Emergence of carp edema virus in cultured ornamental koi carp, Cyprinus carpio koi, in India

Immune Response to Koi Herpesvirus (KHV) of Koi and Koi × Red Common Carp (Cyprinus carpio)

Koi herpesvirus (KHV), also known as Cyprinid herpes virus 3 (Cyprinid 3) is lethal disease in common carp and koi (Cyprinus carpio). Two different groups (KK and RK) were infected KHV by intraperitoneal injection. Fish for gene expression analysis were sampled at 0 h, 12 h, 24 h, 48 h and 72 h post infection (p.i). The results showed that two immune related gene, Interferons (INFs) ɑβ and Inte...

Effect of ploidy on scale-cover pattern in linear ornamental (koi) common carp Cyprinus carpio.

The effect of ploidy on scale-cover pattern in linear ornamental (koi) common carp Cyprinus carpio was investigated. To obtain diploid and triploid linear fish, eggs taken from a leather C. carpio female (genotype ssNn) and sperm taken from a scaled C. carpio male (genotype SSnn) were used for the production of control (no shock) and heat-shocked progeny. In heat-shocked progeny, the 2 min heat...

Melanocortin receptor 1 and black pigmentation in the Japanese ornamental carp (Cyprinus carpio var. Koi)

Colors and their patterns are fascinating phenotypes with great importance for fitness under natural conditions. For this reason and because pigmentation is associated with diseases, much research was devoted to study the genetics of pigmentation in animals. Considerable contribution to our understanding of color phenotypes was made by studies in domesticated animals that exhibit dazzling varia...

Risk factors for development of internal neoplasms in koi carp Cyprinus carpio koi.

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...
