This current study aimed to study the effect of adding blue-green algae (Spirulina), symbiotic (poultry star®me) at a ratio of 1 to 2% and colistin antibiotic to the control diet of common carp fish reared in glass aquariums for 56 days terms of three replicates for each treatment. The growth results showed that the fish fed on the third diet was significantly superior to the fish fed on the other experimental diets in the rate of total and daily weight gain, feed conversion ratio, feeding efficiency ratio and protein efficiency ratio criteria over all other experimental diets except for the second diet, 1% spirulina. The fish fed on the second diet significantly outperformed in the precipitated protein criterion and the protein productive value of all the experimental diets under study. The value of crude protein in the edible portion increased significantly when fish were fed on spirulina, symbiotic and antibiotic diets, compared to the control diet, while the percentage of fats in the fish fed on diets containing the food additives under test decreased significantly compared to the control diet. No significant differences were recorded in the percentage of ash. It is evident from what was mentioned above that the best results of the studied criteria were when adding spirulina at had positive effects on growth criteria and food utilization.

This study was carried out to study the effect of adding different levels of the microalgae Spirulina spp. in fish laboratory of Animal Sciences Department, College of Agricultural Sciences of Sulaimani University, Sulaimani, Iraq. A total of 72 common carp fingerling weight 45±2 gm used to detect the effect of three different levels of the algae Spirulina spp. The control treatment T1 with 0%., T2 with 3 gm /kg diet and T3 with 5 gm Spirulina /kg diet. Each treatment in three replicates in which six fingerlings common carp were stocked in each aquarium. Results indicated no significant differences at PSpirulina) in T3 was higher significantly at PSpirulina was higher significantly at PSpirulina to common carp diets in different levels leads to significant differences in differential WBC counts, T3 with 5 gm Spirulina /kg diet was higher in WBC counts. Lymphocytes were higher in each of control and T3. Monocytes were higher in control, granulocytes in T2 with 3 gm Spirulina /kg diet. Adding of Spirulina affected significantly in cholesterol as compared to the control. Triglyceride was higher in control and T2. T3 with 5 gm Spirulina /kg diet leads to higher and lower significantly in HDL and LDL respectively. T1 and T3 were higher significantly in spleenosomatic index. Inclusion of S. platensis in fish diet as a feed additive or as a partial replacer of the expensive fishmeal imposes significant promotions in fish growth, coloration, reproduction and flesh quality.

This study was conducted to evaluate the effect of replacing fishmeal with Spirulina spp. in four different levels 0%, 5%,
10%, 15% and 20%, as T1, T2, T3, T4and T5 respectively on Carcass means weight (CMW) with head and without peripheral
organs and CMW without head and peripheral organs, where the third and fifth treatment give the higher value in CMW with
head and without peripheral organs, and the fifth treatment obtain significant differences in CMW without head and peripheral
organs as compared to other treatment. When regarding the chemical composition in which the higher significant difference
found in the T3 and T5 in crude protein, the T5 significantly differ in crude fat as compared with other treatments.
