Sport fish consumption advisory for West Virginia
The risk based sport fish consumption advisory protocol, West Virginia Sport Fish Consumption Advisory Guide (the Guide), was drafted for the state. Fish were collected from ten West Virginia sites (5 previously identified as contaminated, 5 previously identified as uncontaminated). Fish samples …

The Consequences of Non-Native Species Invasions on the Contemporary and Historic Trophic Ecology of Native Sport Fish in a Lake Michigan Embayment
… influence on resource partitioning in nearshore fish communities. Here we use stable isotope analysis to characterize the contemporary fish community and historic walleye (<em>Sander vitreus</em>) population of Lake Michigan’s Little Bay de Noc. We found species-specific differences in the …

The biological effects of artificial reefs in Smith Mountain Lake, Virginia
… effects on the aquatic ecosystem. Virtually all sport fishes were attracted to the reef areas. The frequency of sport fish on the reefs generally coincided with their overall abundance in the reservoir. Sunfishes (Lepomis spp.) and white catfish were the most common. Centrarchid basses were also …

Biotic Integrity and Northern Pike Ecology in Eastern South Dakota
… increased agricultural production. Understanding sport fish ecology in prairie streams, garners important public support for protecting stream biotic integrity. Thus, our objectives were to (1) develop a fish IBI and validate reference sites, and (2) quantify the age, growth, and diet of the …

EFFECTS OF THERMAL STRESS ON SURVIVORSHIP OF BROOK TROUT (SALVELINUS FONTINALIS) IN ADIRONDACK LAKES
… to the Arctic Circle. These popular, coldwater sport fish face an uncertain fate in light of several climate change scenarios. Assessing the potential influence of variable temperature on brook trout populations poses an important challenge to fisheries biologists. I conducted a robust design …

Exploring the Behaviour and Physiology of Juvenile Bonefish (Albula vulpes): Fundamental and Applied Perspectives
… despite recent degradation, are home to many fish species, some of which are juveniles of economically important fish in recreational fisheries. Bonefish (Albula vulpes) are one such example of a recreationally important sport fish throughout the Caribbean; to date, most research has focused …

Space Use by Piscivorous Birds, Fish, and Humans on a Multi-Use Lake in Southern Saskatchewan
… to understand how economically important fish species (walleye Sander vitreus; northern pike Esox Lucius; and burbot Lota lota) use lakes and identify key areas for protection and management efforts. Conflicts between humans and fish-eating birds over fisheries resources have also emerged …

Influence of Gizzard Shad on Fish Community Ecology in Northeastern South Dakota Glacial Lakes
<p>Walleye Sander vitreus are the most popular sport fish in South Dakota, while yellow perch Perca flavescens are important both ecologically as prey for walleye and economically as an important sport fish themselves. Gizzard shad Dorosoma cepedianum are also an ecologically important species in …

The Contribution of Missouri River Reservoir Side-Channel and Floodplain Habitats to Mainstem Fish Populations: The Effects of Losing Connectivity Between Hipple Lake and Lake Sharpe
… are thought to be crucial habitat for prey and sport fish. Hipple Lake, the only warm-water floodplain embayment in Lake Sharpe, is in danger of losing connectivity to the reservoir because of sedimentation resulting from the 2011 flood. To evaluate Hipple Lake’s natal and adult contribution to …

Fish and decapod community structure in estuarine habitats of the New Orleans Land Bridge, including a description of the life cycle of tarpon (Megalops atlanticus) in southeastern Louisiana
… During 24 consecutive months, I collected 65,000 fishes and decapods comprising over 65 species from the New Orleans Land Bridge, an estuarine salt marsh. My research details the distribution of nekton across five contiguous but geomorphically different regions, which I defined as “Areas”. This …

Productivity and Trophic Interactions in the Missouri River Impoundments
… monitoring is a vital component of fisheries assessment in Missouri River impoundments. In South Dakota, annual variation in fish growth and abundance is used to monitor changes in fish populations and develop strategies (i.e. regulations) for managing recreational fishes. Although …

Feeding Ecology and Factors Influencing Growth and Recruitment of Channel Catfish in South Dakota Reservoirs
Channel Catfish Ictalurus punctatus are a major sportfish in the Missouri River basin, and despite being one of the most abundant species in South Dakota rivers and reservoirs, the impact of Channel Catfish populations and factors that influence their dynamic rates are not known. To address the …

Reservoir Management Techniques to Enhance Biological Productivity and Protect Water Quality
… step towards a larger goal to ultimately enhance sport fish production. The first year of monitoring occurred in 2011 and served as a control year for the three lakes. Treatments were initiated in two of the lakes (Lakes Rayburn and Norwood) in the second year, as one lake (Lake Brittany) remained …

Predation, turbidity, and other factors influencing juvenile Salmonid survival in the lower Snake River
… walleye (Sander vitreus) and channel catfish (Ictalurus punctatus). Consumption information is crucial because the construction of the Snake River hydrosystem has created a series of reservoirs, which have altered the river 's flow regimes, riparian vegetation, and turbidity. Further, …

The importance of density-dependent mechanisms in determining cohort survival in largemouth bass
Understanding factors important to recruitment in fishes has proven to be a difficult and challenging problem. Largemouth bass Micropterus salmoides, a popular recreational sport fish, is an excellent model species to explore mechanisms of recruitment, because both density-dependent and independent …

Analysis of the Trophic Support Capacity of Smith Mountain Lake, Virginia, for Piscivorous Fish
… (realized demand) of the two most popular sport fish in the system, striped bass (Morone saxatilis) and largemouth bass (Micropterus salmoides). The striped bass population consumed 46 kg/ha of alewife and 27 kg/ha of gizzard shad annually. Largemouth bass ate 9 kg/ha of alewife and 15 …

Bluegill Reproductive Biology and Population Dynamics in Four South Dakota Impoundments
… is an important prey species and important sport fish. Therefore, knowledge of reproduction and subsequent recruitment is essential for fishery biologists. Bluegill are typically considered multiple spawners. Protracted reproduction is likely a response to various environmental factors and …
