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 …

Growth and Nutrition of Carp in Heated Effluents
… growth responses and food utilization of mirror carp were investigated under varied dietary and environmental conditions. Studies showed that growth rate was least at 35°C intermediate at 20°C and greatest at 25 & 30°C. Food conversion ratio increased with increasing level of feeding at each …

The Utilization of Dietary Carbohydrates by Trout and Carp
… activities in Rainbow trout and Mirror carp when respectively fed 0-30% and 0-45% of cassava, rice, corn, potato or dextrin in isonitrogenous diets were investigated. In trout, optimum growth and food utilization was at 20% dietary cassava or rice. Weight gain was positively correlated …

The Husbandry and Nutrition of Carp Larvae and Fry
… live food during first stage rearing of mirror carp (Cyprinus carpio) larvae, diet presentation and related husbandry techniques, as well as selected nutritional requirements of carp juveniles, were studied. Carp larvae held at a temperature of 24°C in continuous light showed optimal growth and …

Control of Common Carp in the Heron Lake Watershed, Minnesota
Common carp Cyprinus carpio were radiotracked during the winter of two years in North (83 7 hectares) and South (13 60 hectares) Heron Lakes, Minnesota to monitor survival and behavior in these shallow (maximum depth 1. 5 m), turbid lakes. Winterkill conditions killed four of six radiotagged common …

Effects of Common Carp and Black Bullheads on Sago Pondweed
<p>Overabundant populations of common carp (Cyprinus carpio) and black bullheads (Ictalurus melas) may have a detrimental effect on submerged aquatic plant production and thus waterfowl habitat. The relative impact of small common carp (0.9 kg), large common carp (1.5 kg), and black bullheads ( 0.7 …

Biology and ecology of bigheaded carp in an invaded ecosystem
… to successful invasions, using bigheaded carps (<em>Hypophthalmichthys</em> spp., silver and bighead carp and their hybrids) in the Wabash River, Indiana (USA), as a case study. Trends in population characteristics appeared to vary with invasion stage. Female-skewed sex ratios, changing …

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. …

Population Dynamics of Common Carp in Eastern South Dakota Glacial Lakes
… as an accurate aging technique for common carp Cyprinus carpio. However, common carp otoliths can be difficult to age and require a time-expensive process that involves sacrifice of fish. Therefore, I analyzed aging precision among four alternative structures compared to otoliths for 139 …

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 …

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 …

Behavior and population dynamics of grass carp incrementally stocked for biological control
Grass carp Ctenopharyngodon idella have been stocked throughout the world due to their utility as a biological control. In the United States, the species has been used to successfully control invasive, aquatic weeds such as hydrilla Hydrilla verticillata. Despite the large body of research …

The effects of common carp on zooplankton communities using morphological and molecular techniques
… this is intensified with the presence of common carp (Cyprinus carpio). The overall aim of this thesis was to capture the environmental and biological changes of a natural pond environment when carp were introduced at a high density, and to develop and test a DNA based approach of assessing …

MORPHOLOGY, MATERIAL AND VIBRATORY PROPERTIES OF THE SWIMBLADDER IN THE CARP, CYPRINUS CARPIO
The carp Cyprinus carpio has a two-chambered swimbladder and excellent hearing. I explored the hypothesis that the anterior chamber, which connects to Weberian ossicles, is adapted for hearing by testing both chambers for material properties. I also determined displacement and auditory responses to …

Invasive SIlver Carp (Hypophthalmichthys molitrix) Protein Hydrolysates- A Potential Source of Natural Antioxidant
<p>Invasive silver carp (Hypophthalmichthys molitrix), continue to spread over the Mississippi River causing a great concern for the river ecosystem due to their impact on native fish species. To minimize the negative effects of silver carp, many strategies were implemented including using it for …

The Effect of Anabolic-Androgenic Steroids on the Growth and Metabolism of Carp
Groups of juvenile common carp (Cyprinus carpio) were fed diets supplemented with eight anabolic-androgenic steroids and one anti-androgenic steroid at doses of 1.0, 2.5, 5.0 and 10 mg/kg dry diet for sixty or ninety days, and their effect on growth, food conversion and body composition observed. …
