METHOD OF CULTIVATING HYDROBIONTS USING BIOFLOC TECHNOLOGY Russian patent published in 2024 - IPC A01K61/00 C12N1/20 C02F3/34 C12R1/38 C12R1/46 C12R1/125 C12R1/225 

FIELD: biotechnology.

SUBSTANCE: disclosed is a method of cultivating hydrobionts, which involves adding a mixture of probiotic microorganisms to a pool with water Bacillus subtilis, Lactobacillus paracasei, Streptococcus thermophilus; Pseudomonas aureofaciens, aeration and mixing of water with ascending flows of water-air mixture from the bottom of pool using 6 diffusers on the EPDM membrane and a piston compressor; upon reaching zero level of total ammonium nitrogen content in water, hydrobionts are planted in the pool and their cultivation is started. Level of total ammonium nitrogen, dissolved oxygen, the amount of active sludge is controlled; when threshold values of active sludge are reached, water with active sludge particles is drained from the pool, to replenish drained water, purified water is added to the pool until the amount of active sludge is brought to a safe level for cultivated hydrobionts. To feed microorganisms, beet molasses is added to the pool water in amount of 5–18 g of molasses per 1 g of nitrogen in the water, until concentration of total ammonium nitrogen is reduced to a safe level for grown hydrobionts.

EFFECT: invention widens the range of methods for preparing a medium for growing aquaculture objects.
