“…Interestingly in this study morph activity peaked on 536 different lunar phases (Fig.6), significant increase in rate of movement for broad-headed 537 individuals was observed on waxing lunar phases in contrast to highest activity on waning 538 events. The synchronicity in movement of eels in relation to lunar events is similar to that 544 observed for marine species (Henderson et al, 2014). This study shows that there may be 545 links between foraging activity and lunar periodicity in freshwater eels.…”

A fixed receiver array was used to examine the movement patterns and space use of the 34 European eel Anguilla anguilla in an oligotrophic Irish lake between July and September. We 35 assessed home range size, temporal change in spatial behaviour and activity patterns of broad 36 headed (n=11) and narrow headed (n=8) morphotypes. Broad-headed individuals displayed a 37 larger home range (mean KUD 95 (km 2 ):0.296 ± 0.04 S.E.) in comparison to narrow-headed 38 individuals (mean KUD 95 (km 2 ):0.143± 0.02 S.E.). Eel activity was strongly dependent on 39 light conditions. Narrow-headed individuals' movement peaks occurred at dawn and dusk in 40 comparison to broad-headed individuals which exhibited a more stable movement pattern 41 throughout night and into dawn, suggesting that narrow-headed eels are more crepuscular in 42 nature whereas broad-headed individuals are more nocturnal. Lunar phase period also 43 influenced eel movement within the lake. These results provide valuable insights into the 44 spatio-temporal distribution of yellow eels in a lake system, demonstrating that individuality 45 in foraging behaviour has direct influence on spatial patterns. 46 47

“…These results differed from other large coral reef fish such as L. miniatus ( [32], Currey LM, Heupel MR, Simpfendorfer CA, Williams AJ: Do environmental variables influence movement patterns of an exploited coral reef fish?, forthcoming) or P. leopardus [33,34] which appear to move deeper with increases in water temperature, suggesting that individuals were remaining in preferred temperature conditions. A change of a few degrees in water temperature can influence the physical condition, swimming speed and performance [38,39], reproductive performance [40] and growth rate [41] of individuals; consequently, it is advantageous for individuals to remain in areas with optimal temperatures. However, C. ignobilis has a wide distribution ranging from the tropics to subtropics [21,22] and high reef fidelity.…”

Movements and space use of giant trevally in coral reef habitats and the importance of environmental drivers

et al. 2015

Background: Effective conservation of large predators requires a broad understanding of their ecology. Caranx ignobilis is a large marine predator well represented in coral reef environments, yet they are poorly studied. Passive acoustic monitoring was used to track the movements of 20 C. ignobilis at offshore reefs in the central Great Barrier Reef from 2012 to 2014. Using a modelling approach, temporal changes in movement patterns of C. ignobilis were explored to determine if individuals exhibited predictable movement patterns. The effects of biological and environmental variables on monthly space use, daily presence and hourly depth use were investigated to define any response to environmental changes.

“…With ocean temperatures predicted to rise (Poloczanska et al 2007;IPCC 2013), it is uncertain how fish distribution and movement patterns will be affected. Research into the effects of warmer water temperature on reef fishes has focussed on fish metabolism, growth, and reproduction (e.g., Munday et al 2008a;Donelson et al 2010), with few reports of environmental influences on dispersal and distribution (but see: Henderson et al 2014). However, the correlation between temperature and fish presence from data indicated here suggests that L. miniatus may need to alter their distribution or depth use to remain in a preferred water temperature, or avoid sub-optimally warm conditions in the longer term.…”

“…Sensitivity to small increases in water temperature (e.g., Nilsson et al 2009;Gardiner et al 2010) and limited thermal ranges can affect spatial ecology and distribution of populations. Largerbodied species such as P. leopardus and Paralichthys dentatus displayed reduced mobility and swimming performance at higher water temperature (Henderson et al 2014;Johansen et al 2014), which could consequently impact the frequency of encountering and capturing prey (Blake 2004). For L. miniatus, movement to cooler nearby habitats (absence from the monitored array) during warmer periods may provide a physiological benefit, since this species is thought to prefer temperatures below 28°C (Williams et al 2007;Munday et al 2008b).…”

“…In addition to these experimental studies, movement of fishes has been related to large changes in the natural environment. Extreme storm events can alter the distribution of fish populations and severely impact their associated fisheries (Tobin et al 2010;Udyawer et al 2013;Henderson et al 2014). Tropical Cyclone Justin, which impacted the Great Barrier Reef in 1997 caused advection of cold water up onto the continental shelf into shallow reef areas resulting in increased catches of Lethrinus miniatus and decreased catches of Plectropomus leopardus (Tobin et al 2010).…”

Assessing environmental correlates of fish movement on a coral reef

Variation in dispersal and movement patterns of coral reef fishes is likely linked to changes in environmental conditions. Monitoring in situ environmental parameters on coral reefs in conjunction with the movements of fishes can help explain the relationship between exploited populations and their environment. Sixty adult Lethrinus miniatus were acoustically tagged and monitored along a coral reef slope for up to 1 yr. Individuals occurred more often on the reef slope during days of cooler temperatures, suggesting a thermal tolerance threshold may exist. Results indicate that individuals responded to elevated temperatures by moving away from the reef slope to deeper adjacent habitats, thus shifting their position in the water column to remain at a preferred temperature. Space use within the water column (vertical activity space) was not influenced by environmental parameters or fish size, but this result was possibly influenced by use of deeper habitat outside the acoustic array that was not monitored. With elevation of ocean temperature, L. miniatus may need to adapt to warmer waters or disperse into cooler habitats, by either shifting their distribution deeper or towards higher latitudes. Identifying key environmental drivers that affect the distribution of reef fishes is important, and may allow managers to predict the effect of these changes on exploited species.
