Article
Full-text available
Sustainable global energy production is back-stopped by hydropower which is responsible for a significant share of the green energy produced worldwide. Hydropower, however, does not come without some environmental impacts but has worked to reduce those impacts. Here, we discuss the historical, legislative, and design configurations of hydropower fa...

Full-text available
Background Fish injury and mortality resulting from entrainment and/or impingement during downstream passage over/through hydropower infrastructure has the potential to cause negative effects on fish populations. The primary goal of this systematic review was to address two research questions: (1) What are the consequences of hydroelectric dam fish...
Article
Entrainment at hydropower facilities, where fish (non‐) volitionally enter hydropower infrastructure such as intake towers, can lead to fish becoming stranded for considerable periods of time rather than being flushed to downstream areas. To reduce fish injury and/or mortality from entrainment stranding events, hydropower operators will salvage str...
Article
Full-text available
Potadromous salmonids that reside in hydropower reservoirs often have a high recreational and conservation value. However, the potential seasonal turbine entrainment vulnerability patterns of potadromous salmonids are not well understood. Here, we use acoustic telemetry to test the hypothesis that adults of two species of the Salvelinus genus (bull...
Chapter
The current volume, entitled Climate Change and Non-infectious Fish Disorders (CCNFD) is the first of the two-volume set, and it focuses on the development, physiology and health of fish. CCNFD has 11 chapters organized into two parts. Chapters 1 and 2 (Part I) are mainly for aquatic biologists including colleagues who study non-infectious fish dis...
Article
Full-text available
Repeatable individual differences often account for large proportions of intraspecific variation in animal movements. However, meta-population models have continued to rely on single species-level and season-specific species-level means for movement prediction. Here, we test the hypothesis that repeatable individual differences can account for a si...
Article
Full-text available
Potadromous fishes are vulnerable to involuntary entrainment through hydropower turbines. However, turbines can also provide a downstream passage route for potadromous fish. Here, we review evidence for turbine entrainment and passage in potadromous fish, and evaluate the effects of these processes on upstream and downstream populations. We develop...
Article
Full-text available
Bull trout (Salvelinus confluentus) are a thermally sensitive cold-water species with a threatened conservation status across much of North America. To improve our understanding of bull trout thermal ecology, we tagged more than 150 adults with temperature sensing acoustic biotelemetry transmitters and monitored the animals in a British Columbia re...
Article
Full-text available
1.The variation in migration that comprise partial diel migrations, putatively occur entirely as a consequence of behavioural flexibility. However, seasonal partial migrations are increasingly recognised to be mediated by a combination of reversible plasticity in response to environmental variation and individual variation due to genetic and enviro...
Article
Full-text available
Background This systematic review will address the need for a better understanding of the impacts of fish entrainment and impingement associated with hydroelectric dams on fish productivity in freshwater temperate environments. As the number of dams continues to increase worldwide, so too has concerns for their effects on fish populations. Fish inj...
Article
Full-text available
Despite many similarities and intuitive links between individual dietary specialisation and behavioural inter-individual variation, these phenomena have been studied in isolation, and empirical data confirming relationships between these intraspecific variance sources are lacking. Here we use stable isotope analysis and acoustic telemetry to test t...
Article
In this study, animal-borne telemetry with temperature sensors was coupled with extensive habitat temperature monitoring in a dimictic reservoir, to test the following hypotheses: behavioural thermoregulation occurs throughout the year and temperature selection varies on a diel and seasonal basis, in a winter-specialist diel-migrating fish. Burbot...
Article
Full-text available
In North America, burbot Lota lota (L.), interactions with hydropower are common, southern burbot populations are endangered and hydropower has been implicated in the decline. Thus, the objectives of this review were to identify threats and benefits of hydropower to riverine and reservoir dwelling burbot, assess overall impacts and identify key res...
Article
Full-text available
Animal movement occurs as a function of many factors including changing environmental conditions (e.g., seasonality) and the internal state (e.g., phenotypic traits) of the focal organism. Identifying how these factors interact can reveal behavioral patterns that would otherwise go undiscovered. Given a large sample size of individuals (n = 187), w...
Article
Knowledge continues to emerge on how maternally derived egg hormones influence progeny behaviour in oviparous taxa. Of particular interest is how glucocorticoids (GCs) in eggs, as a signal of maternal stress, affect offspring behavioural traits. To date, research has focused on effects of egg GCs on offspring behaviours within a single experimental...
Article
Full-text available
Biological invasions are a prominent factor contributing to global biodiversity loss. As a result, managing invasive species is a priority for many conservation scientists and natural resource managers. Invasive species management requires a multidisciplinary approach and there is increasing recognition that physiology can be used to inform conserv...
Article
Full-text available
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 beh...
Conference Paper
Fish entrainment through turbine intakes is one of the major issues for operators of hydropower facilities because it causes injury and/or mortality and adversely affects population abundance. Here we used fine-scale acoustic biotelemetry and state-space modeling to investigate behavioural attributes associated with entrainment risk for adult bull...
Conference Paper
Heterogeneity in spatial ecology is often observed within fish populations, although few researchers have investigated whether these between-individual differences are temporally consistent and thus represent personality-dependent behaviour. Furthermore, between-individual differences in dispersal and the relationships between dispersal and site fi...
Article
Full-text available
Background: Fish entrainment through turbine intakes is one of the major issues for operators of hydropower facilities because it causes injury and/or mortality and adversely affects population abundance. Entrainment reduction strategies have been developed based on the behavior of downstream migrating fishes, particularly diadromous species. Howev...
Article
Full-text available
Fish entrainment occurs when individuals are displaced from reservoirs to downstream waters by way of water diversion through turbines or other water release structures. While much effort has been put into quantifying and reducing entrainment of downstream migrating salmonids, considerably less research has focused on fish that are residents in res...
Article
Full-text available
Diel vertical migration (DVM) in pelagic organisms is typically attributed to bioenergetic gain, foraging opportunity, predator avoidance, and multi-factor hypotheses. While a number of benthic species perform nightly migrations into shallower waters, the function of these DVMs have largely been ignored in benthic fishes. We used depth and temperat...
Article
Full-text available
Sexual dimorphism in fishes may be obvious during the reproductive period and less clear during the nonreproductive periods. Despite being difficult to discern during the nonreproductive period, sex-related differences in body condition and shape can yield important insights into a species' behaviour and ecology. The purpose of this study was to te...
Article
In aquatic organisms, diel vertical migration (DVM) is typically characterized as ascent at dusk and decent at dawn. Often several hypotheses are required to explain the sensory-mechanisms and ultimate causes of DVM. Currently, most of the research focused at the individual level has identified DVM functions as a response to light, feeding opportun...
Conference Paper
For fish at temperate latitudes, lake depths offer a range of environmental conditions that can be accessed to optimize physiological processes such as metabolism and maximize species’ and life-stage specific fitness functions. The depths that fish occupy are ecologically relevant, however, only recently have detailed assessments of individual dept...
Conference Paper
Diel vertical migration (DVM) is a strategy common amongst freshwater organisms and is thought to be driven by either thermal habitat selection for bioenergetic advantages, foraging habitat optimisation or predator avoidance. While a larval DVM has been reported for burbot, evidence supporting adult burbot DVMs and nocturnal activity patterns are s...
Conference Paper
To date, the majority of research on fish entrainment in hydropower reservoirs has focused on downstream migrating smolts with comparatively little known about the entrainment vulnerability of adult fish. Given that vulnerability to entrainment is likely to fluctuate with seasonal changes in adult behaviour (e.g., spawning migrations), the first st...
