The common carp (Cyprinus carpio), has great commercial importance because it is the most common fish that is widely consumed worldwide. Knowledge of the blood biochemical parameters of this animal would be helpful for evaluations of their health. In this regard, the serum biochemical values were measured in 60 common carp (of either sex). Serum values of glucose (GLC; 0.42 ± 0.015 g/L), cholesterol (CHL; 1.7± 0.07g/L), total protein (TOP; 33.2±0.6 g/L), albumin (ALB; 15.1±1.5g/L), creatinine (CRT; 0.035±0.002 g/L),urea 0.04±0.002g/L, lactate dehydrogenase (LDH; 115.2±8.22 U/L), aspartate transaminase (AST;48.2±3.6 U/L), alanine transaminase (ALT;21.2±3.6 U/L), triglyceride (TRG; 1.01± 0.1g/L , alkaline phosphatase (ALP;37.2± 5.5 IU/L) and uric acid (UA;0.01± 0.003 g/L)were determined respectively.
