Book excerpt: Walleye (Sander vitreus) is one of the most sought after freshwater fish for recreational angling in Canada. Physiological and behavioral measures of stress were used to determine if reduced live-well temperatures and improved water conditions can mitigate stress and facilitate recovery during catch and release angling tournaments. Fish were collected at tournament weigh-in stations to evaluate the effects of live-well water quality parameters and stress mitigation methods on recovery. Fish condition was assessed by measuring plasma cortisol and lactate levels, and observing behavioral cues. This study observed body flex, tail grab, and swim scores and these were determined valuable predictors of stress for Walleye. A commercially available live-well treatment reduced build-up of nitrogenous waste in live wells not replenished with lake water, which is useful while maintaining live-well water quality. High temperature, nitrogenous waste content, and poor weather conditions contributed to higher plasma cortisol and lactate levels, whereas higher temperatures contributed to lower blood glucose levels. Thus it may be best to avoid holding tournaments during the warm summer months or when high winds are forecasted. Additionally, this study shows water quality parameters are an important aspect of the live-well holding periods and tournament organizers should mandate mandatory conditions for live-wells to include continuous aeration and either continuous circulation or the use of live-well treatments depending on season; for instance live-well treatments and temperature control may be preferential over continuous circulation in warm conditions.

Book excerpt: Evaluates physiological response to hooking/playing and hooking/holding (on stringers) stress. Stress imposed under standardized conditions. Blood clotting time was used as index of non-specific physiological stress response. Plasma chloride & hematocrit were used to evaluate osmoregulatory changes & gill ion exchange function. Plasma glucose & plasma cholesterol were used to evaluate changes in carbohydrate & lipid metabolism. Both types of stress produced significant changes in each blood parameter measured, but did not cause any mortality. Physiolo gical responses during recovery phase were very apparent in blood clotting time, hematocrit & plasma glucose.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walleye (Sander vitreus) and sauger (S. canadensis) are closely related freshwater species that are ecologically and economically important throughout North America. These two species are sympatric in many areas, and are often regulated as a single entity. However, the important similarities and differences that exist between these species in the context of various management issues remain uncertain. The first chapter of my thesis addresses the effects of catch-and-release fishing that is part of angling tournaments on walleye and sauger. Catch-and-release tournaments are popular in Saskatchewan and other areas, but frequently prompt management concerns regarding fish health and mortality. Potential sub-lethal effects on movement and habitat use are particularly poorly studied. I tracked both walleye and sauger after catch-and-release using telemetry following four 2015 tournaments. My objectives were to: (1) describe post-release movements; and (2) evaluate factors that may affect postrelease behaviour. The initial movements I observed were highly variable; for example, some fish moved less than 1 km, whereas others moved long distances, the maximum recorded being 31 km. All large movements I observed were made by walleye, while the farthest a sauger moved was 2 km. Fish exited the release area (500 m) faster (2.6±1.1 days versus 3.9±1.6 - 4.4±1.7 days) and moved farther in the first 48 hours (3,712.8±4,427.9 m versus 608.1±392.1 - 1065.3±687.8 m) at one tournament compared to the other three. Stress scores were significantly lower at this tournament (3.50±0.73 versus 4.60±1.17 - 4.75±1.48), and an important negative predictor of fish movement. However, there were few common predictors of movement among tournaments. I confirmed delayed mortality of tagged fish at only one tournament, which was high (45%) and mostly due to avian predation. I conclude that walleye and sauger behaviour after tournaments varies widely, likely due to varying tournament and environmental conditions. The understanding of factors that modify fish behaviour remains limited and warrants further study. The second chapter of my thesis assesses the ecological relationship between walleye and sauger when they co-exist. Limited information is available regarding potential niche partitioning across different time scales by these sympatric congeners, though I expected niche overlap to be high during early ages and lower later in life. I used multi-tissue (liver, muscle, and bone layers) isotopic niche analysis to quantify overlap by these species in two large reservoirs in Saskatchewan. Population niche size was larger for sauger (1.73 - 3.60 ‰2) than walleye (0.51 - 2.61 ‰2) in Lake Diefenbaker, but this trend was reversed in Tobin Lake (sauger = 0.54 - 2.57 ‰2; walleye = 1.30 - 2.94 ‰2). Inter-species niche overlap at the population level also varied by site (Diefenbaker = 3- 19%, Tobin = 9-31%), and niche partitioning was evident in both systems at all time scales. The niche size of individual fish and levels of intra- and inter-specific overlap were highly variable by site. Walleye and sauger appear to use different resources but the factors influencing variation in niche size and overlap are currently unclear. My findings indicate there is considerable variation in the response of walleye and sauger to catch-and-release angling, as well as in their resource use and niche overlap. The important differences I describe between these species suggest that a re-evaluation of regulating them as one entity may be warranted.

Available in PDF, EPUB and Kindle. Book excerpt: Many migratory animals time reproduction using environmental cues (e.g., photoperiod) that signal favorable conditions for offspring (e.g., food availability). However, environmental change can decouple these cues from the conditions relevant to offspring success. In turn, variation in reproductive behaviors may be critical to population persistence in a changing environment. For example, while natal homing can lead to valuable local adaptations in a stable environment, straying to new breeding sites can buffer against environmental change. Among exploited species, knowledge of reproductive behavior, such as spawn timing (phenology) and spawning site selection, has proven useful to fisheries management by influencing angling dynamics, estimates of biological reference points, and stock delineations. Thus, a well-developed understanding of reproductive phenology, breeding site selection, and fishery dynamics could help agencies effectively conserve and manage fisheries in ecosystems experiencing environmental change. Accordingly, my dissertation research sought to better understand the reproductive behaviors and angling dynamics of Lake Erie’s walleye population. In collaboration with other researchers and agency biologists, I used acoustic telemetry, creel surveys, environmental monitoring data, and quantitative techniques to discern the spawning behaviors and angling dynamics of this population. We assessed the timing of residency in spawning sites, focusing on how environmental cues and individual characteristics drive observed variation (Chapter 2), developed a quantitative framework to estimate the frequencies of each potential spawning site selection strategy (Chapter 3), demonstrated sex based-differences in spawning behavior and male-biased walleye harvest during the spawning season (Chapter 4), and modeled the impact of fishery characteristics and angler behaviors on recreational catch outcomes (Chapter 5). Each chapter generated new insights to the benefit of fisheries management through advances in our understanding of reproductive ecology and angling dynamics. In Chapter 2, we found that the timing of residency in spawning sites differed between sexes and among spawning locations and was controlled by photoperiod and temperature. The varying responses to warming suggest that reproductive resilience is promoted by conserving local spawning populations and a broad age structure. The findings from Chapter 3 demonstrated that, although spawning site fidelity and annual spawning are common, apparent skipped spawning also occurs (~ 14% of observations). Accounting for this potential skipped spawning led to revised biological reference points, owing to adjusted estimates of spawning stock biomass. Additionally, although few walleye strayed, the pattern of straying indicated that some stocks mix heavily. In Chapter 4, we found strong evidence for sex-specific spawning behaviors, with males occupying spawning grounds longer than females, which helped explain male-biased walleye harvest on the spawning grounds. Lastly, in Chapter 5, modeling creel survey data showed that angler decisions influenced catch outcomes more than abundance of the targeted walleye population. The findings from this chapter can help anglers maximize their probability of fishing success, given desired catch outcomes. The improved understanding of Lake Erie walleye reproductive behavior, angling dynamics, and the relationships between them, should help agencies worldwide keep their valued fish populations sustainable in the face of continued environmental change.

Book excerpt: Angling practices subject Largemouth Bass Micropterus salmoides to multiple stressors, causing homeostatic physiological disturbances. The combined effects of ambient and live well temperature on stress responses from exercise have not been thoroughly examined. Large numbers of fish required for stress experiments can be produced by intensive culture, but hatchery fish may differ physiologically from wild fish due to dietary carbohydrates. Therefore, the effects of diet, population, and temperature on stress response and health were examined. Stress responses were similar among fish fed formulated and live diets and liver health improved within 4-6 weeks. Although cortisol responses of hatchery and wild fish differed, secondary stress responses were similar. Fish subjected to simulated angling at temperatures of 17, 25, 33 °C with live well temperature differentials of -4, 0, +4 °C, had the lowest resilience to stress at the warmest temperatures, exhausting energy supplies, coincident with metabolic acidosis and poor ion regulation.

Available in PDF, EPUB and Kindle. Book excerpt: Lake and Reservoir Restoration deals with the eutrophication process and the methods to protect, restore, and manage lakes and reservoirs. The most common in-lake techniques or procedures, plus nutrient diversion, are reviewed with regard to their scientific basis, methods of application, known effectiveness, feasibility, drawbacks, and costs. Areas for further research and development are also highlighted. This book is comprised of 16 chapters organized into four sections. After an introduction to the theory of the problem and the restoration technique, the discussion turns to the various restoration methods such as those used for physical and chemical control of nutrients. Diversion and advanced waste treatment, hypolimnetic withdrawal, and dilution and flushing are considered along with phosphorus precipitation and inactivation, sediment oxidation, sediment removal, and hypolimnetic aeration. Case studies and success stories are presented and the costs and potential negative impacts of the methods are examined. The following chapters focus on methods to control plant biomass, including artificial circulation, water-level drawdown, harvesting, biological control, and surface and sediment covers. A chapter on liming acidified lakes concludes this text. This monograph will be useful to professional limnologists and engineers, on-site lake or reservoir managers, and those who are interested in learning about the problems and management of lakes and reservoirs.

Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.
