Fate and transport of Asian carp eggs in spawning rivers
In recent years the population of Asian carp has increased exponentially in the Mississippi River Basin. This invasive species are filter feeders that consume phytoplankton and zooplankton thus competing directly with native species as their diets overlap. Asian carp can lay thousands of eggs and …

Predator recognition and anti-predator behavior in juvenile Asian carp
… Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) widespread invasive fishes, and can be vulnerable to predation during their first year. Because they now overlap the niches of many native prey species, they may shoal with these species and learn about predation while doing so. …

Prey preference for Asian carp and soft plastic lure ingestion by largemouth bass
… bighead (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix) have become established throughout much of the Mississippi River basin. In many areas, these two species comprise a significant proportion of the fish biomass. Despite their prevalence and potential for negative …

Nearshore zooplankton communities of Lake Michigan and implications for invasibility by Asian carp
… alter the ability of invasive species, such as Asian carp, to establish self-sustaining populations. Without knowledge of spatial characteristics of zooplankton communities, it is difficult to assess the potential for Asian carp establishment. We sought to better describe spatial heterogeneity …

Zooplankton response to Asian carp harvesting in Illinois River backwaters: a natural experiment
Since the 1980’s, Asian carp (Hypophthalmichthys nobilis and Hypophthalmichthys molitrix) have spread throughout the Mississippi River basin and are now approaching Lake Michigan and the Great Lakes. This poses a problem because Asian carp can have major negative impacts on the zooplankton that …

FISH MEAL AS A POTENTIAL END USE OF INVASIVE ASIAN CARP FROM THE ILLINOIS RIVER
Subsidized harvest of invasive silver carp Hypopthalmichthys molitrix and bighead carp H. nobilis (collectively referred to as Asian carp) from the Illinois River have been initiated in an effort to control their populations. However, market-driven control strategies have been suggested in an …

Geographic expansion and small stream use by three species of invasive Asian carp in Illinois
Grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (H. molitrix), are three species of Asian carp that were intentionally introduced into the United States in the 1960s and 70s for use in aquaculture and fisheries management. These three species have …

In-situ tests of sound-bubble-strobe light barrier technologies to prevent the range expansions of Asian carp
… nobilis) and silver (H. molitrix) carp (collectively, Asian carp) have invaded the Mississippi River Basin and have successfully established populations in the Illinois River. Correlative studies have suggested that Asian carp in the Illinois River have negatively influenced native …

Spatial and temporal influences on the physiological condition of invasive silver carp
Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) (hereafter, Asian carp) are invasive species that have the potential to negatively influence non-native freshwater systems. Following their introduction to the United States in the early 1970s, Asian carp have become established in …

Economic Models of Recreational and Commercial Fishing and Their Impact on the Great Lakes Ecosystem
… Rivers. A potential control strategy for Asian carp, an invasive species, is to pay commercial fishermen a subsidy to harvest Asian carp. We estimate a model of the supply of fish and use it to determine whether a higher price for Asian carp will generate greater harvest and whether …

Impact of hypercarbia on juvenile fish physiology, behavior, performance, and acclimation potential
Asian carp are non-native invasive fishes that have quickly become the most abundant fishes in many portions of the Midwestern United States. While Asian carp are currently contained within the Mississippi River basin by a pair of electrified barriers, these fish have the potential to negatively …

Data driven modeling and simulation about carp aggregation
Asian carp is notorious as one of the most severe aquatic invasive species (AIS) threats to the waters of the Mississippi River Region. The devastating effect of Asian carp calls for desperate measures to decrease the spread of Asian carp and prevent possible invasion into the Great Lake. This work …

Shocking results: assessing the injury rates of fishes from pulsed-DC electrofishing
… gizzard shad Dorosoma cepedianum, common carp Cyprinus carpio and silver carp Hypophthalmichthys molitrix captured in the Mississippi and Illinois rivers from June 15th to October 31st, 2013 for evidence of spinal injuries from PDC boat electrofishing. Fishes were collected by …

Role of sediment oxygen demand on the oxygen balance in the North Shore Channel of Chicago
… the lake from an aquatic nuisance species, the Asian carp. The channel also has Combined Sewer Overflows (CSO) that release pollution from the city during larger storm events. By understanding the role of SOD in the North Shore Channel, engineers may be able to make decisions about intermittent …

Development of a non-invasive electrophysiological system for measuring the auditory capability of marine animals
… River to prevent the migration of non-indigenous Asian carp into Lake Michigan, and in the impact assessment of anthropogenic underwater sounds on the hearing of cetaceans and other marine animals. The ensuing Auditory Brainstem Response (ABR) electrophysiological recording technique developed at …

Fish Assemblage Structure, Trophic Ecology, and Potential Effects of Invading Asian Carps in Three Missouri River Tributaries, South Dakota
… of these systems. Two invasive species, Bighead Carp and Silver Carp (Asian carps), are spreading in the Mississippi River Basin and more recently into the Missouri River basin and tributaries. Asian carps exhibit fast population growth, are highly fecund, are plankton consumers and are known to …

Transforming an Exotic Species: Nineteenth-Century Narratives About Introduction of Carp in America
… of nineteenth-century rhetoric about common carp (Cyprinus carpio) in America, with a particular focus on Illinois. Carp, known today as one of America's most infamous exotic species, was among dozens of fishes stocked in new waters within the United States during 1870-1900, as part of a …

Bighead Carp effects on the growth, abundance, and survival of larval Bluegill
Bighead Carp (Hypophthalmichthys nobilis) are an invasive planktivore, native to Asia, that have established successful populations in the Mississippi and Illinois River systems after their unintentional introduction in the 1980’s. Their ability to efficiently consume zooplankton, has generated …
