The fish production industry has become one of the most important animal production projects, and fish industry suffer from feed costs, so this study aims to find accessible food additives that increase production or reduce costs. This was done by 126 fish of common carp (Cyprinus carpio L.) Average individual weight 42.72 g ± 2.28 g. and 254.78 g ± 2.95 g biomass weight. were randomly distributed to 21 aquaria, with seven treatments with three replicates, 6 fish per aquarium. Fish were fed 3% by weight of biomass, on a prepared diet with a protein content of 28%. It was divided into seven sections by treatments, T1 without addition, T2, T3and T4 adding sunflower oil 2, 4 and 6 g/kg, consecutively, T5, T6 and T7 adding canola oil 2, 4, and6 g/kg consecutively. The experiment period lasted 70 days, at the end of the experiment blood samples were taken from the experimental fish. The results of the blood and biochemical characteristics of common carp showed that there were no significant differences at the level (P≤0.05) in all experimental treatments.
