| mitochondrial genome sequencing and development of genetic markers for the detection of dna of invasive bighead and silver carp (hypophthalmichthys nobilis and h. molitrix) in environmental water samples from the united states. | invasive asian bighead and silver carp (hypophthalmichthys nobilis and h. molitrix) pose a substantial threat to north american aquatic ecosystems. recently, environmental dna (edna), genetic material shed by organisms into their environment that can be detected by non-invasive sampling strategies and genetic assays, has gained recognition as a tool for tracking the invasion front of these species toward the great lakes. the goal of this study was to develop new species-specific conventional pcr ... | 2015 | 25706532 |
| interspecific and spatial comparisons of perfluorinated compounds in bighead and silver carp in the illinois river, illinois, usa. | we examined perfluoroalkyl compounds (pfc) in bighead (bhcp; hypophthalmichthys nobilis) and silver (svcp; h. molitrix) carp from the illinois river, illinois, usa. summed pfc concentrations in whole fish did not differ by species or river reach. perfluorooctanesulfonate (pfos) concentrations were much greater in whole fish (16.4 ng/g) than in fillets (3.4 ng/g). pfos concentrations represented 35%-51% of total measured pfc concentrations in whole fish, and in fillets were weakly associated with ... | 2015 | 26358646 |
| contaminant concentrations in asian carps, invasive species in the mississippi and illinois rivers. | populations of invasive fishes quickly reach extremely high biomass. before control methods can be applied, however, an understanding of the contaminant loads of these invaders carry is needed. we investigated differences in concentrations of selected elements in two invasive carp species as a function of sampling site, fish species, length and trophic differences using stable isotopes (delta (15)n, delta (13)c). fish were collected from three different sites, the illinois river near havana, ill ... | 2009 | 18850294 |
| elements of concern in fillets of bighead and silver carp from the illinois river, illinois. | efforts to control invasive bighead (hypophthalmichthys nobilis) and silver carp (h. molitrix) may include harvest for human consumption. we measured concentrations of arsenic (as), mercury (hg), and selenium (se) in fillets from silver and bighead carp collected from the lower illinois river, illinois, usa, to determine whether concentrations were of health concern and differed by species, size, and location. concentrations of total as were below detection limits in most bighead (92%) and silve ... | 2014 | 24300421 |
| restriction site-associated dna sequencing generates high-quality single nucleotide polymorphisms for assessing hybridization between bighead and silver carp in the united states and china. | bighead carp (hypophthalmichthys nobilis) and silver carp (h. molitrix) are invasive species and listed as us federally injurious species under the lacy act. they have established populations in much of the mississippi river basin (mrb; mississippi, illinois, and missouri rivers) and are capable of producing fertile hybrids and complex introgression. characterizing the composition of this admixture requires a large set of high-quality, evolutionarily conserved, diagnostic genetic markers to aid ... | 2014 | 23957862 |
| spatial and interspecific patterns in persistent contaminant loads in bighead and silver carp from the illinois river. | we measured concentrations of selected organohalogens, fluorinated compounds and mercury in whole, ground silver (hypophthalmichthys molitrix) and bighead (h. nobilis) carp from the illinois river, illinois, in 2010 and 2011 to characterize spatial and interspecific patterns of contaminant burdens. silver carp, which had greater lipid content, tended to have greater concentrations of lipophilic compounds. concentrations of organohalogens were generally greater in carp from the upper reaches of t ... | 2013 | 23887862 |
