EFFECT OF USING DIFFERENT LEVELS OF CANOLA OIL ON THE HEMATOLOGICAL AND BIOCHEMICAL CHARACTERISTICS OF COMMON CARP CYPRINUS CARPIO L.

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