Twin-tail goldfish strains are examples of drastic morphological alterations that emerged through domestication. Although this mutation is known to be caused by deficiency of one of two duplicated chordin genes, it is unknown why equivalent mutations have not been observed in other domesticated fish species. Here, we compared the chordin gene morphant phenotypes of single-tail goldfish and comm...

Cyprinid herpesvirus 3 (CyHV-3) causes a lethal disease in common and koi carp (Cyprinus carpio). The present study investigated the ability of CyHV-3 to infect common carp during the early stages of its development (from embryos to fingerlings) after inoculation by immersion in water containing the virus. Fish were inoculated at different times after hatching with a pathogenic recombinant CyHV...

Little information on the effects of a high α-linolenic acid (C18:3n-3) diet fatty composition and lipid-producing gene expression in hepatopancreas from Yellow River carp (Cyprinus carpio). In study, 60 common juveniles were fed for 50 days, supplemented with linseed oil (LO), control without addition to evaluate effect lipid peroxisome proliferator-activated receptors (PPAR-α), delta-6 desatu...

Fish, like mammals, can be affected by neoplastic proliferations. As yet, there are only a very small number of studies reporting on the occurrence of tumours in koi carp Cyprinus carpio koi and only sporadic reports on the nature of the tumours or on risk factors associated with their development. Between 2008 and 2012, koi with abdominal swelling were examined pathologically: neoplastic lesio...

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...

apolipoprotein a-i is the most abundant protein in cyprinus carpio plasma that plays an important role in lipid transport and protection of the skin by means of its antimicrobial activity. a 527 bp cdna fragment encoding c terminus part of apoa-i from the skin mucosa of common carp was isolated using rt-pcr. after genbank database searching, a partial sequence containing a coding sequence (cds)...
