“…Piscivorous perch in the study lake travelled on average over 6 km per day-a distance much greater than previously reported for this species (Baktoft et al, 2016;Jacobsen et al, 2002;Jacobsen et al, 2015). In Lake Engelsholm in Denmark, for example, perch were reported to swim approximately 1 km/day .…”

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.

“…Presently, empirical evidence for among-individual correlations between behavior and metabolism, if present, is equivocal. Several studies have reported positive correlations between metabolic rate and behavior (e.g., (Careau et al, 2011;Huntingford et al, 2010;Martins, Castanheira, Engrola, Costas, & Conceição, 2011;Metcalfe et al, 1995;Myles-Gonzalez, Fox, Burness, Rooke, & Yavno, 2015), while others have not (e.g., Farwell & McLaughlin, 2009, Timonin et al, 2011, Le Galliard, Paquet, Cisel, & Montes-Poloni, 2013, Mathot, Martin, Kempenaers, & Forstmeier, 2013, Merritt, Matthews, & White, 2013, Gifford, Clay, & Careau, 2014; see also reviews in Biro & Stamps, 2010, and Baktoft et al, 2016, Biro, Fanson, & Santostefano, 2016. Amongst studies that do report on significant correlations, these are weak or differ amongst contexts or groups (Lantová, Zub, Koskela, Šíchová, & Borowski, 2011, Reid, Armstrong, & Metcalfe, 2011, Killen, Marras, Ryan, Domenici, & McKenzie, 2012, Reid, Armstrong, & Metcalfe, 2012, Bouwhuis et al, 2014, Pang, Fu, & Zhang, 2015.…”

Spontaneous activity rates and resting metabolism: Support for the allocation model of energy management at the among‐individual level

et al. 2019

Despite continuing interest in the proximate energetic constraints on individual variation in behavior, there is presently equivocal evidence for correlations between metabolism and behavior at the among‐individual level. Possible reasons for this include imprecise estimates of individual mean behavior and metabolism due to no repeated measures on one or more of the traits, analyses that do not take into account the labile nature of these traits and the uncertainty in individual estimates, and changing environmental conditions not accounted for. In this empirical study, we repeatedly measured activity rates and resting metabolic rates (RMR) of individual male mosquitofish over an extended period, lasting several months under constant laboratory conditions. Repeatability of each trait was significant (RMR: R = .41; activity: R = .72), indicating consistent variation among individuals, making covariance between them possible. Contrary to expectations, bivariate mixed model analysis revealed that more active individuals had lower RMR (r = −.58) after accounting for mass effects and other covariates. This result suggests that high activity rates require individuals to allocate less energy toward maintenance, and thus provides evidence for the “allocation” model of energy management. We suggest that it would be valuable to study whether and how behavior‐RMR correlations change over individual lifetime, a topic that has yet to be addressed.

“…Our results suggest that the HR‐VPS technology should close this critical gap, finally providing accurate measures of spontaneous activity, foraging ability and habitat preferences in the wild. This will allow individual variation in traits such as metabolic rate, stress responsiveness and personality of multiple individuals in a confined area to be directly related to movement patterns (migration, foraging habits and spawning aggregations) in free‐ranging animals (Baktoft et al., ; Laskowski et al., ; Treberg, Killen, MacCormack, Lamarre, & Enders, ). From a conservation perspective, this technology will facilitate the study of how animal movements change in response to natural and anthropogenic change in variables such as temperature, oxygen and food availability.…”

Field testing a novel high residence positioning system for monitoring the fine‐scale movements of aquatic organisms

Acoustic telemetry is an important tool for studying the behaviour of aquatic organisms in the wild.VEMCO high residence (HR) tags and receivers are a recent introduction in the field of acoustic telemetry and can be paired with existing algorithms (e.g. VEMCO positioning system [VPS]) to obtain high‐resolution two‐dimensional positioning data.Here, we present results of the first documented field test of a VPS composed of HR receivers (hereafter, HR‐VPS). We performed a series of stationary and moving trials with HR tags (mean HR transmission period = 1.5 s) to evaluate the precision, accuracy and temporal capabilities of this positioning technology. In addition, we present a sample of data obtained for five European perch Perca fluviatilis implanted with HR tags (mean HR transmission period = 4 s) to illustrate how this technology can estimate the fine‐scale behaviour of aquatic animals.Accuracy and precision estimates (median [5th–95th percentile]) of HR‐VPS positions for all stationary trials were 5.6 m (4.2–10.8 m) and 0.1 m (0.02–0.07 m), respectively, and depended on the location of tags within the receiver array. In moving tests, tracks generated by HR‐VPS closely mimicked those produced by a handheld GPS held over the tag, but these differed in location by an average of ≈9 m.We found that estimates of animal speed and distance travelled for perch declined when positional data for acoustically tagged perch were thinned to mimic longer transmission periods. These data also revealed a trade‐off between capturing real nonlinear animal movements and the inclusion of positioning error.Our results suggested that HR‐VPS can provide more representative estimates of movement metrics and offer an advancement for studying fine‐scale movements of aquatic organisms, but high‐precision survey techniques may be needed to test these systems.
