The present investigation was carried out to compare the haematological and biochemical parameters in healthy and Monogenean infected Cyprinus carpio. The haematological analysis showed significant reduction (P<0.01) in RBC, haemoglobin, haematocrit (PCV) and lymphocyte in monogenean infected fishes, whereas total leucocyte count (TLC), neutrophils, eosinophils and monocytes significantly incre...

The Common carp, Cyprinus carpio was exposed to sublethal concentrations of chromium for various exposure periods (8, 16, 24 and 32days). Serum glucose, total protein, total cholesterol, serum GOT and GPT were measured both in control and experimental fish. During various exposure periods (8, 16, 24 and 32 days), the levels of serum glucose, total cholesterol, GOT and GPT levelss were (P<0.05) ...

Androgenesis involves the development of an organism with only paternal chromosomes. The induction of androgenesis using diploid sperm, highly effective UV-irradiation of egg, dispermy using heterologous eggs, the possibility of producing supermales for all male production and the recovery of cryopreserved sperm are recent technological developments in androgenesis in fish. However, few researc...

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...
