One of the most energy-consuming links in obtaining downstream sturgeon fry at VEDORZ is rearing larvae to viable stages in the basins, for which the plant uses 240 ICA-2 basins and the Kubanrybvod system with a total area of 1200 m2. Under VEDORZ conditions, a flow-through water supply system is used, in which the consumption of water in the pool should be at least 3 - 4 dm3 / minute. As a result, 0.18 - 0.24 m3 of water is used for the operation of one pool with a volume of 2.5 m3 per hour, which, in terms of all pools, is 43.2 - 57.6 m3 / hour. Taking into account that the average time for the transition to mixed feeding of larvae of different sturgeon species, depending on the water temperature, is from 6 to 14 days, only during this period, under recirculation conditions, it is possible to save 4.5-5.0 thousand m3 of water.
