“…There is growing awareness that such behavioural structure, usually referred to as personality or behavioural type, is frequently present in fish populations as in animal populations in general [19,39,40]. Although there are few investigations of fish personality in the wild, a handful report significant repeatability for a range of activity related behaviours across several species [29,41–44]. Recent advances in technologies such as three-dimensional high-resolution acoustic telemetry now allow measurement of the behaviour of unique individuals at a relatively fine scale over months to years in natural ecosystems [45,46].…”

Encountering a bait is necessary but insufficient to explain individual variability in vulnerability to angling in two freshwater benthivorous fish in the wild

Fish personality traits, such as swimming activity, or personality related emergent behavioural properties, such as the degree of space use shown by an individual fish, should affect encounter rates between individual fish and fishing gear. Increased encounters should in turn drive vulnerability to capture by passively operated gears. However, empirical evidence documenting a relationship between activity-based behaviours and vulnerability to capture by passive fishing gear in the wild is limited. Using whole-lake acoustic telemetry, we first documented significant repeatabilities over several months in a suite of encounter rate-associated behaviours (swimming distance, activity space size, time on baited feeding sites, switching frequency among baited feeding sites, distance to the lake bottom) in two recreationally important benthivorous cyprinid species, the common carp (Cyprinus carpio) and tench (Tinca tinca). We then experimentally targeted both species using stationary angling on baited feeding sites. Individual fish regularly visited the angling sites, documenting that the fishes encountered the angling baits. When attempting to explain individual variation in vulnerability as a function of repeatable behavioural traits, we found no evidence of a significant relationship among various encounter-based behaviours and vulnerability to angling for both species. There was also no evidence for size selection or for energetically less conditioned fish to be more vulnerable. The data cumulatively suggest that fine-scale behaviours after encountering a bait (e.g., frequency of bait intake) may be ultimately decisive for determining vulnerability to angling in benthivorous fish. Based on our work, fishing-induced selection on encounter-based behaviours in recreational angling for benthivorous fish in the wild appears unlikely.

“…Recent applications of biotelemetry have further provided evidence for consistent individual differences in behavior under ecologically relevant conditions and timescales (Taylor and Cooke 2014;Harrison et al 2015), opening the door to the ecological implications of animal personality (Groothuis and Trillmich 2011;Sih et al 2012;Wolf and Weissing 2012). In the wild, however, many animals adjust their behavior in response to environmental changes (i.e., behavioral plasticity), and moreover, the extent of behavioral plasticity may differ between individuals (Nussey et al 2007;Biro et al 2010;Carter et al 2012).…”

“…Furthermore, activity is also important for population dynamics, as it could influence distribution, dispersal, and gene flow (Johnson et al 1992). Activity is a personality trait in many animals (Réale et al 2007;Bell et al 2009), and recent telemetry studies show consistent individual differences in activity in the wild (Taylor and Cooke 2014;Harrison et al 2015). When combined with environmental data, the large amount of movement data provides a unique opportunity to investigate how individual variation in activity responds to changes in natural environments.…”

In contrast to a growing interest in the ecological implications of consistent individual differences in behavior, it is still unclear how consistent those differences are across environmental gradients, especially under ecologically relevant contexts and timescales. We investigated how individual variation in swimming activity of Eurasian perch (Perca fluviatilis) changes in response to natural fluctuations of water temperature as a proxy for an ecological gradient for ectothermic animals. Using an automated acoustic telemetry system, we tracked individual positions of adult perch in a whole natural lake for about 1 year and compared several model frameworks for the individual responses to water temperature. The best-fit model revealed that rising water temperature led to an increase in both between-and within-individual variation in activity, thereby stabilizing behavioral repeatability across temperature. Further, including temporal autocorrelation significantly improved the model performance, suggesting that consistent individual differences in behavior could be partially explained by factors such as slowly changing states in the wild. By using ecologically relevant data, our results revealed complex patterns of behavioral variation in response to an environmental change represented by water temperature.

“…Research on this heterogeneity has tended to focus on internal factors, such as body size and ontogeny, and external environmental cues, such as habitat-suitability, temperature, and light (Lucas and Baras 2001). However, few researchers have explicitly quantified the repeatability and contextual consistency of these spatial behavioral differences, particularly in fishes (see Taylor and Cooke 2014 for an exception).…”

Personality-dependent spatial ecology occurs independently from dispersal in wild burbot (Lota lota)

Although personality has been documented in numerous animals and characters, research into personality-dependent spatial ecology has focused on dispersal. Indeed, few authors have investigated the role of other important spatial traits such as home range, movement distance, vertical activity, and site fidelity, and it is not clear whether these behaviors are correlated with dispersal. In this study, we investigated individual differences in home range, dispersal from release, vertical activity, movement distance, and site fidelity of 44 wild burbot Lota lota over 2 years, using an acoustic telemetry array and a Bayesian mixed modeling framework. We tested whether the spatial behaviors met the following criteria for personality-dependent behavior: repeatability, cross-contextual consistency, and an absence of pseudo-repeatability associated with spatial context choice. We then tested for between-individual correlations among spatial behaviors, indicative of a behavioral syndrome. Our results documented repeatable, cross-contextually consistent, personalitydependent home range, movement, dispersal from release, and site fidelity. In contrast, behavioral differences in vertical activity were inconsistent across sampling years and may have been a product of habitat heterogeneity. Our data indicate a spatial behavioral syndrome occurred independently from dispersal from release, with behavioral types ranging from "resident" individuals with small home ranges, high site fidelity, and minimal movement to "mobile" individuals with large home ranges, high movement rates, and little site fidelity. Our findings suggest animal personality can play a key role in shaping the space use of individuals, and this diversity in spatial behaviors may be too complex to be captured by often used simple linear measures of dispersal.
