Article
Soft plastic lures (SPLs) may comprise a significant amount of fishing gear pollution, yet little is known about their environmental impacts in aquatic systems or their ingestion by fish. We tested whether shape and material composition of ingested SPLs influenced subsequent prey consumption by Largemouth Bass Micropterus salmoides after SPL ingest...

We investigated the environmental life history of widely distributed threatened and endangered sturgeons in large rivers of the central United States that experience different regulatory regimes and management priorities. Using microchemistry techniques, our goal was to assess how to improve species conservation by dampening the incongruity that of...
Article
River modifications have altered critical habitats for fishes at a variety of spatial scales and caused global declines of many fluvial species. At small spatial scales (<1 m2), alluvial sand dunes, a ubiquitous habitat in highly modified rivers, are thought to provide energetic relief for benthic fishes in energetically costly riverine landscapes...
Article
Identifying the appropriate scale at which habitat is biologically relevant to riverine fishes in large, sand-dominated rivers is a challenge. Alluvial islands are important to several of these fishes throughout the central USA, but there is a paucity of information on island habitat features that restoration efforts should try to replicate. We det...
Article
In response to declines in coarse woody habitat (CWH) and fish productivity in natural lakes and reservoirs, agencies and stakeholders have used woody and artificial habitat enhancements to slow or reverse the effects of habitat loss from aging or shoreline development. Given that natural lakes and reservoirs differ in physical and biological condi...
Article
Artificial habitat structures are used to mitigate habitat loss within aquatic ecosystems and to increase angler catch rates; however, the potential trophic outcomes of concentrating fish at structure additions are rarely evaluated. We compared fish and fish prey assemblages between reservoir coves with and without newly added offshore habitat stru...
Article
Full-text available
Black carp (Mylopharyngodon piceus), a large molluscivorous cyprinid native to eastern Asia, has become established in the Mississippi River basin in North America. The vulnerability of most North American snails and bivalves to black carp predation remains unknown, especially as it relates to juvenile black carp transitioning to mollusk prey. We c...
Article
Successful stocking of Muskellunge Esox masquinongy into reservoirs is hampered by a variety of stressors that can affect post‐stocking survival, such as elevated pH conditions common to eutrophic waterbodies. We quantified Muskellunge survival, behavior, and physiological responses during a simulated stocking event where age‐0 Muskellunge were net...
Conference Paper
Full-text available
Lakes and reservoirs are aging with associated declines in structural habitat and fish production. In response, management agencies and stakeholders have used a suite of woody and artificial habitat enhancements to slow or reverse aging effects. However, variability in the types of structures used and differences in the physical and ecological cond...
Article
The relationship between magnitude of reproduction and adult density of pelagically‐spawning carp (PSC) species (Hypophthalmichthyes species, Ctenopharyngodon idella, and Mylopharyngodon piceus), and the influence of environmental factors on this relationship, is valuable information for management and control of these highly invasive cyprinids. Si...
Article
Black Crappie Pomoxis nigromaculatus and White Crappie Pomoxis annularis have contrasting patterns of performance along a gradient of turbidity for reasons that have yet to be elucidated. We examined how distinct, habitat‐linked morphologies of these congeners make Black Crappie more specialized for structurally complex vegetation and White Crappie...
Article
Full-text available
Fish herding (driving fish into nets) is used by commercial fishers to increase harvest of invasive bigheaded carp (Hypophthalmichthys spp.), yet has not been widely adopted for fisheries monitoring purposes. We conducted an experiment to assess whether fish herding using percussive sound or electrical stimuli can enhance catch rates and detection...
Article
The establishment of Bighead Carp Hypophthalmichthys nobilis and Silver Carp Hypophthalmichthys molitrix throughout the Mississippi River basin potentially expands the prey base for native predators. A mechanistic understanding of interactions between non‐native prey and native predators is needed to assess the potential for predator regulation of...
Article
Full-text available
Sympatric congeners with similar physiological and morphological characteristics may appear to overlap in niche space but respond to environmental change in different ways leading to population decline of one species while the other remains stable. Understanding why sympatric congeners vary in their ecological success can be challenging, but is par...
Article
Many fishes are planktivorous during early life and switch to piscivory or consume larger food items as ontogeny progresses. In contrast, paddlefish start as particulate feeders and later become filter feeders. Few studies have identified food items essential for paddlefish growth, survival and recruitment surrounding this ontogenetic diet shift. T...
Article
Extensive research has been conducted on Silver Carp Hypopthalmicthys molitrix in the heavily modified Illinois River in the midwestern United States due to the potential for populations to enter the Great Lakes; however, little research has been conducted on populations in unimpounded rivers. The Wabash River is an unimpounded large river in the U...
Article
Because different fishing gears may introduce different degrees of bias, we set out to compare two active sampling methods (alternating current (AC) and pulsed direct current (DC) boat electrofishing) and one passive method (modified fyke netting) in sampling sportfish in a midwestern US reservoir. Currently, the Illinois Department of Natural Reso...
Conference Paper
The pallid sturgeon Scaphirhynchus albus is endemic to the Missouri and Mississippi River drainage, though populations of this species have declined significantly due to overexploitation and anthropogenic degradation of these rivers. The pallid sturgeon has experienced substantial declines because of similar appearance to its congener, the shovelno...

Thermal variation has profound implications for the physiology and life histories of ectotherms, influencing individual performance and population dynamics. Aquatic ecosystems are especially strongly affected by alterations in the thermal environment. Coffeen Lake, a cooling source for a central Illinois coal-power plant, has temperatures in excess...
Conference Paper
Coffeen Lake, a cooling reservoir in central Illinois, receives thermal effluent from an Ameren Energy Co. coal fire power station. The goal of this project is to assess the impact of thermal effluent on sportfish distribution and to determine an effective sampling time for this reservoir. Sampling was done during fall, winter, spring, and summer,...
Conference Paper
Catfish are one of the most important fish harvested for human consumption in Midwestern waters. Channel catfish (Ictalurus punctatus), in particular, are one of Illinois most highly prized game and food fish. The Sangamon River, located in Macon County, is a lightly exploited system, as commercial fishing is not allowed except from Belt Route 48 s...
Conference Paper
A site specific rule change granted by The Illinois Pollution Control Board to Ameren Energy Generating Co. allows increased thermal loading in May and October on Coffeen Lake, a reservoir utilized by a power station capable of generating 945 megawatts of electricity. The goal of this project is to monitor the biological impacts on the sport fish p...

Our project goal was to evaluate a range of active and passive sampling gears to better sample and monitor juvenile and adult Asian carp in large river ecosystems.
