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...
متن کاملEffects of stocking density on growth performance, immune and stress responses in koi carp (Cyprinus carpio var. Koi (Linnaeus, 1758))
The aim of this study was to determine the optimal stocking density in koi carp (Cyprinus carpio var. Koi). For this reason, 2400 juvenile koi (1.28 ± 0.11 g) were stocked at five levels of density (50, 100, 150, 200 and 300 fish per m3) and reared for 11 weeks and growth performance, survival rate, and hematological parameters were evaluated. There was no significant difference between first t...

متن کاملRoutine turning maneuvers of koi carp Cyprinus carpio koi: effects of turning rate on kinematics and hydrodynamics.
Spontaneous swimming behaviors of koi carp Cyprinus carpio koi were recorded using a video tracking system. Routine single-beat turns were selected from the recorded image sequences for kinematic and hydrodynamic analysis. As with C-starts, the turns can be divided into two stages (stage 1 and stage 2), based on kinematics. Stage 1 involves a bend to one side forming a C-shaped curve in the bod...
متن کاملRisk 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...
