| [polymorphism of microsatellite markers in breeds of common carp (cyprinus carpio l.) of russian breeding]. | using five microsatellite loci, genotyping and genetic diversity estimates were obtained for nine samples representing seven common carp breeds most widespread in russia. for comparison, the samples of amur wild common carp (cyprinus carpio haematopterus) and a sample of european hungarian common carp were used. in the samples examined (n = 148) a total of 78 alleles were revealed. the highest mean allele number per locus (4.3) was identified in amur wild common carp, while the lowest number was ... | 2010 | 20583601 |
| [epizootological characterization of trematodiasis foci in the ecosystem of the amur river in the khabarovsk territory]. | investigations were conducted in late june to early june 2013. the population density of mollusks of the genus juga in the shoreline and littoral covered by meadow waters was 10 to 30 specimens/m2; there were solitary specimens of the genus parafossarulus. fourteen out of 39 fish species were invaded by metacercariae of clonorchis. manchurian spiny loaches (leptobotia) and light's bitterling (rhodeus lighti) are first registered to be hosts of clonorchis. the metacercariae of metagonimus yokogaw ... | 2015 | 26152032 |
| assessment of the state of the gibel carp carassius auratus gibelio in the amur river basin: heavy-metal and arsenic concentrations and histopathology of internal organs. | this study describes the concentrations of heavy metals and arsenic (as) and the basic histopathological changes in the internal organs of gibel carp carassius auratus gibelio from five sites of the amur river basin. gibel carp from sindinskaya passage had the highest liver concentrations of zinc (zn) (31.95 ± 13.443), copper (cu) (12.52 ± 5.746), manganese (9.22 ± 8.121), and cadmium (0.37 ± 0.660 mg/kg wet weight [ww]) compared with fish captured from the bol'shoi ussuriiskii island area and k ... | 2012 | 22012303 |
| [collation of data on the ploidy levels and mitochondrial dna phylogenetic lineages in the silver crucian carp carassius auratus gibelio from far eastern and central asian populations]. | the distribution of the diploid and triploid forms and the correspondence between ploidy and mitochondrial dna (mtdna) phylogenetic lineages of the silver crucian carp have been studied in far eastern water bodies and the syr darya river. both diploid and triploid forms have been found in large river systems (the amur, suifun, tumangan, and syr darya river basins). only the diploid form has been detected in lakes of bol'shoi pelis island (peter the great bay of the sea of japan), sakhalin island ... | 2008 | 18767549 |
| [polymorphism of the cytochrome oxidase b gene (cyt b) in russian populations of common carp and wild common carp (cyprinus carpio l.)]. | polymorphism of the mitochondrial cyt b gene was examined in 35 individuals of common carp and wild common carp (cyprinus carpio l.). the fish examined represented two natural populations from khabarovsk krai (ac and am), volga wild common carp, don wild common carp, and two common carp breeds, ropsha (strains bb and mm) common carp and hungarian common carp. the highest level of nucleotide (pi) and haplotype (h) diversity was detected in two strains of ropsha common carp (mm, pi = 0.67%, h = 0. ... | 2012 | 22567860 |
| [biology of khawia japonensis (caryophyllidea, cestoda), a parasite of the amur carp]. | the development of the cestode khawia japonensis (yamaguti, 1934) has been studied experimentally. at 18 to 26 c, in 12-14 days oncospheres develop in eggs, whose infective properties manifest themselves in 30-31 days. in the caudal segments of limnodrilus udekemianus they penetrate the body cavity through the intestinal wall and migrate to the anterior margin as they mature. in 55 to 60 days (at the same temperature) mature proceroids become localized in 9-12 segments. the development of embryo ... | 2007 | 733320 |
