CIRKOVIC, M., N. MILOSEVIC, M. MARKOVIC and A. POTKONJAK, 2010. Brain myxoboliasis of common carp. Bulg. J. Agric. Sci., 16: 263-265 The common carp (Cyprinus carpio) originating from Serbian fish ponds was examined for presence of Myxobolus encephalicus. The spores of M. encephalicus were present in blood vessels and meningeal layers. Its presence has been noted in 32-days old carp fingerlings...

The oxygen consumption rates of two cyprinid fishes, carp (Cyprinus carpio L.) and roach (Rutilus rutilus (L.)), were analysed for a wide range of body mass and swimming speed by computerized intermittent-flow respirometry. Bioenergetic models were derived, based on fish mass (M) and swimming speed (U), to predict the minimal speed and mass-specific active metabolic rate (AMR) in these fishes (...

Koi herpesvirus disease (KHVD) is a highly contagious viral illness causing significant morbidity and mortality in common carp (Cyprinus carpio). KHVD has been confirmed in almost all countries around the world except Australia. KHV has been previously detected in the Czech Republic based on PCR screening but with no clinical signs of KHVD. An outbreak of KHVD with clinical signs, and severe mo...

OBJECTIVE The aim of this study was identification of the parasites of the common carp from Tahtalı Dam Lake. METHODS The fish were transported live to the laboratory. They were investigated for ectoparasites and endoparasites. The parasite specimens were fixed and identified. RESULTS During the study, 47 common carp were caught monthly and 3 species of metazoan parasites were found: Dactyl...

BACKGROUND Single nucleotide polymorphisms (SNPs) have been used as genetic marker for genome-wide association studies in many species. Gene-associated SNPs could offer sufficient coverage in trait related research and further more could themselves be causative SNPs for traits. Common carp (Cyprinus carpio) is one of the most important aquaculture species in the world accounting for nearly 14% ...

cDNA clones encoding the myosin regulatory light chain (RLC) were isolated from a cDNA library prepared from fast skeletal muscle of the carp Cyprinus carpio L. Two types of cDNA clone encoding carp RLC were found with identical deduced amino acid sequences. The two mRNAs differed in the number of polyadenylation signals prior to the poly(A) tail in the 3' non-coding region. The two mRNA specie...

Behavioral responses of silver carp (Hypopthalmichthys molitrix), bighead carp (H. nobilis), and common carp (Cyprinus carpio) to a complex, broadband sound were tested in the absence of visual cues to determine whether these species are negatively phonotaxic and the roles that sound pressure and particle motion might play mediating this response. In a dark featureless square enclosure, groups ...

A species not identifiable with any of the about 23 Myxobolus species recorded from the common carp so far, was detected in the gills of one- and two-summer-old specimens of the common carp ((Cyprinus carpio L.) cultured in pond farms in Hungary. The strictly tissue-specific plasmodia of the parasite were located, surrounded by hyaline cartilage cells, in the chondrous substance of the terminal...

RASKOVIC, B., V. POLEKSIC, I. ZIVIC and M. SPASIC, 2010.Histology of carp (Cyprinus carpio L.) gills and pond water quality in semiintensive production. Bulg. J. Agric. Sci., 16: 253-262 Gills of carp from ponds of the “Vrsacki ritovi” fish farm were studied, and the results discussed with reference to the results of physical and chemical properties of pond water. Subepithelial edema and gill h...

Infections of common carp Cyprinus carpio and koi, its coloured morphotypes, with the cyprinid herpesvirus 3 (CyHV-3) can induce severe clinical signs and increased mortality in affected stocks. This may significantly challenge the economic basis of carp farming in Central Europe. To limit virus spread in carp farms, effective disinfection measures for ponds stocked with infected populations ar...
