The first outbreaks of a disease connected with high mortality of common carp and koi carp caused by koi herpesvirus (KHV) were reported in 1998 in Israel and in the United States. Since then, several cases have been confirmed all over the world. At present, this viral disease is considered to be one of the most risky factors affecting populations of common carp and koi carp. Affected fish beco...

Aeromonas infections are the most common bacterial disease of cultured fish in China. In this study, a gram-negative bacillus was isolated from the liver of diseased koi carp (Cyprinus carpio koi), and named strain KC-2. The results of morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and gyrB sequences indicated that the isolated strain KC-2 was highly...

Cyprinid herpesvirus 3 (CyHV-3), a member of the family Alloherpesviridae is the causative agent of a lethal, highly contagious and notifiable disease in common and koi carp. The economic importance of common and koi carp industries together with the rapid spread of CyHV-3 worldwide, explain why this virus became soon after its isolation in the 1990s a subject of applied research. In addition t...

The crucian carp (Carassius carassius L.) exhibits the unique ability among vertebrates to maintain cardiac performance at normoxic levels during prolonged anoxia exposure. This thesis investigates the hypothesis that this phenomenon is possible because the heart likely never experiences an extracellular pH below 7.4 due to the fish’s exclusive trait of converting lactate and H ions to ethanol....

Aeromonas hydrophila is an important opportunistic pathogen that infects a variety of aquatic and terrestrial animals, including humans. We report here the draft genome sequence of A. hydrophila Ae34, a multidrug-resistant isolate from the kidney of a moribund koi carp (Ciprinus carpio koi) with signs of hemorrhagic septicemia.

Carp interstitial nephritis and gill necrosis virus (CNGV) is an unclassified large DNA virus that morphologically resembles members of the Herpesviridae but contains a large (ca. approximately 280-kbp) linear double-stranded DNA. This virus has also been named koi herpesvirus, koi herpes-like virus, and cyprinid herpesvirus 3. CNGV is the cause of a lethal disease that afflicts common carp and...

We describe a game for second-generation (2G) cell phones with small color screens, e.g., Mitsubishi Electric’s J-D05 J-Phone. The game is a simulation that is based on the popular Japanese pastime of breeding koi (ornamental carp). It differs from other breeding-based games by attempting to emulate an existing real-world hobby: our digi-koi look like real koi and our simulated genetics exhibit...

Cyprinid herpesvirus 3 (CyHV-3), also called koi herpesvirus (KHV), is the aetiological agent of a fatal disease in carp and koi (Cyprinus carpio L.), referred to as koi herpesvirus disease. The virus contains at least 40 structural proteins, of which few have been characterised with respect to their immunogenicity. Indirect immunofluorescence assays (IFAs) using two epitope-specific monoclonal...
