Abstract: The present study is developed for determination of an appropriate weight of releasing Abramis Brama Orientalis fry of Caspian Sea toward increase in fisheries returning coefficient. Consequently, blood factors including Sodium Ion, Potassium Ion, chlorine Ion, Cortisol Hormone, Blood Protein, growth and permanence indexes of Abramis Brama Orientalis fry are considered in four different weight groups of 320, 470, 730 and 990 mg. in fresh and brackish waters. The test extended up to 14 days in brackish water (9 g/l salinity). The result show that the blood factors in all weight groups have high significant differences in fresh waters (p<0.01). In the end of the test, the Sodium viscosity of Abramis Brama Orientalis fry blood has no any significant differences in none of the weight groups (p>0.05); whereas, other blood factors have significant differences to each other (p<0.01). No any differences were observed within growth index of the weight groups (p<0.05). Also, holding higher percentage of permanence at the end of the test and considering the quantity of mortalities, the weight group of 990 mg. is selected as the best weight option of Abramis Brama Orientalis due to its physiological readiness for releasing to the Caspian Sea.
