▼ Selenium (Se) is an essential trace element that undergoes maternal transfer to offspring where it has a high degree of teratogenic potential in egg-laying vertebrates because of the narrow range between nutritional benefit and toxicity. Studying this phenomenon of Se maternal transfer and subsequent toxicities in offspring is difficult in many fish species for logistical and biological reasons. For instance, Se contaminated sites are often located in remote locations which can make sampling efforts problematic, and certain fish species of concern commonly have long reproductive cycles and/or complex life histories which can be difficult to monitor. Thus, there is a need for improved methods to assess the toxicity of Se across diverse species of embryo-larval fish which could potentially aid site-specific risk assessment of Se contamination. Microinjection methodology is a potential surrogate for simulating the maternal transfer of Se and could be utilized to study this phenomena in non-model species which are unable to be spawned in the laboratory, or are difficult to sample from an Se contaminated site when spawning. Therefore, the overall objective of my research was to compare two potential in ovo Se exposure routes, maternal transfer and microinjection, in the fathead minnow Pimephales promelas to determine if early life stage toxicities are comparable between these different exposure routes in a freshwater fish. My thesis research fulfilled this objective by characterizing the effects of dietary Se exposure in P. promelas on fecundity and the maternal transfer of Se to embryos, the subsequent toxicities in embryo-larval offspring, and then used this information to inform a microinjection study with P. promelas embryos to allow for a comparison between the two different in ovo exposure routes. First, a 28-day short-term reproductive assay with P. promelas was performed to determine the dynamics of dietary selenomethionine (SeMet) exposure on maternal transfer and its effects on the F1 generation. Sexually mature P. promelas breeding groups (2 females:3 males) were fed a diet of either control (unspiked) or SeMet-spiked food (Low: 3.88 µg Se/g food dry mass [dm]; Medium: 8.75 µg Se/g food dm; High: 29.6 µg Se/g food dm) and allowed to breed. Fecundity did not decrease in female fish exposed to elevated levels of dietary SeMet and the low treatment (3.88 µg Se/g food dm) produced on average the most embryos per female, suggesting a possible supra-nutritional benefit of SeMet on reproduction. Dietary exposure with SeMet-spiked food rapidly induced the maternal transfer of excess Se and embryo concentrations increased daily until reaching steady-state after approximately 14 days of exposure. In ovo exposure to elevated Se did not affect hatchability of embryos or survival until swim-up in early life stage P. promelas. However, a dose-dependent increase in the frequency of larval fish with any type of morphological abnormality (e.g. edema, skeletal, finfold, craniofacial) present at swim-up was observed at embryo Se… Advisors/Committee Members: Hecker, Markus, Janz, David M, Eames, Brian F, Liber, Karsten, Luek, Andreas.

▼ A commonly prescribed contraceptive, the synthetic progestin norethindrone (NET) inhibits ovulation in humans. However, ecotoxicological data are lacking. Preliminary tests produced an LC50 for NET of > 1.0 mg/L (96-hour, fathead minnow (FHM) and medaka) and a NOEC of 242.0 µg/L, a LOEC of 485.0 µg/L (7-day, growth for FHM and medaka). Reproductive testing revealed a LOEC for fecundity of 24.1 ng/L (21 days, medaka). Further testing confirmed the LOEC of 24.1 ng/L while defining a NOEC of 4.7 ng/L (28 days, medaka). Effect of NET in medaka life-cycle exposure at concentrations exceeding 4.7 ng/L was evident. Few females were present in the 24.7 ng/L exposure concentration, with none in the 104.6 ng/L. Egg production was significantly reduced at concentrations exceeding 4.7 ng/L. Additionally, weight, condition factor and somatic indices were significantly different in males exposed to concentrations exceeding 4.7 ng/L. For fecundity and sexual differentiation; the NOEC was 4.7 ng/L, the LOEC 24.6 ng/L; growth and somatic indices, the NOEC was more appropriately 0.9 ng/L, with effect evident at 4.7 ng/L. Sexual differentiation of the F1 population was similar to the F0. A defining result of this test was development of exceptionally large ovaries in NET- exposed female medaka, perhaps indicative of a threshold limit for exposure in these fish. Results of FHM life-cycle testing were similar, establishing a NOEC for fecundity of 0.9 ng/L, a LOEC of 4.8 ng/L. NET's inhibitory effect on gonadal development was obvious; GSI NOEC for males, 4.8 ng/L, and histological examination confirmed the presence of intersex development at elevated concentrations. Normal physical development and growth were impaired, generally at concentrations exceeding 24.1 ng/L. At exposure concentrations exceeding 4.8 ng/L, external sexual confirmation of fish was difficult; LOEC for finspot development in females, 4.8 ng/L. Sexual determination of the 97.1 ng/L exposure group was impossible; externally, all fish appeared male and internal examination revealed no gonadal development.

▼ West Nile virus (WNv) has become a significant and increasing threat to wildlife populations and human health throughout North America. Mosquito control is an important and potentially effective means of controlling the spread of WNv, as the virus is primarily spread between avian and mosquito vectors. This is of particular concern for avian host species such as the Greater sage-grouse (Centrocercus urophasianus), where WNv has been documented to negatively affect sage-grouse survival to the point of possible local extirpation. The most common mosquito control methods focus on controlling mosquitoes at their larval life stages. Efforts have primarily been limited to larvacide pucks or sprays, which require repeated application and could have potentially negative ecological consequences. Here, my primary objective is to test the efficacy of using fathead minnows (Pimephales promelas) as a biological control for mosquito populations in northeastern Wyoming. Specifically, I address two main questions: 1) does the presence of fathead minnows influence mosquito larva density within reservoirs, and 2) what pond and water quality characteristics support viable populations of fathead minnows? In the summers of 2013, 2014, I introduced minnows into 9 of 16 monitored reservoirs. The presence of fathead minnows, mosquito larva density, and adult mosquito populations were monitored at all sites on a weekly basis during 2013. During the 2014 and 2015 seasons, tissue samples were collected for stable isotope analysis, and fathead minnow population density was measured and recorded at the beginning and end of each season. Results indicate that minnows are a promising alternative to controlling mosquito larvae density within these reservoir environments. The presence of fathead minnows lowered and suppressed temporal variation in mosquito population densities throughout the summer seasons. Additionally, self-sustaining minnow populations established at the majority of sites. Water quality parameters measured did not influence survivability at the ranges detected in these reservoir environments. Overall, the efficacy, life history traits and tolerance ranges of the fathead minnow make them ideal biological control option in cattle reservoirs within arid rural environments.

▼ Total copper concentrations of 10 [mu]g/l to 100 [mu]g/l appeared to alter the predator-prey interactions of fathead minnows (Pimephales promelas) and Daphnia pulex. The effect of copper concentration on the total amounts of D. pulex consumed over a 12-h period varied with the density of prey stocked hourly in the aquaria. Four prey levels of 5, 10, 20 and 30 D. pulex per 20 l aquarium were used and control consumption rates ranged from 0.9% to 4.3% of dry minnow body weight. The functional consumption response to prey density shifted from an hyperbolic-Type II toward a sigmoidal-Type III shape and the predators became more efficient at obtaining prey at lower densities as copper concentration increased. Consumption was slightly depressed at intermediate levels of copper and prey density, it was greatly enhanced at high levels of both. Mechanistic components of the functional response, total time spent searching and average time spent in pursuit of a prey item, showed an opposite pattern of response. At intermediate levels of copper concentration and prey density the total time spent searching and average time spent in pursuit increased while capture success and prey consumption fell slightly relative to controls; at high levels of copper and prey the total searching time and average time spent in pursuit decreased while capture success and prey consumption increased. Significant (P < 0.05) increases were observed in predator reactive distance with increased copper dose and prey density held constant. An assay of prey activity levels showed at least a 50% reduction in gross swimming activity of D. pulex at all dose levels of copper. The effects of copper on the mechanistic components could not be used to predict the effect of copper on the functional response but indicated the shift in functional response was due to the differential susceptibility of predator and prey to copper and effects of copper on fish appetite.

▼ Contaminants of emerging concern (CECs), for example estrone (E1), and their effects to aquatic organisms have been researched consistently, however little is known about how temperature can influence exposure effects of CECs. Chemical exposures and temperature have been shown to independently affect fish and their populations, but little is known about their impact on predator-prey relationships. Previous studies indicate that changes arise through behavioral and physiological changes in either predator or prey. To test the effects of E1 and temperature on predator-prey relationships, adult bluegills and larval fathead minnows were exposed to E1 (125, 625 ng/L) or an ethanol control for 30 days at four temperatures (15°C, 18°C, 21°C, 24°C) to reflect natural variation between seasons.Behavioral experiments were conducted to assess the effects of temperature and estrone exposure on minnows in the larval life stage (i.e., foraging and predator evasion). Significant differences due to water temperature were observed in body length, escape angle, and total escape response of predator evasion responses. On day 30 of exposure, predation trials were performed using one adult sunfish and a group of five control and five exposed (125 or 625ng/L) larvae. Exposed larvae (125ng/L: 49.2%; 625ng/L: 52.9%) displayed a concentration-dependent reduction in survival in comparison to the control minnows (74.2%) following predation from the sunfish predator. Additionally, the prey catching abilities of the sunfish may have been affected, potentially mitigating the predation effects on the minnows. In addition, a series of anatomical and physiological endpoints were explored to assess the independent and interactive effects of estrone exposure and temperature on plasma vitellogenin induction, blood glucose, histology, and morphometric indices on sunfish in the adult life stage. This study provides evidence that minnow populations may suffer due to impaired predator evasion performance and provides information for environmental agencies evaluating ecological effects of exogenous estrogens and climate change.

▼ Aquatic species are exposed to a diverse class of contaminants of emerging concerns (CECs) throughout different life stages. In this study, the effects of CECs in increasing complexity on three life stages of fathead minnows (Pimephales promelas) were assessed using existing Great Lakes tributaries’ chemical occurrence and concentration data. Fathead minnows were exposed to either a water solvent control, or the following chemicals: 4-nonylphenol (surfactant), 5-methyl-1H-benzotriazole (corrosion inhibitor, anti-freezing agent), atrazine (herbicide), bisphenol-a (plasticizer), desvenlafaxine (antidepressant), fexofenadine (allergy medication), estrone (hormonal medication), metformin (antidiabetic medication), metolachlor (herbicide), N,N-diethyl-m-toluamide (insect repellent), sulfamethoxazole (antibiotic), tris(2-butoxyethyl) phosphate (flame retardant), fluoranthene (byproduct of organic raw material pyrolysis), imidacloprid (insecticide), triclosan (antibacterial), ibuprofen (anti-inflammatory medication), 17-beta estradiol (hormonal medication), 2,4,6-trinitrotoluene (energetic), 2,4-dinitroanisole (energetic), 2,6-diamino-3,5-dinitropyrazine-1-oxide (energetic), 2,4,6-trinitro-3-bromoanisole (energetic). All chemicals were used in exposures singly and in mixtures of different complexity. Concentration series for the exposures was centered on medium concentration which contained the highest environmentally measured concentrations while low exposure used 1/10^th, ultra-low 1/100^th and the high exposure was set to 10x the medium exposure concentration. Adult and larval exposures were conducted simultaneously, while embryonic exposures were conducted at a later time using the same exposure waters. The apical endpoints for the study were survival, overall health, and several reproductive behaviors for adult fathead minnows. Survival, and feeding efficiency data were collected for larval fathead minnows. Lastly, time-to-hatch, and developmental abnormality for fathead minnow embryos were also recorded. Results suggest that the 96 hours CEC exposures affect different apical endpoints depending on the exposed life stage. As the complexity of the chemical exposure increased, alterations in endpoints such as courtship behavior in adult fathead minnows became more frequent. Medium and high concentrations elicited the greatest effects. In both single chemical and mixture exposures, concentration-dependent responses were not observed. This study highlights the need for complementary studies at different exposure time points as well as in vivo studies to identify potential “biological fingerprints” of single chemical effects in complex mixtures.

▼ Fish skin is a metabolically active tissue that responds quickly to stressors and is the first line of defence against physical damage. Club cells, characteristic components of Ostariophysian fish skin, release their contents into the surrounding water upon rupture (e.g. during predation). These chemical cues act as public information of predation risk. Despite the assumption that club cells evolved under the selective force of predation, studies demonstrated that predation has no effect on club cell investment. Rather, club cell production is stimulated by skin penetrating pathogens and parasites. The experiments in this thesis investigate the responses of fish skin to manipulated pathogen risk. In the first experiment, fathead minnows (Pimephales promelas) were exposed to varying infective risk from two pathogen species that differ in pathogenicity, Saprolegnia ferax and S. parasitica. Although there was no difference in club cell density between fish exposed to the two Saprolegnia species, fish exposed to high concentrations of the pathogens had smaller club cells than those exposed to low concentrations. These results are the first to demonstrate a pathogen effect on the size of club cells. The second experiment investigated whether the physical presence of the pathogen was necessary for an alteration in epidermal parameters or whether Saprolegnia parastitica conditioned water was the only stimulus necessary to evoke a change. Results indicated a lack of treatment effect on club cell density, club cell size or epidermal thickness. The third experiment investigated the timing of club cell changes following a pathogen challenge. Although fish exposed to the Saprolegnia ferax treatment had higher club cell density than fish exposed to the control, there was no difference in club cell density between fish sacrificed on day 3, 6, 9 or 12. A portion of the test population for the third experiment was infected with black spot disease. When analyzed separately, trematode infected fish had smaller club cells than those that were uninfected. In light of inconsistent epidermal responses to pathogen challenges, and comparison with other studies, assessment of environmental stressors and population differences that may affect experimental outcomes and potentially interact with infectious agents is advised.

▼ Adequate levels of dissolved oxygen (DO) are essential to the health of most aquatic organisms. While diel fluctuations in DO concentration are a normal occurrence in aquatic ecosystems, anthropogenically-produced periods of prolonged hypoxia have the potential to cause changes in growth, reproduction and behaviour in animals. My thesis examined reproductive behaviour and physiology of fathead minnows (Pimephales promelas) following exposure to several concentrations of dissolved oxygen. Using a custom-built system that was able to maintain DO concentrations at precise levels, reproductive performance was analyzed under 3.5 mg/l, 4.5 mg/l, 5.5 mg/l and a control of 7.5 mg/l of DO. A second experiment evaluated reproductive performance at 5.0, 5.7, 6.5 and 7.5(control) mg/L. Breeding attempts ceased altogether at 4.5 mg/l and lower. At higher concentrations, the effects of DO on reproductive output were contradictory between experiments. When DO was maintained at 5.5 mg/L in the first experiment, egg production was lower than in the controls. When DO levels of 5.7 mg/L were used in the second experiment, egg production was higher than in the controls. Courtship behaviour decreased significantly compared to the control at DO levels of 4.5 mg/L and lower. No significant differences were observed between treatments in morphometrics, survival, larval deformities, sex steroid levels, vitellogenin levels, hatching success, egg size, fertility, or gonad histology. The results of this study demonstrate that reproductive behaviour may represent a sensitive early marker of reproductive impairment in fathead minnows. Inconsistencies between the two experiments suggest a possible hormetic effect in response to depressed DO in fathead minnows. My results have important implications with respect to Canadian water quality guidelines and applications in the restoration of aquatic systems with lowered DO due to human activities.

▼ The oil sands, located in north-eastern Alberta, are one of the largest deposits of oil worldwide. Because the Alberta Environmental Protection and Enhancement Act prohibits the release of oil sands process-affected material into the environment, industry is storing vast quantities of tailings on mine lease sites. The oil sands industry is currently accumulating tailings waste at a rate of >105 m3/day, for which reclamation strategies are being investigated. Naphthenic acids (NAs) have been identified as the most toxic component of oil sands tailings as they are considered acutely toxic to a variety of biota, and are therefore a target contaminant for tailings pond reclamation strategies. Current literature based on Microtox® assays (marine bacteria Vibrio fischeri) suggests that lower molecular weight NAs are more toxic than higher molecular weight NAs. The following thesis involves the utilization of NA fractions and their relative toxicities to determine if NA toxicity is related to NA molecular weight. A previous study generated an oil sands-derived naphthenic acid extract (NAE), which was fractionated by distillation at stepped temperatures, yielding five fractions with increasing median molecular weights (Daltons). In the present study, the same extract and five fractions were utilized. To expand on the earlier characterization which involved a low resolution electrospray ionization mass spectrometry (ESI-MS), the whole extract and five fractions were analysed using electrospray ionization high-resolution mass spectrometry (ESI-HRMS) and synchronous fluorescence spectroscopy (SFS). Mean molecular weights were generated for each fraction, and an increase in molecular weight with increasing fraction number was confirmed. Respective mean Daltons and relative proportions for each fraction are as follows: 237 and 11.9 % (fraction 1), 240 and 32.3% (fraction 2), 257 and 33.4% (fraction 3), 308 and 16.8% (fraction 4), and 355 and 5.6% (fraction 5). When chemical analyses of fractions were compared, it was determined that structures contributing to increased molecular weight included increased cyclic structures (up to 7-ring structures), aromaticity (mono- and diaromatics), nitrogen, sulfur, and oxygen heteroatoms, and dihydroxy/dicarboxy compounds. In addition, characterization data suggested the presence of NAs exhibiting estrogenic structures. Following chemical characterization, NA fractions were subject to embryo/larval bioassays using two fish species: Oryzias latipes (Japanese medaka) and Pimephales promelas (fathead minnow). Endpoints evaluated were mortality, time to hatch, hatch length, and abnormalities. Results suggest that relative NA fraction toxicity is not related to molecular weight, as no trend relating mean Dalton weight to toxicity was observed for any endpoint in both species. Acute toxicity data indicated differences between fractions as high as 2-fold, although results were species-dependent. Fraction 1 displayed the lowest potency (highest LC50) for both Japanese medaka (0.291 mM) and…

▼ The global aquaculture industry is a multibillion dollar business that is threatened by pathogens, including a wide array of aquatic viruses. Currently there are no antiviral treatments available to combat viral outbreaks, and as such viral infection can cause vast economic loss. Two important species for aquaculture include rainbow trout (Oncorhynchus mykiss), destined for human consumption, and fathead minnow (Pimephales promelas), a common species grown for bait purposes. Double-stranded (ds)RNA is a potent immunomodulating molecule produced during viral replication; dsRNA treatment induces a robust antiviral state that makes host cells refractive to viral replication. This thesis explored dsRNA-induced innate antiviral pathways from two angles. Firstly, the differences in dsRNA-induced responses between virally-produced dsRNA, synthesized dsRNA with natural sequence variation, and synthesized dsRNA with a homogenous sequence were analyzed in rainbow trout cells. The dsRNA, regardless of source, was sensed at the cell surface by a common receptor in rainbow trout cells and induced an innate immune response and antiviral state against two aquatic viruses, viral hemorrhagic septicemia virus and infectious pancreatic necrosis virus; the virally-produced and lab-synthesized dsRNA molecules with natural sequence variation produced the most similar responses. The second angle of approach was to better understand the host’s response to exogenous dsRNA treatment. To this end, novel dsRNA sensors were identified and characterized in rainbow trout. This included class A scavenger receptors, the purported surface receptors for dsRNA, including MARCO, SCARA3, SCARA4, and SCARA5, as well as two novel cytoplasmic dsRNA sensors from the DExH/D-box family, DDX3 and DHX9. The receptors found in rainbow trout contained the same conserved domains that are found in their mammalian counterparts, a first indication of conserved functionality. Two MARCO variants were identified and found to bind to two gram-negative and one gram–positive bacteria, but surprisingly not to dsRNA. Rainbow trout DDX3 and DHX9 are both functional in their ability to bind to dsRNA. The culmination of these findings was the development of a dsRNA molecule with sequence variation that can act as a potent antiviral therapy in vitro in fathead minnow cells. The findings from this thesis demonstrate the importance of ‘natural’ dsRNA as an innate immune signalling molecule and its potential to function as a prophylactic antiviral therapeutic for fish.

▼ The fathead minnow (FHM, Pimephales promelas) is a species of temperate freshwater fish with a geographic range that extends throughout much of North America that is widely used as a model organism for aquatic toxicity testing. Our team at the Environmental Protection Agency produced a new FHM assembly which served as the foundation for accomplishing the aims in this project. Because of the importance of the underlying assembly to being able to achieve the aims, the generation of the new assembly is presented in this dissertation, though it was not a specific aim.The first aim of this research project was to annotate the protein coding genes in a new FHM genome. A comprehensive set (26,150) of gene models that can facilitate the analysis of RNA-seq expression profiles derived from exposures of P. promelas subjects to chemicals and other stressors was produced. The second aim of the project was to demonstrate the application and utility of the new gene models by using RNA-seq data generated in controlled exposure experiments to identify differentially expressed genes (DEGs) as markers of exposure. FHM were exposed to two chemicals with different modes of toxicity, the pyrethroid pesticide bifenthrin and copper. The new gene models were used to quantify mRNA expressions levels and statistical and machine learning techniques were applied to develop lists of DEGs in treated and untreated samples. The third aim of the study was to develop predictors of exposure from the data, using machine and statistical learning methods to combine the obtained markers into exposure signatures and optimize the predictive power of the resulting exposure classifiers. As part of these experiments, five different classifiers were evaluated using a cross-validation framework. Classifiers were able to distinguish treated samples from controls and were then applied to samples treated with the other chemical to evaluate how the classifiers performed when faced with an exposure scenario different from the one for which they were trained. Assessment of the genome and gene models in terms of both BUSCO coverage and RNA-seq mapping rates show that the new assembly and gene models represent not only a significant improvement over the previously published FHM assembly and gene annotations, but also that they compare very favorably with the highly studied and closely related zebrafish (Danio rerio). Given the mature state of the zebrafish genome the FHM results presented here represent a significant success story. Further validation of the success was provided by the successful use of the new gene models in the bifenthrin/copper exposure study. For each of the two toxicants studied, successful classifiers of exposure were able to be developed from a variety of approaches based on mapping RNA-seq data to the new gene models. Functional analysis of the differentially expressed genes (DEGs) leveraged by the classifiers indicated toxicant specific responses at the gene level appeared to drive the ability to correctly classify samples.

▼ Personality describes the consistent, individual differences in the behaviour we observe among human and non-human models alike. One of the components of human and animal personality which has sparked interest, is the boldness trait. Boldness is the propensity to engage in risk taking behaviour, and as such, has important ecological impacts on the interactions between animals. By changing the amount of risk taking behaviour, boldness effectively alters the outcome of predator-prey interactions. Boldness may alter a prey’s decision between an antipredator response or continuing other important behaviours (e.g. foraging or reproduction) when faced with a predator. The difference in response may be the result of a changed perception in the amount of local risk, or due to a differential amount of information gathered from the environment. In either case, more information about local predators increases the likelihood that a prey will appropriately respond to a threat. In aquatic systems, prey often receive chemical information from the scent of predators or chemical released by conspecifics. Specifically, alarm cues are released following damage to the skin tissue of many prey species and thus are reliable indicators of risk. These alarm cues are often the first line of prey defense, as they degrade slowly and are passed through the aquatic medium in currents. Secondary information regarding local risk often comes from the visual cues associated with the sight of a predator or frightened conspecifics. This provides prey with reliable information about risk since the transmission distance of visual cues is limited in water and further lessened by vegetation and turbidity. My experiment demonstrates that boldness in fathead minnows (Pimephales promelas) is stable over shorter temporal scales, and subsequently, affects how minnows acclimate to their environment and respond to visual and chemical information on local threats. In low risk environments, personality and turbidity strongly affect the threat-sensitive response of minnows. Shy minnows demonstrate no antipredator response when in turbid water and bold minnows elicit a strong fright response in turbid conditions. In clear conditions, the opposite occurs with large fright responses in shy minnows and no response in bold minnows. Conversely, when minnows were exposed to high amounts of environmental risk through the exposure to alarm cues, they all elicit strong fright responses regardless of personality or turbidity. This is the first experiment to investigate the complex interplay of personality and multiple cue types on the threat-sensitive response of prey fish.

▼ Salinization poses a threat to many inland aquatic ecosystems. Therefore, it is important to understand the potential implications of salinization on aquatic systems. Saline water bodies are prevalent in the Northern Great Plains of North America—an area that includes portions of Alberta, Saskatchewan, and several northern states in the United States. In this area, saline water bodies provide an environmentally important habitat for a variety of species. Salinization, both natural and anthropogenic, is predicted to increase in the Northern Great Plains in the future, but the potential effects on aquatic organisms remain largely unknown. To investigate these potential impacts, I first established lethal levels of salinity exposure in fathead minnows (Pimephales promelas), northern pike (Esox lucius), and walleye (Sander vitreus). This experiment also gave me a framework for determining relevant concentrations with which to test the effects of sub-lethal salinity exposure on fathead minnows. After deciding appropriate levels, I exposed minnows to one of three sub-lethal salinity concentrations crossed by one of three alarm cue concentrations—an indicator of imminent predation risk. I found that salinity reduced the overall intensity of antipredator behaviour in the highest salinity concentration, and also eliminated threat-sensitive responses at the intermediate salinity concentration. I then tested the effects of salinity on reproductive endpoints, both egg-based and behavioural, in fathead minnows. I found impacts on egg-based endpoints at all salinity levels, even the relatively low 1000 parts per million (ppm) concentration. I also found significant reproductive behaviour modification in the highest salinity treatment. I was then interested in determining an adequate acclimation point at which reproductive endpoints of minnows held in saline water matched those of minnows held in dechlorinated tap water. My data suggest that the acclimation point is approximately 14 weeks in 1000 ppm salinity, though it should be noted that my scope of inference may be limited by small sample sizes. Finally, I investigated second generation effects of minnows spawned, hatched, and reared in low-level salinity. I found no effect of salinity on morphology or antipredator responses.

▼ Previous studies at the Key Lake uranium mill (Saskatchewan, Canada) suggested the complex effluent discharged alters energetic stores of resident fish species. A second study at the same site demonstrated certain fish from lakes downstream of the mill produce larvae with elevated incidence of developmental deformities. The mechanisms by which energy homeostasis is affected in fish downstream of the Key Lake uranium mill are unknown, and the effects of deformities and altered metabolism on swimming ability have not been explored. Therefore, the overall objective of this thesis was to investigate whether effluent exposed fish exhibited differences in swimming performance and energy homeostasis. To achieve this objective two experiments were conducted. In the first experiment juvenile spottail shiner (Notropis hudsonius) were collected from a lake downstream of the Key Lake uranium mill, and compared to fish collected from a nearby reference lake. In the second experiment larvae were collected from laboratory raised fathead minnow (Pimephales promelas) exposed to 5% diluted uranium mill effluent or control (dechlorinated municipal) water, and reared in the same treatments to 60 days post hatch (dph). No gross deformities were observed in any fish, and only shiner collected from the exposure lake in the field experiment had enlarged heart ventricles relative to body size compared to fish from the reference lake. Swimming performance was similar between shiner from the exposure and reference lakes in the field study, but effluent exposure impaired swimming ability in 60 dph fathead minnow in the laboratory experiment compared to fish from the control water treatment. After swimming performance tests fish were considered fatigued and metabolic endpoints were compared to non-fatigued fish. In both non-fatigued and fatigued shiner, liver glycogen was significantly greater in fish collected from the exposure lake compared to the reference lake. There was no difference in liver triglycerides in non-fatigued shiner between lakes, but liver triglycerides decreased after swimming in the field study reference fish. Muscle energy stores were unaffected by site or swimming in the field experiment. Conversely, whole body triglycerides and glycogen were similar between treatments in non-fatigued fathead minnow in the laboratory experiment. Swimming significantly decreased whole body triglycerides in fathead minnow from both treatments, but whole body glycogen was unaffected. In the field experiment blood endpoints (hematocrit, plasma glucose, lactate) in fatigued and non-fatigued shiner from both lakes further supported the possibility of altered intermediary metabolism or blunted stress response in fish downstream of the Key Lake uranium mill. In the field study, shiner muscle citrate synthase activity (an indicator of tissue aerobic capacity) was similar between lakes, but muscle â–hydroxyacyl coenzyme A dehydrogenase activity (an indicator of tissue lipolytic capacity) was elevated. In contrast, laboratory fathead minnow whole… Advisors/Committee Members: Weber, Lynn P., Janz, David M., Niyogi, Som, Pietrock, Michael, Pollock, Michael S..

▼ To improve monitoring efforts and establish a guideline that is relevant to oil sands naphthenic acids, more information is needed to understand the composition of naphthenic acid components in raw OSPW and their role in determining toxicity. Commercial naphthenic acids have been used as a toxicological surrogate for naphthenic acids in raw OSPW. The primary objective of this research was to conduct a thorough source, pathway to receptor analysis for reproducing fish exposed to a commercial (Fluka) and an oil sands extracted naphthenic acid mixture. To improve the environmental relevance, reverse osmosis water was used to match water quality conditions in the Athabasca River. Steady-state naphthenic acid concentrations were achieved in the flow-through system design for both Fluka treatments. Naphthenic acid concentrations measured in the water were roughly half the nominal concentrations. The difference observed demonstrates the importance of measuring in-water concentrations in future toxicological assessments with oil sands naphthenic acids. This research is the first to apply high resolution mass spectrometry to detect and estimate the uptake of naphthenic acids in fish muscle tissue. Although the tissue estimates are semi-quantitative, the results are consistent with the current GC-MS method to analyse naphthenic acids in biological tissues. The reproductive and embryo-larval effects were more pronounced in fathead minnows exposed to the same nominal concentration (5 mg/L) of the commercial mixture relative to the oil sands extracted mixture. A significant decrease in cumulative egg production and larval survival and an increased deformity rate was observed in the commercial naphthenic acid exposure. No significant differences were observed in reproduction or embryo-larval development in the extracted naphthenic acid exposure. The results of the present study clearly demonstrate significant toxicological differences in population level endpoints between commercial and oil sands naphthenic acids. Toxicological data from commercial mixtures should not be used in the development of a water quality guideline for naphthenic acids extracted from raw OSPW. However, toxicological assessments with oil sands extracted mixtures are limited. Similar to the conclusion reported in the 1998 CEATAG review, currently there is insufficient information to recommend a water quality guideline for the protection of aquatic life for oil sands naphthenic acids.

▼ Municipal wastewater effluents (MWWEs) contain anthropogenic substances that can exhibit endocrine disrupting activity. These substances, which disrupt endogenous endocrine signalling, can impact normal fish reproduction and development and lead to effects that manifest at the individual and population level. In the Prairie provinces of Canada, increasing urban populations and industrial activities have resulted in greater water demand, and therefore, greater amounts of MWWEs released into the aquatic environment. Treatment plants often feature outdated technologies that inefficiently remove contaminants and when coupled with the increasing water demands, present a risk to receiving environments. The objective of this study was to utilize the 21-day fathead minnow reproductive assay to identify potential reproductive effects of MWWEs from Regina and Saskatoon. Fish were exposed for 21 days to 0 %, 10 % and 50 % of the effluents. Impacts on reproductive success (fecundity, fertility) as well as morphological, histopathological, and molecular/biochemical endpoints were assessed in male and female fish. Exposure to 10 % and 50 % Regina MWWE resulted in a significant decrease in fecundity compared to non-exposed minnows. There were significant differences in fecundity of minnows exposed to Saskatoon effluent, although the effect was not dose-dependent. Fertilization rate remained consistent regardless of treatment. Histological examination revealed a significant increase in proportion of spermatogonia and testicular degeneration in male fathead minnow testes in 50 % effluent concentrations compared to control minnows in both Regina and Saskatoon exposures. Increased oocyte atresia was observed in female minnows exposed to both Regina and Saskatoon 50 % treatment. No change in circulating sex steroid hormones (estradiol, 11-ketotestosterone) in male or female minnows was observed. Analysis of gene transcription revealed that exposure to Regina effluent induced ERα mRNA in female fathead minnows while exposure to Saskatoon effluent induced ERα in females and androgen receptor in males. No change in the expression of the vitellogenin was observed in any effluent-exposed group. The results from this study demonstrated that exposure to MWWE can impact the reproductive output and gonadal development of fathead minnows; however, due to the lack of change in key endocrine-related endpoints, it appears these effects are not due to estrogenic or androgenic compounds in the effluent. Additional work conducted by two parallel AIME studies supported this conclusion. Due to the complex nature of MWWE further work incorporating additional endpoints (i.e. behaviour), exposure lengths, and multi-seasonal studies would provide valuable insight regarding the biological impacts of MWWE.

▼ A wide variety of parasites are known to cause changes in host behaviour. The altered behaviours range from simple changes in features such as activity and phototaxis, to the creation of behaviours that are new, and often bizarre. In this study, I investigated the effect of a trematode parasite, Ornithodiplostomum ptychocheilus (Strigeidae; Diplostomidae), on the behaviour of its intermediate host, the fathead minnow (Pimephales promelas). The larval stage (metacercaria) of this parasite resides within the central nervous system, specifically the optic lobes. In fish, one of the main functions of the optic lobes is to receive visual stimuli from the retina and then coordinate the optomotor response (OMR). This response is an innate component of rheotaxis that plays an important role in motion detection, navigation and orientation. In an initial experiment, 16 wk-old metacercariae reduced minnow OMR by 42% compared to uninfected controls. However, in a follow-up experiment, it was 2- and 4- wk old metacercariae that caused the greater (39 and 41% respectively) decrease in OMR. Because 2- and 4-wk old metacercariae are not infective to birds (the next host in the life-cylce), alterations in minnow OMR at this time are unlikely to be a parasite adaptive. During this period, reduced OMR is more likely a result of pathology caused by developing larvae within the optic lobes. However, negative effects of infection on OMR performance persisted to 16 wk post-infection indicating the parasite-induced reduction in host performance could be an adaptive strategy to increase parasite transmission. Surprisingly, the magnitude of reduction in minnow OMR was only loosely linked to metacercarieae intensity. Although both low (<5 parasites/fish), and high intensities (>100) led to large decreases in OMR, intermediate intensities had only a small effect. Such non-linearity between intensity and the magnitude of host behavioural changes suggest that the mechanisms leading to altered host behaviours are varied, and complex.
