This paper deals with the haematology and hemanalysis on the septicemia in Carassius auratus of pengze (♀) × Cyprinus acutidorsalis (♂) artificially injected with Aeromonas caviae strain CSS 4 2. Compared with the control fish, the haemoglobin values significantly decreased and quantity of leucocytes greatly increased in infected fish ( P ≤0.05). The percentage of neutrophil was obviously higher and that of lymphocyte, but obviously lower than that in control fish ( P ≤ 0.001 ). Total bilirubin in plasma was lower and uric acid was higher in the infected fish than that in control fish ( P ≤ 0.05 ). Creatine kinase (CK)was significantly lower than that in control fish( P ≤0.01). The results indicated that the functions of haematopoietic organs, heart and kidney broke down. Tab 2, Ref 10
