al ., ) and at low temperatures acclimation can mitigate performance decrements through altered expression of myosin isoforms and myofibrillar ATPase activity (Johnston & Temple, ; Sidell et al ., ). The exact response of performance to acute temperature change is therefore often dependent on a fish's acclimation conditions.…”

Fast‐start predator‐escape performance of mummichogs Fundulus heteroclitus was tested across field‐informed variation in temperature (24, 30 and 36°C) and salinity (2, 12 and 32 ppt). Performance was similar across temperatures and salinities when fish were allowed to acclimate to these conditions. However, when mummichogs experienced acute temperature changes, performance exhibited thermal dependence in two contrasting ways. Fast‐start turning rates and linear speeds varied directly with the temperature at which the manoeuvre was executed, but these aspects of performance varied inversely with acclimation temperature, with cool‐acclimated fish exhibiting faster starts across test temperatures. Temperature effects were consistent across salinities. These results suggest that while mummichogs increase performance with acute temperature increases, long‐term rises in sea temperature may cause these fish to become more susceptible to predation during abrupt cooling events, such as when storm events flood shallow water estuaries with cool rainwater.

“…Specifically, we found that perch increased their swimming activity at higher temperature and under brighter conditions, the latter in a nonlinear way. Through altering physiological processes and prey distributions (Brown et al, 2004;Hinch & Rand, 1998;Magnuson et al, 1979), temperature influences various behaviours, such as swimming intensity (Alabaster & Stott, 1978;Neuman et al, 1996), foraging rates (Kitchell, Stewart, & Weininger, 1977;Neuman et al, 1996), escape ability of prey (Wilson, Lefrancois, Domenici, & Johnston, 2010) and timing of migration and spawning (McKinzie, Jarvis, & Lowe, 2014). It is likely that perch increased the swimming activity at higher temperature to meet the elevated demand for food, considering that higher swimming activity increases prey encounter rates (Turesson & Brönmark, 2004.…”

Fine‐scale underwater telemetry affords an unprecedented opportunity to understand how aquatic animals respond to environmental changes. We investigated the movement patterns of an aquatic top predator, Eurasian perch (Perca fluviatilis), using a three‐dimensional acoustic telemetry system installed in Kleiner Döllnsee (25 ha), a small, shallow, mesotrophic natural lake. Adult piscivorous perch (N = 16) were tagged and tracked in the whole lake at a minimum of 9‐s intervals over the course of one year. Perch increased swimming activity with higher water temperature and light intensity. Air pressure, wind speed and lunar phase also explained perch movements, but the effects were substantially smaller compared to temperature and light. Perch showed a strong diel pattern in activity, with farther swimming distances and larger activity spaces during the daytime, compared to the night‐time. To investigate the influence of prey distribution, we sampled the prey fish in both littoral and pelagic zones in both day and night monthly using gill nets. We found that the prey fish underwent diel horizontal migration, using the littoral zone during the day and the pelagic zone during the night. However, perch showed the opposite patterns, suggesting either that the prey fish avoided predation risk or that the horizontal diel migration of perch was driven by other mechanisms. Our results collectively suggest that the movement ecology of piscivorous perch is mainly governed by a foraging motivation as a function of abiotic variables, especially temperature and light.

“…Temperature, for example, has a strong influence on the metabolic physiology and locomotory performance of ectotherms (Angilletta et al, 2002 ) and neural performance (Montgomery and Macdonald, 1990 ). The effect of temperature on the fast-start response of fish is variable among species (Wilson et al, 2010 ), but is known to affect escape responsiveness (Webb, 1978 ; Preuss and Faber, 2003 ). Response latency tends to decrease at higher temperatures as a result of the effect of temperature on the speed of nerve conduction.…”

The interplay between aerobic metabolism and antipredator performance: vigilance is related to recovery rate after exercise

et al. 2015

When attacked by a predator, fish respond with a sudden fast-start motion away from the threat. Although this anaerobically-powered swimming necessitates a recovery phase which is fueled aerobically, little is known about links between escape performance and aerobic traits such as aerobic scope (AS) or recovery time after exhaustive exercise. Slower recovery ability or a reduced AS could make some individuals less likely to engage in a fast-start response or display reduced performance. Conversely, increased vigilance in some individuals could permit faster responses to an attack but also increase energy demand and prolong recovery after anaerobic exercise. We examined how AS and the ability to recover from anaerobic exercise relates to differences in fast-start escape performance in juvenile golden gray mullet at different acclimation temperatures. Individuals were acclimated to either 18, 22, or 26°C, then measured for standard and maximal metabolic rates and AS using intermittent flow respirometry. Anaerobic capacity and the time taken to recover after exercise were also assessed. Each fish was also filmed during a simulated attack to determine response latency, maximum speed and acceleration, and turning rate displayed during the escape response. Across temperatures, individuals with shorter response latencies during a simulated attack are those with the longest recovery time after exhaustive anaerobic exercise. Because a short response latency implies high preparedness to escape, these results highlight the trade-off between the increased vigilance and metabolic demand, which leads to longer recovery times in fast reactors. These results improve our understanding of the intrinsic physiological traits that generate inter-individual variability in escape ability, and emphasize that a full appreciation of trade-offs associated with predator avoidance and energy balance must include energetic costs associated with vigilance and recovery from anaerobic exercise.
