Abstract
    The aim of this work presents the results of an experiment that was conducted over a period of 30 days (24.05.2013-22.06.2013), where we used specimens of A. stellatus (Starry) aged 13 months and 22 days.
    We have used two tubs: in the first tub were 40 species with a total biomass of 3916 g and in the second tub were 39 species with a total biomass of 4012 g.
    The fish from the two tubs were fed with fodder "Alterna Storione", the difference between the two tubs is: in the first tub we have to incorporated the vitamins C and E, and in the second tub we used the feed as it self.
    At the end of the experiment, in the first tub (C + E) we obtained a weight gain of 1199 g, and in the second tub we obtained weight gain of 1153 g.
    In the hematological profile we have obtained the following results: in the first tub (C + E) the hemoglobin 8.58±0.94 g/dl the glucose 69.46±7.12 ml glucose / 100ml blood, the proteins 3.83±0.28 g proteins/100 ml serum, hematocrit 26.46±3.67, the leukocyte 1.65±0.070 and the erythrocytes ranged from 0,77 - 10⁶ cells / µl blood and 0,875- 10⁶ cells / µl blood; in the second bath(control): the hemoglobin 9.23±1.66 g/dl, the glucose 62.06±4.75 ml glucose/100ml blood, the proteins 3.7±0.33 g proteins/100 ml serum, the hematocrit 30.48±5.71, the leukocyte 1.69±0.085 and the erythrocytes ranged between 0,67 - 10⁶ cells / µl blood and 0.745 - 10⁶ cells / µl blood.
    In summary, we obtained different values referring to the gain, the increase of the specimens used in the both baths and their hematological profile was affected by the feed method used differently in the two baths.
