▼ Fish introductions, unlike many other clades, are often carried out purposefully. This is a worldwide practice, which has been ongoing since ancient times and has found new powerful ways to increase in magnitude and scope through the development of more effective transport and with increasing population wealth. Even though the literature is building up pace fast with this relatively recent phenomenon, information is still lacking on the mechanisms and results of the impact that introduced fish have on freshwater ecosystems. Remote small lakes at high-latitudes can be used to evaluate some of these impacts, as they are of limited size and often host relatively simple food webs with a single species of introduced fish, which makes them ideal model systems. Many areas are not as easy to investigate, as they present much more complex ecosystems where complex species interactions take place. For example, artificial lotic systems with a high number of species interactions can be particularly challenging to tackle as other anthropogenic/environmental stressors might be challenging to disentangle. This thesis focused on three main themes which addressed the reliance of introduced fish on terrestrial energy, their cascading effects on the food web and their interaction with native species. The first two themes used brown trout introduced in remote small lake ecosystems at high latitudes as a model, whereas the last theme used a complex lotic system at low latitudes where multiple species were introduced at different times. The chapters of this thesis used neo- and paleolimnological techniques to investigate the impacts of introduced fish, sometimes in combination. In particular, the first theme was tackled through the use of stomach content, fatty acids and stable isotopes to unravel the feeding ecology of introduced brown trout. The second theme was instead addressed through multiple paleo-proxies in combination with neolimnological analyses and models. The last theme was investigated through the analysis of long-term environmental and fish-assemblage data. Our findings suggest that terrestrial sources could be highly important in supporting introduced brown trout populations in small lakes at high latitudes. Despite challenges inherent to the turnover rates of fish liver and muscle tissues, which were longer than previously thought, this support did not vary across different years or fish densities, but was affected by seasonal factors over the course of the open-water season. Our results also suggest that introduced brown trout affect the food web of host lakes through trophic cascades, altering the abundance of pelagic and benthic micro- and macroinvertebrates, probably through a modification of the distribution of macro-invertebrate communities. According to a bioenergetic and a mass balance model, introduced brown trout nutrient regeneration should have increased lake productivity; however paleo-proxies indicated no such change but rather a shift from pelagic to benthic productivity. Finally, our results…

▼ Zooplankton are considered an important link between the zooplanktivores that consume them and the lower trophic levels, yet their specific ecological role in littoral brackish ecosystems is still relatively unstudied. In general, ecological interest in zooplankton derives from their roles as grazers or as a food source. As grazers, their role is coupled with predicting future densities and composition of the algal community, while alternatively as prey they provide information on fish stocks in terms of the zooplankton production available to fish. This thesis aimed to unravel aspects related to these roles in the littoral zones of the Baltic Sea, by shedding light on the themes of zooplankton composition and diversity, the interactions between zooplankton and their predators, and the general feeding ecology of components of zooplankton. The first objective of the thesis was to gain baseline information on zooplankton community composition and diversity in the littoral Baltic Sea via field sampling on a salinity gradient. The thesis also aimed to investigate how salinity and other abiotic factors, such as turbidity, temperature and wave exposure, affect zooplankton communities and the predation that structures them. Predation via two types of feeding by zooplanktivorous fish was studied experimentally as a regulator of zooplankton communities. Finally, the thesis investigated the role of copepod nauplii as grazers in laboratory conditions. Salinity was found to be the most significant abiotic driver of spatial patterns of composition and diversity of zooplankton. Turbidity/chl a also influenced community structure to a lesser extent. The spatial patterns of species heterogeneity remained relatively constant regardless of temporal turnover, and there was an abrupt change in species composition at an intermediate salinity of 4 (on the Practical Salinity Scale) on the salinity gradient. Functional diversity of zooplankton was found to be related to salinity, but also to factors related to productivity after a certain threshold. Zooplankton diversity was also affected by predation, but this effect was regulated by the initial composition of the zooplankton community, which was in turn directly related to seasonality. Predation itself was found to structure the community through direct removal of crustacean zooplankton, as well as cascading effects on microzooplankton. These effects, as well as the extent of the disturbance generated by turbidity on zooplanktivorous feeding, were all closely related to predator type. In the final section of the thesis, which concentrated on zooplankton as consumers, the functional responses of stage NII nauplii of the calanoid copepod Paracartia grani to various microalgae were found to be either Holling type II or III responses. Highest maximum clearance rates were found on a diatom and a dinoflagellate of a size of ~12 µm, indicating an optimal prey:predator size ratio of 0.08. In plurialgal mixtures, feeding patterns were largely dependent on prey type. Zooplankton are…

▼ Estuarine organisms, such as juvenile penaeid shrimp, experience fluctuating oxygen pressures on a daily basis. In coastal waters of the southeastern United States, severe hypoxia (< 4–6 kPa) is common in the summer, also a time during which bacterial concentrations in seawater are high. In response to invading bacteria, crustaceans mount an immune defense resulting in aggregations of circulating hemocytes. These aggregates can be trapped in and obstruct hemolymph flow through the gills, inhibiting oxygen uptake. Hypoxia itself is also known to inhibit immune function. In this study we investigated some key characteristics of penaeid shrimp that are likely to be associated with their ability to cope with hypoxia and bacterial infection. We compare critical Po₂, the oxygen pressure below which oxygen uptake depends on available ambient oxygen, in two commercially important shrimp species: wild Litopenaeus setiferus, the Atlantic white shrimp, and aquacultured Litopenaeus vannamei, the Pacific whiteleg shrimp. We also compare whole body lactate concentrations following acute exposure to severe environmental hypoxia (5.3 kPa), and injection with a sub-lethal dose of bacteria ( Vibrio campbellii 90-69B3), in aquacultured L. vannamei and in wild-caught Farfantepenaeus duorarum, the Atlantic pink shrimp. LD₅₀ tests indicate that the virulence of V. campbellii in L. setiferus (LD₅₀ = 6.4 × 10⁵ CFU g−1 shrimp) is similar to that previously determined in L. vannamei (LD₅₀ = 3.06 × 10⁵ CFU g−1 shrimp). We found no difference between L. vannamei and L. setiferus in critical Po₂, which fell between 3.5–5.2 kPa in both species. Whole body lactate concentration was measured in shrimp held in normoxia (>16 kPa) or hypoxia and injected with saline or bacteria. There were no effects of exposure in L. vannamei, however lactate concentration in F. duorarum increased by 60% in shrimp exposed concurrently to hypoxia and injected-bacteria, compared to saline-injected shrimp exposed to hypoxia and Vibrio-injected shrimp exposed to normoxia. This is consistent with previous findings in our lab, that hemocyanin in L. vannamei has a higher concentration and O₂ affinity, resulting in better tissue oxygenation, than that in wild species of Atlantic shrimp. These data suggest that aquacultured L. vannamei has an adaptive advantage over at least one species of wild penaeid shrimp in coping with hypoxia and bacterial infection.

▼ Natural and sexual selection shape animal communication signals according to the demands of social context and the environment, which results in enormous variation in signal properties. My dissertation uses the electrocommunication signals of South American weakly electric knifefish to compare signal structure across several closely related species, with particular emphasis on signals that are extreme or unusual. Weakly electric fish continuously generate an electric field using an electric organ discharge (EOD). During short-range social interactions, fish produce chirps by rapidly and transiently increasing EOD frequency. I used recordings with playbacks of conspecific signals and hormone manipulation to characterize the sexually dimorphic chirp duration of Parapteronotus hasemani, a species of electric fish with high-frequency, long-duration chirps and huge variation in male morphology. I also described signaling behavior in Distocyclus conirostris , a species of electric fish with a low-frequency EOD and an unusual asymmetrical behavioral response to “jamming” created when EODs of similar frequencies interact. Next, I compared across species to examine how signal properties (EODs and chirping) interact to influence each other’s detection and evolution. Certain signal parameters such as chirp frequency modulation and EOD frequency difference have substantial effects on chirp conspicuousness. Contrary to expectations, there was little support for a strict co-evolution in which a species’ chirps are most conspicuous on their own EOD waveforms. Thus, although EOD properties influence chirp conspicuousness, other factors such as the social or physical environment also likely shape chirp structure. Additionally, I show that EOD waveform may differ in perceptibility based on the EOD waveform complexity of the interacting fish. I consider how chirp conspicuousness could drive the evolution of sexually dimorphic chirps (such as those produced by P. hasemani), and I raise questions about whether low-frequency EODs (such as those produced by D. conirostris) contain sufficient information for fish to detect conspecific EOD frequencies using the neural mechanisms described in fish with high-frequency EODs. Taken together, these results show how the properties of multi-component signals shape each other and impact signal detectability. Finally, my dissertation concludes with a description of an innovative approach to teaching scientific communication skills in a highly structured undergraduate introductory biology lab.

▼ Arctic Grayling (Thymallus arcticus) are widely distributed on the Arctic Coastal Plain (ACP) of Alaska, and are one of the few upper level consumers in streams, but the trophic pathways and food resources supporting these fish are unknown. Grayling migrate each summer into small beaded streams, which are common across the landscape on the ACP, and appear to be crucial foraging grounds for these and other fishes. I investigated prey resources supporting different size classes of grayling in a beaded stream, Crea Creek, where petroleum development is being planned. The specific objectives were to measure terrestrial prey subsidies entering the stream, quantify prey ingested by Arctic Grayling and Ninespine Stickleback (Pungitius pungitius ), determine if riparian plant species affect the quantity of terrestrial invertebrates ingested by grayling, and determine if prey size and type ingested were a function of predator size. Results indicated that small grayling (< 15 cm fork length (FL)) consumed mostly aquatic invertebrates (caddisflies, midges, and blackflies) early in the summer, and increasing quantities of terrestrial invertebrates (wasps, beetles, and spiders) later in summer, while larger fish (> 15 cm FL) foraged most heavily on stickleback. Riparian plant species influenced the quantity of terrestrial invertebrates entering the stream, however these differences were not reflected in fish diets. This study showed that grayling can be both highly insectivorous and piscivorous, depending upon fish size class, and that both aquatic and terrestrial invertebrates, and especially stickleback, are the main prey of grayling. These results highlight the importance of beaded streams as summer foraging habitats for grayling. Understanding prey flow dynamics in these poorly studied aquatic habitats, prior to further petroleum development and simultaneous climate change, establishes essential baseline information to interpret if and how these freshwater ecosystems may respond to a changing Arctic environment.

▼ In large, seasonally dynamic and spatially complex watersheds, the availability and relative importance of various food resources for stream fishes can be expected to vary substantially. While numerous studies have attempted to uncover the trophic linkages that support stream salmonids, much of these efforts have occurred at small scales that disregard variability of food resources inherent in lotic systems. This study aimed to determine large-scale patterns in the contributions of freshwater, terrestrial, and marine-derived food resources to juvenile Chinook and Coho salmon (Oncorhynchus tshawytscha and O. kisutch) in the large, glacially influenced Susitna River, Alaska. I quantified diet patterns both spatially, across different macrohabitat types positioned along a 169-km segment of the river corridor, and temporally, from June to October, using stable isotope and stomach content analyses. To further resolve energy pathways from basal carbon sources to juvenile salmon, I determined the relative roles of terrestrial organic matter and freshwater periphyton food sources to aquatic benthic invertebrate diets. The latter analysis showed that invertebrate consumers were more reliant on freshwater periphyton than on terrestrial organic matter. Bayesian stable isotope mixing models indicated that juvenile salmon in the middle Susitna River were, in turn, largely supported by freshwater invertebrate prey regardless of spatial and temporal context. The relative contribution of marine-derived prey (salmon eggs) to juvenile salmon diets was greatest in the fall within tributary mouth and off-channel macrohabitats during both years of the study. Terrestrial invertebrate prey contributions were generally greatest during mid-summer within all macrohabitat types sampled, however this pattern varied across years. No upstream to downstream diet pattern was apparent from the data. These results underscore the importance of freshwater energy pathways for sustaining juvenile Chinook and Coho salmon in the Susitna River and provide further spatial and temporal context for the importance of pulsed marine and terrestrial prey subsidies. As Pacific salmon stocks continue to decline, management and mitigation efforts should operate on knowledge gained from studies that encompass the large-scale spatial and temporal variability inherent in riverine landscapes.

▼ Zygote arrest 1 (Zar1) is a maternal-effect gene that is essential for early embryonic development. Recently, a novel gene called Zar1-like (Zar1l) was discovered. Functional studies showed that Zar1l plays an important role in regulating oocyte-to-embryo transition in the mouse. The objectives of this study were to characterize the rainbow trout Zar1 and Zar1l genes and evaluate the potential roles of these genes in controlling egg quality in rainbow trout. Through database mining, we identified the cDNAs encoding rainbow trout Zar1 and Zar1l. The Zar1cDNA codes for a protein of 333 aa ,and the Zar1l cDNA encodes a protein of 323 aa. The sequences at the C terminus of the two proteins are highly conserved and contain a conserved Zinc-binding domain. Analysis of tissue distribution by RT-PCR showed Zar1 is predominantly expressed in ovary and testis with minor expression in other somatic tissues, while Zar1l is exclusively expressed in ovary. The expression patterns of Zar1 and Zar1l genes during early embryonic development (0h, 7.5h, 10.5h, 19.5h, 2d and 7d post fertilization) were determined by quantitative real-time PCR analysis. Both genes are highly expressed in unfertilized oocytes (0h), but they show different expression patterns. While the expression of Zar1 gene decreases from 0h to 10.5h post fertilization, and then increases in 2d embryos, the Zar1l gene shows continuous reduction of expression during early embryonic development (from 0h to 2d embryos). The expression patterns of Zar1 and Zar1l genes during ovarian development (pre, early, middle, and late vitellogenesis) were also determined by quantitative real-time PCR analysis. Both genes showed high expression in pre-vitellogenesis and reduced expression in early and middle vitellogenesis. In late vitellogenesis, expression of Zar1 gene increases again, but Zar1l gene expression continues to decrease. To determine the role of Zar1 and Zar1l genes in controlling egg quality, we analyzed the expression of both genes in eggs of different qualities (Day1, Day7, and Day14 post-ovulation). Both genes showed reduced expression in eggs of low quality. Finally, we performed a yeast-two hybridization screening to identify proteins that interact with Zar1l protein. Five proteins showing interactions with Zar1l protein were identified which include Di-N-acetylchitobiase, Serine/threonine/tyrosine-interacting protein (STYX), Ariadne-2 homolog, GH20 HexA HexB-like, and C-type mannose-binding lectin.

▼ In many cultured fish species, such as salmonids, gonadal development occurs at the expense of stored energy and nutrients, including lipids. Mobilization of intramuscular lipid during gonadal development decreases fillet quality. The aquaculture industry induces triploidy to generate sterile individuals; however, differences in lipid metabolism of female diploid (2N) and triploid (3N) trout may alter fillet quality. In addition, there is concern that genetic selection for increased growth negatively impacts fillet quality and muscle lipid content. Research in these areas would aid in the development of better management practices for efficient food-fish production that optimizes product quality.;The goal of this research is to assess the specific impacts of sexual maturation, polyploidy, and nutrition on growth responses, fillet quality attributes, and fatty acid content. Additionally, changes in gene expression of 35 genes within the regulatory pathways governing fatty acid metabolism of various energy stores were investigated to elucidate mechanisms regulating nutrient repartitioning during sexual maturation. Four studies were conducted to assess these variables. In the first study, effects of feeding level and polyploidy on fatty acid composition and metabolism of energy stores were considered. This study showed that ploidy had greater impact on fatty acid metabolism and composition of energy stores than moderately restricted diets at sexual maturation. A second study investigated changes in fatty acid metabolism of 2N and 3N female trout throughout sexual maturation. These data showed that there are no physiological differences between 2N and 3N females prior to 18 M of age; however, there are dramatic differences in energy store compositions and gene expression beginning at 20 M of age. In general, data indicate 2N fish have increased fatty acid beta-oxidation in white muscle that was associated with altered gene expression within the mTOR pathway and in visceral adipose tissue that was associated with increasedpparbeta expression. In contrast, increased expression of genes involved in fatty acid synthesis in 3N female liver appears to be associated with increased expression of PPARgamma as well as altered expression within the mTOR pathway, consistent with continued deposition of lipids in these fish. A subsequent study examined differences in fatty acid composition and gene expression between immature male and female rainbow trout. Females had higher muscle polyunsaturated fatty acid (PUFA) content; albeit, no differences were observed for other fatty acids measured. Gene expression data indicate possible increased fatty acid turnover in female trout muscle through increased expression of genes involved in both fatty acid synthesis and beta-oxidation. Male livers have higher expression of genes within beta-oxidation, which may contribute to the lower PUFA content. Lastly, to evaluate specific associations of fillet yield and fat content with differences in fatty acid metabolism, growth, fillet fatty acid… Advisors/Committee Members: P.

▼ This thesis examines habitat preference of yellow-phase American eels (Anguilla rostrata) and relationships between age and length with that preference. The thesis is comprised of two chapters: (1) an introduction and literature review on American eel life history, their habitat selection, and the study of resource selection, and (2) an experimental study of yellow-phase American eel habitat preference and relationships between preference and age and length. Given widespread habitat alteration of North American rivers, an understanding of the use and selection of habitat is important to conservation and management of the American eel. Yellow-phase American eels are often considered as habitat generalists, in part, because of their occurrence across a wide range of habitat types, but few experimental studies have examined microhabitat selection. In a laboratory experiment, I quantified microhabitat use of small yellow-phase American eels (n = 130, 224 – 338 mm TL) conditional on five benthic substrate types common to many rivers within the geographic range of the American eel. During nine, 4-day trials replicated with three aquaria, American eels were given a choice to burrow into five equally available benthic substrates: cobble (90 – 256 mm), gravel (4 – 16 mm), sand (0.125 – 1 mm), silt/clay (< 0.0625 mm), and leaf pack. Five American eels were used per aquaria for each trial, and individuals were used one time only. All eels were injected with PIT tags prior to the study, which allowed for determination of lengths and otolith-based ages of each individual following each trial. Leaf pack was selected with a significantly higher probability than other substrates (63 of 130 individuals). However, other substrates were also used (cobble, 21 of 130; silt/clay, 18 of 130; gravel, 16 of 130; and sand, 12 of 130). Length and age covariates were not associated with substrate selection. Selection of leaf pack habitat supports the importance of terrestrial organic material and riparian zones to yellow-phase American eels in riverine systems. Advisors/Committee Members: Stuart A.

▼ Assessments of watershed-based restoration efforts are rare. Monitoring of projects pre- and post-treatment are essential for the science of stream restoration ecology to advance. We took an experimental approach, following adaptive watershed management principles, to evaluate the effectiveness of watershed-based restoration efforts developed to maximize the ecological recovery of acid mine drainage (AMD) impaired streams. We sampled water chemistry, physical habitat, and benthic macroinvertebrate and fish community structure in 3 stream types: AMD (14 streams), AMD-treated (13 streams), and unimpaired reference (4 streams). Treatment technology implemented on impaired streams included in-stream active treatment dosers, limestone sand applications, and an at-source passive treatment system. Assessment sites were strategically selected based on treatment locations, and we evaluated conditions pre-treatment and 3 years post-treatment. Water chemistry varied widely. Sites impaired by AMD improved in water quality with AMD treatment. For example, dissolved metals and acidity declined but treatment waters remained elevated in sulfate and conductivity. Likewise, biotic conditions varied widely and sites impaired by AMD improved in bio-condition scores with AMD treatment. For example, EPT genera increased but were still low compared to unimpaired stream types. In addition, we found fish at 9 sites that previously had none. Community-level analyses indicated improved but altered assemblage of taxa at treated sites compared to untreated sites. Overall, general improvements in water quality and bio-condition at the stream-scale were associated with improvements in a measure of ecological value at the watershed scale. Our results suggest that unique communities driven by the new water chemistry signature are being formed. Only 3 years have passed since project completion and communities that reflect true reference may require more time. This general framework for adaptive watershed management developed for mined watersheds can also be applied to other anthropogenic impacted watersheds in this region. Applying an experimental approach towards restoration project assessments can facilitate restorationists and project managers to understand what types of treatment accomplish their goals.

▼ Trout fillets, subjected to refrigeration (4°C; 3 or 7 d) by frozen storage (-25°C; 0 or 30 d) combinations, were cooked; texture, determined by a novel, variable-blade (VB) attachment, was compared with a widely-used Allo-Kramer shear (AK) attachment to determined its sensitivity in detecting variation in fillet texture. Instrumental texture was related to sensory measurements to determine attachments' accuracy in assessing cooked fillet texture. Weight of raw fillets decreased after 30-d frozen storage. Fillet weight further decreased after cooking. Moisture content decreased while fat content remained constant. The AK attachment detected differences in energy of shear, which decreased after 30-d frozen storage. Shear force increased after cooking and could be detected by VB attachment. The VB attachment, in a perpendicular direction, demonstrated the effect of shear direction; force determined by this configuration correlated with sensory hardness and cook loss.;Fertile and sterile fish were chosen as a model to describe key contributors to fillet texture. Two sets of 60 diploid (2N; fertile) and triploid (3N; sterile) females were harvested at 6 age endpoints (16, 18, 20, 21, 21, and 24 mo). From November 2008 (20 mo) to January 2009 (21 mo), GSI of 2N females increased substantially and their growth were at equal rate to those of 3N females. By November 2008, 2N females had a lower muscle fat content and higher moisture content than 3N females. Shear force negatively correlated with fillet fat content. Regardless of ploidy, raw fillets were softer between November 2008 and January 2009. Alkaline-insoluble hydroxyproline (a-i HYP) content of 2N muscle increased substantially in March 2009 (24 mo), and this response was consistent with increased energy of shear (g*mm). In March 2009, denaturation peaks (Tmax) of actin from 2N females were higher than those observed in 3N females (78.17 v. 77.27°C). Muscles of 2N fish were more elastic than those of 3N fish in a thermal scan ranged from 35-40°C. At temperatures greater than or equal to 45°C, muscle from younger (16 mo) fish was more elastic than older fish (18-24 mo). Lipid accumulation, observed primarily in 3N females, may lubricate and soften muscle fibers, and protect them from losing functionality at spawning when animals are on a high plane of nutrition.;Lastly, the VB was compared to the AK attachment for (1) its sensitivity in discriminating texture variation and (2) its predictability in relating texture parameters to alkaline insoluble HYP content. In the maturation study, the VB detected effect of age endpoint on cooked texture; minimum firmness was observed in January compared with December and March. In the storage regimen study, regimen*cooking state affected fillet texture; AK detected effect of 30-d frozen storage on raw texture; whereas, VB detected this effect after cooking. In both studies, VB texture was not correlated with collagen insolubility; the finding may have been due to limited sample size and range of variation in… Advisors/Committee Members: P.

The rate of green house gas emission is accelerating, with current trends exceeding those predicted by “worst case” global climate change scenarios. The chemistry of the ocean is fundamentally changing as a result of increasing atmospheric CO₂, which dissolves in seawater, making it more acidic, a process referred to as ocean acidification (OA). A rapidly expanding body of science is now being generated to understand the impact of this global environmental change. To date, most studies evaluating OA effects have centered on simplified laboratory analyses that expose single populations to short-term treatments in order to quantify responses of individuals. These designs offer a limited assessment of the degree to which phenotypic plasticity and local adaptation might influence the response of populations to OA. To address these questions, I carried out studies on members of Phylum Bryozoa, a species-rich clade of calcified colonial marine invertebrates distributed throughout the global ocean. Bryozoans were selected as a model system for this work because the clade exhibits a broad array of growth and calcification strategies, and because of the relative paucity of data regarding their expected response to future acidification. In addition, bryozoans can be subdivided into genetically identical replicate clones, which can then be assigned to separate treatments, allowing variation across treatments to be uniquely partitioned into the variance components of statistical models. In order to culture bryozoans for comparative experiments, I designed and constructed a new flow-through OA system at the Bodega Marine Laboratory, capable of finely manipulating both the temperature and carbonate chemistry of seawater, allowing for controlled laboratory experiments of long duration. In Chapter 1, I performed a comparative 9-month laboratory experiment examining the effects of ocean acidification on the native Californian bryozoan Celleporella cornuta. C. cornuta was sampled from two regions of coastline that experience different oceanographic conditions associated with variation in the intensity of coastal upwelling. Under different CO₂ treatments, the biology of this bryozoan was observed to be remarkably plastic. Colonies raised under high CO₂ grew more quickly, invested less in reproduction, and produced skeletons that were lighter compared to genetically identical clones raised under current atmospheric values. Bryozoans held in high CO₂ conditions reduced their investment in skeletal carbonate, changed the Mg/Ca ratio of skeletal walls and increased the expression of organic coverings that may serve a protective function. Differences between populations in growth, reproductive investment, and the frequency of organic covering production were consistent with adaptive responses to…

▼ West Virginia places an emphasis on fishing as a way to increase nature-based tourism. However, heavy fishing pressure on public water and unequal fishing effort at stocking locations can lead to declining catch rates and an increasing number of visitors that experience catch deprivation and dissatisfaction. Controlling access to streams is one approach to dealing with this carrying capacity issue. Both public and private land managers have approached this problem differently using various levels of control. For example, Pipestem State Park managers provided anglers with access to the Bluestone River with few controls via an aerial tramway prior to 2009. In recent years, the park has controlled access by stocking trout at the beginning of the shoulder season (November-April) when the tram is closed, thus limiting access to the river via a strenuous 4 mile hike on steep terrain. At Harman's North Fork Cottages, access is controlled on private land. Only guests that stay in the luxury log cabins are given easy and nearby access to a stocked segment of river. The purpose of this study is to compare the success, satisfaction, and perceived crowding of four stream fishing venues that fall along a spectrum of access from completely open access to closed, invitation only access. A total of 154 adult anglers completed an on-site interview. Indicators of fishing success (e.g., Catch Per Unit Effort) and economic impact of stocking strategies will be compared among the fishing venues. Catch Per Unit Effort values were found to be significantly different from one venue to another, while acceptability of catch was found not to be. The catch rate normative curve developed from this information is included, which shows the preferred and minimally acceptable catch rates for each different fishing venue. Additionally, significant differences were found in the number of anglers observed fishing on the stream by other anglers is reported, as it addresses the issue of perceived crowding and social carrying capacity.

▼ There are 27 species of sturgeon worldwide and most are currently extinct, endangered or threatened. Lake sturgeon, Acipenser fulvescens, one of the oldest species on the planet, evolved about 136 million years ago, and have had little morphological change, and are endemic to the freshwater lakes and rivers created by receding glaciers of the Laurentian ice sheet. Lake sturgeon have seen immense habitat loss due to human development and industrialization has nearly decimated populations. Changes to water and habitat quality, along with overharvesting, have caused declines to nearly 1% of their original population size. The Huron-Erie Corridor (HEC), includes the St. Clair and Detroit rivers that connect the upper and lower Great Lakes. This area in particular has experienced adverse effects over nearly 200 years of human activities, including the removal of spawning habitat to accommodate shipping traffic. Conservation efforts include regulations, endangered species listing, and habitat reconstruction. The creation of artificial reefs may be a sustainable management option by allowing the fish to increase their population sizes naturally. Three artificial reefs were built in the HEC in hopes of replacing spawning habitat. To verify the success and efficacy of the artificial reefs, genetics were used to determine the source and numbers of adult lake sturgeon spawning on the reefs and to determine if genetic diversity is maintained in their offspring. The maintenance of genetic diversity is required to expand population sizes and prevent negative side effects, such as the founder effect, in future generations. Eggs were collected from each reef and hatched into larvae in the lab. DNA was extracted from larval tail clips and PCR was performed to amplify 12 microsatellite loci. The samples were run using a capillary electrophoresis to obtain allele sizes at each locus for each individual. Their genotypes were then compared to 22 previously studied adult lake sturgeon populations in the Great Lakes to determine where the parental population came from. The effective population sizes for each reef were calculated to determine how many adults successfully spawned on each reef. The larval genotypes were then compared to the source population to determine if there were any losses in genetic diversity by calculating observed heterozygosity, allelic richness, and inbreeding coefficients that are indicative of the founder effect. The St. Clair and Detroit River adult populations were found to be the source parental population for the larvae collected on all three artificial reefs. There were large numbers of contributing adults when compared to total population sizes within the Great Lakes. There was no loss in genetic diversity in the larval samples compared to their parents, and therefore no evidence of the founder effect. This supports continued protection of lake sturgeon spawning habitat as well as the construction of additional reefs in the HEC. Advisors/Committee Members: Amy Welsh, Patricia M. Mazik, Edward F. Roseman.

▼ Reproductive biology and early life history data are important for understanding the ecology of fishes, and can be used for the management and conservation of rare species. During 2008 – 2012, a captive propagation study was conducted on Crystallaria cincotta (Diamond Darter), a rare species with a single extant population in the lower Elk River, WV. Also, captive propagation studies were conducting during 2008 on three species of darters of the subgenus Nothonotus: Etheostoma wapiti (Boulder Darter), E. vulneratum (Wounded Darter), and E. maculatum (Spotted Darter). Water temperatures during Diamond Darter spawning ranged from 11.1 – 23.3°C. Females and males spawned with quick vibrations to bury eggs in fine sand in relatively swift clean depositional areas. Egg size was 1.8 – 1.9 mm, and embryos developed within 7 – 11 days. Diamond Darters were 6.7 – 7.2 mm TL at hatch. Larvae ranged from 9.0 – 11.0 mm TL following a 5 – 10 day period of yolk sac absorption. Larvae were provided Artemia nauplii, Ceriodaphnia dubia neonates, Brachionus rotifers, and powdered foods (50 – 400 microns). Diamond Darter larvae did not feed in captivity, except for cannibalizing other larvae. Larvae survived for a maximum of 11 days. Larvae had relatively large gapes and teeth, suggesting possible larval piscivory and a need for alternative food sources during captive propagation. During the Nothonotus study, the length of spawning period and associated range of water temperatures for the Wounded Darter (89 days, 16.0 – 24.0°C) exceeded those of the Spotted Darter (46 days, 17.0 – 22.5°C) and Boulder Darter (48 days, 17.0 – 22.5°C). Eggs produced per female were least in the Boulder Darter (163), intermediate in the Spotted Darter (191), and highest in the Wounded Darter (345). Diameters of eggs at deposition and prior to hatch were least for Spotted Darter (1.9 – 2.0 mm, and 1.9 – 2.1 mm), intermediate for Wounded Darter (2.1 – 2.2 mm, 2.4 – 2.5 mm), and largest for Boulder Darter (2.2 – 2.4 mm, 2.4 – 2.6 mm). Lengths of larvae at hatch and at the start of first fin development varied in a similar pattern: Boulder Darter (8.5 – 9.1, 14.0 – 15.0), Wounded Darter (7.7 – 8.0, 13.5 – 14.0), and Spotted Darter (6.5 – 7.0, 12.0 – 13.0 mm). Overall production per female was lowest in Boulder Darters (61 juveniles/ female), intermediate in Spotted Darters (86 juveniles/ female), and highest in Wounded Darters (90 juveniles/ female).

▼ Three aspects of a bioenergetics model were examined for brook trout (Salvelinus fontinalis) in the laboratory: (1) refinement of the metabolism parameter estimations, (2) calculation of activity rates and (3) subsequent validation of the brook trout model. An integral part of bioenergetics modeling is the initial inputs of predator and prey energy density from body composition estimations. We present bioelectrical impedance analysis (BIA) as a means of rapidly estimating body composition in fish and then adjusted variables that may affect these predictions. We also used this tool and applied it to a compensatory growth study. Brook trout (Salvelinus fontinalis) were randomly split into 3 groups (N = 8) with each group having a different feeding regime (starved, compensatory or ad libitum). Changes in weight, gross growth efficiency, and body composition were measured repeatedly on individual fish using standard laboratory measures as well as bioelectrical impedance analysis (BIA) to determine if (1) compensatory growth occurred and (2) if the weight changes were energetic.;In 31 day bioenergetics experiments, final weights were underestimated by 4.5% (+/-11.06%, 95% confidence limits) and consumption was overestimated by 8.3% (+/-16.42%, 95% confidence limits). Bioelectrical impedance analysis models built with brook trout (Salvelinus fontinalis) were linear with strong validation group correlations (R2 > 0.86) for water, protein, fat and fat-free and dry weights. Temperature affected predicted estimates of total body water, dry weight and total weight linearly, but when data was normalized by weight, the temperature term was effectively canceled out. Gut-fill did not effect BIA predictions of any body composition parameter estimate while electrode placement did. Bioelectrical impedance analysis and standard compositional analysis determined that weight gains were energetic due to increases in protein, dry mass and fat, and not due to non-energetic gains (water). Furthermore, BIA found no significant differences in compositional changes between the treatment and control groups throughout the experiment. Advisors/Committee Members: Kyle J. Hartman..

▼ This thesis examines the thermal tolerance based on how expression of Heat Shock Protein (HSP) 70 and HSP90 differ between two different strains of rainbow trout (Oncorhynchus mykiss), the Case Western strain and the Kamloops strain, and determines if cortisol levels affect HSP expression in red blood cells. The Case Western strain is considered the only warm water trout, only recently was any aspect of its thermal tolerance quantified. Porto (2012) determined critical thermal maxima (CTM) for the Case Western strain and found it to be about 0.15 °C higher than the Kamloops strain. This thesis is comprised of three chapters: (1) an introduction and literature review on the biological history of these two strains of rainbow trout, on studies related to HSPs expression as indicators of thermal tolerance, and studies on the relation between cortisol expression and HSPs expression; (2) an experimental study investigating the differences between HSP70 and HSP90 between the two strains, before and after a heat stress test and between individuals of different sizes; (3) an experimental study investigating the relation between the heat stress protein expression and cortisol levels pre- and post-stress. The results on the HSP70 and HSP90 relative expressions confirm that Case Western strain has higher thermal tolerance, highlighting the importance of this strain as a candidate to be cultured in aquaculture facilities as an answer to possible impacts of future climate changes. Earlier studies suggested HSP expression varied with age in rainbow trout, but failed to consider strain-specific differences. Our results show that age-specific HSPs expression is not species-specific in rainbow trout as it differs by strain. The results show that the plasma cortisol levels before and after thermal stress do not differ among strains, and that the physiological response to heat stress is species-specific. The variable that has the largest influence on the variance expressed among groups came from the HSP90 gene. We found the stressed Kamloops was the most diverse group, with less thermal tolerance, influenced mostly by the weight of the HSP90 on the total variance. Advisors/Committee Members: Kyle J.

▼ This thesis involved two components: identification of the parasite Anguillicola crassus in American eels, Anguilla rostrata and PIT tag retention in eels in a laboratory setting. The recent spread of the swim bladder nematode parasite, Anguillicola crassus, in American eels has caused concern among biologists and fishery managers. A total of 244 yellow-phase American eels were collected at the Millville Dam eel ladder on the Shenandoah River, WV. Swim bladders were removed and examined for the presence of the nematode parasite. The number of parasites in each eel was recorded, and prevalence, intensity, and mean intensity were calculated. A swim bladder degenerative index (SDI) was also used on a subsample of 50 eels to document previous infections and the health state of the swim bladder. Prevalence of the parasite was 2%, and both intensity and mean intensity were 1. Based on the SDI, 38% of the eels showed signs of a previous infection of A. crassus. None of the eels from the Shenandoah River had severely degraded swim bladders, 38% had moderately damaged swim bladders, and 62% had healthy swim bladders. This is the first study that confirms the presence of A. crassus in the Potomac River watershed and the first to document the parasite in West Virginia. For the second part of the thesis, retention rates of passive integrated transponders (PIT tags) were compared among three tagging locations of small (205-370 mm) American eels: the dorsal musculature behind the head, the dorsal musculature near the dorsal fin origin, and the abdominal cavity. Eighteen American eels from the Shenandoah River, WV were PIT tagged in the three locations and tag retention was measured for a total of 9 weeks. Tag retention was highest in the dorsal musculature (100%) and in the abdominal cavity (100%), and lowest behind the head (88%). These results are consistent with previous literature. This research was a pilot study to determine PIT tag placement for a study of upstream migration in American eels. Advisors/Committee Members: Stuart A Welsh.
