The exotic grass carp ( Ctenopharyngodon idella ) has been used for almost a half a century in the United States as a biological agent to control and manage aquatic plants. This long-lived generalist herbivore consumes large amounts of vegetation and can considerably alter habitat and impact aquatic communities. We conducted a literature review to determine whether previous studies adequately a...

The involvement of circulatory glucose in the energy provision of skeletal muscle and heart of swimming carp was examined. Plasma glucose concentration varied from 3 to 17 mM among individual carp, and estimates of glucose turnover rate (RT) were positively correlated with plasma glucose level in resting fish (range 1.6-6.3 mumol.min-1.kg-1) and in swimming fish (range 4.2-10.7 mumol.min-1.kg-1...

Although carp is still widely sold and used in its fresh form, a range of value additions may also be observed. It is essential to know the development and management of a carp farm production costs and their evolution. In Iran, warm-water fish farming is based on common, silver, grass, and bighead carps. The carp is easy to rise in hatcheries in very large numbers at little cost, and is distri...

Some issues in risk assessment reports on grass carp and silver carp.

Literature reviews of all references concerning the parasitic fauna of fishes in fish farms of Babylon province, middle of Iraq, showed that a total of 92 valid parasite species are so far known from the common carp (Cyprinus carpio), the grass carp (Ctenopharyngodon idella), and the silver carp (Hypophthalmichthys molitrix) as well as from three freshwater fish species (Carassius auratus, Liza...

Although the movement of invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) in the Upper Mississippi River system is dependent on their ability to swim through its numerous lockanddams, the swimming performance of adults of these species is at present unknown. Using a large (2,935L) mobile swim tunnel, the swimming performance of adult bighead and adult silver carp...

AIMS It has been reported that cardiac ankyrin repeat protein is associated with heart development and diseases. This study is aimed to investigate the role of CARP in heart hypertrophy in vivo. METHODS AND RESULTS We generated a cardiac-specific CARP-overexpressing transgenic mouse. Although such animals did not display any overt physiological abnormality, they developed less cardiac hypertr...

In many species of aquaculture importance, all-female and sterile populations possess superior productivity due to faster growth and a relatively homogenous size of individuals. However, the production of all-female and sterile fish in a large scale for aquaculture is a challenge in practice, because treatments necessary for gynogenesis induction usually cause massive embryonic and larval morta...

In lakes of the Upper Mississippi River Basin (UMRB), invasive common carp (Cyprinus carpio) employ a reproductive strategy in which adults migrate out of lakes to spawn in seasonally unstable marshes that have few egg and larval predators. The rates with which the juveniles outmigrate from marshes into adjacent lakes have critical management implications but have not been quantified using dire...
