This study was conducted to find out the effect of bile salts in fish ration on indexes of growth, survival, carcass composition and some of the hematological and biological indexes of blood serum for this purpose 300 juvenile common carp (Cyprinus carpio) with an average weight of 3 ± 0.5 grams were studied for 12 weeks. Cow bile salts were added to the ration of fry fish at 5 different levels of 0, 0.25, 0.50, 0.75, and 1 percent during the experiment, two daily feedings were given at the ratio of 3 to 5% of the living mass. At the end of the experiment, data analysis revealed no significant differences in indexes of growth and survival, protein, ash, and carcass moisture between different treatment groups (P>0.05). Treatment group 4 with 1% bile salt had the least amount of fat, 32.52 ± 0.629%, and statistically, it was significantly different from other groups (P<0.05). Also, group 2 with 0.5% bile salts showed the highest and control group with 0% bile salts showed the lowest level of blood cholesterol and triglyceride, and therefore were significantly different from other groups (P< 0.05). Also the total amount of protein, white blood cells, red blood cells, hemoglobin, hematocrit and MCH, MCHC, MCV were significantly different between treatment groups and the control group (P< 0.05).
