Studying of haematological parameters of young fish of the Lena sturgeon spent in August, 2012 on the basis of OS "ОРХ "Selets" in the Brest area. Researches of blood of the fishes growing up in artificial conditions, allow establishing a degree of deviations from norm and character haemotological adaptations. Studying of blood parameters enables to determine a degree of fishes adaptation in conditions of a concrete reservoir.On the basis of the research it was determined that the highest rates of red blood and lymphoid nature of the blood formula indicate good physiological condition and high adaptive capacity of the Lena sturgeon fingerlings grown in climatic conditions of Belarus. Stocking density of 6,0 thousand ind./m2 during curing, 2,0 thousand ind./m2 when switching to artificial feeds and 1,0 thousand ind./m2 when rearing to weight of 2-3 g do not have a negative impact on the development of the Lena sturgeon fingerlings and can be offered as a standard for rearing juveniles to 30 grams of weight at fish farms of the Republic of Belarus
