BACKGROUND Although the common, silver, and bighead carps are native and sparsely distributed in Eurasia, these fish have become abundant and invasive in North America. An understanding of the biology of these species may provide insights into sustainable control methods. The animal-associated microbiome plays an important role in host health. Characterization of the carp microbiome and the fac...

Composite culture of edible fishes (common carp, Cryprinus carpio; silver carp, Hypopthalmithys molitrix, grass carp, Ctenopharyngodon idella; catla, Catla catla; rohu, Labeo rohita; and mrigal, Cirrhinus mrigala) in rice fields in the Cauvery delta of Tamil Nadu, southern India, resulted in 81.0% reduction in the immature mosquito population of anophelines and 83.5% of culicines. Analysis of f...

Characterizing biological factors associated with species-specific accumulation of contaminants is one of the major focuses in ecotoxicology and environmental chemistry studies. In this study, polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and non- and mono-ortho-substituted polychlorinated biphenyl (PCB) congeners were analyzed in various fish species from the Tittabawassee ...

Understanding the causal mechanisms that determine recruitment success is critical to the effective conservation of wild fish populations. Although recruitment strength is likely determined during early life when mortality is greatest, few studies have documented age-specific mortality rates for fish during this period. We investigated age-specific mortality of individual cohorts of two species...

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...

—The silver carp Hypophthalmichthys molitrix has spread throughout the Mississippi River drainage. During 2003, we determined its population status and potential impact in the middle Mississippi River (MMR), the conduit between the lower Mississippi River and the upper Mississippi, Missouri, and Illinois rivers. We quantified growth, age structure, fecundity, and diets of silver carp sampled wi...

the aim of this study was to determine the concentration of copper and hazard quotient (hq) in muscle of the carp aquaculture fishes (common carp) (cyprinus carpio), grass carp (ctenopharyngodon idella), big head carp (aristichthys nobilis) and silver carp (hypophthalmichthys molitrix)] in khuzestan province. 108 pieces farmed fish sampled was prepared from the azadegan warm water fish culture ...

the karyotype of zagros tooth-carp, aphanius vladykovi (coad) has been investigated byexamining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. the diploidchromosome number of this species was 2n=48. the karyotype consisted of 8 submetacentric and 40subtelocentric chromosomes (8sm+40 st). the arm number (nf) was 28. sex chromosomes werecytologically indistinguishab...

The Sanandaj Gheshlagh Reservoir (SGR) is a mercury polluted lake that is located in the West of Iran. Common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) are the most abundant fishes in the SGR. A total of 48 common and silver carps (24 each) were captured randomly, using 50×6 m gill net (mesh size: 5×5 cm) during July to December 2009. Each month, the levels of accumul...

The silver carp (Hypophthalmichthys molitrix) is among the most intensively pond-cultured fish species and is used in the wild to counteract water bloom in China. However, little genomic information is available for this species, especially regarding its ability to grow rapidly in water, even water contaminated with high concentrations of poisonous microcystin. In this study, we performed de no...
