“…Перспективным направлением в кормопроизводстве является изготовление комбикормов с применением пробиотических препаратов на энтеросорбентах, необходимых для профилактики и лечения заболеваний рыб бактериальной и вирусной этиологии, нормализации микрофлоры кишечника путем выведения из организма патогенных и условнопатогенных микроорганизмов, токсинов и продуктов метаболизма [3]. Такие препараты позволяют смягчать стрессы, вызываемые сменой комбикормов и технологическими воздействиями на организм рыб, служат для повышения резистентности организма и напряженности иммунитета, позволяют увеличить усвояемость комбикормов [4].…”

The article considers a method to obtain environmentally friendly aquaculture products (red tilapia (Oreochromis mossambicus × Oreochromis niloticus) by adding the probiotic preparation Ecoflor to the balanced mixed feed. The probiotic component of the preparation formed by several strains of bifid and lacto bacteria gives the prepa-ration ability to improve the intestinal microflora of fish, activate the immune system, remove unfavorable microflora formed by metabolic products, heavy metals, radionuclides, toxins and metabolites, increase the rate of formation and accumulation of biomass of beneficial microflora in the digestive tract of fish. In the Aquaculture Technical Center under Astrakhan State Technical University there were grown 4 groups of red tilapia, 15 species in each group. Three experimental groups were fed with compound feed with the addition of probiotic Ecoflor by 2, 4 and 6 g/kg. The results were compared between the experimental groups, as well as with the control. It has been proved that feeding red tilapia with balanced mixed fodders with the addition of the immobilized probiotic preparation “Ecoflor” at a dose of 4 g/kg of feed helps to activate the protective functions of the body, normalize the metabolic processes, optimize digestive processes. The absolute increase in the group that received food with a probiotic at a dose of 4 g/kg of feed was 7.7 more than in the control. It significantly exceeded the increase in other experimental groups, which allows reducing feed costs to 1.1 units. The use of the developed compound feed in the cultivation of red tilapia makes it possible to obtain eco-friendly fish bio-products even if the waters used for fish breeding are polluted.

Assessment of the physiological and immunological status of fish is an urgent problem of modern aquaculture. One of the methods of such assessment is based on hematological and biochemical studies. Blood is the most sensitive and informative indicator of changes occurring in the body of fish. It reacts quickly and acutely to the effects of various adverse environmental factors and can serve as one of the early indicators of a violation of the functional state of fish. The study of the effect of a probiotic drug on the enterosorbent “Florin forte” on hematological and biochemical blood parameters, in particular, on the level of hemoglobin, total serum protein, triglycerides, cholesterol, glucose, as well as on the distribution of shaped elements of peripheral blood of Bester (Huso huso × Acipenser ruthenus) was carried out on the basis of the Innovation Center “Bioaquapark – scientific andtechnical center of aquaculture” ASTU for 30 days. As a result of the conducted studies, it was noted that the use of the sorbed form of the probiotic drug has a positive effect on the physiological and immunological condition of the farmed fish. Thus, the blood of Bester's two-year-olds grown on compound feeds with the addition of probiotic enterosorbent was characterized by an increase in hemoglobin levels to 64.9 g/l, total whey protein to 23.6 g/l, as well as a decrease in cholesterol and glucose concentrations to 2.6 and 0.55 mmol/l, respectively. In the leukocyte formula of the studied fish, shifts in the quantitative ratios of leukocytes were found, confirming the body's reaction to the introduction of a probiotic drug on enterosorbent into the diet and considered as an adaptive mechanism that increases the protective function of the blood.
